I'm using NetBeans 6.8 on Windows 7. I upgraded from WinXP and NetBeans 6.7. Now my existing java web app project is no longer able to import/find the packages I've developed - I receive a 'Package ,blah. does not exist' and yet the packages do exist, worked fine in NetBeans 6.7 and the project still compiles and runs OK.
I've tried changing the Java Platform/JDK from 1.6.0_10 back to JDK 1.5.0_22 but I still receive errors package does not exist.
All other 'standard' libraries and packages are able to be imported and used OK ... eg Struts, Hibernate
I have fixed this problem many times by clearing the NetBeans cache.
1) Close NetBeans
2) Go to "C:\Users\.netbeans\6.8\var\cache
3) Delete everything that is in this directory
4) Open NetBeans and wait for it to re-scan your projects
At this time, this has fixed my problem. I do need to do this every once and a while, but if I don't change anything in the project's structure, the issue does not come back, and I can develop in peace!
Hope it helps someone in need.
Solution was to create a new empty web application, check the existing project out from SVN, regenerate the build-impl.xml & configure the library references.
All is now importing and referencing OK
I do not have an explanation as to why the problem occurred the first time this project was created
I had the same issue with Netbeans 7.0.1. Suddenly after some work I could not compile my project anymore, because a major package "does not exit" anymore. All my projects settings (build properties, project properties, dependencies ) seemed ok for me.
The only (bad) solution I could find is, to copy the relevant module to a new name, remove the old and re-create the module again by copy/paste of packages. Now it works again.

I have seen the error when I had the same jar installed twice - as compile library and as a test library.
As the result, many of packages became invisible.
After removing the jar from compile libraries everything become visible.
In the project Properties, under "Libraries", "Compile" tab. Do an "Add jar/folder" of the "src" directory if it's a regular Java project. If it's JSF, use "src/java" instead.
just change s by S in System.out., is simple but i think is your problem

I am having trouble setting up the build path of my java project. I am currently in a Co-Op IT position so I am somewhat new to all this. My background is mostly in C++ and I am learning java on the fly. I am also somewhat new to Eclipse (Kepler service release 1).
I am working on a bug on an existing program and need to get the program to build so I can work on it. When I add all of the external .jar files that I know for a fact are the right ones, I am getting this error on two of them :
"Archive for required library: '(location of file)' cannot be read or is not a valid ZIP file"
Two of the other full time guys on my team have gotten the program to run with those exact same .jar files, one running Eclipse Indigo and the other running the same Kepler version as myself. I also was able to open the two .jar files manually and everything appears to be there. After every trial trying to fix this, I have refreshed, cleaned and restarted eclipse. The two other full time guys said they have never seen this error. I would like to get some insight on this from anyone who has any similar experiences so that I don't have to use up much more of their time.
I Had this issue, just fixed by deleting .jar files from Libs directory then copy->paste original Jars again. Then do a complete clean -> rebuild
I got this problem, took help from following link solution
which basically says to
1. delete the corresponding maven download folder
2. maven>update project in eclipse
In my case I deleted hibernate folder, since i was getting error related to hibernate-validator.jar
I had the same error here. What I did to resolve the problem was close and reopen the project.
I got the same problem and found out the root cause is the JDK in my linux shell is set to 1.6, but in the eclipse, the JRE is 1.7.
Using Eclipse without m2e features (Standard Edition) helped me.
Similar problem with Spring toolsuite
Just came across this link that shows a way to get unblocked.
In preferences dialog box go to
Java->Compiler->Building
and change Incomplete build path to "Warning" (from default "Error")
This can be done globally (for all projects), or on a project by project basis.
Check the jar's file permissions/ownership.
I had the same issue on eclipse installed on Linux and fixed it by setting the file permissions right.
In my case ..worked after removing this from spirngrest-servlet.xml file.
<prop key="net.sf.ehcache.configurationResourceName">/Sysehcache.xml</prop>
I think it had to do with default location of maven repository of jar files.
Been at it for 3 days. finally solved it.Hope it helps anyone.Just look for similar think in your spirngrest-servlet.xml file. Good luck.
I just tried the following and it worked:
Close eclipse as there might be some files eclipse is accessing and you won't be able to delete.
Delete all the libraries installed in the maven repositories folder: ".m2/repository"
Open eclipse and update your project(Alt+F5).
What did we just do? : This is possible that the existing libraries in the local repository are erroneous and maven tries to open which it fails in. We have now deleted the already existing library and with the project update, Maven will download the library again which should resolve the issue.
i fixed this by just deleting everything inside of the /Users/username/.m2/repository folder. not the repository folder itself. and then running a mvn clean package in the project folder
Netbeans is not importing a jar from another project. The classpath is fine, the project compiles fine but the editor show several errors in project because it cannot locate classes inside that jar. I've already rebuilded the projects and clean Netbeans' cache (~/.netbeans/7.1.1/var/cache/)
Netbeans version: 7.1.1 and also 7.0
OS version: MacOS 10.7.3
The problem lies with the Netbeans' code editor. My project compiles and it's packaged just fine. I have no problem on that. I have this annoying error messages (eg. red background) in the code editor with no reason.
A workaround I just found: Renaming the dependency project (with refactoring) and adding the new jar to my project do the trick. Still I don't know what happened.
I just had the same problem in NetBeans 7.2.1 today. I could build the project fine but got error markers in the source files and in the Projects tree listings. It seems as if the compiler when you build a project uses a different classpath from the compiler that works in the edit window.
In my case I found we had the same package and class names for different classes in different jars. I don't know if this is relevant or just a red herring.
I still had an error in one project that used these two jars. It seemed like it could only see the classes from the second jar listed in the pom.xml file (we use Maven). I commented out the second jar & rebuilt, then uncommented that second jar & rebuilt and suddenly all of my errors went away.
So I don't have a definite solution but removing and reintroducing a dependency worked for me.
How you import jar file ? You have to right click Libralies in Project Panel and click Add JAR/Folder. And select jar file which you want to import.
I think you have wrongly imported the jar file. Try out the below steps to add jar(s) to your classpath properly.
1. Select your project from the Projects explorer.
2. Right click -> Properties.
3. Select Libraries from Categories list.
4. Click on Add JAR/Folder button.
5. Add your jar(s) & click on OK to finish the process.
Now, it should resolve the reference issues
You mentioned, the editor shows errors because it cannot locate classes inside that jar. Well, are you sure you are using the right jar or right version of jar ? Eclipse is not able to locate any of the classes or only few classes ?
I wish my answer would help fixing the issue (even if too late :) )
Indeed, I have a maven project with two modules. Module1 that contains the class com.x.y.MyClass and Module2 where I'm trying to import com.x.y.MyClass.
It compiles fine, and I can run unit tests using netbeans, but the errors in the editor were embarrassing. So I add Module1 version and packaging type to the pom.xml of Module2 and that fixed my problem (I know, it's very bad to hard code a module version, but at least, I can work without worrying about the editor list of errors)
Cheers !
This is definitely too little too late, but I had this problem today with Netbeans 7.2. All jars were in place, the code was compiling from the build menu, but Netbeans was marking the files in error.
The same exact project was compiling fine with Netbeans 8.0.1.
The problem was with the "Source Root". I clicked on menu Window -> Debugging -> Sources (Alt+Shift+8) and I noticed that I had specified sources on some of the jar dependencies of the project that were no longer valid. Cleaning them up was a 2 step process:
Clean them up from the project files in nbproject dir
Clean them up from
%APPDATA%\NetBeans\7.2\config\Preferences\org\netbeans\modules\java\j2seplatform\Sources.properties
After clean up, I restarted Netbeans and everything was OK.
Hope this helps someone.
I had this issue with few jsf xhtml pages though there wasn't any error in the content of the page. So I opened each page and cut all content, saved the empty file then paste back all content and saved it. it solved the red marking error symbol for me.
I know this question is a bit old but for those who may be facing the same issue currently, hope this will help.
I faced the same challenge after moving my maven projects to a new directory. To fix the issue, I just simply
Renamed the new folder(the one containing my maven projects) just the same name as the previous folder.
Reimported the projects in Netbeans.
I downloaded the sample Restlet project and opened it in Eclipse. I instantly get this error:
Errors occurred during the build.
Errors running builder 'Google WebApp Project Validator' on project 'org.restlet.example.serialization.gae-gwt'.
java.lang.NullPointerException
What am I doing wrong?
I had this same error with my own project. In the Eclipse Project Explorer I right-clicked the project and chose Refresh. That cleared up the error for me.
This is a temporary, but repeatable solution someone on my team found...
Close project
Close Eclipse
Open Eclipse
Open project
I continually had this problem in combination with git. My git repository was in my eclipse workspace ( even though eclipse warns you not to do this ). Deleting the old repository, and creating a new git repository outside of the eclipse workspace, then cloning a fresh copy of my gwt project solved this problem for me. Hope this helps.
I'm also experiencing this error, but thanks to git comparing .classpath I noticed that I had removed a couple of variables from the "Configure Variables" list, but not from the Java Build Path. Once I removed it from the second list, the error was gone.
I got this error when I was using a workspace that was on an NFS and I had the same workspace open on two different vnc sessions. I closed out Eclipse on one vnc session and then restarted eclipse on the other. Then I went to the java build path and editted the gwt sdk and had it use the gwt sdk it was already pointed to and it stopped giving me that error. I didn't actually change the gwt sdk, just went through the motions of doing so. Hope this helps.
The problem was miss configuration of JRE, I just did the following:
Go to Build path configuration, select add Library, JRE System Library, select your JRE.
And there you go...
For me this error seemed to occur after a compile had failed due to lack of memory and eclipse had been restarted. However, after increasing memory (in the eclipse.ini) the problem still persisted. None of the above solutions worked for me.
The bizarre solution I found: our project here uses GWT 2.4, so I switched to 2.5 (which comes with the plugin - window>preferences>google>Web Tookit), re-compiled, switched back to 2.4 and, hey presto, it worked again!
(Another hour of my life I'll never get back!)
I have a Java Web Services project that was created in an older version of NetBeans, and I haven't accessed it in many months, so my paths and installed libraries are different.
When I try to open the project, I get a "Resolve Reference Problems" dialog, and two Reference Problems are listed:
"metro" library could not be found
"JAX-WS-ENDORSED" library could not be found
I have a fresh installation of JDK 6 Update 25 with NetBeans 7.0, and am running Windows 7.
What steps can I take to solve this? I don't even know where to start, as every approach I've taken so far hasn't gotten me anywhere.
Note: JAX-WS-ENDORSED does not appear in my Libraries listing, so I can't remove it. Something hidden is referencing it. How would I find this?
I just came across this issue and found some help from http://netbeans.org/bugzilla/show_bug.cgi?id=187145. Apparently, Netbeans will create the JAX-WS-ENDORSED library when a new web service is created. So go to File > New File, choose Web Service > Web Service Client and fill in dummy values (this can be done in a throwaway project). This client can then be removed, and Netbeans will have created the library with the following classpath entries:
java/modules/ext/jaxws22/api/jaxws-api.jar
ide/modules/ext/jaxb/api/jaxb-api.jar
These are relative to your Netbeans install directory (on OS X will be located in Contents/Resources/Netbeans within the .app). Alternatively, you could create the library manually using the entries above.
This only needs to be done once, as the library will be added to Netbeans Global Libraries list.
The best solution is to edit project.properties file and replace below piece of code.
Original property: endorsed.classpath=\${libs.JAX-WS-ENDORSED.classpath}
Replace with: endorsed.classpath=\${lib.JAX-WS 2.2.classpath}
In older versions of Netbeans there is JAX-WS-ENDORSED library in libs location.
Newer versions of Netbeans having JAX-WS 2.2 library in lib folder
** ALL THE BEST **
If it is still needed, I had the same situation when opened a netbeans 6.9 project in netbeans 7. There is no way to resolve the 'jaxb-endorsed' (in my case was jaxb and not jaxws) reference using the libraries window.
I found a endorsed.classpath property in the nbproject/project.properties file.
I still not sure what is its purpose, but in this property I found the bad reference to jaxb-endorsed.classpath, so I deleted, closed netbeans and opened again, and the reference problem has gone.
I already have Jaxb 2.2 library added to my project, so it is working good with the modification I did to the project.properties.
I hope it helps.
I had a similar problem : DO NOT DELETE THE JAX-WS-ENDORSED - remind me to downvote. I had to go to the imported project > resolve reference
problems dialogue > delete the references from there which were pointing to the old NB folders - pic :
and then create the throwaway web service as suggested by William Scott and then add the newly created jars :
Netbeans maintains a set of libraries, which are simply a convenient way to manage groups of related jar files. Start by clicking Tools > Libraries. You will see the library manager window.
You will see the options to add your own libraries if you have jar files downloaded. If you do not see the library that you are looking for you can download them and add them your self. Once the library exist in Netbeans you can go to the Project Explorer window and right click on the Libraries tab of your project. Select Add Library and you will have the chance to add the library that you added in the library manager.
You may want to right click on your project, go to properties -> Libraries.
Remove the JAX-WS-ENDORSED library, and try using JAX-WS 2.2
Also remove metro and try adding METRO 2.0
That may solve your problem.
You may also want to right-click on your web service references and select
Edit Web Service Attributes
Then on wsimport Options tab see if xendorsed is set to true.
UPDATE
You may need to close netbeans and then open it again, and it may work. I was having a problem similar and I just did that and it worked.
The only difference, and it may not be needed, is that I also added the JAXB 2.2 library, but that was because I was trying to solve a compilation error.
I had same problem and Fix it by install soap webservice and and resful webservice in netbeans plugin
I fix it:
unistall netbeans.
delete HOME/.netbeans and HOME/.nbi
then install netbeans again
Old thread, different and effective solution... I just moved some projects from one system to another and got this error. With NetBeans v7.3+, go to Tools>Plugins, Available Plugins, then search for "SOAP". You should see "SOAP Web Services". On loading this library you'll get the JAX-WS-ENDORSED library. Restart NetBeans and you should be able to get a Clean Build.
Loading this package brings in a number of other libraries. On restarting the IDE you may get a notification that other packages now have available updates.
Do the following ( BTW in my case its NetBeans 6.9.1 )
1 Why this appeared now ?
Because i tried to open project on other pc with fresh copy of net bean
2 How the problem looks like ?
Jar Lib Not Found for JAX-WS-ENDORSED
3 Why it was needed at the first place and what its used for?
Well i have a webservice on same server/domain e.g localhost , so of course
it will work if i removed the web service from the folder in sources but i need it
4 What to do?
Try to add dummy any online free web service in form wsdl
like Some test web service or search for any other one
This is the source of my public free to use wsdl
5 What then ?
Just add it please
Now what ?
Wait for scanning project stuff it should be ok
you can re check from library properties of project
or see that there is no red/ or resolve references problem
in project properties
So what happened exactly?
Note: JAX-WS-ENDORSED it will be added automatically to your libraries
same methodology can solve other problems as well
I'm using Eclipse to learn to develop Android applications in Java. I haven't used Eclipse before.
The project I'm trying to use (supplied by OReilly as part of 'Android Application Development') is MJAndroid. When attempting to run the project, the Run fails, and the Problems tab mentions com.java.Object can't be found, and Eclipse asks me to check the build path. Clicking
Properties -> Java Build Path -> Libraries, the message 'Unable to get system library for the project' is displayed.
On a working project, Properties -> Java Build Path -> Libraries has an entry for Android 1.1, which if I click Edit, has the classpath container path of com.android.ide.eclipse.adt.ANDROID_FRAMEWORK.
It seems a simple matter of adding the correct container path to my non-working project. However Eclipse seems determined to make this as difficult as possible. No matter what I chose to add - jars, externals jars, variables, libraries, class folders, external class folders, nothing seems to take the form of 'com.android.ide.eclipse.adt.ANDROID_FRAMEWORK' that the 'Android 1.1' entry on the working app has.
How can I add this namespace to my project so it resembles the working one?
I'm quite sure it's a problem with Eclipse's somewhat odd user interface. Frankly there' nothing I'd prefer more than a file to modify and set such information - my background is in Python, and the whole eclipse environment seems an unnecessary burden.
I had faced the same issue when I imported a sample code downloaded from the internet. I am using android sdk 1.5 with 0.9 ADT plugins. Here is a simpler way to fix the andoid library reference issues
Right click on the project which has
issues and select properties
Select the appropriate Android build
(1.1, 1.5 or 1.5 with google api) and
say ok
Again right click on the project and
select "Android Tools > Fix Project
Properties"
Fix the imports once (if required)
Refresh the project and you should be
ready to go without any manual
editing
I faced this same problem after importing a project through GIT. The problem was that I didn't have the same target android platform installed, and the build path somehow got corrupted.
The first obvious thing i did was changing the target sdk in the project.properties, but even after cleaning up the project and Android Tools > Fix Project Properties, it didn't help and I was still getting the build error.
My solution after wasting close to 1 hour trying to figure this out?
RESTART ECLIPSE
Everything worked fine after that. Eclipse is pretty fickle. Only through years of experience you'll then understand her well. :)
Had the same problem and it turns out the Android SDK Location was not set which was a really simple fix. Go to Window->Preferences, click on 'Android' on the left hand menu, fill in the location of the Android SDK (e.g. C:\Program Files\Android\android-sdk) and click OK. Everything worked fine for me after that.
Found the answer in this set up guide: http://developer.motorola.com/docstools/library/Installing-Android-Dev-Environment/
Sometimes Eclipse can get a bit funny (technical term) with classpath container resolution.
You have a working project in your workspace, so you can rule out plugin installation issues. You could try opening the .classpath file (hidden by default, select the triangle in the top-right of the Package Explorer view, select Filters... and uncheck .* resources) and manually adding the container declaration.
`<classpathentry kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/>`
You may then have to close the project and open it again (right-click->Close Project) before Eclipse recognises the change.
You may also find that there is an Android builder and/or nature. If you compare the .project files for the working and non-working versions you may see entries for Android builders/natures. Copying the relevant entries may resolve the issue.
sometimes, eclipse can help you.
In Android projects, click right button on the project-> Android Tools -> Fix Project Properties.
It's usefull in class path errors!!
Luck!
I would verify you have the correct version of Java installed as well as the Android SDK. I would recommend installing/reinstalling the ADT plugin in your eclipse, makes it alot easier to create the android project.
http://developer.android.com/sdk/1.5_r2/installing.html
Also. I guess the path of the Android SDK must be setup correctly. This happened when I was overloaded with projects and I decided to create a new workspace copying some existing stuff into it.
Seems that the new workspace requires you to setup these details too once again
Is that setup properly?
