I am using Eclipse, Helios Service Release 2, Build id: 20110218-0911.
I have created a new dynamic web site, I have added google app engine sdks in it. now i shows the following msg in problem window,
Classpath entry com.google.appengine.eclipse.core.GAE_CONTAINER will not be exported or published. Runtime ClassNotFoundExceptions may result.
due to this, jar files in sdk are not coming in lib folder of WEB-INF,
any idea how to solve it?
Right click on this warning in the problems (or markers) view and select quick fix. There is a quick fix available for this problem that will tag the classpath entry for inclusion in the web app, which is what you want. You can also control what's included in the web app by using Deployment Assembly page under your web app's project properties.

I am desperately trying to build a little Vaadin project with login secured pages/views. I have found vaadin4spring and thought I could start based on the security sample. However, after importing the project and running it, I am receiving the message (without any changes at the project):
Failed to load the widgetset:
./VAADIN/widgetsets/org.vaadin.spring.samples.security.Widgetset/org.vaadin.spring.samples.security.Widgetset.nocache.js?1424243461387
I have also tried to compile the widgetset manually, which wasn’t possible at the beginning (missing WebContent folder). After converting the project to use WebFacets and adding Dynamic Web Module the compilation was possible. But the widgetset related error message was still the same.
Can anybody help me with this problem? I have the feeling that it is just a little thing I am missing.
I think you have imported the sample somehow wrong, because you are talking about WebContent folder. I bet you are using eclipse (because of WTP related WebContent folder).
Delete the old project from workspace and possible settings files eclipse created
Choose File->Import->Maven->Existing Maven Project
You probably want to make one fresh install before you start to play with the project: from the top level "parent-pom" project, choose with right click: Run as -> Maven install. Get a cup of coffee, the build will take a while.
Enjoy!
To start e.g. the Security sample you seem to have tried, just execute the main method from org.vaadin.spring.samples.security.ApplicationInitializer. In eclipse, right click on the class and choose Run as Java Application and the app will launch with embedded Tomcat at http://localhost:8080/
I successfully cloned an web application project from Github to eclipse Luna.
When I try to deploy the cloned project to google app engine, eclipse does not recognise it as a web project. I realised that it was missing the appengine-web.xml file.
I created one under directory WEB-INF in War,
I saved it but when I try again to deploy, still eclipse says that the project is not an app engine project.
What could I be possibly doing wrong?
Since you do not provide the exact error message, I list several possible causes:
Right click on your project, select "Google" option, then "App Engine". Make sure that "Use Google App Engine" checkbox is checked.
In your build path, make sure that "Allow output folders for source folders" is checked and the correct folder is specified (i.e. "MyProject/war/WEB-INF/classes".
Make sure that you are logged in Google with the correct account before you try to deploy - your current account is shown in the bottom right corner.
UPDATE:
This error indicates that your project is not a Java project. Select Project Facets in Properties. On the right side make sure that on the left side Java 1.7 is selected.
I am using the sample project code here that i've downloaded from the following:
http://javahash.com/spring-4-mvc-hello-world-tutorial-full-example/
Direct link here:
http://javahash.com/wp-content/uploads/2014/02/Spring4MVCHelloWorld.zip
I have Eclipse Kepler SR2 (J2EE), Tomcat 7 64-bit, Java 7.
The project does not appear to be a web project, so I add "Dynamic Web Module" version 3.0 and "Java" (version 1.7) to it. I right click, maven install, which appears to run fine. When I try to actually deploy it on tomcat, it does not give any errors in the console, but when the browser window pops up it shows a 404
http://localhost:8080/Spring4MVCHelloWorld/
HTTP Status 404 - /Spring4MVCHelloWorld/
--------------------------------------------------------------------------------
type Status report
message /Spring4MVCHelloWorld/
description The requested resource is not available.
--------------------------------------------------------------------------------
Apache Tomcat/6.0.39
That said, how do I get this "basic" example running in eclipse? Anyone able to get this working successfully? It feels like it should be more trivial than the 5 hours I've spent on trying to get this sample code working to no avail.
UPDATE:
Still continues to fail despite using Tomcat 7.0 server.
Download the sample, extract contents to workspace directory.
"Import Existing Project" in Eclipse
Since there is no "Run On Server" option, I right click on the imported project directory and hit "Properties".
I go to "Project Facets" and check 2 things: "Dynamic Web Module" (3.0) and "Java" (1.7) and hit apply then "Ok".
I right click on the project Spring4MVCHelloWorld and click "Maven"->"Update Project". Then I click "Run On Server".
There are no errors in the console, but the web browser that pops up in eclipse shows a HTTP STATUS 404.
I tried going to:
http://localhost:8080/Spring4MVCHelloWord/hello
and the same:
HTTP Status 404 - /Spring4MVCHelloWorld/hello
shows up, but the tomcat shows up as:
Apache Tomcat/7.0.53
Note that this is the 64-bit version. What steps am I missing? How do I get around this silent failing?
Apart from what Dimitri stated, your log seems to indicate that you are using
Apache Tomcat/6.0.39
That version of Tomcat does not support ServletContainerInitializer which your Spring web application depends on for configuration. Upgrade to a Tomcat version 7+.
It seems like the Maven update doesn't work for you (or for me).
First, go into Properties -> Deployment Assembly. You need to get rid of Web Content if it's there and add src/main/webapp (which is a maven convention). You also need to add the Maven Dependencies as shown below.
Finally, and this might not be necessary, delete the web.xml provided to you and re-create it by selecting and right clicking Deployment Descriptor in the Project Explorer and clicking Generate Deployment Descriptor Stub.
Also, make sure your Java Build Path in the Properties has a Java 7+ version of the JRE.
As far as I can see your controller only maps to /hello, which means your URL should be:
http://localhost:8080/Spring4MVCHelloWorld/hello
Another thing that might be interesting to you is that if your having problems with certain project facets (like Dynamic Web Module) not being recognized, you can usually fix them by righ clicking your project, opening the Maven menu and choosing Update Project.
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 know that tomcat is running because when I type http://localhost, the tomcat page dispay. My problem is I can't figure out why the wtpwebapps/myapp is empty, is like the eclipse doesn't publish it and when i type http://localhost/myapp, I get 404 error.
In the server overview :
Server Location is set to "Use Tomcat installation" | server path: the servers's folder | deploy path : wtpwebapps
Server Option : Publish module contexts to separate XML file
Publishing : Automatically publish when ressource change
I use eclipse Ganymede 3.4.2, tomcat 6.0, under Win7
Any help would be appreciated, thanks
your files must be somwhere, so start searching in:
<YOUR_WORKSPACE_DIR>\.metadata\.plugins\org.eclipse.wst.server.core\tmp<SOME_NUMBER>\wtpwebapps
I had a similar problem, when updating our project (.project and .classpath are checked in for convenience, but causes sometimes problems).
Console-Log in eclipse always says:
Error configuring application listener of class org.sth.ThisClass
java.lang.ClassNotFoundException: org.sth.ThisClass
The reason was that $WORKSPACE_DIR/.metadata/.plugins/org.eclipse.wst.server.core/tmp$NUMBER/wtpwebapps/$CONTEXT/WEB-INF/lib/classes was empty. The solution was to enter under Project Properties > Deployment Assembly an entry:
Source: /src
Deploy Path: WEB-INF/classes
If you use a Maven in your project, this is a solution for you:
Delete the project(s) in the Eclipse.
create project from Maven sources (select your workspace directory).
Check found pom.xml to import.
Restart the Tomcat.
Try to look into servers explorer and it will show you what state is your application at and if its deployed.
Since I had difficulty finding where this "server overview" is, I like to add that you just double click on a server under the "servers" view. I kept on right click and look at the "Properties" and was not getting to this information.
