I am very new to Java. I am trying to use jsoup in a small project. I couldn't set up my netbeans to use it.
I have opened a folder for third party libraries in C:\Users\muhammed\jarlibraries and I have put jsoup-1.7.2.jar in it. Then I right clicked on libraries and selected add jar folder. Now my project looks like this;
As you can see from the image above, netbeans cannot resolve Jsoup when I say Fix Imports. Am I doing something wrong here? How would this process work?
Why do you placed your libary into a package? Thats not how you do that. Do this instead:
Go to project properties by right clicking on project.
Then click on Libraries tab, You will see Compile, Run, Compile Tests, Run Tests tabs.
Click on Compile tab (the first tab, selected by default)
Click on Add JAR/Folder button at right
Then browse and select the jar file(not the folder) you want to include. Included jar file will show on the following box of Compile tab.
Click on OK button.
Finished.
Than it will be added to you project and classpath.
You imported a complete folder into the project, but you only have a single jar file.

I have no experience with package structure. I added two external libraries (from Joda) to my eclipse project. The code makes use of the libraries with no problems. However, when I export the Archived File and open it on another computer, the libraries are no where to be found. Much sadness.The error looks like a little red exclamation point next to my project in the package explorer. Checkboxes next to the libraries have been checked/applied.
Right click on your project
Navigate to build paths -> configure build path
In order and export tab check whether the library is in the list or not
If it is not selected, tick the Checkbox and click apply
Someone told me that I need to export it as a executable jar.
I set a lookAndFeel synthetica theme for the project.After that it is not working(jar file in the dist).
Again I removed it and tried.Then it worked. I did clean and build.
Tried several themes. They all workedd in the project. But did not run in the dist.
What should I do? Please help me..
I have experienced this before in my projects. Most of the time it happen because of using icons and images.
When /Icons/calculator.png image in your package, it is not wrong in netbeans like this getClass().getResource("/Icons/Calculator.png").
this is working on netbeans. but not in jar file. you need to rename Calculator.png.
use jar file in console (CMD in windows , shell in linux) with this command
java -jar adress-jar-file/jarfileName.jar
then see error in console.
Just Right click on yoru projet in netbeans and select Set Configuration then Customize in the window that appears provide your Main Class by clicking the browse button or writing it manually and Clean and Built again
Plz make sure some points.
1) You have set main class properly.
Right click on Project-> project properties-> Run-> set Main-Class
2) You have set theme path properly.
3) Your themes are not corrupted.
4) You have build your jar properly.
Right click on project-> clean and build(Note: Do nothing while it finish building jar)
5) Your lib folder not corrupted (if it is present).
It looks like there maybe something wrong with your setup. In your project properties, under libraries have you by chance added synthetica.jar as a required jar. but m not sure try it
but you can simply do,
you could create lib folder manually in your project folder and then paste that jar in that folder then through netbeans go to your project then right click on libraries and then browse to find your project folder open that then click on lib folder that you have created open it then click on jar that you have pasted and that jar file will be added to your project.
I could resolve my problem.I'm sorry that I was used trial version Synthetica.jar. after I bought it and done every thing from the beginning. I resolved it. Thank you for your contribution to resolve it.thank you
I have downloaded common.codec binary jar file. Now I want to use the class org.apache.commons.codec.binary.Base64. But this folder contains four jar files namely common.codec-1.7.jar,commons-codec-1.7-javadoc.jar, commons-codec-1.7-sources,commons-codec-1.7-tests,commons-codec-1a.7-test-sources. Now which path should I mention in class path? And I tried with all the jar file paths and imported in my program but failed. Please tell me where to place this downloaded jar file and how to use it in my code.
You can use common.codec-1.7.jar if you are using an IDE like
Eclipse:
1.Right-click your Project.
2.Select Properties.
3.On the left-hand side click java build path.
4.Under Compile tab - click Add External Jars button.
Netbeans :
1.Right-click your Project.
2.Select Properties.
3.On the left-hand side click Libraries.
4.Under Compile tab - click Add Jar/Folder button.
or if you directly compiling classes without IDE you can do as #S.R.I mentioned in comment.
I have downloaded a messaging framework library from eneter.net. In eclipse I have imported the library to the /libs folder. I right clicked on the library and then added it to the build path. I know that the code is right, but when I compile it and try to run it, it says that that it can't find the classes. Odd thing is when I open up the apk in a zipping program, the library wasn't added to the apk at compile time. Does anyone know why this would be?
Try right-clicking your project in Eclipse's project explorer, then hit Properties. Go to the tab labeled Java Build Path and hit Add Library... (or if it is a jar file, Add JARs... if you already added the Jar to your project and Add External JARs... if it is not yet within the project). From there, browse for the library you wish to add and add it to the project. Re-compile (maybe even Project->Clean) and try running it, and see if the library gets added now.
I right clicked on the library and then added it to the build path
That is not necessary, as of the R17 version of the ADT plugin in Eclipse. Moreover, it may cause problems if you do it.
Does anyone know why this would be?
Possibly because there is a typo in your directory name, such that it is not named libs/. By adding it manually to your build path, you are compiling against it, but the build tools are not adding it to the APK.
Is the library in the form of a complete Android project? This is then used with another Android project by going to the Properties of that project, selecting the Android tab, and then finding and selecting that library in the lower window.
How do I use simple in eclipse?
Do I add it to the JDK?
http://simple.sourceforge.net
The web site seem to have allot of info on using the methods but little on setting up the library.
I have used C and C++ to set up external libraries before but the Java set up confuses me.
Thank you!
In java world, in order to be able to use third party libraries, what you need to do is to add them to your project/application's CLASSPATH. In case of Simple, its library file is simple-xml-2.4.1.jar that is located inside a folder "jar" within the simple-xml-2.4.1.zip that you would download from Sourceforge.
Download and unzip the
simple-xml-2.4.1 Archive. (ZIP file).
Note that it has a Jar folder that
contains simple-xml-2.4.1.jar - that
is the library eclipse and other IDES
would use to set up the CLASSPATH
Goto your project in project
explorer.
Right-click on the project name and
select "Properties". Alternately, you
can click on the project name and
type "Alt+Enter". A window will
pop-up.
In the window, select "Java Build
Path". You will see several tabs,
including "Source", "Projects" and
"Libraries".
To add simple-xml-2.4.1.jar to your
project, click on the "Libraries"
tab. From there, you can add either
internal jars or external jars. The
"Add External Jar" would be to add a
jar that's on your computer somewhere
. So choose that button, browse to
where simple-xml-2.4.1.jar is located
and make sure to add it to your build
path
