It seems that there's no specific library but I have no idea which exactly. I use last hibernate version(4.1.8 final). I've tried to link all libraries from hiberante but it doesn't help. Any suggestions?
The JAR file(s) with webapp's runtime dependencies have to go in /WEB-INF/lib folder. The exception which you're facing suggests that this is not the case. So, to fix it all you have just to make sure that the JAR file(s) are been dropped in the right place.
A common beginner's mistake is that they fiddle in the Build Path property of the project in order to add runtime dependencies. That's thus wrong. It only adds compile time dependencies. You need to undo every change which you made in there in an attempt to solve this problem, or it may still collide.

I installed eclipse luna a week ago and worked every day with it until the javadoc broke yesterday.
When i hover on a class or method, the popup shows, with the right dimension apparently, but it's blank.
This problem happens for classes that i wrote, classes that come from maven dependencies and classes from the jdk (like String).
I restarted eclipse, the computer, and it still doesn't work.
I didn't notice anything i did diferently that could have caused this.
I looked at the build path and for each jar, there is the source path and the javadoc path.
The javadoc view is empty also.
I don't know what to do. I can't work without the javadoc hovers.
Edit :
In the error view i saw that the first time i try to hover i get an Internal error on "org.eclipse.jdt.ui" :

Edit 2 : it still doesn't work !
I uninstalled eclipse and reinstalled a fresh one, i wiped the workspace, there are no changes.
The problem is as the #Pavel Horal said
You should switch your browser to a different one , the default browser is IE by modifying the eclipse.ini file eclipse.org/swt/faq.php#browserspecifydefault
or just add
-Dorg.eclipse.swt.browser.DefaultType=mozilla
at the end of your eclipse.ini file.
Or if you are more comfortable with UI interface of the eclipse you can use this help to change the default browser HELP.

I have used mocking in my tests.The framework used is JMockit. Any help is appreciated.
I don't know why this duplicate loading of "attach.dll" occurs (will investigate later), but you can avoid the problem by using the "-javaagent" JVM initialization parameter. See here for details.
I'll give it a try. Here it says something like:
Caused by: java.lang.UnsatisfiedLinkError: Native Library C:\Program Files\Java\jdk1.6.0_25\jre\bin\attach.dll already loaded in another classloader
My guess is that you try to load the dll twice? Once maybe it's loaded as a maven dependency and once as from the jdk?
Try adding tools.jar to your classpath. If you've downloaded a JDK, it is typically in Contents/Home/lib/tools.jar under your JDK root. If you're using Eclipse, check out this answer on another question.

try adding source folder to your classpath. If you use eclipse, right click test file and select Run configuration under Junit test and select classpath and add your source folders to class path.
Check class WPException. Usually your IDE should show you if something is wrong with the java file but not with the class file - either it wasn't compiled or missing (the error is triggered when the JVM can't find the class) for some other reason, one of them could be, like bluelabel mentioned, a problem with the PATH.
I know this is old post...but may help someone else...
whenever I have faced this issue only problem have been the java version eclipse is defaulted to - which is the eclipse jre.
Fix - change to the proper jre installed on your machine !

I've added the jar file to the build path, and also added the inherits node to the *.gwt.xml. What am I missing?
I had this issue. I attempted many different fixes, but in the end it appears that there were some resources (JavaScript files and CSS files) which were not being loaded because of authentication issues (I was using Spring security and forgot to provide access to some subfolders of my web application).
There are some important processes you need to go through when troubleshooting GWT apps. They can cause issues even when there aren't really any.
Clear your Browser cache
Use the code server query string (e.g. http://127.0.0.1:8888/index.html?gwt.codesvr=127.0.0.1:9997)
GWT compile your code
It could also be an issue with Google Chrome (if that's what you're using). The guys at SmartGWT suggest you don't use Chrome for GWT development.

Today I programmed myself a Little game, which I compiled into a jar through Eclipse - I made sure its a executable jar, or runnable jar or however you want to call it.
I've sent the jar to a friend of mine, but oddly he's not able to open it.
He's always receiving the "Can not find main class" error, which shouldn't pop up since it works perfectly for me. I've already googled but was not able to find a answer.
If you're interested, you can take a look here, if it works for you:
http://www.file-upload.net/download-3939961/WidzDeluxe.jar.html
Now the question I have is kind of obvious I guess, is the error only for him or do you all have the same problem? What's the cause of it?
If people wish, I also upload the code.
You have compiled class files bundled inside this jar with a different (higher) version of Java. Presumably it was Java 1.7 and the friend of yours is trying to open it with Java 1.6.
Here is the stacktrace I received trying to open your executable jar with Java 1.6.0_21:

Could not find the main class: NewJFrame. Program will exit.
One possible solution that came to my ming would be to set the compliance level to let's say 6.0 in Java Compiler settings in Eclipse. That should to the trick.
I had this same problem, found I was compiling the program for Java 1.7. I ended up updating Java on all my computers that I was running it on and it worked great.
