conflit version java :UnsupportedClassVersionError: Bad version number in .class file

I created a runnable jar with 1.5.0.07 java version, I deployed it to a server which runs with the same version of java,
I had two methods which use the same spring jdbc , when I run the jar in the server the first method works fine but the second return this error :

When I googled this problem, I find that's a problem of conflict different Java JDK but I don't get it because I have the same version of java in my project and in the server.

Oracle tutorial "Fancy Forms with JavaFX CSS" not working?

So I did the tutorial and everything went well, until i tried to run it. I didn't find a problem with the code and since it didn't work eventually just decided to directly copy the Oracle example project to the Netbeans projects directory, and im still having the same problem.
The project builds without errors nor warnings, but doesn't run and gives the kind of error message i don't have any clue about with my java skills.
So below is the full error message. The project can be downloaded here. I just recently downloaded the newest versions of Netbeans and JDK so that should not be the problem. Please help me out here, is there an error in the tutorial or did i do something wrong?

Exception running application login.Login
Java Result: 1

You have a NullPointerException at this line of code:
scene.getStylesheets().add(Login.class.getResource("Login.css").toExternalForm());
The code is ok. Did you somehow mess up the file names or paths? The css file does not seem to be found.

Jenkins Build Failure. ERROR: Failed to parse POMs

Hi I'm having this problem with Jenkins when trying to use it with a maven build project.
This is the error log.
Any help would be much appreciated.
I looked through older questions and none of them seem to answer my problem. I'm not using a repo, just local.

Where can I put my Jar file so that eclipse RCP can see it?
Oracle version- 10g express
OS: windows 7

Where can I put my Jar file so that eclipse RCP can see it?
In an RCP project you can not include JAR Files directly. One way to include is create separate plug-in project from JAR file and include that new created plug-in as Dependency.
Please Refer Cannot connect MySQL in Eclipse RCP IDE

If you unpack a jar-file the resulting files needs to go into WEB-INF/classes.

Not in WEB-INF/lib.
Try WEB-INF/classes.
