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.

Issue using couchbase lite java on Windows XP

I am using couchbase lite for java (couchbase-lite-java-1.3.1) for my JavaFX application.
My code is working well on Mac OS X, Windows 7/10.
Now I am trying to make it work on Windows XP but I am getting the following error:

I use the same Netbeans project for Mac OS X, Windows 7 and for Windows XP.
Do you have some info about this problem? It is trying to use a procedure in CouchbaseLiteJavaForestDB.dll...
Thank you.

I reached out Couchbase Lite dev team and they advised me to remove ForestDB jar lib and to use SQLite as storage engine. Now it's working well on Windows XP.

The problem is that the class com.sun.javafx.Utils was moved to com.sun.javafx.util.Utils package in update 60 of Java 8.
I see that you use ControlsFX in your code. Then, take a new version of ControlsFX solve this problem.

After spending roughly 8 hours on this, using three different operating systems (Ubuntu 32, 64 and Windows 8.1), the issue was with Java. Apparently, any version after 8u40 will not work with this.

Exception running application StartUp
However i am not even using the Hibernate library, i am using JPA, i tried searching for "Session", "hibernate" and other strings but i can't find any of those and yet it is throwing this error.
These are the libraries i am currently using:
I was using hibernate before but i had to use JPA, so i removed everything that had to do with Hibernate.
The stacktrace is referencing to some of my files but nothing on those lines has anything to do with database management.

Have you added Hibernate JAR's to the lib directory of your server by any chance?

Well the stack trace says clear enough that "gui.GraphicApplication.(GraphicApplication.java:28)" is referencing it, so look at that and fix it?

Java Applet Running in Netbeans, but won't run in browser

Exception: java.lang.RuntimeException: java.lang.NoClassDefFoundError: org/jdesktop/beansbinding/Property
I have read some places that I need to right click on my project and then go to the libraries. Once I'm there I do have Beans Binding Library installed. Also there was somewhere else where a beans.jar file is installed (which I have).
How do I solve this run-time exception?

Caused by: java.lang.NoClassDefFoundError: org/jdesktop/beansbinding/Property
Add the Jar containing the org.jdesktop.beansbinding.Property class to the archive attribute of the applet element.
