I am new to RapidClipse IDE as my organization requested that I study and develop with it. After having installed version 2.3.1 windows edition, I created a project but the UI designer is showing an error and the widget palette is not showing anything. Below you can find the full stacktrace:

I have been able to solve this. Its probably a bug from the developers of RapidClipse. this is what i did:
The UI Libraries to display the designer and the pallette does not download when you create the project, so you will have to download the following:
xdev-server-aa
xdev-server-ui
from maven repository and include them in your library path. then you right click the project select maven and update project. Restart the RapidClipse IDE

I am using eclipse mars and seem to be able to use JPA in a stand alone app (no glassfish/jboss) by just using these libraries:
eclipselink.jar
javax.persistence_2.1.0.v201304241213.jar
org.eclipse.persistence.jpa.jpql_2.5.2.v20140319-9ad6abd.jar
But when I build and deploy my app I keep getting the below errors. Would my version of java matter? I'm using 1.6.0 24 32 bit on my production board and my IDE is a 64 bit system. The above libraries were included when I created a test project in NetBeans so I was able to use JPA in NetBeans fine as well. Am I missing additional libraries or perhaps something is wrong with my deployment? any advise is greatly appreciated.

I'm trying do create a JavaFX application based on Gluon. Therefor I'm using Eclipse with the Gluon plugin.
I need to say that I am new to Gradle and JavaFX as well, so maybe I disgrace myself with this question, because it's too obvious.
I created a fresh project with the Gluon project wizard that I am able to compile and start via the Gradle task "run". After some toying with the project I produced an error that I would like to debug step by step with the eclipse debugger.
So, how can you debug a Gluon/Gradle application? I'm also interested where I can configure the Gradle tasks. I see the preconfigured ones in the task list, but can only execute them by doubleclick. There isn't even a context menu. One idea was that there was a debug gradle task in the list, but I couldn't find one so far.
UPDATE:
I)
I need to add that I want to use Gluon ignite with dagger and my application can't be started by the eclipse run menu, because the code generation for the dagger modules has not been performed. Debugging and launching without Dagger seems to work. So my question is bit more specific than I thought...
II)

Has anyone else experienced this and know how to fix it?
type java --version does the version agree with 51.0
refer to stackoverflow.com/questions/10382929/…
you may need to install the latest jdk, or you can export the JAVA_HOME for the IBM JDK and add $JAVA_HOME/bin to your path
I was messing with the JRE setup on Eclipse. Originally the project was set to 1.6 and when set to 1.7, my program started showing a lot of errors. So when i switched back to 1.6, all the compile time errors vanished but i have a new problem now.
This was shown on the console when i tried to run the started class containing the main function. The .class files all exist. Please advice.

Version 51.0 means the are still class files compiled with Java 7. This files wont run with a JRE 6. You have to recompile them first (Rebuild project or clean compile using ant/maven).
Check if java versions match in your Java Build path and Java Compiler in Project properties. I think you compiled with 1.6 and is trying to run with java 1.7
I'm trying to generate a "Top down EJB Web Service" implementation from a WSDL with WAS V7.0 Developer Tools. (Server runtime WAS 7.0, web service runtime IBM WebSphere JAX-WS.) After selecting my EJB and EAR projects and specifying further options, I always get the following error, regardless of my options:

Going through the exact same steps in Rational Application Developer 7.5.1, I can successfully generate an EJB web service implementation with an HTTP router module for my WSDL. So I think this problem might be related to WAS Developer Tools.
Do you guys have any idea why I'm getting this error? Any help would be much appreciated.
Thank you,
Csaba
Make sure you are using the WAS 7.0 JVM when you run the wsimport. You may have several JVMs on your workstation. The JVM under <was install>/java is the one you want in your PATH ahead of all others when using the command.
It wasn't enough to configure Eclipse to use IBM's SDK for projects, I had to start Eclipse using IBM's JVM. I've edited eclipse's config file (eclipse.ini) and added IBM's JRE.
