ExceptionInInitializerError exception when executing the built executable jar

I have tried to recreate the cloud balancing problem on a simple Java Application command line app. I didn't use any dependency manager, I just imported all the libraries provided on the Optaplanner distribution that can be downloaded on the site.
On IDE, things are working just fine. Problems happen when I execute the built executable jar file, I always got this exception:

Initializer Error Using Netty 4 with RoboVM

I am trying to simulate my existing project on ios via robovm. The java project starts running, but quickly encounters a problem with Netty (4.0.25) libraries that I am using. I am using the latest version of RoboVM.
Here is the error:
java.lang.ExceptionInInitializerError

... 13 more
Here is the line pointed to in Netty:
} else if (PlatformDependent.hasJavassist()) {
It seems to me that Netty is trying use code that is unavailable in RoboVM. This application runs fine in Android or Desktop versions, and the RoboVM version seems to run if I remove Netty references. Any help on how to make the two coexist greatly appreciated.

Run java applet offline: Exception in thread "main" java.lang.NoClassDefFoundError

I just downloaded some java applets from this site: http://www.surendranath.org/Apps.html to run them offline on my laptop. Take for example this one: http://www.surendranath.org/Applets/Oscillations/Lissajous/Lissajous.html
By inspecting the source code I downloaded the file: wget http://www.surendranath.org/Applets/Oscillations/Lissajous/LissajousApplet.class
Then I tried it to run it on my ubuntu box via gappletviewer-4.8 -code LissayousApplet.class
However I got the following error message:
Exception in thfully qualifiedread "main" java.lang.NoClassDefFoundError: loaded class LissajousApplet was in fact named Applets.Oscillations.Lissajous.LissajousApplet

at gnu.classpath.tools.appletviewer.Main.main(libgcj-tools.so.14)
So what is the correct way to run this applet offline? Running it online within my browser and the icetea plugin works. However I need a way to run it offline.
Edit
Trying the fully qualified class-name results in:
gappletviewer-4.8 -code Applets.Oscillations.Lissajous.LissajousApplet.class -codebase codebase="../../../"

Not able to start websphere server 8 in Rational application developer 8

I am using Websphere application server 8.0.0.2 and Rational application developer(RAD- 8.0.4)
When i try to start the WAS from RAD servers tab. It worked fine for two to three times and later it started giving
Exception in thread "main" java.lang.NoClassDefFoundError: RESOURCE
Caused by: java.lang.ClassNotFoundException: RESOURCE

Could not find the main class: RESOURCE. Program will exit.
I reinstalled WAS and tried, it was working fine, i was able to start the server properly for 1 or 2 times, then again the same error after i reopened RAD.
Please help.

Trying cleaning the server:
Go to the servers view, right click on the server and select "Clean...". This dumps all the cached application and state files. This will then start the server and publish whatever project is on it.
