I am running Eclipse Kepler using the J2EE download on Mac OSX Mountain Lion. If I create from scratch a simple JFrame and add a JPanel to it, I am then unable to set the Border type using the properties inspector without crashing the WindowBuilder.

WindowBuilder Core 1.6.0.r43x201305211944 org.eclipse.wb.core.feature.feature.group Eclipse.org

Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

The following error dialog appears :-

Designer [1.6.0.r43x201305211944.201307191313]: Not implemented (java.lang.ClassNotFoundException: sun.lwawt.macosx.CViewEmbeddedFrame cannot be found by org.eclipse.swt_3.102.0.v20130605-1539)

I did exactly as you suggested, and it worked just fine.

Note that the ClassNotFoundException you reference is being triggered by Eclipse and reported by WindowBuilder. A ClassNotFoundException like this indicates some sort of incompatibility with your Java environment. In fact it looks like it is a known Eclipse issue.

I have just performed a fresh download of Kepler J2EE Eclipse and this time installed the current WindowBuilder Pro Integration version. I get the same error.

What versions of Eclipse and Java are you running to get it working please ?

Thanks

Dave
