SWT GroupLayout Problem - NoClassDefFoundError

[jschwartz73]

I downloaded Eclipse3.2-RC7 yesterday to try out your new GroupLayout for SWT. Everything installed and licensed fine. While I am using the designer in GroupLayout it works pretty well. However, when I run my RCP application I get the following error:

java.lang.NoClassDefFoundError: org/eclipse/swt/layout/grouplayout/GroupLayout
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Unknown

...

I see that swt-grouplayout.jar and baseline.jar were added to my project, but for some reason they aren't getting added to my classpath. I tried adding them manually but that yielded the same error. Strangely, there is nothing in my log file.

Any help would be greatly appreciated.

Thanks in advance.

Those JARs - needed for GL support in SWT - are added to your project and to your project's .classpath file.

If You are using them in the context of a plug-in (as in an RCP app), you need to add them to your plug-in manifest file so that they are found at runtime.

That fixed it thanks.
