Hi,

I try recently the graphic SWT / JFace library.
I use the JFace TreeViewer as it is described in this IBM's article:
http://www-106.ibm.com/developerworks/opensource/library/os-ecgui1/

I have two problems :

1. they give 5 jar files to include, but I find only 4 files. Indeed the
directory ..../eclipse/plugins/org.eclipse.runtime_2.1.0 does not exist!
Has anybody this directory?

2. The missing .jar file does not prevent me from compiling their TreeViewer
example, but during the execution, I obtain the following error:

java.lang.NoClassDefFoundError:

Exception in thread "main"

Nevertheless, my program is exactly written like in the IBM's example, an
idee? I don't find the class DelegatingURLClassLoader !!!

Thanks
