Hi,

I am unable to launch WMB 6.1 Toolkit due to the following Eclipse Error.
Quote:

!MESSAGE Exception launching the Eclipse Platform:
!STACK
java.lang.ClassNotFoundException: org.eclipse.core.runtime.adaptor.EclipseStarter
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)

at org.eclipse.core.launcher.Main.basicRun(Unknown Source)
at org.eclipse.core.launcher.Main.run(Unknown Source)
at org.eclipse.core.launcher.Main.main(Unknown Source)


I have other Websphere Software including WMQ installed in my desktop which is running without any Eclipse problem.

Do anybody has any experience of this kind of problem, please suggest me how could I overcome this eclipse issue?

Thanks,
Partha

I have deleted the metadata folder from my workspace and try to launch the toolkit, but I go the same error.
Please suggest some other work arounds if possible.

This is not an Eclipse issue.

This is either an installation issue or a configuration issue.

So if you have changed anything about the Toolkit after you installed it, then you made a configuration change that is wrong. If you did not change anything, then the installation was not correct.

The easiest way to start is to reinstall.
