[news.eclipse.technology] Problems with runtime workbench and jdt core

["Vijay Ganesan" <vijay@xxxxxxxxxxxxxx>]

I am building a plugin that uses the JDT Core APIs. I can build fine ( i
have ECLIPSE_HOME/plugins/org.eclipse.jdt.core_2.1.1/jdtcore.jar in the
classpath).
However when I launch the runtime workbench I get the following error:

java.lang.NoClassDefFoundError: org/eclipse/jdt/core/JavaCore

How do I find out what classpath is used by the runtime workbench? I tried
choosing "Choose plugins and fragments to launch from list" and made sure
the org.eclipse.jdtcore was checked. But I still have this problem.

The second issue is - when I make a code change, I am forced to shutdown the
runtime workbench and re-launch it to detect the new code changes. I thought
I saw a demo by one of the Eclipse team leads recently where he did not have
to restart the workbench after some code changes. Is this achieved through
some setting in the run configuration?

thanks
