[platform-dev] Migrating 2.1 Plugin to 3.0
Title: Migrating 2.1 Plugin to 3.0

Eclipse-Dev,

        I have a plugin from BEA that is 2.1 compliant and when I run it in 3.0, I get errors.  I understand that there were API/Architecture changes from 2.1 to 3.0 but this shouldn't be a big deal to migrate so I'm asking here.  Here is the error I get:

!ENTRY org.eclipse.core.runtime 4 2 Jun 29, 2004 13:44:15.790

!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.core.runtime".

I am trying to use 'org.eclipse.jdt.internal.debug.ui.launcher.ComboFieldEditor' and I just need to know how to update this code to be 3.0 compliant.  Thanks, Jeremy
