I am trying to incorporate JBoss Rules into an existing RCP. I have tried to follow directions. First, I have installed the plugin and can recreate a rules project, and can run the demo rules project. My problem is adding this to my existing RCP. I have tried to follow information on the Wiki, so here are my .classpath and .project files, followed by the errors that are logged when I try to open a rules file. Sorry for the length of the post:

When I create a simple rule resource using the wizard, I get errors:

!ENTRY org.eclipse.ui.workbench 4 2 2007-06-02 17:54:21.688
