          You'll have to use your debugger.

            I have the same problem. It occurs already at startup when loading an application.

              Actually, this happened after I installed the seam booking example according to the Wiki article found at http://wiki.jboss.org/wiki/Wiki.jsp?page=EclipseSeamProject.

              When deploying it and starting JBoss, I get:

                And so you'll need to "use your debugger" too. :)

                  Ok, I fixed it for me:
                  in components.xml were some values like '@something@'; when I replaced those with real values ('true', ...), it started up just fine.

                    Well that's just groovy, what exactly are legitimate values for this file or where do I go to figure out some for myself?
