I have just upgraded to JBoss IDE 1.5, from JBoss IDE 1.5RC2, and now I cannot open my persistence.xml file in my EJB 3.0 project. I did start up Eclipse with the -clean option before seeing the problem, so it might be related to that, but I don't know. I get an exception as follows:
This exception is certainly not the problem, as it is just getting this exception trying to find an exception class, that isn't there, and it wasn't ever there.
Any help would be greatly appreciated.
I removed all JBoss IDE plugins, and removed the WTP stuff as well, and then reinstalled the JBoss IDE 1.5 through the update site, and now everything is working just fine.
