RE: Canï¿½t get J2 running

What version of the JDK are you running? I believe that Ate or Serge found that there is a bug in the classloader in JDK1.4.2_01 and earlier. Upgrading to the latest JDK (1.4.2_05) took care of the issue I believe.

Hallo,
fresh CVS-checkout, Maven RC3, allClean allBuld --> works fine
maven quickStart --> works fine
I'm having problems running J2 again after initial deployment.
If I stop Tomcat and start again I'm presented with the following stack
trace (in jetspeed.log):
