Hi All,

I think there is a small issue with the JBPM4.4 Tomcat installation. I just downloaded the latest JBPM version 4.4 and tried to install it by using the ant target "demo.setup.tomcat". The target tries to download apache tomcat 6.0.26, but it seems that this version is no longer available?! I checked the apache tomcat download site and recognized the current version is 6.0.29... So I switched the tomcat version property to that version and everything worked fine until I tried to stop tomcat after “demo.setup.tomcat” by calling the ant target " demo.teardown.tomcat" (see logging snippet):

So far not really good, but working... After starting and stopping tomcat (and hsqldb) several times by the corresponding ant target, the JBPM-Console refused any attempt to login by throwing the following error (see stack trace):

Does anybody know if Tomcat 6.0.29 is working properly with jBPM 4.4?

Best wishes,
