I have Googled everywhere and read some weird answers: http://community.jaspersoft.com/questions/825605/problem-updating-jasperserver-50-55 I am running as root, so I fail to see how not having write privs to 'tmp' is an issue. I have read of possible missing dependencies, /etc/host not having the right mappings, etc. None of these worked, nor made any sense. The identical error I am getting is in the first message by OP of the linked article above. I do not know how to reolve this issue and it's frustrating me to no end. Why are the beans throwing exceptions? Is there a missing mapping in the XML files or something???
