No hints found in logs, no error megssage. In one world it's "mysterious". Hi! I have two identical virtual machines with Jasperserver 4.5, tomcat 7 and jdk1.7.0_02 on debian 6. In one of them I can upload the jrxml file but in the other one the same problem persist. Someone comes up with something to help? Thanks in advance!
