Yes, on the initial install, I used the included versions of both Java and Tomcat. I made multiple attempts to install and run, with the same rsult. Ive attempted setting max permissions on comeplete directory structure, just to eliminate any kind of permissions issue. On failing the binary install, I manually installed both java and tomcat, then used the WAR install - both java and tomcat seemed to operate ok independantly; however Im getting this error when I attempt to hit /jasperserver/ Preference is for Centos, but next step is to try a different distro. I guess just hoping someone else had encountered this and there wasa quick solution, or setup that maybe Id overlooked. thanks
