[CodeReviewer] ccollab_server won't start

So did some digging. CentOS install OpenJDK Runtime Environment (rhel-2.3.10.4.el6_4-i386). Did som googling on the error message. The command line uses  -Xmx1024m, I changed this to  -Xmx512m and the error in the terminal window does not appear, however the server does not start.  When I look at /opt/ccollab_server/error.log it contains the following:



java.lang.ClassNotFoundException: org.apache.catalina.startup.Catalina

So what I am missing?
