While installing D6 Content Server on Linux I got a
NullPointerException right at the point when it would try to install Weblogic for the Java Method Server. I was unable to locate any helpful information from the logs.
Then I found a thread on Powerlink Support Forums, entitled “Error Installing D6 Content Server”. While it didn’t give a direct solution, one of the posts indicated that it is probably a permissions issue. I did a quick check and sure enough
/opt/dctm has owned by root while the install owner was dmadmin. Changing ownership of the installation path to
dmadmin fixed the problem.
