I fetched OpenGrok 1.3.4 from their download page[1] and followed the installation instructions [2] to setup the software on my system (FreeBSD 12.1-RELEASE).
I have tomcat8.5 installed and the default welcome page displays without any issues. I use Universal Ctags and I think other dependencies listed in OpenGrok web site have already been installed.
pkg install openjdk8 universal-ctags tomcat85 python36 py36-pip ctags
I can view http://localhost:8080/source, which displays error messages since the indexer was not run at this stage (this is expected as indicated in the installation instructions).
When I try to run the indexer, I am getting the error below and I think it is related to my Tomcat or OpenGrok settings rather than the system I am trying to install the software on. My experience with Java servlets or server pages is very limited hence I would appreciate any guidance.
