TemplateNotFound Exception in Apache Ofbiz in Debug mode from Eclipse (Ubuntu) - eclipse

Question

I configure apache ofbiz in debug mode using the second method titled Debugging (or running) OFBiz inside Eclipse from this guide. I have repeated the same procedure on windows and Ubuntu. In windows, ofbiz runs fine without problems and I can use it from browser on https://localhost:8443/ordermgr/control/main. But when I follow the same guide and try to run ofbiz from Ubuntu (16.0.4), I get the TemplateNotfound exception which is thrown from RequestHandler.java at line 989. Here is the stack trace
Communication error with the client while processing the request: /webtools/control/ServiceList

Any ideas why I get this error in Ubuntu?

Answer 1

I am not sure what exactly the problem was but I was opening the ofbiz project from a different location than eclipse workspace and containing directory name was different than project name. I did the following to get it working
Deleted the project from eclipse
Moved the project directory to workspace
Renamed the project directory to match project name (ofbiz)
Opened it from eclipse
Followed the guide to debug/run as mentioned in my question
and all was suddenly working
