Can you please share the error logs from file named like "sr.<date>.part.0.log"
Log file is a good idea.
BTW, why did you install it as root? SmartReporting is just a tomcat application and is very easy to install as nonroot. This would allow you to exclude all possible permission problems at the file level.
If I had to guess, I would guess a credential problem. The log file should give us some clarity.
