BonitaBPMCommunity 6.4.2, Ubuntu 64bit: Tomcat not starting

Hello,
I have downloaded BonitaBPMCommunity-6.4.2-x86_64.run; made BonitaBPMCommunity-6.4.2-x86_64.run executable; run in a terminal by ./BonitaBPMCommunity-6.4.2-x86_64.run. Installation (English/English) says: everything fine, want to start Bonita? I said yes. I had choosen all defaults (e.g. installation folder).
The Bonita Studio (?) starts, I can import a downloaded BPMN (os_procurement-3.0.bos) but after a while there is an error message:

‘Starting Tomcat v7.0 Server at localhost’ has encountered a problem
Server Tomcat v7.0 Server at localhost was unable to start within 300 seconds. If the server requires more time, try increasing the timeout in the server editor.

  • So what does this mean?
  • Do I need Tomcat?
  • Can I use without Tomcat?
  • What actions do I have to take to get things running correct?

Additional Informations:
BonitaBPMCommunity 6.4.2
Ubuntu 14.04 LTS
Java (output from sudo update-alternatives --config java)

Hi,

Do you have a Tomcat running in parallel? or another software which is occupying the port 8080?

Regards,

Hello Aurelien,
I looked into the process list for “Tomcat”, but nothing in there.
I looked to the listening ports (netstat -l) for “:8080”, but nothing there.
Seems, that this should all be fine.
Thanks, Tom
