Hi,

I am currently working on a project involving Activiti and before starting to get my own projects into runtime I wanted to test out the Demo-Setup. Unfortunately I encountered the same error as described in this topic and have not been able to find a solution yet.

Help would be really appreciated.

Kind Regards
Matthias

Hi,

Did you try and stop the Tomcat server and start it up again?
Can you see a stacktrace in the Tomcat log?

Best regards,

Hi,

I looked up the logs files of the Tomcat and will post the (shortened) output:

All I did was moving via console to a fresh downloaded+extracted activiti 5.8 setup folder and typed "ant demo.start".
But I should add, that i needed to download the apache tomcat 6.0.32 manually and put it in the downloads folder activiti uses, because I work behind a proxy and the ant build failed downloading it.

Note: I'm working on Windows7 and read about some other problems with Activiti and Windows7 so I mention this, too

Kind Regards,
Matthias

Strange, because I don't see any logging that shows that the Activiti Explorer is started.
I know the Activiti setup script changes the Tomcat distribution a bit. Maybe this went wrong in your setup.
But still, the Activiti Explorer should work. Were you able to start the H2 database?
Which Java version are you running?

Best regards,

Hi again,

good hint with the H2 database. I was able to connect and browse it and tried to access the activiti-explorer again afterwards. This way round it started and I was able to log in. But then I had the same problems as referred to in this topic: http://forums.activiti.org/en/viewtopic.php?t=2339.
Fortunately there was a solution posted and I can finally get back to work

Hopefully this was the last strange error.

Kind Regards,
Matthias
