Demo-Installation of Activiti failed

[posicore]

Hello,

followed the instructions concerning the demo setup in the activiti user guide. But when I open http://localhost:8080/activiti-explorer/ in the browser, I get a 404: The requested resource () is not available.

Here´s the content of the catalina.out. There occured several errors. Can anyone help me out please?

Platform is Mac OS X 10.5.8, JDK 1.6.0_26.

Regards,
Olaf

Hi,

Are you sure Java 6 is the default Java version? Can you check this by running java -version and javac -version?

Best regards,

[posicore]

Hi,

I checked the version and the output was Java 6 both times.

Regards,
Olaf

Where does JAVE_HOME point to?

[posicore]

The JAVA_HOME was not properly set.

Thanks a lot!
