Re: NullPointerException encountered when I try to connect Scarab after installed successfully

Hi;

I know it has been quite some time since you have published this post, 
if this issue still occurs -> please stop your Tomcat, delete the 
log-file, restart the Tomcat and attach the new generated log-file to 
your post. I hope i can bring some new facts to light soon.

Regards
Marc
