Error deploying war to tomcat6

[Alex Ditu]

Hello,

I'm using version 0.81-release.

Until now I've run bbb-web using: grails -Dserver.port=8888 run-war and it worked just fine. But now I want to deploy the war to tomcat6 server. I've done these steps:
grails war
sudo mv target/bigbluebutton-0.70dev.war /var/lib/tomcat6/webapps/bigbluebutton.war
sudo service tomcat6 restart

I've noticed that the .war is expanded to bigbluebutton folder. Then I get the following error in catalina.out:

INFO: Deploying web application archive bigbluebutton.war

Also, if I put back the original bigbluebutton.war to webapps and restart the server everything works fine.
Any hints?

Solved:

It looks like my tomcat was using java version 6, so I modified the startup script to use java version 7, and now it works.

Hi Alex,

Thanks for sharing how you got it working.
