Open Source Document Management System | OpenKM

I am using openkm 5.1.7 on linux, firefox browser
I have moved my openkm(mysqldb) installation to a different server (ubuntu). It previously ran on centos.
I copied the whole jboss folder to the new server.
I am getting errors while logging in. Have attached the print screen:

You stopped jboss
copy jboss folder to new server ( same path )
backup database and restore to new server
and then start jboss in new server

And now appearing these error ? are you sure you've done it with same steps ?

Can you post the $JBOSS_HOME/server/default/server.log ? Please, zip it before attach.
