I downloaded latest svn version of pentaho(trunk), built tomcat-mysql war, deployed it on tomcat and it's not working. But when build war from pentaho_j2ee_deployments-1.6.0-RC1.782(from sourceforge) it works fine. Setting are same for both versions.

Windows XP
MySQL 5.0
Ant 1.6.5
Tomcat 5.5
jdk 1.5.0_12

Can anyone tell me why this is happening.
Here is log:
