The full console output was too large to paste here.

What am I doing wrong? The JDBC JAR is there, it’s in the script, and MySql is configured.

Oh, I’m using OpenJDK 6 because there’s a problem with JDK 7 and James, although I expect that only applies if you’re using the JDK and not just the JRE as I am.

I can see that this isn’t the first time around on this question, perhaps.

The conf/lib/*.jar loading in beta4 is buggy.

Can you edit the conf/wrapper.conf and change 
'wrapper.java.classpath...=../conf/lib' to 
'wrapper.java.classpath...=../conf/lib/*' (add a /* after lib).

Thx, Eric

    although I need to test it out a bit.
