Logging those hidden stack traces

Question

Hi,

I'm develping a GWT application with Ebean. When I deploy it to my Tomcat 6 server, I get an Exception related to Ebean, but I don't know what it is. The stack trace is truncated, and shows the message "... 28 more". How can I see those 28 more?

I also use log4j 1.2.

Thanks in advanced. This is a copy of the output.

Answer 1

NoClassDefFoundError means that the JVM couldn't find the class class com.avaje.ebean.Ebean and, hence, it couldn't initialize it.

Download the full jar ebean-x.jar here and add it to the project CLASSPATH.
