> Is hibernate initialized via a <listener> in web.xml, or where?
I don't know exactly how it is initialized. I use spring annotation
configuration with a
javax.servlet.ServletContainerInitializer but I don't know, if hibernate gets
loaded immediately.
Looking at the call stack, it seems that it gets initialized by a
"ContextLoaderListener" in an event called
"contextInitialized" that gets passed a javax.servlet.ServletContextEvent.
So I would say yes, it gets initialized by a listener.

Thanks for the hint.

They are just in $CATALINA_BASE/lib and not bundled with the webapp.

This might be the cause - if resources get registered later to allow loading
the driver before.

Explicitly using
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
in context.xml to use tomcat dbcp doesn't change the behavior.

The full stacktrace gets truncated by my IDE, because it is very long (the
exception causes 3 other exceptions that get
printed with complete stacktrace).
I copied the thread dump at the statement directly after the exception got
thrown:

> Maybe you can try debugging, with a breakpoint in org.apache.naming.* classes?
I don't know where I should look. I started looking at the failing lookup()
statement.
org.apache.naming.java.javaURLContextFactory#getObjectInstance() calls
ContextBindings.isThreadBound() and
ContextBindings.isClassLoaderBound() - both return false.
In tomcat 8.0.0-RC10 ContextBindings.isThreadBound() returns true and the name
resolution succeeds.
Maybe this directs to the cause of the problem.

Christian
