It was tomcat 3.1. Thanks for the explanation.

If you look at the code for the Jdk12Interceptor (it comes with the binary
version of tomcat) you will see that all it really does is set
the context class loader for every request. It applies to jdk 1.2 and above.
This is because the Thread.setContextClassLoader() was
added to the jdk for 1.2. The reason you need it with jboss access is that
the
jndi code uses Thread.getContextClassLoader to load the
jndi implementation. If you place the jndi impl class jar in your
web-inf/lib
directory then then classloader for this web app needs to be
the context classloader. Thus setting it for every request is required
because
you don't know which thread is going to be used to call
your servlet/jsp.
By the way the Jdk12Interceptor was only introduced for Tomcat 3.2 and
above. I
rememeber running tomcat 3.1 standalone with
jboss without needing anything like this. I don't know for sure but probably
a
different classloader architecture was beeing used.
