I have a document that explains this here - to get the Castor ObjectFactory and Tyrex ObjectFactory classes you will need to download the castor-taglib.jar and put it on your project classpath.

Here is a document that describes how I was able to set-up castor under Tomcat using JNDI.
I hope it helps.
Thanks, Neil.

Hi,
I am trying to configure castor 0.9.4 thru JNDI using the DBCP pooling mechanism. My platform is Tomcat 4.0.3, and MySQL 3.23.49.
I've found one of your messages in Castor-Dev list archive (Friday, November 01, 2002 10:10 AM).
I have the same pb you seemed to have then.
You said "I got it to work" , but you don't say how .
Could you give me the right code for web.xml, server.xml , database.xml and the getJDO method ?
Thanks for your help.
Sylvie.

Is "jdo" a context that's automatically created for you by Tomcat?
I don't know much about Tomcat, and it's JNDI namespacing, but in Resin, in order to provide the jdo/whatever naming, I had to create a startup servlet that would create the "jdo" subcontext like so:
InitialContext initCtx = ( new InitialContext()).lookup(
"java:comp/env" ); Context ctx = initCtx.createSubcontext( "jdo" ); ctx.bind( "whatever", jdo )
there's some error checking in there, too, to check if that subcontext exists ( so multiple startup servlets could be provided ), but that's the basic gist of it.

Hello:
I am tryng to configure castor 0.9.4 thru JNDI using the JBCP pooling mechanism. My platform is Tomcat 4.0.6, Apache 2.0.43, and MySQL 3.23.53a on RedHat Linux 8.0.
When I try to load the JDO object from the context, here is the error I get:
