Exception when trying to get ConnectionFactory

[sacauskis]

I have this simple program to use JMS. When it runs:
TopicConnectionFactory tcf = (TopicConnectionFactory) context.lookup("ConnectionFactory");

I get an exception:

Thanks for any help you can give.

Can you make sure you've got javassist.jar in your classpath? Please refere the documenattion where it describes the libraries you should have in your classpath,when sending messages from a plain JMS client

Cheers

[sacauskis]

Thanks, where is the documentation at?

[gaohoward]

Or you can have a look at one of the JBM examples. In its build.xml you can find what classpath it should use.
