Subject Re: Locally Reffered EJB by Servlet Problem
Date Mon, 17 Jul 2006 05:56:36 GMT
Hi Derk,

I added the ejb-local-ref element in to the web.xml. But still it gives 
the same error. Don't know whether problem due to a configuration files 
I have attached here or not. Please help.

Thanks,
Lasantha
