Greetings,

I have created and deployed two web applications(say webapp1, webapp2) that 
generates SOAP message to access a remote web service. We are using Jboss 
5.0.0.GA.
Both these applications run fine, if I run then individually. That is, when I 
start the jboss server and access webapp1 first. Then, I do not have any 
trouble with webapp1. Now, when I access webapp2, I get the error message 
listed below.

I get the same error message, when I start the jboss server and access webapp2 
for the first and try to access webapp1 second.

So, if I am testing webapp1 and want to test webapp2, I have to restart the 
jboss server and access webapp2 as soon as the server starts up.

This is the code I have in webapp1
