OpenSAML user discussion

Hi,

 I am trying to run the test class SOAPBindingTest.java and got the following 
exception:
<Status><StatusCode 
Value="Responder"></StatusCode><StatusMessage>SAMLSOAPBinding.send() caught 
an I/O exception (wrapped: shib2.internet2.edu)</StatusMessage></Status>E
Time: 2.154
There was 1 error:
1) 
testSOAPBinding(org.opensaml.SOAPBindingTest)java.net.UnknownHostException: 
shib2.internet2.edu
        at org.opensaml.SAMLSOAPBinding.send(SAMLSOAPBinding.java:272)

FAILURES!!!
Tests run: 1,  Failures: 0,  Errors: 1

Has anyone encountered this type of any error?

I am using IBM Websphere Studio Developer as my workspace and jdk1.4 as the 
jre. 

Also does anyone know where I can find sample xml for SAMLRequest, 
SAMLResponse and SAMLAssertion.

Thanks in Advance.
