exception on JaxRpc invoke: unknown prefix in QName literal: null

This small post is all about to discuss an error I got during run time of a BPEL process.
There may be a lot more reasons to see this error, but I would like to discuss one instance where I see this error.

If you see error, obscurely it says there is a problem in invoking other service.In my case my BPEL process bpel.xml  is referring to wrong url.

For example:

My bpel.xml is referring to

 <partnerLinkBinding name="BPELProcess1">
            wsdlLocation">http://host.domain.com:7778/orabpel/default/BPELProcess1/BPELProcess1?wsdl
 partnerLinkBinding>


What I observe here is connection could not reach  host.domain.com  and that caused this error.
When I replace  wsdl location with another wsdl for same process and different host, then it got executed.
There may be firewall which is restricting access to the box. So please be careful..
