Hello Omatzura
based on your suggestion i installed Soap 2-0beta and have encountered following error:

I have mailed the problem to jvmpi_eol@sun.com. hopeful to receive the reply soon..

Thank you

Hey Thanks buddy for the immediate response!!

let me verify this solution 

Step1: Created a new SOAP request
Step 2: Assign a keystore path along with password:  File->preference->SSLsetting
Step 3: Added the arguments
Step 4: Submit the request

The architecture has Datapower and so the xml message is not being digitally signed. On the datapower side, I am getting the error at the verification step - i can see this from the Datapower console

Also, in Soap UI, how can i ensure the digital signature is a part of the header information in the SOAP message.

Please suggest!

Thanks

Hi, Unable to pass the keystore information thro Datapower.
and i get the following warning msg in SoapUI log

Thu Nov 15 18:43:02 EST 2007:WARN:Missing matching Fault in wsdl for bindingOperation [MethodName]

So can i pass the certificates thro datapower using SoapUI?
