F5 invoke a java component and a webservice

Hi, i am new to F5, here is my requirement.

From the HTTP requests on my F5 LTM I need to capture all SSN (of the form SSN=123456789) , invoke a Webservice on another machine passing the actual SSN. Replace the SSN with the response from the webservice and send the request to the designated server

if java is not possible , what other languages can be used to call a webservice . Any help would be a great help. How can I enable Java on the LTM and modify incoming request with java ?
