Webservice request working in SOAP UI, but failing in Jmeter

Question

I have a web service, which is working perfectly with SOAP UI, but throwing 500 error when tried to from JMETER 2.1.3.I am using SOAP/XML RPC Request, another open endpoint(http://www.webservicex.net/whois.asmx?WSDL) with jmeter is working perfectly fine. Is there any setup to be done with my service to get it invoked from JMETER?

SOAP/XML RPC Request:

Use a sniffer tool like Wireshark to capture requests send by SoapUI and JMeter and determine what is the difference.

My expectation is that you're missing a HTTP Header, maybe SOAPAction or Authorization or something like that. Headers can be manipulated using HTTP Header Manager
