Using LoadRunner to capture SOAP requests generated using soapUI application

Problem:
How to capture soapUI request(s) in LoadRunner.

Assumption:
1: A SOAP request has already been created in soapUI. I am using Metric Weight Unit Convertor WSDL from webserviceX for this problem.

Solution:
1: Select an Web HTTP/HTML protocol in LoadRunner.

2: In Start Recording window, input the following options:
Application type: Win32 Applications
Program to record: "...\HP\LoadRunner\bin\micexec.exe" -->micexec.exe path
Program arguments: "...\soapUI-4.0.0.exe" -->soapUI path

3: Click OK button. This launches the soapUI application.

4: Run the SOAP request in soapUI. You will notice that LoadRunner is now capturing the soapUI traffic.

5: Stop the LoadRunner recording, once soapUI has finished submitting the request. You will notice that the same request created in soapUI has been captured in LoadRunner.

6: Replay the script in the LoadRunner and you will notice that the correct response is returned.

NOTE:
You might get "The JVM could not be started. The maximum heap size (-Xmx) might be too large or an antivirus or firewall tool could block the execution" error message.

You can fix this issue by updating the -Xmx value in the soapUI-4.0.0.vmoptions file. Reduce the size JVM Xmx value. In my case, I reduced it from 1200 to 512. This fixed the issue and I was able to record the script. You might also get OutOfMemory issue when launching soapUI using LoadRunner. This is because the maximum heap size set in soapUI is less than the memory required by soapUI to successfully launch. Increase the heap size to what the soapUI application requires or remove the unnecessary projects.
