Just a quick heads up if you are having issues when using the web_services_set_security function in LoadRunner.

The web_service_set_security function is used to add security tokens to subsequent soap and web service calls. When replaying one of my web service scripts that use the web_services_security function I keep getting an “Action Mismatch” error.

Cause for the Action Mismatch Error

The script is using the web_services_set_security to create a message signature. But LoadRunner is sending the whole message with a Time Stamp, Body and Header.

This behavior is killing my application service because it only expects to receive the Body to be signed — not the whole message. Because of this behavior I keep getting a LR “Action Mismatch” error. After looking around in HP KB I found out this issue is a known product defect.

How to Resolve this LoadRunner Error

• First grab the file DeleteSoapHeaders.zip from my download section.
  
• Copy the DeleteSoapHeaders.dll to your Load Runners’s bin folder
  

• Next to configure the deleting headers choose either Method 1 Script Level or Method 2 Step Level below.
  

Method 1 Script Level

Making this change will send all the WSC’s in the script without any header in the soap envelope.

• Navigate to your LoadRunner script’s directory and open the default.cfg file with a file editor like Notepad or Notepad++
  

  
  

• Add a section called UserHandler to the very end of the default file. The exact section to copy is:
  

• Save the file and run your script. The
  
  element should no longer appear in the soap envelope.

Method 2 Step Level

Making this change will only be applied to a specific step.

• Add the step that you want to send without the headers to the script
  
• Add the following lines of code to your step right before the BEGIN_ARGUMENTS element:
  

That should work

Let it rip – you should be good to go now. Hope it helps you.
