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.
Hi,
This is a very helpful website. Can you help in how to script the Soap request which is parsing the data in CDATA? Load Runner is not recognizing the CDATA part.

Suman » Hi Suman – I’m not sure I would need more info. Are you getting this error? What are you trying to do?
Hi !
I’m getting an error message when replying my script after certificate is added. The thing is that certificate “ID VALUE” contains an ampersand ( & ) character. Could this be causing the issue, how can I fix this?
xxx.c(35): Error: InvokeMethod failure: An error occurred while parsing EntityName. Line 1, position 148..
xxx.c(35): Error: ExtractResultArg failure: Object reference not set to an instance of an object..
xxx.c(35): Error: Web service call “xxx” execution failed
EPT » Not sure — do you get more info when you run with extended logs turned on?
Hey Joe,
Thanks for sharing this invaluable information with us..it is indeed really helpful. I am currently running a web service script but keep getting the HTTP 401 error. I turned on the extended logs and it shows an invalid session or session ID expired. My question is that how should i fix this issue as there are no cookies involved and i have tried the web_set_user and web_set_security function but nothing seems to be working. Thanks for your help,
rahul » Hi Rahul –does trying either of the following help:
1. Check Run-Time Settings–>Internet Protocol–>Preferences–>WinInet Replay instead of Socket (Windows Only).
The WinINet functions support server and proxy authentication for http sessions.
2. Â Go to:
– Run-Time Settings–>Internet Protocol–>Preferences–>Options.
– Under “Authentication” section, change “Enable Integrated Authentication” to “Yes”.
In this case, LoadRunner will use the username and password of the machine’s user to authenticate the session.Â

Hi Joe,

Looking forward for your help.
Hi Joe,
from where can i download the below mentioned file.
I am encountring error as “Error:ExtractResultArg failure: Object reference not set to an instance of an object” while doing a webservice scripting using a WSDL Url
First grab the file DeleteSoapHeaders.zip from my download section
Hi Sravya – I re-added the file to my download section: https://testguild.com/downloads/ can you try again?
Hi are you able to bring up the WSDL in a browser with out using any tool? Is the WSDL from a live system or are you using a local copy of it?
It is always recommended to consume the WSDL from a live system (in any environment) but otherwise it is important to copy all dependent files and edit the WSDL (and files) to resolve references.“
