Take a look at the attached screenshot and compare that to your settings.

The Regular Expression Extractor I have (called \"Flow Execution Key Extractor\") is a child of an HTTP Sampler (called SimpleController) and is located immediately after the first request that comes back with a flowExecutionKey. As per the JMeter documentation:

\"A Regular Expression Extractor will execute after each Sample request in its scope, applying the regular expression, extracting the requested values, generate the template string, and store the result into the given variable name\"

Beyond that there are several potential issues you might be having:

1) Are you placing the Regular Expression Extractor for the flow execution key after a request that contains what the regular expression is looking for?

2) Ensure you JSP page contains what the regular expression is looking for. In other words you must have a hidden variable such as \". If not you will need to adjust the regular expression to match your page.

3) Use a \"Save Response\" post processor to save the HTML returned from JMeter and check it contains what the regular expression is trying to match on.

Good luck.

(Sorry, put my previous post seemed to fail).
Any idea why I get "Exception:Badly formatted flow execution key '${flowExecutionKey}'" when I use a ${flowExecutionKey} in a subsequent HTTP Request Element (a POST request)?

Hi David, I've attached a screenshot as well as the content of the JMeter settings file to the message above.

Hi Rossen,

Any chance you could give a screen shot of your Test Plan in the JMeter GUI, I would like to see exactly where you place the Regular Expression Extractor and HTTP Cookie Manager in relation to the other elements.

Thanks for the article though, I know a couple people who were trying similar things.

[…] Here is an article describing how to load test Spring WebFlow with JMeter. Some guys at work has been struggling with the same stuff in Mercury LoadRunner. They did a lot of http header debugging with Fiddler and got it running. […]
