Getting error while running the jmeter script with Ajax Request

Question

Getting this error. I am using the 3rd method from https://blazemeter.com/blog/how-load-test-ajaxxhr-enabled-sites-jmeter I have added the executable file in blazemeter-ajax-sampler-1.0-SNAPSHOT in lib/Ext What should i do to work it properly. Can I work with it without using blazemeter Again I checked with Listner View Tree and Found as in fig.

I am using Example Sampler to handle ajax requests. I have added one get method, url and value. I want to parameterise some string in the url. If I run the script without parameterising the string in the url it works. But it fails when I parameterised it. Can you please help? Please let me know if you need more information.

How to pass values(format) for Post method??

Also wanted to know how to add values In example sampler??

Answer 1

The mentioned sampler isn't a real AJAX plugin, you can use it as a reference for building your own sampler.

In order to see the request details you need to do the following changes in source code:

• in AJAXRequest.java change SampleResult to HTTPSampleResult
• use setRequestHeaders and setQueryString methods to store headers and body correspondingly
• the sampler is a "skeleton" so if you need it to be Cookie-, Cache-, Proxy-, etc. -aware you need to add this logic as well.

If it is ok for you to use the sampler in its current state - you can find request details in jmeter.log file
