While im recording a site response code loading fully and while replaying that complete response code is not loading properly. so, how can i do overcome this
After recording, correlation should be done before executing the load test:

hope this will help.

I am new into Jmeter and trying to do my first load test, When I get my data from website it is always come in .txt form and when this data I try to run my test it fails,
It's hard to say what is wrong without seeing the "Sampler result" tab screenshot for at least one failed sampler.
Going forward consider providing as much information as you can, i.e.:
Screenshot of the HTTP Request sampler
Screenshot of the View Results Tree listener demonstrating Sampler result, request data and headers and response data
At least relevant parts of the jmeter.log file, better with the debug logging for the test elements involved enabled
I have a Jmeter script for an application for which i get pop up error message intermittently. Where as in jmeter we only come to know that flow got terminated by some failure.But we wont come to know the occurrence of Error pop -up message.
My requirement is if we encounter pop up error i want to write to an external file saying that ,the current page got failed due to pop-up error message.
If we can write the error message it's really great. I'm as of now not getting idea to achieve this.
Please can anyone help me in this. or can provide any hint to do R&D.
Thankyou in advance.
Updated the question with screen shot of error message.
As per JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
Looking into your screenshot, it is a form of JavaScript popup, most likely window.alert so there is no way to detect it via JMeter.
You can add i.e. Response Assertion to your test in order to introduce some pass/fail criteria, i.e. if you were in the middle of some transaction when the error occurred it should not finish successfully resulting in missing expected entry in the web page (or database), so you can conditionally fail relevant sampler(s) in this case. See How to Use JMeter Assertions in Three Easy Steps to learn more about the concept.
Alternatively you can use WebDriver Sampler plugin which provides JMeter integration with Selenium browser automation framework which drives a real browser, so you will be able to capture this popups and record the page titles/take screenshots, check out IsAlertPresent() class for more information.
you must get this error response in your jmeter request response.simple answer.Have a regex to extract.
I can't close an alert with Jmeter on my website.
Jmeter return me the following message : "500/unexpected alert open".
I tried a lot of methods and I investigated a lot on internet, but I haven't found a solution :(
please, help...
JMeter is not a browser, as such it doesn't interpret client javascript as Selenium does it.
So you need to understand what Javascript does in terms of request(s) going to server and reproduce this with HTTP Request
Finally I have found a solution to my problem with the following command :
WDS.browser.executeScript('window.onbeforeunload = null;')
I want to load test my web site.
I can extract all http requests from the site and put it on J meter.
But the page have alot more things(like ajax calls)
How can i load test my site (find complete page load time)
I'd go the route of capturing the AJAX calls as past of your script - you have two options:
The JMeter proxy:
http://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.pdf
BlazeMeter's JMeter chrome extension:
https://chrome.google.com/webstore/detail/blazemeter-the-load-testi/mbopgmdnpcbohhpnfglgohlbhfongabi/details?hl=en
Jmeter is Server side load testing tool and though client is using ajax still http request will be sent to server which will be recorded/scripted in jmeter and thus load testing can be carried out.

I recently recorded a test script in Jmeter intended for use as a load test script (using this handy set of instructions. The recording itself worked great and I even figured out how to grab and parametrize the session ids and timestamps. However, if I run the recorded steps just as they were recorded some of them don't work -- they generate "500--Server encountered and internal error ...nested exception is java.lang.NullPointerException" The failing steps are all Ajax calls that populate sidebar elements. If I copy the request GET call (Request tab, ViewResultsTree) and paste it into a browser I get the exact same error. Do I need to record my script differently, or hand-code the ajax calls? Other, earlier steps work correctly and send the expected POST data, so it isn't the application under test or forgotten proxy settings. Currently running against Firefox 3.6.10
Any suggestions on how I can debug this would be greatly appreciated.
The first thing I'd do is determine if the java.lang.NullPointerException is happening on the client side (JMeter) or on your server. If it is happening in JMeter, than something is terribly wrong with either your script or with JMeter.
But assuming that the error is encountered on your server, then looking into the cause of the exception may shed light on what is wrong with the request issued by JMeter. Do you have access to the code where the exception is thrown?
I would also recommend comparing the request in the recording with the request that generated the error. You may need to determine which parts of the request are session-specific and ensure those fields are populated correctly.
It sounds like Jmeter isn't executing the AJAX calls, and this can be fine depending on your site. Can you simply do an HTTP request to get the pages the AJAX calls populate?
I would recommend reading this post, as it looks pretty good.
I've seen that situation caused by a few things:
a page is required to load and be cached BEFORE making the failing request;
the failing page needs to automatically redirected to work properly;
the failing page has sub-requests JMeter failed to record. Devs can help with this.
Hope this helps.
