When I test my application with JMeter on weblogic server for one user I get:
Error 500--Internal Server Error From RFC 2068 Hypertext Transfer
Protocol -- HTTP/1.1:
10.5.1 500 Internal Server Error
The server encountered an unexpected condition which prevented it from fulfilling the request.
This error present only on one page which is in the middle of the test application. I have Cookie Manager to get cookie id from response and cached all url parameter which is changing dynamically.
Any idea?
I faced the same problem "Internal Server Error" i.e, Response code 500. I cleared the results and added HTTP Cookie Manager to the thread and executed successfully the Test Plan.
Here you, my Result without HTTP Cookie Manager

Fingers-cross
Internal Server Error (500) means there is something wrong with your server code - probably an uncaught exception. Try to debug your server code when it is being accessed by JMeter.
My script is only getting executed for recorded data and not parameterized one, though in Tree Listener ->Request-> HTTP is displaying parameterized data from CSV file, but post execution record are getting updated only for recorded data, is it because scenario is based on ajax requests. Please do let me know in case elaboration required.

I am getting "Response code 500 - Internal Server Error" for a performance test run in Apache J-Meter 4.0 for a recording of a simple test done over VPN. I am new to this tool and want to know how I can investigate this. As reference, I am mentioning the sampler result error that I am getting.

Add HTTP Cookie Manager to your test plan
Detect all dynamic parameters and perform correlation
Also looking into AWSALB cookie my expectation is that your application under test "hides" behind Amazon Elastic Load Balancer so make sure to add DNS Cache Manager to your Test Plan.
If you still experience problems you can try catching the requests which is being sent by JMeter and by the real browser using a sniffer tool like Wireshark or Fiddler - the requests should be exactly the same (apart from dynamic parameters mentioned in point 2).
I am using JMeter 4.0 for recording & running performance tests. I am also fairly new to this tool and for the 1st time, I'm getting Error 400 Bad request for which all the tests are failing. I am recording a website through VPN & trying it to run the test the same way as I did before.
Can you please help me with this. I can provide additional screenshots and details as & when you say required.

As per 400 Bad Request description:
The HyperText Transfer Protocol (HTTP) 400 Bad Request response status code indicates that the server could not understand the request due to invalid syntax.
The client should not repeat this request without modification.
So most probably you're sending malformed requests which server doesn't understand.
The only troubleshooting technique I can think of is recording requests which real browser sends using a sniffer tool like Fiddler or Wireshark and comparing them to what JMeter sends. The requests should be the same (apart from dynamic data which has to be correlated)
As soon as you amend your JMeter test plan to 100% match requests which are being sent by the real browser it should start working. Don't forget about Cookies and Headers.
So I am trying to test the file upload function of this website: http://the-v.net/en/vtube/upload-video through JMETER but to be successful, the user has to be logged in through this form: http://the-v.net/login, Now, I think this is a parameter-based authentication which could be solved by defining a valid username and password in the HTTP Authorization Manager config element, but even doing so I keep getting this error:

I would suggest you record the upload in the browser and look in View Results Tree the headers/ coookies that are transmitted.
You can use File > Template. > Recording
Read:
http://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.html
You are most probably missing:
A header
A cookie
A parameter
You need to be logged in in order to be able to upload anything. HTTP Authorization Manager won't help as it is designed to deal with protocol level authentication and you need cookie-based one.
Add HTTP Cookie Manager to your Test Plan
Pay attention to form_build_id dynamic parameter you need to pass along with credentials during login request
So your test plan should look like:
1st HTTP Request - open login page
Post-Processor (i.e. CSS/JQuery Extractor to fetch form_build_id
2nd HTTP Request - perform login - provide credentials and the form_build_id from the previous step. You will also need to pass form_id parameter with the value of MYFORM_form
3rd HTTP Request - perform the upload.

Depending on authentication information your application expects you can work it around in several ways:
Basic HTTP (looks like modal pop-up window when you're trying to open protected page). To bypass it add HTTP Authorization Manager to your Test Plan and provide credentials there. See How to Use HTTP Basic Authentication in JMeter article for details.
Missing or incorrect parameter. Some applications use dynamic parameters for security purposes and if you recorded it - it is hard-coded and cannot be replayed successfully. Try recording your application 2 times and inspect request details for differences. If there are any - work them around using JSON Path PostProcessor
I'm new to jMeter testing. I want to test the field update on UI. So When I run my test I'm getting the CSRF validation error. How can I resolve this. My test plan looks as,

Why do we get CSRF validation error and how to resolve it.
CSRF stands for Cross-site request forgery and you're getting CSRF Validation error due to missing mandatory dynamic request parameter, usually a Cookie or a Header.
I would suggest executing your scenario in i.e. Firefox Browser with HttpFox or FireBug extension enabled and inspect request details. CSRF token usually comes as a cookie in server's response and needs to be passed as a header or request parameter. So it is similar to usual correlation. So the flow should look as follows:
First HTTP Request: open first page
Extract CSRF token from response via one of the following Post Processors
Regular Expression Extractor
XPath Extractor
CSS/JQuery Extractor
Second HTTP Request: open second page (CSRF-protected). Add the token, extracted in step 2 to one of the following:
HTTP Request Parameter
HTTP Header Manager
HTTP Cookie Manager
Depending on where your server expects the token to live.
For the future, looking at your "localhost" server name - don't run JMeter performance tests on the same machine where application lives.
