Getting error “the request was rejected because no multipart boundary was found” while uploading the file in Jmeter

I have tried to upload the file in jmeter:

Please find below mentioned details which i passed in request,

Http reuest:

POST: http:${server_name}/attachment

1.File Path : D:\localdrive\test_docs\images.jpg 2.Parameter Name:images.jpg 3.MIME Type:image/jpg

Http Header :

1.Accept :  / ,
2.Content-Type :    multipart/form-data

Response Data :

 {"response":"the request was rejected because no multipart boundary was found"}

could anyone please share the solution on the same .

Got it !!!

Make sure that below parameter should be mentioned in HTTP request.

Implementation should be HttpClient3.1 or Java (Don't keep it blank)
Content encoding :UTF-8
"Use multipart/form-data for Post" in HTTP sample should be checked.
In HTTP header (Content-Type : multipart/form-data)
for Parameter-name & MIME-type e.g. In browser enter F12 & hit the request , refer the content in Network tab : Inside Param u will get request param for example if param is : HTML contains= Content-Disposition: form-data; name="file"; filename="images.jpg" Content-Type: image/jpeg

Then Parameter-name :file & MIME-type :image/jpeg should be like this.

& now its work fine ,That's a great relief for me !!!

also thanks Anders for ur answer.

HTML contains= Content-Disposition: form-data; name="file"; filename="images.jpg" Content-Type: image/jpeg So i have set = Parameter-name :file MIME-type :image/jpeg ; In sample request i have already checked "Use multipart/form-data for Post" which i have not mentioned early.

Then also its not work ... anything else which i missed here

There is a checkbox inside the sampler which uploads the file that says "Use multipart/form-data for Post" which needs to be checked.
If your HTML looks something like this input type="file" name="dataFile" id="fileChooser"/>" your parameter name must be "dataFile" which is the name of the input file field.
You can also use a sniffer tool like fiddler for example or the HTTP/S script recorder JMeter has to capture the request and check the MIME Type for example because I'm not sure if jpg files are "image/jpg" MIME Type

Make sure those are correctly formatted and check out what BlazeMeter says about uploading files
