Jersey 2.22.1 FileDataMultiPart Header Issue - jersey

Hey at the moment i try to upload some files with the jersey client api 2.22.1. I've analyzed the calls of the cms ui to write my own service. For the upload of files i need to generate following request with jersey:
------WebKitFormBoundarydgCBaM6oYnsWZE56
Content-Disposition: form-data; name="contentItem"
{"id":2858,"properties":[{"id":5604,"alias":"dateiHochladen","value":{"selectedFiles":"uploadjava.PNG"}}],
"name":"testcms.PNG","contentTypeAlias":"DateiHochladen","parentId":2857,"action":"publish","expireDate":null,"releaseDate":null,"templateAlias":"DateiHochladen1"}
------WebKitFormBoundarydgCBaM6oYnsWZE56
Content-Disposition: form-data; name="file_dateiHochladen"; filename="uploadjava.PNG"
Content-Type: image/png
------WebKitFormBoundarydgCBaM6oYnsWZE56--
At the moment i am able to generate the upper field, but i am not able to generate the second one with name and filename. Can someone give me a hint how to do this? I've already tried to set new headers, fields, parts and contentdispositions...

Spring SOAP Mtom attachment's identifier encoding problem

I created a SOAP client in my Spring Boot (2.5.5) server.
The envelope is marshalled, the communication works, but I have got an error which said I not attached the binary (file) data.
In my log file the soap message has it and there is a binary attachment.
The only strange thing is, in the Include tags href attibute has a %40 character instead of # character like this:
...
<ns2:DocuData xmlns:ns2="namespace 1">
<ns2:fileContent>
<xop:Include xmlns:xop="http://www.w3.org/2004/08/xop/include"
href="cid:946ff3f8-e725-4cca-8108-676403be336f%40domain.hu"/>
</ns2:fileContent>
</ns2:DocuData>
...
In the multipart data section the Content-ID is:
...
------=_Part_1_22457057.1633284795352
Content-Type: application/octet-stream
Content-ID: <946ff3f8-e725-4cca-8108-676403be336f#domain.hu>
Content-Transfer-Encoding: binary
...
content
...
------=_Part_1_22457057.1633284795352--
Is it the cause of the problem? How can I solve it?
Thanks for any help!
It was my fault! I read out the data from the stream when I logged the request in the interceptor. I turned off the logging and the message sent successfully.

how to upload a.zip file in Jmeter?

I am unable to upload a .zip file from Jmeter.
Upon trying to upload the file i am getting an error like below,
{
"args":[
"unsupportedMediaType"],
"message":"Request media type is not supported",
"messageId":"unsupportedMediaType",
"correlationId":"6539cd74-5f09-473c-40d2-36f98c0a472b",
"causes":[
],
"status":415
}
HTTP Method supported: POST.
Request header:
Content-Type: application/json; charset=UTF-8
Can anyone please help me in uploading the .zip file from the Jmeter, refer to the below image for my request,
Thanks in advance.
Are you sure about your content-type and what you are doing ?
for zip content type application/json is wrong.
fileToString will try to transform byes(zip) to text which cannot work
Try
checking Use multipart/form-data for Post
and Browser compatible headers .
remove FileToString call and use last tab Files upload instead of body data. And use there the content type application/zip or something suitable
If you are trying to upload a file and send a body, you may need to use nightly build.

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

FormDataPart String wrong charset

I'm stuck with this problem for two days now. The jersey verion is 2.6.
I have enabled the logging of the request by adding a loggingfilter. Which works well.
My rerquest is logged using the right charset:
Content-Disposition: form-data; name="verskomm"
kleine Ă„nderung
Wenn I want to consume this request using #FormDataParam I get
kleine ?nderung
Where can I set the charset which should be used to decode these parts of the request?
I have no influence on the request, as it is made by a third party program.

Correct HTTP Headers for Images?

I'm writing a web server in C#, just for the fun of it, and I am able to serve basic text files to my browser. However, when serving up an image (say, image.png), all browsers that I test my server on (IE, Firefox, and Chrome) show some kind of placeholder thumbnail for the image, as if the image is corrupted or invalid.
The response that I am sending to the browser looks like
HTTP/1.0 200 Ok
Content-Type: image/png
Content-Length: 14580053
{image data here}
Am I using the correct HTTP headers? Or, if I am, why else would browsers not accept the image?
Ah, figured it out... my code forgot to add an extra \n before the response body. It wasn't a problem with the headers at all, just incorrect response syntax.
