Hello

How can I send the file to the "tempPath" folder. Because when I mail the code it tells me that the archive is missing and it's because I haven't put it.

I just sent the request using

Post http://127.0.0.1:35139/bonita/API/bpm/process/8005671248051857614/instan...

with the body:
{
"myDocumentContract": {
"filename": "07749533.pdf",
"tempPath": "tmp_8964658850826963659.pdf",
"contentType": "application/pdf"
}
}

Response

{

"exception": "class java.io.FileNotFoundException",

"message": "File Not Found"

}

Hi Medhi.

I tried with your propossal.
the new trace is:

{
"code": 415,
"contactEmail": null,
"description": "The server is refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method",
"homeRef": "/",
"reasonPhrase": "Unsupported Media Type",
"uri": "http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.4.16"
}

Hi hcastellanos,

it means that your document was correctly added. you have to use a link widget to allow users to download your document (using the document url).

Cheers,

Mehdi

Hello hcastellanos,

You should do a POST on this url :
http://localhost:8080/bonita/API/bpm/process/{{processDefinitionId}}/instantiation

with a body content that matches your process contract :

{
"myDocumentContract": { 
"filename": "07749533.pdf", 
"tempPath": "tmp_8964658850826963659.pdf", 
"contentType": "application/pdf" 
}
}

if you use the ui designer, you can use the button widget, with action "POST". in that case, the url to call is the one i specified above, and the data sent on click is the json object that matches your contract.

Cheers,

Mehdi Kettani
