Hi All,

I wanted to know if we can attach multiple document while starting a JBPM Process.

I am using JBPM 7.59.0.Final Running on Wildfly container.

I created a process with "org.jbpm.document.service.impl.DocumentCollectionImpl" Implementation and wanted to know how the payload looks like for sending multiple documents while starting a process through the kie-server api.

The Script which i currently use is.

import requests
import json


payload = json.dumps({
  "doc": {
    "org.jbpm.document.service.impl.DocumentCollectionImpl": {
      "identifier": "factura 1.pdf",
      "name": "factura 1.pdf",
      "link": "",
      "size": "",
      "lastModified": "",
      "content": "BASE64 content"
    }
  } 
})
headers = {
  'Accept': 'application/json',
  'Authorization': 'Basic a2llc2VydmVyOmtpZXNlcnZlcjEh',
  'Content-Type': 'application/json'
}

response = requests.request("POST", url, headers=headers, data=payload)

print(response.text)

I've used the "DocumentCollectionImpl" in the past and my payload looks like this:
suppose you have a process variable called "documents" of type "org.jbpm.document.service.impl.DocumentCollectionImpl"

"documents": {
"org.jbpm.document.service.impl.DocumentCollectionImpl": {
"documents": [
{
"identifier": "Quartely Earnings Report.txt",
"name": "Quartely Earnings Report.txt",
"content": "dGVzdCBkYXRhIDEK",
"lastModified": 1600865448290,
"size": 1000,
"attributes": {
"type": "Earnings Report"
}
},
{
"identifier": "Press Release 1.txt",
"name": "Press.txt",
"content": "dGVzdCBkYXRhIDEK",
"lastModified": 1600865448290,
"size": 1000,
"attributes": {
"type": "Press Release"
}
},
{
"identifier": "Credit Report1.txt",
"name": "Credit Report.txt",
"content": "dGVzdCBkYXRhIDEK",
"lastModified": 1600865448290,
"size": 1000,
"attributes": {
"type": "Credit Report"
}
},
{
"identifier": "Rating Document 1.txt",
"name": "Rating Document.txt",
"content": "dGVzdCBkYXRhIDEK",
"lastModified": 1600865448290,
"size": 1000,
"attributes": {
"type": "Rating x Document"
}
}
]
}

I hope this helps.

Hi Rafael, Thanks much, That did the trick.

Can u also let me know how can i retrieve these Document ID  in a process instance? Printing kcontext just gives me the Document Collection object.

So, "org.jbpm.document.service.impl.DocumentCollectionImpl" is a collection of "org.jbpm.document.Document"

You can iterate over DocumentCollectionImpl like this:

DocumentCollectionImpl docs = (DocumentCollectionImpl)kcontext.getVariable("documents");
System.out.println("\t received " + docs.getDocuments().size() + " doc(s)");

List<String> _docTypes = new ArrayList<>();
for(org.jbpm.document.Document doc: docs.getDocuments()){
System.out.println("Received Doc: " + doc.toString());
_docTypes.add(doc.getAttributes().get("type"));
}
System.out.println("\t docTypes: " + _docTypes);
kcontext.setVariable("docTypes", _docTypes);
