Hey all

okay with the additional work i did with Jsoup, I have made a update to this problem.
See the below code snippet for a Jsoup solution to this problem.

create a downloadFile.js file and deploy it along with the above bpmn file.

The downloadFile.js has the following content:

function downloadFile(fileUrl)
{
  with (new JavaImporter(org.jsoup, java.io.BufferedInputStream))
  {
    var doc = Jsoup.connect(fileUrl)
                    .method(Java.type('org.jsoup.Connection.Method').GET)
                    .timeout(30000)
                    .ignoreContentType(true)
                    .execute()

    var bodyStream = doc.bodyStream()

    return bodyStream
  }
}

function saveFile(fileStream, fileName, mimeType)
{
  var file = Java.type('org.camunda.bpm.engine.variable.Variables')
                 .fileValue(fileName)
                 .file(fileStream)
                 .mimeType(mimeType)
                 .create()

  execution.setVariable(fileName, file)

}

function downloadAndSaveFile(fileUrl, fileName, mimeType)
{
  var file = downloadFile(fileUrl)
  saveFile(file, fileName, mimeType)
}

downloadAndSaveFile('http://www.pdf995.com/samples/pdf.pdf', 'mypdf.pdf', 'application/pdf')

The downloadAndSaveFile() function is a helper function hat saves you some time. and lets you download the file and save it as a Camunda File type all in a single function.

Lots of fun use cases!
