Hello,

Assuming that a document is declared with the name "myDocument" in your process definition:

String attachment = "myDocument";
org.bonitasoft.engine.bpm.document.Document srcDocument =
                                processAPI.getLastDocument(processInstanceId, attachment);                     
                if(srcDocument==null){
                        throw new ConnectorException("Unable to retrieve attachment referenced by " + attachment);
                }      
                final byte[] content = processAPI.getDocumentContent(srcDocument.getContentStorageId());               
                final ByteArrayInputStream inputStream = new ByteArrayInputStream(content);
                String fileName = srcDocument.getContentFileName();
                String mimeType = srcDocument.getContentMimeType();

Then you have to read this stream to write a file on your drive.

The code above seems to be sending a file up, not bringing it down to the PC,. Do you have an example of this, if possible while also using the File/Directory dialog to ask where to put the document...

Thanks
