How to pass a document as an attachment to a BPEL process?

Question

Hi Guys,
Currently I have a BPEL process that get's invoked from a JSP page with some scriplets in it. The following bit of code calls the BPEL process in the JSP scriplet:
try{       
String givenNames = request.getParameter("givenNames");
String sex = request.getParameter("sex");
String title = request.getParameter("title");
String staffMemberInd = request.getParameter("staffMemberInd");
String deceasedInd = request.getParameter("deceasedInd");
String archiveExclusionInd = request.getParameter("archiveExclusionInd");
String archiveDt = request.getParameter("archiveDt");
String purgeExclusionInd = request.getParameter("purgeExclusionInd");
String purgeDt = request.getParameter("purgeDt");
String birthDt = request.getParameter("birthDt");
String salutation = request.getParameter("salutation");
String preferredGivenName = request.getParameter("preferredGivenName");
String emailAddr = request.getParameter("emailAddr");
String autoEnableInd = request.getParameter("autoEnableInd");
String xml = "<AddUserProcessRequest xmlns=\"http://xmlns.oracle.com/callistaAddUser\">"
+"<surname>"+surname+"</surname>"
+"<givenNames>"+givenNames+"</givenNames>"
+"<sex>"+sex+"</sex>"
+"<title>"+title+"</title>"
+"<staffMemberInd>"+staffMemberInd+"</staffMemberInd>"
+"<deceasedInd>"+deceasedInd+"</deceasedInd>"
+"<archiveExclusionInd>"+archiveExclusionInd+"</archiveExclusionInd>"
+"<archiveDt>"+archiveDt+"</archiveDt>"
+"<purgeExclusionInd>"+purgeExclusionInd+"</purgeExclusionInd>"
+"<purgeDt>"+purgeDt+"</purgeDt>"
+"<birthDt>"+birthDt+"</birthDt>"
+"<salutation>"+salutation+"</salutation>"
+"<preferredGivenName>"+preferredGivenName+"</preferredGivenName>"
+"<emailAddr>"+emailAddr+"</emailAddr>"
+"<autoEnableInd>"+autoEnableInd+"</autoEnableInd>"
+"</AddUserProcessRequest>";
Locator locator = new Locator("default","bpel");
IDeliveryService deliveryService = (IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME);
// construct the normalized message and send to Oracle BPEL Process Manager
NormalizedMessage nm = new NormalizedMessage( );
nm.addPart("payload" , xml );
NormalizedMessage res = deliveryService.request("AddUser", "process", nm);
Map payload = res.getPayload();
Element partEl = (Element) payload.get("payload");
In my BPEL process I have a human task that I want to attach a document (WORD, PDF etc) to.
My question is, how can I attach and pass a document as an input parameter to my BPEL process? and what kind of element do I need to create in the XSD file to hold the attached document?
Any help with this is greatly appreciated.
Thanks.

Answer 1

In our application, an attachment surfaces in the middle of the lifecycle, but not from the start.
We were using the following to accommodate the attachment as the part of the payload ...
<xsd:element name="AttachementMimeType" type="xsd:string"/>
<xsd:element name="AttachmentMIMEStream" type="xsd:string"/>
Hope this helps.
