Adding attachments to task

Question

Hi, í´ve develop a solution to allow .NET applications to communicate with Oracle Workflow beacuse the Worklistmanager doesn´t work for me. So I´ve embed Java code in a java web service that manages all the api of the workflow. I have a method that allows to update the task state. And I´ve been improving it, so i decided to include a parameter that is a byte array that corresponds to a file for attach it to the task.
The code looks like this...
private Task addAttachmentToTask(IWorkflowContext oWorkflowContext,
ITaskService oTaskService, String taskId,
byte[] content) {
try {
AttachmentTypeImpl attachment;
ByteArrayInputStream attachedContent;
Task oTask;
attachment = new AttachmentTypeImpl();
attachedContent = new ByteArrayInputStream(content);
attachment.setInputStream(attachedContent);
attachment.setTaskId(taskId);
attachment.setMimeType("application/octet-stream");
oTask = oTaskService.addAttachment(oWorkflowContext, taskId,
attachment);
return oTask;
} catch (StaleObjectException e) {
this.LogText(e.toString());
return null;
} catch (WorkflowException e) {
this.LogText(e.toString());
return null;
the code is resulting in a nullpointer exception just in the line when I call the service of the workflow..
is there any documentation? Please help!

Hi, Jasmin
How to add a external file(.doc or .xls)as a attachement to a xfa form variable in process?
I've tried using the DDX and Assembler service.
When I set the input and output variable as document, the process works.
But when I set them as xfa form or document form, the process will fail by exception.
The Assembler service seems to accept the document type variable only.
the exception is :
Failure to invoke the job Assembler
Failure to invoke the job Assembler
Cannot coerce object: <document state="passive" senderVersion="0" persistent="false" senderPersistent="false" passivated="true" senderPassivated="false" deserialized="false" senderHostId="null" callbackId="0" senderCallbackId="0" callbackRef="null" isLocalizable="true" isTransactionBound="false" defaultDisposalTimeout="600" disposalTimeout="600" maxInlineSize="65536" defaultMaxInlineSize="65536" inlineSize="0" contentType="application/pdf" length="-1"><cacheId/><localBackendId><DocumentFileID fileName="C:\Documents and Settings\Administrator\Local Settings\Temp\AdobeDocumentStorage\local\docm1205306662328\b152e2c400d064ec2e16c01b547d25 d1"/><localBackendId/><globalBackendId/><senderLocalBackendId/><senderGlobalBackendId/><in line/><senderPullServantJndiName/><attributes file="C:\Adobe watch folder\Assembler\stage\Wxb7cbc144aa8e397ee4b4725a\testform3.pdf"/></document> of type: com.adobe.idp.Document to type: class com.adobe.idp.taskmanager.form.impl.xfa.XFARepositoryFormInstance

Will I need to transfer the xfa form or document form to document type? How to do that?
Or is there another way to achieve this goal?
