getContentType returns NULL for a list of attachments

[RobRZDZ]

Hello.

I'm designing a process whose input document is a doc which contains a couple of attach (and an XML portion of data); during the life of the process, I use the AssignTask service to render a form in workspace and allow a "backend" user to complete the form.

Such user can also add notes and attachments.

I programmed the AssignTask as to output attachments in a list named "doclist".

As soon as the backend user confirms the form, I created a Script in executeScript whose role is to prepare a DDX string as to produce a new document with attachs; in the code I iterate the list as to get:

     . the attachname using doc.getAttribute("wsfilename");

     . the mime-type using doc.getContentType();

The former does work (I'm able to see the name of the attachs/notes) but the getContentType always returns NULL.

I see that Xpath does offer the getDocContentType but I'm trying to avoid having too much processes and I think getContentType() should give the same results.

This is the piece of code I'm writing:

=== cut here === 8< ===

import java.util.List;
import java.util.HashMap;
import java.util.Map;
import java.util.Iterator;
import com.adobe.idp.Document;

List docList = patExecContext.getProcessDataListValue("/process_data/doclist");

Map attachMap = new HashMap();

Iterator it = docList.iterator();

String ddx = "<?xml version='1.0' encoding='UTF-8'?>";
ddx +=        "<DDX xmlns='http://ns.adobe.com/DDX/1.0/'>";
ddx +=        "<PDF result='doc_out.pdf'>";

while (it.hasNext()) {

    Document attDoc = (Document) it.next();
    String name = (String) attDoc.getAttribute("wsfilename");
    System.out.println("Aggiungo alla lista "+name);
    String mtype = (String)attDoc.getContentType();
    if (mtype != null && mtype.length() == 0) {
        mtype="application/octet-stream";
    }

    System.out.println("Mime type: "+mtype);
    attachMap.put(name,attDoc);
    ddx += "<FileAttachments source='"+name+"' namekey='*'>";
    ddx += "<File filename='"+name+"' mimetype='"+mtype+"' />";
    ddx +="</FileAttachments>";
}

ddx += "<PDF source='docesaminato' />";
ddx += "</PDF>";
ddx += "</DDX>";

patExecContext.setProcessDataMapValue("/process_data/attach_map",attachMap);
patExecContext.setProcessDataStringValue("/process_data/ddx_string",ddx);

What am I missing?

I'm still learning LCES so please be patient... :-)

Rob,

If you don't explicitly set the content type when you build 'docList' you will may a content type of null when you retrieve the document from the list.

Steve,

thanks for your comment.

The document which comes in input already has a couple of attachs; when the form gets rendered in WorkSpace, the user is able to see the attachs and he's also able to create new notes & attachs.

When he exits the WorkSpace, the service itself returns the list of notes/attachs in a doclist, including the new ones created in WS so I don't have control over the contenttype of notes/attachs __created__ in WS.

I think I can get the contenttype of the attach when the doc first gets in but how do I get the contenttype of notes/attachs created in WS?

Thanks again,

Rob

OK, let me explain a bit more.

The process I'm presently designing accepts an input document (variable type = document) which may contain attachments; the starting point is a processFormSubmission service which has:

[Input]

. Submitted Form Data (variable) -> inputdocument (type=document)

[Output]

. Attachments (variable) -> doclist (type=list of documents)

Then the processFormSubmission completes, I have the list of attachs in the doclist variable. When I iterate through it using code embedded into an executeScript service, I'm able to retrieve the NAME/WSFILENAME of the attach but __NOT__ the contenttype.

Here is the code:

=== cut here === 8< ===

import java.util.List;
import java.util.Iterator;
import com.adobe.idp.Document;

List attachList = patExecContext.getProcessDataListValue("/process_data/doclist");

List newList = new ArrayList();
List nameList = new ArrayList();

Iterator it = attachList.iterator();

while(it.hasNext()) {
    Document attDoc = (Document) it.next();
    String name = (String) attDoc.getAttribute("name");
    attDoc.setAttribute("wsfilename",name);
      nameList.add((String)name);
    if (newList.add((Document)attDoc) != true) {
        System.out.println("Error while inserting into the newList");
    }
      String mtype = (String)attDoc.getContentType();
      System.out.println("Name: "+name+" - mtype: "+mtype);
}

patExecContext.setProcessDataListValue("/process_data/doclisttask",newList);
patExecContext.setProcessDataListValue("/process_data/attach_name_list",nameList);

=== cut here === 8< ===

When the above does execute, I see the following in Jboss output:

2009-09-21 12:37:42,312 INFO  [STDOUT] Name: logo1.JPG - mtype: null
2009-09-21 12:37:42,312 INFO  [STDOUT] Name: logo1.gif - mtype: null

Is it expected?

Since the above doclist provides the list of attach for the AssignTask service, the content type is empty both before the service starts and after it completes (with or without notes/attach added using the WorkSpace).

Perhaps I'm using the wrong method but is the above expected (ie, not being able to retrieve the content/type of the attachments)?

Cheers,

Did you figure this out? I have the same problem inside of workspace. A user attaches documents to a pdf before they submit and there is nothing in the ContentType. I NEED the ContentType in order to submit the document after into ContentSpace.

[RobRZDZ]

Hi Brad.

No, I never figured it out :-( but since I was working on a prototype project which never get into production, I gave up and manually assigned the "application/octect-stream" type to every document which got attached in WorkSpace.

At a given point, I was about to manually (by code) assign the mime-type given the filename extension (eg, for .3dm  ->  x-world/x-3dmf,
.3dmf   -> x-world/x-3dmf, .pdf   -> application/pdf) but I ended up by assigning the default "application/octect-stream" type).

For your convenience, I'm attaching the list I was able to gather.

I discovered that some versions of Acrobat or Reader work while others do not. Acrobat 9 Pro does not include the content type when it assembles it's list of attachments even though it includes everything else. Reader 10 works for many file types but not all. In the end I created a script that checks to see if content type is NULL and if so figure it out based on the mapping you suggested. I built up a HashMap and looked up content type based on the file extension.
