WSRP and File Uploads

Question

Hello,
I am using BEA 8.1 SP4.
I am trying to find out the status of being able to do file uploads in portlets being displayed remotely. I have a JSR-168 portlet which simply does a file upload to the server. The JSP page that renders the content contains:
<form name="ont_mainform" method="post" action="<%=portletURI%>" enctype="multipart/form-data">
When I have the same portlet running remotely in another portal via WSRP, I get the error:
java.lang.Exception: The request does not contain a multipart/form-data or multipart/mixed stream. Content type = null
Does anyone know whether WSRP is not able to handle file uploads in the web service call just yet or is there something I need to do to get it to work? Or is this a container issue?
Thanks for any thoughts - Peter Len

Hi Peter,
By default, the consumer reads the MIME message, sends it to the
producer over SOAP, and the producer then recreates the stream for the
portlet. So, the boundary strings and the headers may not be the same.
WLP8.1SP4 also supports a mode wherein the uploaded data is transported
as a MIME attachment. For this enable accepts-mime to "true" and
transport="attachment" on the producer side in wsrp-producer-config.xml.
Here is a sample snippet.
<markup secure="false" rewrite-urls="true"
transport="string" accepts-mime="false"/>
Can you try this configuration and see if it works differently.

This is a re-copy of my last reply as it looks like the line breaks did not take.
Okay, I have run across something else which is another oddity. In the code that deals with the commons-fileupload.
I have the following code:
int boundaryIndex = contentType.indexOf("boundary="); byte[] boundary = contentType.substring(boundaryIndex +
9).getBytes();
InputStream input = req.getPortletInputStream(); MultipartStream multi = new MultipartStream(input,
boundary);
boolean nextPart = multi.skipPreamble();
// some print statements
When running the portlet locally I get:
Boundary Index: 21
Boundary Array: [B@1cccea2
InputStream: weblogic.servlet.internal.ServletInputStreamImpl@111fae9 MultipartStream: boundary='[B@17002a1' bufSize=4096 skipPreamble?: true
When running it remotely I get:
Boundary Index: 21
Boundary Array: [B@737d8a
InputStream: com.bea.wsrp.producer.container.MultipartInputStream@3708e6 MultipartStream: boundary='[B@12952ec' bufSize=4096 skipPreamble?: false
There seems to be a difference in what the InputStream object is. The key here is that the skipPreamble boolean is false for the remote portlet and that essentially keeps the code from downloading anything. Not sure if this is a commons-fileupload thing or not. Do you know of another fileupload API that you know works with remote portlets?
