RE: [Axiom]Re: Axis2: "ContentID is null" using MTOM

Thilina,

In line with your comments, the .Net service seems to have a threshold. For very small files (<700 bytes) it puts its base64 representation inside the soap envelope. For larger files I get several MIME sections as expected.

In Axis2/Axiom, is there a way to tell whether an MTOM attachment is present?

Thank you!

Ivan.

Receiving binary can happen as either MTOM attachments or as Base64 encoded text. In the case of Base64 user has to explicitly specify that the content is binary, before calling getDataHandler(), getInputStream()....

As you can see in this message no MTOM attachments are present in the response, eventhough a MIME envelope is used. Binary file is in lined using base64 encoding.

<fileData>TmFocmdpcw==</fileData>

You need to add the following before calling for getDataHandler.

binaryNode.setOptimize(true);

Even though it works, IMHO above method is not the clean way to do this.. Because of that I'm going to introduce the setBinary(boolean value) method to OMText.. You will be able to get that method in SVN head in couple of hours.

Hi,

I'm using Axis2 to call a .Net service which returns a binary file. I've
read the documentation and followed the examples, and both parties are
using MTOM. But when my code runs:

OMElement elem = (OMElement)it.next();
...
OMText binaryNode = (OMText)elem.getFirstOMChild();
DataHandler actualDH = (DataHandler)binaryNode.getDataHandler();

The last instruction causes:

java.lang.RuntimeException: ContentID is null

org.apache.axiom.om.impl.llom.OMTextImpl.getDataHandler(OMTextImpl.java:
339)

       at edu.uga.cviog.itos.ws.Client.main(Client.java:36)
