JAXWS Soap Handler Large MTOM Attachments

Question

The JAXWS implementation within IBM WebSphere 7 and 8 appears to have some problems when it comes to soap handlers and large MTOM attachments. It appears that the entire mes

Answer 1

Here is how to access the headers without reading the entire message using the WebSphere built-in JAX-WS implementation.

public boolean handleMessage(SOAPMessageContext context) {

    AttributedURI messageIdURI = (AttributedURI)context.get("com.ibm.wsspi.wsaddressing.inbound.MessageID");
    String messageId = "";
    if (messageIdURI != null && messageIdURI.getURI() != null) {
        messageId = messageIdURI.getURI().toString();
    }
    EndpointReference fromApplicationEPR = (EndpointReference)context.get("com.ibm.wsspi.wsaddressing.inbound.FromEPR");
    String fromApplication = "";
    if (fromApplicationEPR != null && fromApplicationEPR.getAddress() != null &&
        fromApplicationEPR.getAddress().getURI() != null) {
        fromApplication = fromApplicationEPR.getAddress().getURI().toString();
    }

    ...

    return true;
}

Note that this differs based on the precise JAX-WS implementation. I'll post how to do this via Apache CXF when I get a chance. Here are the needed imports for the above code:

import com.ibm.ws.wsaddressing.AttributedURI;
import com.ibm.ws.wsaddressing.EndpointReference;
