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;

For Apache CXF, the best approach is to use an Interceptor which is CXF implementation specific. Below is an example custom interceptor class.

package com.company.app.interceptor;

import javax.xml.namespace.QName;

import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.binding.soap.interceptor.AbstractSoapInterceptor;
import org.apache.cxf.headers.Header;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.phase.Phase;
import org.apache.log4j.Logger;
import org.w3c.dom.Element;

public class SOAPHeaderInterceptor extends AbstractSoapInterceptor  {
    private static Logger logger = Logger.getLogger(SOAPHeaderInterceptor.class);

    public SOAPHeaderInterceptor() {
        super(Phase.USER_PROTOCOL);
    }

    @Override
    public void handleMessage(SoapMessage message) throws Fault {
        try {
            Header fromHeader = message.getHeader(new QName("http://www.w3.org/2005/08/addressing", "From"));
            Header messageIdHeader = message.getHeader(new QName("http://www.w3.org/2005/08/addressing", "MessageID"));

            String from = null;
            if (fromHeader != null && fromHeader.getObject() != null) {
                from = ((Element)fromHeader.getObject()).getTextContent();
            }
            String messageId = null; 
            if (messageIdHeader != null && messageIdHeader.getObject() != null) {
                messageId = ((Element)messageIdHeader.getObject()).getTextContent();
            }
        } catch (Exception e) {
            logger.error("Unable to read SOAP Headers", e);
        } 
    }
}

Then, in your JAX-WS service implementation class specify the @InInterceptors annotation.

@InInterceptors(interceptors ="com.company.app.interceptor.SOAPHeaderInterceptor")
