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

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")
