I have a server-side JAX-WS SOAPHandler (on WebSphere v8) that in certain cases needs to respond to the client with a SOAP response that it has in a String variable (let's call it responseXml).
When responseXml contains a successful (i.e., non-fault) SOAP message, JAX-WS sends the response to the client correctly. However, when responseXml contains a SOAP fault message, an "Internal Error" occurs, and the client gets a different fault response than the one in responseXml, as shown here:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<soapenv:Fault xmlns:axis2ns1="http://schemas.xmlsoap.org/soap/envelope/">
<faultcode>axis2ns1:Server</faultcode>
<faultstring>Internal Error</faultstring>
<detail/>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
The following error is written to the console:
[10/9/12 12:21:04:177 EDT] 00000025 AxisEngine E org.apache.axis2.engine.AxisEngine receive An error was detected during JAXWS processing

Here is a simplified SOAPHandler that illustrates this problem. (Note that the value of responseXml shown here is just an example. In my actual SOAPHandler, the responses are not hard-coded but are read from a database. I'm just trying to show the simplest sample code possible.)
package simplified.demo;
import java.io.ByteArrayInputStream;
import java.util.Set;
import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;
public class FaultyHandler implements SOAPHandler<SOAPMessageContext> {
@Override
public boolean handleMessage(SOAPMessageContext context) {
Boolean outbound = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
if (!outbound) {
String responseXml = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\"><soapenv:Header></soapenv:Header><soapenv:Body><soapenv:Fault><faultcode>soapenv:Server</faultcode><faultstring>ORA-01031: insufficient privileges</faultstring><detail/></soapenv:Fault></soapenv:Body></soapenv:Envelope>";
try {
SOAPMessage newMsg = createSOAPMessage(responseXml);
context.setMessage(newMsg);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
return (outbound);
}
private SOAPMessage createSOAPMessage(String responseXml) {
try {
ByteArrayInputStream in = new ByteArrayInputStream(responseXml.getBytes());
MessageFactory messageFactory = MessageFactory.newInstance();
return messageFactory.createMessage(null, in);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
@Override
public boolean handleFault(SOAPMessageContext context) {
return true;
}
@Override
public Set<QName> getHeaders() {
return null;
}
@Override
public void close(MessageContext context) {
}
}
I get the exact same error when I code the SOAPHandler to create a SOAPFault object (using a SOAPFactory) and throw it in a SOAPFaultException.
Based on the stack trace, I looked at the source code for JAXWSMessageReceiver, and it looks like under the covers, Axis2 is looking for a causedByException, but of course in this case there isn't one.
Does anyone know why this is happening or how it can be fixed? Thanks!
