Try deploying the sample web services and run the sample clients. The client will print the SOAP request/envelope log. If you use eclipse you can use the soap request monitoring feature.

With a MessageHandler you can see the SOAP Message too.
Look here:
http://labs.jboss.com/portal/jbossws/user-guide/en/html/headers-handlers.html

In a JSR-181 endpoint you can user the @HandlerChain annotation

@HandlerChain(name = "handlerChain", file = "resource://META-INF/handler.xml")

<?xml version="1.0" encoding="UTF-8"?>
<handler-config>
 <handler-chain>
 <handler-chain-name>handlerChain</handler-chain-name>
 <handler>
 <handler-name>MessageHandler</handler-name>
 <handler-class>package.MessageHandler</handler-class>
 </handler>
 </handler-chain>
</handler-config>

public class FeatureScanMessageHandler extends GenericHandler{

 public FeatureScanMessageHandler(){
 }

 public boolean handleMessage(SOAPMessageContext messageContext) {
 return true;
 }

 public boolean handleResponse(MessageContext context) {
 return true;
 }

 public QName[] getHeaders() {
 return this.getHeaders();
 }

 public boolean handleFault(MessageContext msgContext) {
 return true;
 }
}
