MessageContext in SOAPHandler JAX-WS WebService

Question

I have a JAX-WS 2.2 WebService and I must take the IP Address of each client that communicate with it. I write a SOAP protocol handler but I can't see the addresses because the handlers doesn't contain this information and using the mimeheaders I can't also see this information. The code of my handler is the follow:

public class AddressHandler implements SOAPHandler<SOAPMessageContext> {

private void takeIPAddress(SOAPMessageContext context) {

    try {
        SOAPMessage original = context.getMessage();
        MimeHeaders mimeheaders = original.getMimeHeaders();
        MimeHeader mimeheader = null;

        Iterator<?> iter = mimeheaders.getAllHeaders();

        for (; iter.hasNext();) {
            mimeheader = (MimeHeader) iter.next();

            System.out.println("name=" + mimeheader.getName() + ", value="
                    + mimeheader.getValue());
        }


     } catch (Exception e) {
         e.printStackTrace();
     }


}

@Override
public void close(MessageContext arg0) {
    // TODO Auto-generated method stub

}

@Override
public boolean handleFault(SOAPMessageContext arg0) {
    // TODO Auto-generated method stub
    return false;
}

@Override
public boolean handleMessage(SOAPMessageContext context) {
    takeIPAddress(context);
    return true;
}

@Override
public Set<QName> getHeaders() {
    // TODO Auto-generated method stub
    return null;
}
}

Now I'm seeing that would be possible to see the addresses using the following code:

SOAPMessageContext jaxwsContext = (SOAPMessageContext)wsContext.getMessageContext();
HttpServletRequest request = HttpServletRequest)jaxwsContext.get(SOAPMessageContext.SERVLET_REQUEST);
String ipAddress = request.getRemoteAddr();

But I can't import correctly the HttpServletRequest class. Do you have any ideas?

UPDATE

Thanks to A Nyar Thar, I've seen that exists another method to take address and I've implemented this in my code, that now is:

private void takeIPAddress(SOAPMessageContext context) {

    HttpExchange exchange = (HttpExchange)context.get("com.sun.xml.ws.http.exchange");
    InetSocketAddress remoteAddress = exchange.getRemoteAddress();
    String remoteHost = remoteAddress.getHostName();

    System.out.println(remoteHost);     

}

But the code execution create this error (where row 39 is where I do exchange.getRemoteAddress()):

I think that the real problem is that I don't know how take WebServiceContext from my class AddressHandler. Do you have ideas?

Solution

For JAX-WS based webservice, you can access remote host info from javax.xml.ws.spi.http.HttpExchange, that can be accessed based on JAX-WS version,

• JAX-WS 2.1

  SOAPMessageContext soapContext = (SOAPMessageContext)wsContext.getMessageContext();
  HttpExchange exchange = (HttpExchange)soapContext.get(JAXWSProperties.HTTP_EXCHANGE);
  

• JAX-WS 2.2

  SOAPMessageContext soapContext = (SOAPMessageContext)wsContext.getMessageContext();
  HttpExchange exchange = (HttpExchange)soapContext.get("com.sun.xml.ws.http.exchange");
  

Note that wsContext.getMessageContext() will return MessageContext. If you want it, don't cast to SOAPMessageContext, like that,

MessageContext msgContext = wsContext.getMessageContext();

Finally you can access remote address info,

InetSocketAddress remoteAddress = exchange.getRemoteAddress();
String remoteHost = remoteAddress.getHostName();

@hasmet Hope that is what you want.

[hasmet]

Thanks A Nyar Thar, but this method didn't work and I have an error :( I've updated my question with the error

[hasmet]

The realt problem is that I don't know how take WebServiceContext from my class

[hasmet]

Finally I've implemented this part using your code in another side of server without using the handlers.....Thank you again A Nyar Thar

I'm running a standalone application with a Jetty embedded server, soapContext.get("com.sun.xml.ws.http.exchange") is returning null; help is highly appreciated.
