  1. POextract Http Content-length from a web service response
    text
    copied!<p>I want to extract the HTTP Headers from a response, more exactly the content-length of the response in order to raise an exception if it exceeds a certain size. I've been trying to do this for two days now without any success. How can i do this and is it more clean to use an interceptor or a handler for this.</p> <p>here's a handler for logging the headers but it returns nothing</p> <pre><code>public class HeaderHandler implements SOAPHandler&lt;SOAPMessageContext&gt; { private final static Logger log = Logger.getLogger(HeaderHandler.class); private PrintStream out; public HeaderHandler() { setLogStream(System.out); } protected final void setLogStream(PrintStream ps) { out = ps; } public void init(Map c) { System.out.println("HeaderHandler : init() Called...."); } public Set&lt;QName&gt; getHeaders() { return null; } public boolean handleMessage(SOAPMessageContext smc) { System.out.println("HeaderHandler : handleMessage Called...."); logToSystemOut(smc); return true; } public boolean handleFault(SOAPMessageContext smc) { System.out.println("HeaderHandler : handleFault Called...."); logToSystemOut(smc); return true; } // nothing to clean up public void close(MessageContext messageContext) { System.out.println("HeaderHandler : close() Called...."); } // nothing to clean up public void destroy() { System.out.println("HeaderHandler : destroy() Called...."); } /* * Check the MESSAGE_OUTBOUND_PROPERTY in the context * to see if this is an outgoing or incoming message. * Write a brief message to the print stream and * output the message. The writeTo() method can throw * SOAPException or IOException */ protected void logToSystemOut(SOAPMessageContext smc) { Boolean outboundProperty = (Boolean) smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY); if (outboundProperty.booleanValue()) { out.println("\nOutbound message:"); } else { out.println("\nInbound message:"); } out.println("\n***********************************************************************************"); final Object o = smc.get(MessageContext.HTTP_RESPONSE_HEADERS); if (o != null) { out.println(o); } else { out.println("o null"); } } </code></pre> <p>}</p>
