Java EE (Java Enterprise Edition) General Discussion

Hi,

I am using apache commons HttpClient for sending SOAP request to one of my vendor.
Till now I used the HttpClient 2.0. it was working fine.

When I update the HttpClient3.0, I am always getting response code 500 (server error) from vendor.

Can any one help me What is wrong in below 3.0 code snippet?

I am suspecting my ESP authentication part is not correct ....



HttpClient 3.0 code:

    static {
        // add security providers
        Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
        System.setProperty("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");
        try {
            ACCURINT_URL = new URL("https://myvendor.com/");
            HOST_CONFIG = new HostConfiguration();
            HOST_CONFIG.setHost(ACCURINT_URL.getHost(), ACCURINT_URL.getPort(), ACCURINT_URL.getProtocol());
        }
        catch (Exception ex) {
            logger.error("Unable to initilize ACCURINT url");
        }

        try{
        String secProviderName = "com.sun.crypto.provider.SunJCE";
        java.security.Provider secProvider =
            (java.security.Provider)Class.forName(secProviderName).newInstance();
        Security.addProvider(secProvider);
        }catch(Exception ex1){
             logger.error("Unable to initilize security provider");
        }
    }


    public String execute(String _request) {

        HttpClient client = new HttpClient();

        AuthScope ascope = new AuthScope("https://myvendor.com", 443, "ESP");
        client.getState().setCredentials(ascope, credentials);

        HttpConnectionManagerParams cmngr = new HttpConnectionManagerParams();
        cmngr.setConnectionTimeout(20000);
        client.getHttpConnectionManager().setParams(cmngr);

        HttpMethodParams mparam = new HttpMethodParams();
        mparam.setBooleanParameter(HttpMethodParams.USE_EXPECT_CONTINUE, true);

        PostMethod post = new PostMethod(ACCURINT_URL.getPath());
        post.setParams(mparam);
        post.setDoAuthentication(true);

        post.addRequestHeader("SOAPAction", "/MYSOAPACTION");

            logger.info("return code= "+code);
            //logger.info("re="+post.getResponseBodyAsString());
            //return post.getResponseBodyAsString();
            //return post.getResponseBodyAsStream();
            String XMLresponse = "";
            InputStream in = post.getResponseBodyAsStream();
            if(in != null){
                ByteArrayOutputStream bos = new ByteArrayOutputStream();
                byte[] buf = new byte[1024];
                int len;
                while ((len = in.read(buf)) > 0) {

            }
            //return new AccurintReportResponse(XMLresponse,true);
            return XMLresponse;
        }
        catch (IOException ioex) {
            logger.error("Unable to get response from " + URL.getHost(), ioex);
