Accessing secure restful web services using jersey client

I have created web services based on Jersey (auto generated via Netbeans).

I have also created a user names “testClient” with password “secret” and created User group “Users” and used file Realm using glassfish 3.0.1 admin console.

I have also mapped web.xml and sun-web.xml accordingly.

My web services are secured successfully; as I access the web site I receive a security warning and then I am prompt to give username and password to access any content of the website. It is working fine when accessed开发者_C百科 via web browser.

Now I have written a simple client based on jersey and tried to access the web services offered by the 1st project; the client code is here

Auto generated Jersey client code

public class JerseyClient {
    private WebResource webResource;
    private Client client;
    private static final String BASE_URI = "https://localhost:9028/testsecurity2/resources";

    public JerseyClient() {
        com.sun.jersey.api.client.config.ClientConfig config = new com.sun.jersey.api.client.config.DefaultClientConfig(); // SSL configuration
        // SSL configuration
        config.getProperties().put(com.sun.jersey.client.urlconnection.HTTPSProperties.PROPERTY_HTTPS_PROPERTIES, new com.sun.jersey.client.urlconnection.HTTPSProperties(getHostnameVerifier(), getSSLContext()));
        client = Client.create(config);
        webResource = client.resource(BASE_URI).path("manufacturers");
    }

    public <T> T get_XML(Class<T> responseType) throws UniformInterfaceException {
        return webResource.accept(javax.ws.rs.core.MediaType.APPLICATION_XML).get(responseType);
    }

    public <T> T get_JSON(Class<T> responseType) throws UniformInterfaceException {
        return webResource.accept(javax.ws.rs.core.MediaType.APPLICATION_JSON).get(responseType);
    }

    public void close() {
        client.destroy();
    }

    public void setUsernamePassword(String username, String password) {
        client.addFilter(new com.sun.jersey.api.client.filter.HTTPBasicAuthFilter(username, password));
    }

    private HostnameVerifier getHostnameVerifier() {
        return new HostnameVerifier() {

            @Override
            public boolean verify(String hostname, javax.net.ssl.SSLSession sslSession) {
                return true;
            }
        };
    }

    private SSLContext getSSLContext() {
        javax.net.ssl.TrustManager x509 = new javax.net.ssl.X509TrustManager() {

            @Override
            public void checkClientTrusted(java.security.cert.X509Certificate[] arg0, String arg1) throws java.security.cert.CertificateException {
                return;
            }

            @Override
            public void checkServerTrusted(java.security.cert.X509Certificate[] arg0, String arg1) throws java.security.cert.CertificateException {
                return;
            }

            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };
        SSLContext ctx = null;
        try {
            ctx = SSLContext.getInstance("SSL");
            ctx.init(null, new javax.net.ssl.TrustManager[]{x509}, null);
        } catch (java.security.GeneralSecurityException ex) {
        }
        return ctx;
    }

}

Code in Main Method; uses auto generated code

JerseyClient client = new JerseyClient();
client.setUsernamePassword("testClient", "secret");
Object response = client.get_XML(String.class);
// do whatever with response
client.close();

I also want to inform that these are two different projects running on different servers both are glassfish 3.0.1. I also tried to run client and services on the same server but all in vain. I am stuck; kindly help me.

Cheers!

i have found a good resource regarding my problem. Here it is

http://wiki.open-esb.java.net/attach/RestBCEchoSSL/SslClient.java

I made few changes in my code regarding the given source and it worked perfectly. Actually I was not passing the certificate and key stores properly.

Here is the full code.
