How can I get it running under Tomcat?

[Richard Gomes]

Hi,

I've managed to get my tiny proof of concept running.
When I run my standalone server it responds properly to the client.


This is the client:

public class Client {

    public static void main(String[] args) throws Exception {
        // create configuration
        XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
        config.setServerURL(new 
URL("http://localhost:8080/jquantlib-xmlrpc/xmlrpc";));
        config.setEnabledForExtensions(true);
        config.setConnectionTimeout(60 * 1000);
        config.setReplyTimeout(60 * 1000);

        XmlRpcClient client = new XmlRpcClient();

        // use Commons HttpClient as transport
        client.setTransportFactory(new XmlRpcCommonsTransportFactory(client));
        // set configuration
        client.setConfig(config);

        // make the a regular call
        Object[] params = new Object[] { }; // { new Integer(2), new Integer(3) 
};
        Double result = (Double) client.execute("DayCounter.evaluate", params);
        System.out.println("Response is " + result);
    }

}


This is the server:

public class Server {
    private static final int port = 8080;

    public static void main(String[] args) throws Exception {
        WebServer webServer = new WebServer(port);

        XmlRpcServer xmlRpcServer = webServer.getXmlRpcServer();

        PropertyHandlerMapping phm = new PropertyHandlerMapping();
        /*
         * Load handler definitions from a property file.
         * The property file might look like:
         * Calculator=org.apache.xmlrpc.demo.Calculator
         * 
org.apache.xmlrpc.demo.proxy.Adder=org.apache.xmlrpc.demo.proxy.AdderImpl
         */
        phm.load(Thread.currentThread().getContextClassLoader(), 
"org/apache/xmlrpc/webserver/XmlRpcServlet.properties");

        /*
         * You may also provide the handler classes directly, like this:
         * phm.addHandler("Calculator", 
org.apache.xmlrpc.demo.Calculator.class);
         * phm.addHandler(org.apache.xmlrpc.demo.proxy.Adder.class.getName(), 
org.apache.xmlrpc.demo.proxy.AdderImpl.class);
         */
        xmlRpcServer.setHandlerMapping(phm);

        XmlRpcServerConfigImpl serverConfig = (XmlRpcServerConfigImpl) 
xmlRpcServer.getConfig();
        serverConfig.setEnabledForExtensions(true);
        serverConfig.setContentLengthOptional(false);

        webServer.start();
    }
}


I also followed the steps on ...
http://ws.apache.org/xmlrpc/xmlrpc2/server.html
...but the example is not complete and the code seems to be outdated.
In particular, the following snippets of code seem to be relative to a previous 
version:

 XmlRpcServer xmlrpc = new XmlRpcServer ();
 xmlrpc.addHandler ("examples", new ExampleHandler ());
 ...
 byte[] result = xmlrpc.execute (request.getInputStream ());
 response.setContentType ("text/xml");
 response.setContentLength (result.length());
 OutputStream out = response.getOutputStream();
 out.write (result);
 out.flush ();

When I deploy into Tomcat6, it fails like this:

Exception in thread "main" org.apache.xmlrpc.client.XmlRpcClientException:

        at org.jquantlib.xmlrpc.client.Client.main(Client.java:28)

For more information, my test can be obtained via

         svn co 
http://jquant.svn.sourceforge.net/svnroot/jquant/trunk/jquantlib-xmlrpc

Any idea?

Thanks a lot
