Xmlrpc - neocekavany stav – Java – Fórum – Programujte.com

Ahojte, nevim, zda s tim tu nekdo bude mit zkusenosti, ale zkusim to. Snazim se rozchodit xmlrpc server-klient (server jako servlet na webu a klient jako klasicka desktopova (swing) aplikace). Podle manualu http://ws.apache.org/xmlrpc/ chci provest server jako servlet. Mel bych tedy vytvorit nejakou tridu, kterou pak budu volat (Calculator), tady je muj kod:

package services;



public class Calculator {

	public int add(int a, int b) {

		return a + b;

	}



	public int sub(int a, int b) {

		return a - b;

	}

}

<servlet>

	<servlet-name>EOTService</servlet-name>

	<servlet-class>services.EOTService</servlet-class>

	<init-param>

		<param-name>enabledForExtensions</param-name>

		<param-value>true</param-value>

		<description>Sets, whether the servlet supports vendor extensions for XML-RPC.</description>

	</init-param>

</servlet>



<servlet-mapping>

	<servlet-name>EOTService</servlet-name>

	<url-pattern>/service</url-pattern>

</servlet-mapping>

package services;



import org.apache.xmlrpc.*;

import org.apache.xmlrpc.common.*;

import org.apache.xmlrpc.server.*;

import org.apache.xmlrpc.webserver.*;



public class EOTService extends XmlRpcServlet {

	private boolean isAuthenticated(String pUserName, String pPassword) {

		return pUserName.equals("username") && pPassword.equals("password");

	}



	protected XmlRpcHandlerMapping newXmlRpcHandlerMapping() throws XmlRpcException {

		PropertyHandlerMapping mapping = (PropertyHandlerMapping) super.newXmlRpcHandlerMapping();



		AbstractReflectiveHandlerMapping.AuthenticationHandler handler =

			new AbstractReflectiveHandlerMapping.AuthenticationHandler() {

				public boolean isAuthorized(XmlRpcRequest pRequest) {

					XmlRpcHttpRequestConfig config = (XmlRpcHttpRequestConfig) pRequest.getConfig();



					return isAuthenticated(config.getBasicUserName(), config.getBasicPassword());

				}

			};



		mapping.setAuthenticationHandler(handler);



		try {

			mapping.addHandler("Calculator", Class.forName("services.Calculator"));

		} catch (ClassNotFoundException e) {

			e.printStackTrace();

		}

		return mapping;

	}

}

HTTP method GET is not supported by this URL

try {

    XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();

    config.setServerURL(new URL("http://127.0.0.1:8080/service"));

    config.setBasicUserName("username");

    config.setBasicPassword("password");

    config.setBasicEncoding("UTF-8");

    XmlRpcClient client = new XmlRpcClient();

    client.setConfig(config);

    Object[] params = new Object[]{new Integer(33), new Integer(9)};

    Integer result = (Integer)client.execute("Calculator.add", params);



    System.out.println("33 + 9 = " + result);

} catch (java.net.MalformedURLException e) {

    System.out.println("MalformedURLException: " + e.getMessage());

} catch (org.apache.xmlrpc.XmlRpcException e) {

    e.printStackTrace(System.out);

}

Cau, mas jinou adresu serveru http://localhost:8080/eot/service a klienta http://127.0.0.1:8080/service
