Доброе время суток! Есть сервлет | Код |
package org.apache.xmlrpc.demo;
public class Calculator {
public int add(int i1, int i2) {
return i1 + i2;
}
public int subtract(int i1, int i2) {
return i1 - i2;
}
}
|
так вот я его ложу в <tomcat>/webapps/xmlrpc/WEB-INF/classes/org/apache/xmlrpc/demo/ Calculator.class создаю файл web.xml в <tomcat>/webapps/xmlrpc/WEB-INF/ стаким вот содержанием | Код |
<servlet>
<servlet-name>XmlRpcServlet</servlet-name>
<servlet-class>org.apache.xmlrpc.webserver.XmlRpcServlet</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>XmlRpcServlet</servlet-name>
<url-pattern>/xmlrpc</url-pattern>
</servlet-mapping>

создаю файл XmlRpcServlet.properties в <tomcat\>webapps\xmlrpc\WEB-INF\classes\org\apache\xmlrpc\webserver\ в нем прописываю Calculator=org.apache.xmlrpc.demo.Calculator есть клиенская часть | Код |
package org.apache.xmlrpc.demo.client;
import java.io.IOException;
import java.net.URL;
import org.apache.xmlrpc.XmlRpcException;
import org.apache.xmlrpc.client.XmlRpcClient;
import org.apache.xmlrpc.client.XmlRpcClientConfigImpl;
import org.apache.xmlrpc.client.XmlRpcCommonsTransportFactory;
public class Client {
public static void main (String [] args) throws XmlRpcException, IOException {
XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
config.setServerURL(new URL("http://localhost:8080/xmlrpc/"));
XmlRpcClient client = new XmlRpcClient();
client.setTransportFactory(new XmlRpcCommonsTransportFactory(client));
client.setConfig(config);
Object[] params = new Object[]{new Integer(2), new Integer(3)};
Integer result = (Integer) client.execute("Calculator.add", params);
System.out.println(result);
}
}

но при вызове возникает exception | Код |
