A Java Client

import java.util.*;

import org.apache.xmlrpc.*;

public class JavaClient {

public static void main (String [] args) {

try {

XmlRpcClient server = new XmlRpcClient("http://localhost/RPC2");

Vector params = new Vector();

params.addElement(new Integer(17));

params.addElement(new Integer(13));

Object result = server.execute("sample.sum", params);

int sum = ((Integer) result).intValue();

System.out.println("The sum is: "+sum);

} catch (Exception exception) {

System.err.println("JavaClient: " + exception);

}

}

}

• This line sends the request to the server. The procedure sum(17,13) is called on the server as if it were a local procedure. The return value of a procedure call is always an Object.

• “sample” denotes a handler that is defined in the server.

• The parameters of the procedure call are always collected in a Vector.
