XML-RPC mit JAVA
Ein XML-RPC Java-Client:
import java.util.Vector;
import java.util.Hashtable;
import helma.xmlrpc.*;
public class JavaClient {
// The location of our server.
private final static String server_url =
"http://xmlrpc-c.sourceforge.net/api/sample.php";
public static void main (String [] args) {
try {
// Create an object to represent our server.
XmlRpcClient server = new XmlRpcClient(server_url);
// Build our parameter list.
Vector params = new Vector();
params.addElement(new Integer(5));
params.addElement(new Integer(3));
// Call the server, and get our result.
Hashtable result =
(Hashtable) server.execute("sample.sumAndDifference", params);
int sum = ((Integer) result.get("sum")).intValue();
int difference = ((Integer) result.get("difference")).intValue();
// Print out our result.
System.out.println("Sum: " + Integer.toString(sum) +
", Difference: " +
Integer.toString(difference));
} catch (XmlRpcException exception) {
System.err.println("JavaClient: XML-RPC Fault #" +
Integer.toString(exception.code) + ": " +
exception.toString());
} catch (Exception exception) {
System.err.println("JavaClient: " + exception.toString());
}
}
}
Ein XML-RPC Standalone JAVA Server:
import java.util.Hashtable;
import helma.xmlrpc.*;
public class JavaServer {
public JavaServer () {
// Our handler is a regular Java object. It can have a
// constructor and member variables in the ordinary fashion.
// Public methods will be exposed to XML-RPC clients.
}
public Hashtable sumAndDifference (int x, int y) {
Hashtable result = new Hashtable();
result.put("sum", new Integer(x + y));
result.put("difference", new Integer(x - y));
return result;
}
public static void main (String [] args) {
try {
// Invoke me as <http://localhost:8080/RPC2>.
WebServer server = new WebServer(8080);
server.addHandler("sample", new JavaServer());
} catch (Exception exception) {
System.err.println("JavaServer: " + exception.toString());
}
}
}
