Hello,
testing Apache XML-RPC 3.0rc1 and Java 1.6.0-beta the exception
"IncompatibleClassChangeError" was thrown.
Using Java 1.5 the program runs well.
import java.net.*;
import org.apache.xmlrpc.client.*;
public class EchoClient {
public static void main(String args[]) throws Exception {
URL url = new URL(args[0]);
XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
config.setServerURL(url);
XmlRpcClient client = new XmlRpcClient();
client.setConfig(config);
Object[] params = {"Hallo"};
String s = (String) client.execute("echo.getEcho", params);
System.out.println(s);
String t = (String) client.execute("echo.getEchoWithDate", params);
System.out.println(t);
}
}
java -cp build;%XMLRPC_LIB% EchoClient http://localhost:50000
Exception in thread "main" java.lang.IncompatibleClassChangeError:

Java SE 6 should be upwards binary-compatible with J2SE 5.0 except for
only a few incompatibilities.
With kind regards
