Hello i want create gui for aria2c( internet download manager ) with java for doing this aria2c has built in xmlrpc. i use xmlRpc to create gui for aria2c. in aria2c support site there is a example code for python programming language that uses xmlrpc
>>> import xmlrpclib
>>> s = xmlrpclib.ServerProxy('http://localhost:6800/rpc')
>>> s.aria2.addUri(['http://example.org/file'])
'1'i write this java code for doing this in java
package Aria2c;
import java.net.MalformedURLException;
import org.apache.xmlrpc.XmlRpcException;
import org.apache.xmlrpc.client.XmlRpcClientConfigImpl;
import java.net.URL;
import org.apache.xmlrpc.client.XmlRpcClient;
import java.util.Vector;
public class JavaClient{
private static Vector< String > params;
public JavaClient( )
{
params.add("http://rs230dt.rapidshare.com/files/344243800/10012723.LinuxCBT.Debian.part8.rar");
}
public static void main( String[] args )
{
XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
try {
config.setServerURL(new URL("http://localhost:6800/rpc"));
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
XmlRpcClient client = new XmlRpcClient();
client.setConfig(config);
try {
client.execute("aria2.addUri", params );
} catch (XmlRpcException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
}but when i want compile this i have these exceptions
