venujTry this simple webservice client.
You will need apache-axis.jar in your classpath. The following client is apache axis based. A similiar client can be built also using the JAX-WS only[without apache-axis.jar].
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
public class WEBSERVICE_CLIENT{
public static void main(String [] args) {
try {
String endpoint ="<YOUR WS ENDPOINT>";
        Service  service = new Service();
        Call     call    = (Call) service.createCall();
        // YOU CAN SET VARIOUS PROPERTIES IN THE "CALL" OBJECT...LIKE
        // USERNAME,PASSWORD,PROPERTIES OF HTTP HEADER. SEE "CALL" OBJECT'S API FOR MORE PROPERTIES.
        call.setTargetEndpointAddress( new java.net.URL(endpoint) );
        call.setOperationName(new QName("<YOUR WS SERVICE NAMESPACE>", "<WS SERVICE TO BE INVOKED>"));
        String msg = (String) call.invoke( new Object[] { "data" } );
        System.out.println("RETURNED MESSAGE : "+msg);
      } catch (Exception e) {
        System.err.println(e.toString());
}
