Calling .asmx Web Service from Java Client

Question

hi
I have created one java client in WSAD 5.1 to invoke .asmx web service. I have used the following code for it.
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
import javax.xml.namespace.QName;
import javax.xml.rpc.NamespaceConstants;
import javax.xml.rpc.ParameterMode;
import java.net.URL;
public class JavaWS3
     public static void main(String [] args)
          try
               // Responds the same with or without the ?WSDL
               String     strEndPoint          = "http://www.meizlik.com/Service.asmx";
               String     strSoapAction     = "http://www.meizlik.com/BigAdd";
               String     strSchemaURL     = "http://www.w3.org/2001/XMLSchema";
               String     strParamName1     = "addend_1";
               String     strParamName2     = "addend_2";
               String     strParameterVal1= "10";
               String     strParameterVal2= "7";
               String     strFunctionName     = "BigAdd";
               //Call     call   = (Call) new Service().createCall();//Works
               //Call     call   = new Call(strSoapAction);//Works same
               //Call     call   = new Call(strEndPoint);//Works same
               Service  service = new Service();
                Call call= (Call) service.createCall();
               call.setEncodingStyle(NamespaceConstants.NSURI_SOAP_ENCODING);
               call.setTargetEndpointAddress(new URL(strEndPoint));
               // first parameter in QName seemingly takes ANYTHING
               call.setOperationName(new QName("http://www.meizlik.com", strFunctionName));
               // Set the name of the parameter and the return type
               call.setReturnType(XMLType.XSD_STRING);
               call.addParameter(new QName("http://www.meizlik.com",strParamName1), XMLType.XSD_STRING, ParameterMode.IN);
               call.addParameter(new QName("http://www.meizlik.com",strParamName2), XMLType.XSD_STRING, ParameterMode.IN);
               // Catch the result and print it
               // Parameter count is now ONE (1).
               // call.setUseSOAPAction(true);//Not Necessary
               call.setSOAPActionURI(strSoapAction);//Yes Necessary
               String     strResult = (String) call.invoke(
                    new Object[] {
                         new String(strParameterVal1),
                         new String(strParameterVal2)
               System.out.println("Result='" + strResult + "'");
          catch (Exception e)
               e.printStackTrace();
               System.out.println(e.toString());
}this code is giving me the exception as :
java.net.ConnectException: Operation timed out: connect due to invalid addressI visited web service URL http://www.meizlik.com/Service.asmx and its working fine.
I also tried Java Proxy method in WSAD 5.1 but it is showing me the same error.
Where am I wrong? Can anyone plz give me solution 4 this.
Thanks..
