some problem regarding invoking web services

[Deepak T J]

hi

 

I deployed a java class as web service in apache axis and tried calling it using a client code. But i encountered some problem which i have listed after the code.

 

 import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
import org.apache.axis.utils.Options;

import javax.xml.rpc.ParameterMode;

public class client {
   public static void main(String [] args) throws Exception {
       Options options = new Options(args);

       String endpoint = "http://localhost:" + options.getPort() +
                         "/axis/employee.jws";

// Do argument checking
       args = options.getRemainingArgs();

       if (args == null || args.length != 3) {
           System.err.println("Usage: CalcClient <add|subtract arg1 arg2");
           return;
       }

       String method = args[0];
       //if (!(method.equals("add") || method.equals("subtract"))) {
       //  System.err.println("Usage: CalcClient <add|subtract arg1 arg2");
       //  return;
       //}

// Make the call
       Integer i1 = new Integer(args[1]);
       Integer i2 = new Integer(args[2]);

       Service  service = new Service();
       Call     call    = (Call) service.createCall();

       call.setTargetEndpointAddress(new java.net.URL(endpoint));
       call.setOperationName( method );
       call.addParameter("emp_no", XMLType.XSD_INT,ParameterMode.PARAM_MODE_IN);
       call.addParameter("op2", XMLType.XSD_INT, ParameterMode.PARAM_MODE_IN);

       Integer ret = (Integer) call.invoke( new Object [] { i1, i2 });

       //System.out.println("Got result : " + ret);

    }

}

 

 

when i compile the code i get the error that the "PARAM_MODE_IN symbol can be resolved"

 

since i am new to Web services and software oriented architecture, i have no clue to this error. Can someone help me put in this.

 

bye
