RPC Method Based Web Service Example

This section provides a tutorial example on how to use stub and data type classes generated by WSDL2Java to invoke an RPC method based Web service.

After tested the stub class for an XML document based Web service, I want to test the stub class for an RPC method based Web service.

The WSDL document is located at http://www.herongyang.com/Service/ GetExchangeRate_WSDL_11_SOAP_11_RPC.wsdl, which defines is an RPC method based Web service with multiple input parameters.

Step 1 is to generate stub and data type classes using WSDL2Java:

C:\herong>\local\axis2\bin\wsdl2java -uri http://www.herongyang.com
   -o axis2 -d adb -s

Step 2 is to write a test program in the .\axis2\src folder:

C:\herong>cd axis2\src

C:\herong\axis2\src>type Axis2StubGetExchangeRate.java
 * Axis2StubGetExchangeRate.java
 * Copyright (c) 2009 by Dr. Herong Yang, herongyang.com
 * All rights reserved
import java.io.*;
import java.util.*;
import com.herongyang.www.service.*;
import com.herongyang.www.service.GetExchangeRateServiceStub.*;
import org.apache.axis2.transport.http.*;
class Axis2StubGetExchangeRate {
   public static void main(String[] args) {
      PrintStream out = System.out;
      try {

// Creating the stub
         GetExchangeRateServiceStub stub 
            = new GetExchangeRateServiceStub();

// Fixing org.apache.axis2.AxisFault: Transport error: 
//    411 Error: Length Required

// Building the input parameter
         GetExchangeRate request = new GetExchangeRate();
         request.setDatePart(new Date());

// Calling the operation
         GetExchangeRateResponse response 
            = stub.GetExchangeRate(request);

// Retrieving output parameter
         java.math.BigDecimal rate = response.getRatePart();

      } catch (Exception e) {

Step 3 is to compile and run the test program:



   -Djava.ext.dirs=\local\axis2\lib\ Axis2StubGetExchangeRate


Cool. This proves that WSDL2Java supports RPC method based Web services correctly.
