create skeleton with WSDL

[soraya penina]

when I create skeleton with WSDL using this command -> java -cp .;%AXISCLASSPATH% org.apache.axis.wsdl.WSDL2Java --server-side --skeletonDeploy true math.wsdl
File MathServiceSoapBindingImpl.java was generated..
the code which is in the file is:

package soraya.is.praktikum.MathService;
 
public class MathServiceSoapBindingImpl implements soraya.is.praktikum.MathService.MathHandler{
    public int addNumber(int firstNumber, int secondNumber) throws java.rmi.RemoteException {
        return -3;
    }
 
}

now, i want asked all of you, why the method return -3??
I have read code of math.wsdl..but i didn't find clue for it..

can you all explain it for me??

Hi

There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.


With reference to your question, can you please copy & paste your wsdl so that it can give some clue ?

Thanks!

The WSDL2Java emitter add the arbitrary return types (null for String) -3 in your case which needs to be modified in your SoapBindinImpl class to bind it with your functionality provider. Since, this value has nothing to do with your custom WSDL, please update the return statement with the actual implementinn method from the provider.

sorry....can you explain it with more detail??
what -3 is default value if create skeleton with WSDL??

Thanks,

Creating a java class with the operations (read methods) returning Integer types have the arbitrary integer value of -3 assigned to the return type; as the WSDL2Java utility class is NOT aware of your functionality provider:

For example - I created a SoapBindingImpl class from WSDL2Java with the following code:

/**
 * CalculatorSoapBindingImpl.java
 *
 * This file was auto-generated from WSDL
 * by the Apache Axis 1.4 Apr 22, 2006 (06:55:48 PDT) WSDL2Java emitter.
 */
 
package org.nitin.test;
 
public class CalculatorSoapBindingImpl implements org.nitin.test.Calculator{
    public int substract(int in0, int in1) throws java.rmi.RemoteException {
        return [B]-3[/B];
    }
 
    public int add(int in0, int in1) throws java.rmi.RemoteException {
        return [B]-3[/B];
    }
 
}

Here, for both the add and subtract methods, the return type has been assigned as -3 which we definitely need to change.

We need to make the following changes to bind WS with the functionality provider:

/**
 * CalculatorSoapBindingImpl.java
 *
 * This file was auto-generated from WSDL
 * by the Apache Axis 1.4 Apr 22, 2006 (06:55:48 PDT) WSDL2Java emitter.
 */
 
package org.nitin.wssample.ws.generated;
 
[B]import org.nitin.wssample.SimpleCalculator;[/B]
 
public class CalculatorSoapBindingImpl implements org.nitin.wssample.ws.generated.Calculator{
[B]private SimpleCalculator calc = new SimpleCalculator();[/B]
    public int substract(int in0, int in1) throws java.rmi.RemoteException {
        return [B]calc.substract(in0, in1)[/B];
    }
 
    public int add(int in0, int in1) throws java.rmi.RemoteException {
        return [B]calc.add(in0, in1)[/B];
    }
 
}

Where the modifications made are depicted in bold.

It does not matter what arbitrary values your method returns, which in this case we have learnt is -3; what matters is the binding the service with the provider (in this case it is SimpleCalculator).

Hope this helps a bit!
