Writing Java Service Class

This section gives a general method to write a Java Class for any Web Service. This method is adopted by me and to be sure I dont know if its the best method , anyway everybody is free to use their style of coding the class.

The JavaToWSDL tool does not care how you are getting the work done , it just concerns about the datatypes your service is returning and the datatypes its taking as input.

Each datatype used for returning or taken as input by the service should be a JavaBean if the datatype is custom made class , default types of java are off coarse allowed :).

We will be using Eclipse and We will create a package let name it webservice1

• First create a new Java Project let name the project LearningWebService in Eclipse .
• Second, Create a DataBean class in the project which we will use as return type . One can put any datatypes in databean and then send the whole databean via service . The databean code is as follows

package webservice1 ;

import java.io.Serializable;

public class DataBean implements Serializable {

/*Put the variables which you want to

send here */

String name;

String[] sarray;

public DataBean() {}

public String getName()

{

return name;

}

public String getSarray()

{

return sarray;

}

public String setName(String name)

{

this.name=name;

}

public void setSarray(String[] sarray)

{

this.sarray=sarray;

}

}

• Now we will write the Java service class.This should be in seperate TestService.java file

package webservice1 ;

public class TestService

{

public DataBean serviceFunction(String arg1,String arg2)

// Assuming we have two input arguments

{

/*do processing with input parameters using

any java classes u want.

Let say we get a result after processing*/

String[] resultarray={"Test"," Success"};

String name="Chirag";

DataBean data=new DataBean();

data.setName(name);

data.setSarray(resultarray);

return data;

}

}

• Now create a dummy class containing a main function just to compile the above classes formed. Dummy class is as follow.

public class dummy

{

public static void main(String[] argv)

{

TestService temp=new TestService();

return;

}

}

I believe we got the .class file in the respective folder in project directory.

Now lets move to next step of creating WSDL out of this Java class file.
