Scope

[M. Goodell]

I have a question regarding scope and would like clarification on something to be sure I understand things.

 

I have a sample class called AxisTest deployed on a local server that looks like:

 

public class AxisTest {
   
    private String lastName;
    private String firstName;
    private String middleName;
   
    public AxisTest() {
    }
    
    public String getLastName() {
        return this.lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getFirstName() {
        return this.firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getMiddleName() {
        return this.middleName;
    }

    public void setMiddleName(String middleName) {
        this.middleName = middleName;
    }
}

 

Here is the client class I use to talk to the server.

 

public class AxisTest {

 

    public AxisTest() {
    }
   
    public static void main(String[] args)  throws Exception {
       
        AxisTestService ams = new AxisMathServiceLocator();
        AxisTest am = ams.getAxisTest();

 

        am.setFirstName("Willy");
        am.setLastName("Wonka");
        am.setMiddleName("Wilbur");
       
        System.out.println("First Name = " + am.getFirstName());
        System.out.println("Last Name = " + am.getLastName());
        System.out.println("Middle Name = " + am.getMiddleName());

        
    }
   
}

 

When I run the client subsequent the calls to:

 

        System.out.println("First Name = " + am.getFirstName());
        System.out.println("Last Name = " + am.getLastName());
        System.out.println("Middle Name = " + am.getMiddleName());

 

all come back as null values.

 

I have read in the users guide about "scope" and if I change the scope to "Application" as in:

 

<parameter name="scope" value="Application"/>

 

then the name values are returned as they were assigned.

 

My question is this:

 

Is each method call considered a "SOAP Request" hence:

 

1. The object is created.

2. The method is called / data created.

3. The object / data is destroyed.

 

What I "think" I need is "Session-Enabled" objects and NOT application scope becuase multiple users of the object will share data.

 

Quesiton: How do you set the session-enabled attribute per object?

 

Finally, are the scope of objects in Axis similar in concept to the JSP request, session, application scopes?

 

Thank You!
