Section 3. Returning more complex types

HRSystem SessionBean and DeptValue Bean

I felt it would be disingenuous to create just one example that only returns simple

types. Thus, I created a more complex example that returns a complex object, for

example, a non primitive type.

You can find a more complex example in the example source code under the directory

axisEJBDepartEmployees

. This example creates and exposes a stateless session

bean called

HRSystem

. The stateless session bean is configured to work with two

Entity beans that use CMP CMR 2.0.

Here is the code for HRSystem:

package ejb;

import bean.*;

import javax.ejb.SessionBean;

import javax.ejb.SessionContext;

import java.util.*;

import util.*;

/**

* Provides a session facade that works with cmp/cmr from EJB 2.0

* based entity beans.

*

* @ejb.bean name="HRSystem" type="Stateless"

*

local jndi name="HRSystem"

*

* @ejb.ejb ref ejb name="DeptBean" view type="local"

* @ejb.ejb ref ejb name="EmployeeBean" view type="local"

*/

public class HRSystemBean implements SessionBean {

...

/**

* Get a list of all the depts.

*

* @return All the dept value objects.

*

* This method is part of the ejb interface.

* @ejb.interface method view type="both"

* @ejb.transaction type="Required"

*/

public DeptValue[] getDepartments() {

ArrayList deptList = new ArrayList(50);
