IBM Version 5 manual Application deployment and testing, Retrieval function

10.3.4 Retrieval function

This registration application does not offer the retrieval function. To add the retrieval function to CustomerXML class, we add retrieve method as Example 10-15. This function retrieves Enterprise bean by the membership key, then copy the properties from customer EJB to customer bean.

Example 10-15 Retrieval function

protected void retrieve(Long membership) throws RemoteException, FinderException

{

CustomerFactory factory = new CustomerFactory(); registration.Customer ejbean = factory.findByPrimaryKey(new

CustomerKey(membership));

setFirstName(ejbean.getFirstName());

setLastName(ejbean.getLastName());

setEmail(ejbean.getEmail());

setMembership(membership);

}

In the next chapter, we show how to include the retrieve function into the registration form. At this time, we add a statement to confirm the registration. In the doPost method, we retrieve the customer using the membership key just after create (see Example 10-16).

Example 10-16 Confirming the creation

try{

xml.retrieve(new Long(request.getParameter("membership"))); showPage(resultStylesheet, response);

}catch(FinderException remoteEx){

}

10.4 Application deployment and testing

We are now ready to generate the deployed code to support the execution on WebSphere test environment:

1.Switch to the J2EE Hierarchy view, select the CustomerInfoEJB under the EJB Modules, and select Generate—>Deploy and RMIC Code.

2.Make sure that the customer entity EJB is selected, and click Finish, as in Figure 10-28.
