Create new business logic summary

This section summarizes the tutorial.

In this tutorial, you learned that:

• Create new business logic might require a new view, controller command, task command, database table and its related enterprise bean.

• Create a new view involves the following steps:

  1. Naming the view and registering it in the view registry.

  2. Create a new properties files in which translatable text for JSP pages are stored.

  3. Create a new JSP page for the new view.

  4. Create and load access control policies for the view

• Create a new controller command involves the following steps:

  1. Register the new command in the command registry.

  2. Create an interface for the command.

  3. Create an implementation class for the command.

  4. Create and load access control policies for the command.

  5. Test the command.

• Set attributes in a data bean can be accomplished by using a controller command.

• Validate parameters that are passed in through URL commands is good programming practice.

• Create smaller task commands from a larger controller command is good programming practice.

• Create access bean to access data in a new database table is good programming practice.

• In WebSphere Commerce Developer, you can run SQL queries against the database using http://localhost/webapp/wcs/admin/servlet/db.jsp. You can also use the native tools for the database to run SQL queries.
