JPA and Web Examples using Project Woodstock and Netbeans

I was looking at some of the examples from the Netbeans site and trying to find a basic example to demonstrate. After looking at the examples I found on the web, I thought I would create a quick example myself.

First I created a project in Netbeans. I picked Java Library. Then I selected create entity classes from database and used the sample JavaDB database that comes with Netbeans. It prompted me to create the persistence.xml and I accepted the defaults.

Next I created a Web project in Netbeans. During the project creation wizard, I selected Visual JSF to include the JSF and Woodstock libraries.

Next I clicked on the properties for the project and added my library to the project.

Next I created a created a new persistence.xml file. After it was created, I modified it so that it would include the specific entity classes that I created in the library project.

Note: This is required otherwise the entity classes will not be detected.

Next I added this code snippet to SessionBean1

This fetches my data so that I can display it later in a table.

Next I compile the project (no deployment yet). This refreshes the beans so that I can manipulate them visually.

Next I create a table on Page1 from the palette. I right click the table and select binding and point it from the DefaultTableProvider to customers in the SessionBean.

Now I deploy it. Poof the magic is complete.
