JpaPersistenceUnit

We now need to create the Persistent Unit definition. We are going to create a file called persistence.xml in the src/META-INF directory with the following contents: 

persistence.xml
code format="xml"   

  

   code

The Steps

 * 1) Expand your ** **
 * 2) Select the **src** directory
 * 3) Find the **src/META-INF** directory (if one does not exist, right-click, select **New:Folder**, enter **META-INF** and press enter)
 * 4) Right click the **src/META-INF**, select **new:File**.
 * 5) Enter **persistence.xml** for the name and press "OK" (Note: all lowercase. It won't make a difference on Windows XP but it will on Unix.)
 * 6) Copy the contents (above) into the file and save it
