title: How to configure & package a simple Java app to use JPA
body: <p>I'm trying to learn JPA and I want create a simple Java command line app that will use JPA to query and update a database table.  I mapped out the the simple code needed to do this.  But I don't know how to configure the directory structure, where to place the persistence.xml file, packaging and so on.  This is just a quick and dirty learning exercise so I want to keep this as simple as possible.  Can someone spell out the steps in order to do this?</p>
  
  <p>I'm using Weblogic 10.3.</p>
