title: why is javax.ejb.EJBException being generated when valid input is given to a page?
body: <p>i'm currently coding webpages using jsp and i'm also using java beans. i've implemented the part where the inpuuted contents are checked against the values in the database and accept the input and store it in the database. hwoever when I input valdi data in the page, the javax.ejb.EJBException exception is thown. The following is the error page:</p>
  
  <pre><code>HTTP Status 500 -
  
  type Exception report
  
  message
  
  descriptionThe server encountered an internal error () that prevented it from fulfilling this request.
  
  exception
  
  javax.ejb.EJBException
  note The full stack traces of the exception and its root causes are available in the GlassFish Server Open Source Edition 3.1.1 logs.
  </code></pre>
  
  <p><strong>does anyone of you know why this type of error is generated because I did not find any useful help on the net.</strong> Could it be maybe the contents of the persistence unit are generating the exception ?</p>
  
  <p>thanks for your help</p>
