[jira] Resolved: (JDO-398) Add servlet Filter utility class managing a PersistenceManager per request

     [ http://issues.apache.org/jira/browse/JDO-398?page=all ]

Michael Bouschen resolved JDO-398.
----------------------------------

    Resolution: Fixed

Any failure in initialization of the PMF results in a ServletException or in a JDOException which is a RuntimeException. Both get logged by the web container, if logging is configured to print error logs. 

I updated the implementation and checked it in (see revision 424813).

> I propose to add a new class JDOFilter implementing a servlet filter (interface javax.servlet.Filter) to a new package org.apache.jdo.util.web for web support utility classes. The filter init method creates a PMF instance. Method doFilter creates a PersistenceManager, stores it as a request attribute and then calls the filter chain. It closes the PersistenceManager after the chain returns. The PMF is closed in the filter method destroy.
