Add servlet Filter utility class managing a PersistenceManager per request
--------------------------------------------------------------------------

Key: JDO-398
URL: http://issues.apache.org/jira/browse/JDO-398
Project: JDO
Issue Type: Task
Components: util20
Affects Versions: JDO 2 final
Reporter: Michael Bouschen
Assigned To: Michael Bouschen
Priority: Minor
Fix For: JDO 2 maintenance release 1


I propose to add a new class JDOFilter implementing a servlet filter (interf
ace javax.servlet.Filter) to a new package org.apache.jdo.util.web for web s
upport utility classes. The filter init method creates a PMF instance. Metho
d doFilter creates a Persis
tenceManager, stores it as a request attribute and then calls the filter cha
in. It closes the PersistenceManager after the chain returns. The PMF is clo
sed in the filter method destroy.
