Description

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.
