Randy Watler resolved JS2-395:
------------------------------
Resolution: Fixed
At long last this component has been added. See sping configurations in component src/test.
Thanks to DST, using "maven import" will execute the PageImporter and load the DatabasePageManager with the complete PSML content in /src/webapp/WEB-INF/pages.

[jira] Commented: (JS2-395) DB Page Manager

Randy Watler commented on JS2-395:
----------------------------------
- J2 attempted to use the OJB cache in the past, but the effort failed. In the judgement of the J2 dev team that experienced this pain first hand, it is not something that we should attempt again. Instead, components have implemented their own application level caching. There has been discussion surrounding the implementation of a distributed cache component that would be used by other components to facilitate unified cache control and notification.
- This task also must include a relaxed schema definition for MSSQL that does not support circular or self referential cascading deletes. The final schema must be developed without regard for these limitations in MSSQL, but the DB PageManager must still cascade the deletes using OJB directives so that a relaxed schema will still function properly.

Randy Watler commented on JS2-395:
----------------------------------
There may very well be a relationship, but it is not quantified at the moment.
When the OJB DB PageManager implementation is in place, it is likely that it will become the working run-time PSML implementation. Afterwords, the relationship between Castor XML, Graffito, and the DB implementation will be assessed. I believe that the Castor and Graffito PageManager implementations may well become read-only and serve primarily as PSML import plugin components.
Another related topic is the packaging of PSML documents in WAR files. A deployment mechanism related to the proposed inter-PageManager import implementation has been discussed.
In general, these musings have been very nacent and have not made their way to the list in any organized manner. Having a DB PageManager capability in place has been considered the first step before any significant progress can be made on JS2-350 or PSML deployment, so all of this will probably be post-2.0-FINAL: i.e. on the "back burner".

Randy Watler commented on JS2-395:
----------------------------------
Distributed caching will be required to make this feature work well in a clustered environment. The problem at the moment is that OJB caching is turned off by default in J2. This means that there will again be an internal cache implemented within the PageManager. This cache will have to be aged in some manner because it will not be distributed until a J2 wide cache is implemented. A distibuted cache implementation may or may not be addressed by 2.0-FINAL.
