static pages don't work at all with database down and XA datasource used
------------------------------------------------------------------------

                 Key: JBSEAM-4528
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-4528
             Project: Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.2.0.GA
         Environment: postgres or oracle with postgres or oracle XADatasource.  postgres jdbc driver is fine while oracle driver is not
            Reporter: deanhiller
            Priority: Critical


If this is a hibernate bug, please report hibernate issue and ticket here as other seam users will run into this problem and it looks like a seam framework problem(or at least could be solved in seam but it may be possible to solve in hibernate too and could be solved in each and every driver datasource as well).

Steps to reproduce
1. start up the jboss 5.1.0 with latest seam
2. pull your internet connection so the db is gone
3. have all your customers go to a static page like /web/error.xhtml

RESULT: jboss goes to it's knees as users in IE end up in infinite redirects to your server causing more and more load on the server.  The drivers talk to the database when they should not be.  I have a work around proxy driver for oracle's jdbc driver.  I do not however have a fix for oracle's datasource or postgres datasource.

I imagine someone could write a proxy datasource that would solve this problem for all people, hibernate, seam and all xa drivers.  I will attach logs of postgres xa driver and oracle one but basically they are trying to open a connection to database when ANY http request comes in until waiting to see if we actually do any select statements or updates or inserts.  For some reason, the postgres driver and oracle driver where fine here...they did not make db requests when an http request came in.  The oracle driver however did make a request to the db when commit is called even if no sql was done against the db where postgres driver ignored the commit since no sql was done.  I will try to attach files or more comments here.  PLEASE if you report a tic in hibernate put it in here for others to find when they hit this issue.

keyphrases:
seam doesn't work when database goes down
seam infinite redirect on db outage
database failure causes seam to not work
