[Thomas Bosch (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBAS-5282?page=all ]

Thomas Bosch updated JBAS-5282:
-------------------------------

    Fix Version/s:     (was: JBossAS-4.0.4.CR2)
      Description: 
When redeploying a .ear or .war containing .jsps, there are many situations causing a .jsp that needs to be recompiled to not be recompiled, or to be recompiled continuously.  

Any situation causing the timestamp of the modified .jsp to be older than the timestamp of its compiled class will cause it not to be recompiled; for example:
- reverting to a previous version of the .jsp using a version control
- timezone difference between development and production server
- .jsp never visited in production server until after change is made, which can happen for a rarely visited page, or a newly deployed server.

- .jsp never visited in production server until after change is made, which can happen for a rarely visited page, or a newly deployed server.

Continuous recompilation happens in any situation causing the timestamp of the modified .jsp to be newer than the current time, and will happen until current time catches up; for example:
- timezone difference between development and production server
- future time assigned to .jsp
