Below are some known problems with Roller 4.0 (each verified by a Roller committer), that you should be aware of. You can also find bugs reported against 4.0 in our JIRA issue tracker.

• If you're deploying Roller on Geronimo or JBoss, and you're using roller-custom.properties to configure your database, you'll need to comment out the <resource-ref> elements at the bottom of Roller's web.xml file.

• If you want to use Roller's Planet aggregator feature, then refer to the Installation Guide section 9, page 14. Due to some problems (see ROL-1664) in the Planet configuration and documentation, you'll need to create also want to pay attention to these additional steps:
  • Create a planet-custom.properties file to contain the Planet configuration properties. You must include
  the very
  • these things in the properties file:
    • The same database
  configuration
  • • properties that you included in your roller-custom.properties
  file
  • • .
    • Set the 'cache.dir' property to point to your Planet Cache directory.
  • In STEP 2, the correct name for the task is RefreshRollerPlanetTask.
  • Since we put the PlanetModel in the 'rendering.siteModels' list, Planet will only work in the Front Page blog of the website and the front-page blog must by setup as an "aggregated site-wide front page." See the Server Admin->Configuration page to set this up.
