Attempting planet startup debugging

[Eric Wittle <er...@wittle.net>]

OK, in the absence of more specific suggestions, I tried to turn on  
debug logging for most of the interesting classes I could find in  
roller-planet-business.jar. Specifically, I added the following to  
both roller-custom.properties and planet-custom.properties:

# Planet Debugging
log4j.category.org.apache.roller.planet.business.Manager=DEBUG
log4j.category.org.apache.roller.planet.business.PlanetFactory=DEBUG
log4j.category.org.apache.roller.planet.business.PlanetManager=DEBUG
log4j.category.org.apache.roller.planet.business.PlanetProvider=DEBUG
log4j 
.category.org.apache.roller.planet.business.startup.PlanetStartup=DEBUG
log4j 
.category 
.org 
.apache.roller.weblogger.ui.rendering.servlets.PlanetFeedServlet=DEBUG

I then cleaned out the log files and restarted. No error message or  
additional debug messages were apparent. When I browsed to the planet  
RSS feed URL, I got the same exception, and maybe one debug statement.  
The relevant snippet of the log is:

INFO  2008-02-26 17:44:14,288 PlanetFeedServlet:init - Initializing  
PlanetRssServlet
INFO  2008-02-26 17:44:14,289 PlanetCache:<init> - Planet cache =  
{id=cache.planet, enabled=true, timeout=1800, size=10}

ERROR 2008-02-26 17:44:20,438 StandardWrapperValve:invoke -  
Servlet.service() for servlet PlanetFeedServlet threw exception
java.lang.IllegalStateException: Roller Planet has not been  
bootstrapped yet

So I'm still at a loss about what to look at next. Exactly what class  
is responsible for "bootstrapping" roller planet, and should I expect  
that debug logging will be helpful in telling me what is wrong?

I'm still betting it is data in my Roller database. Are there log  
levels that will let me see the SQL queries it is generating? I  
suppose I could turn on SQL logging in MySQL...

bootstrapping the planet backend happens in the 
RollerContext.contextInitialized method, just like with the weblogger 
backend.  Both of the planet and weblogger backends run through the same 
steps ... prepare (test for core services like db connection), bootstrap 
(wire up backend classes), and initialize (a chance for objects to do 
initialization work that must happen after bootstrapping).

I'm not sure exactly what your problem is, but the planet backend 
provides INFO level logging about its bootstrapping progress, so if you 
think it's not bootstrapping properly it should show you without having 
to mess with DEBUG logging.
