Subject Re: exception while viewing the blog
Date Tue, 26 Apr 2011 11:46:25 GMT
This part of the stack-trace is the important part:

SEVERE: Servlet.service() for servlet PageServlet threw exception
java.lang.NullPointerException at
org.apache.roller.weblogger.config.WebloggerRuntimeConfig.isFrontPageWeblog(WebloggerRuntimeConfig.java:226)

I bet this is an Oracle-specific problem. You might be able to work
around it by setting a Front Page blog if you have not already done so
(via the Server Admin page).

You might want to try the Roller 5.0 RC6 build to make sure this
problem is fixed in Roller 5.
