Sorry for the delay. I tried to login and give you the log but the site was down. Anyway, in the meantime, I went searching for the solution based on the error message in error.log. The error was “Caused by: java.lang.NullPointerException”. Found a site that pointed to my settings.xml file being corrupted. So, I deleted the spark folder from my documents and settings. This solved the problem and I am now able to login. Just for kicks, below is the error.log. And the site that I found the solution at is: http://eval.jivesoftware.com/forums/thread.jspa?threadID=21128&tstart=425. I appreciate your help in pointing me to the log file.
