This could have happened for lots of reasons. You'll to check your log files to see if you got any exceptions or anything like that. Specifically, check your application's log file (if you are using log4j or anything like that), then the context log created by Tomcat (usually called either [your-app].log or localhost.log), and then the standard output log (catalina.out). Hope that helps, -chris
