Hi all I am getting a weird FileNotFoundException once in a while... i am using jboss-2.2 + tomcat (downloaded the bundle from the web site ). I am also InstantDB, that comes with the package. This error occurs very rarely, and i am unable to reproduce the error. Can anybody throw some light on the cause for this error. I have cut and paste the console output......
