I am migrating my application from Apache-Tomcat with Oracle DataBase to JBoss with MySQL Data base.. I added the MySQL driver (connector/j) in the lib directory of default server. The apllication otherwise runs fine except the DataBase connectivity part... When trying to access a page that requires DataBase connectivity.. The page goes blank.. I checked the server log.. It said that the required Database.table did not exist... but when I checked using the normal SQL command on the server.. It was there..... What could be the problem... Is there any configuration setting that I have overlooked??
