but,when I run my program,there is an exception:
19:42:56,984 WARN SettingsFactory:95 - Could not obtain connection metadata
java.sql.SQLException: Cannot load JDBC driver class 'null'


why?

my database is mysql4.0.13
driver is mysql-connector-java-3.0.11-stable-bin.jar
JDK1.4

hello~~
can everybody help me?

Mmm, as this is a tomcat configuration issue, I'm sure some one on the tomcat list would be able to help you sort this out. Sorry I don't have much experience with Tomcat setup.
