No, it's not. It's code that defines an interface and a poorly
implemented exception type. There's no catching. Anywhere.

Other than including Tomcat in the subject, this has nothing to do with
Tomcat. No offense, but this really isn't a list for teaching Java.
But what the hell, I'll make one "exception":
public class DAOException extends Exception {
public DAOException(String msg) {
super();
}
public DAOException(String msg) {
super(msg);
}
public DAOException(String msg, Throwable cause) {
super(msg, cause);
}
public DAOException(Throwable cause) {
super(cause);
}
}
That's all I'll say on this thread.
