Looks like your container is attempting to serialize/deserialize
Do those classes implement Serializable?
(also..keep in mind A no-arg constructor must be accessible to any subclass
that is serializable.)

Subject: Tomcat 5.5 and Connection Pooling
Hello,
I'm trying to set up connection pooling for Tomcat 5.5 but it
doesn't work. When I start Tomcat, it shows in the Catalina log this:

My java code shows the error message that it "Cannot create JDBC driver
of
class 'sun.jdbc.odbc.JdbcOdbcDriver'" for my ODBC alias.
Any help would be appreciated.
Thanks,
Mike
