Subject Tomcat 5.5 question
Date Thu, 29 May 2008 14:23:42 GMT
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
