I have a webapp running under tomcat 5.5 with no problem.
When I try to run my webapp with tomcat 6.0, I have an classnotfound error for
the mysql driver.
Of course, i have try to put the mysql driver jar file in /tomcat 6/lib folder,
in my webapp web-inf/lib folder, in both folders... I always have this error
with tomcat 6.
But it works perfect with tomcat 5.5...
Here is the error :
