What versions of each have you been using? (apache tomcat) and what distribution
and linux kernal are you running? What jvm? I would love to have the success
you're having and really like tomcat when it's working for me.
p.s. My jsp back into rmi services so the reason for failure isn't connected to
the database or services as they both run through multiple tomcat deaths and
re-starts.
