I am Sys Admin so won't know about app itself but here is my env
OS: Ubuntu 10.4
Tomcat Ver: 6.0.24
Apache: Ver 2
JDBC Driver: 5.1.18 copied in /var/lib/tomcat6/lib/
App works just fine. Issue is that when I reboot server and access app the first attempt always fails
catalina.out shows bunch of JDBC driver errors "No suitable drive found"
If I try same app again second time it starts working fine with no error. No JDBC error, all good
What is wrong? I have tried restarting tomcat after server reboot is complete. If I undeploy app and deploy it again then it does not work at all because undeploy make JDBC drive to de-register and it does not register again unless tomcat is restarted.
