tomcat and jdbc connector 2007-10-01 - By David Smith

I doubt this is tomcat's fault in any way given the code snippet is pure
java and doesn't access the api except for the success message. Can you
verify the Ubuntu machine really has access to the MS SQL server (no
firewall on either system)? Also I'm guessing you also verified the
version of Java on that system is really Sun's JVM and not some variant
like GNU Java or Kava.

tried the same project with this jsp to a different computer on the same
network that has Tomcat 6 as well(only that computer runs on Ubuntu, mine on
win xp). And on that computer I get
