I had not thought of that, and you're right (literally technically speaking). RAMBLE: However, if I try to look at it from a point of view of a large bureaucracy, of which I am largely ignorant, I would not be surprised if there is a policy against dev kits and IDE's on production servers for security sake. Tomcat (whisper: with built-in compiler) is approved, but is the JDK allowed? Guess I can ask. Yeah, it's potentially a "distinction without a difference". Well, unless there are other tools in the JDK that can pose security risks in addition to the Java compiler. mt> OpenJDK is very close to the Oracle JDK these days.

Meh, not my call. Whatever the Powers That Be decide for the production environment, I'll probably match that in dev. If they decide LT$ is the way to go, using the JDK will cost nothing for my dev environment anyway. But if OpenJDK and frequent updates are selected ... phooey. -- Cris Berneburg CACI Lead Software Engineer --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
