RE: The purpose of WEB-INF\classes ?
Hi, WEB-INF/classes takes precedence over WEB-INF/lib in the servlet spec: 2.3fcs, section SRV.9.5 Directory Structure. If WebLogic 6.1 behaves differently then it's another spec violation ;) WL6.1 is Servlet Specification 2.2-compliant, not 2.3. I think that loading order may have been a clarification in 2.3, though always intended to be this way, so tomcat is (and has always been) correctly implemented in this regard.

RE: The purpose of WEB-INF\classes ?
Just for historical accuracy (not that anyone cares)... ;) I looked back at the 2.2 spec and, as Yoav mentioned, it doesn't say anything about class loading order from the /classes and /lib directories. Although WL61 is 2.3 non-final compliant, apparently the ordering clarification didn't make it into that release. justin At 05:58 AM 3/2/2004, you wrote: Hi, WEB-INF/classes takes precedence over WEB-INF/lib in the servlet spec: 2.3fcs, section SRV.9.5 Directory Structure.

The purpose of WEB-INF\classes ?

RE: The purpose of WEB-INF\classes ?
The first reason I can think of is configuration files. I have one environment on my development box, another on the test deployment box and yet another on the final production server. Depending on the box I'm on I'm going to use different database URLs at a minimum and quite often I'm having to use different directories for temporary/permanent files depending on whether I'm on windows or unix. If I put those configure files into jar files I'd have to unjar the jars, change the files and then rejar the files again. It's much easier to leave those out of the jar files and have them in the classes folder where you can just go and edit them. --mikej -=-- mike jackson [EMAIL PROTECTED] -Original Message- From: news [mailto:[EMAIL PROTECTED] On Behalf Of George Hester Sent: Monday, March 01, 2004 5:46 PM To: [EMAIL PROTECTED] Subject: The purpose of WEB-INF\classes ?
