I'm pretty certain that my war file is set up correctly. In my
WEB-INF/lib directoy I have jdbc jar file that tomcat can't find and the
tomcat user manual for deploying tomcat applications says
WEB-INF/lib/ - This directory contains JAR files that contain Java
class files (and associated resources) required for your
application, such as third party class libraries or JDBC drivers.
My servlets are in the WEB-INF/classes directory and the same document
says
WEB-INF/classes/ - This directory contains any Java class files (and
associated resources) required for your application, including both
servlet and non-servlet classes, that are not combined into JAR
files.
Aside from that I have read the Servlet 2.3 spec on this topic and it
says this about the WEB-INF/lib
The /WEB-INF/lib/*.jar area for Java ARchive files. These files
contain servlets, beans, and other utility classes useful to the web
application. The web application class loader can load class from
any of these archive files.
Here is what it says about the WEB-INF/classes directory
The /WEB-INF/classes/* directory for servlet and utility classes.
The classes in this directory are available to the application class
loader.
Now to re-cap I have a jdbc jar file in WEB-INF/lib and I'm trying to
access it from a servlet in WEB-INF/classes
After looking at the spec again it says the container "can load
classes from any of these archive files". I suppose this could mean
that it is optional for the container to load the classes found in
this directory, in which case tomcat is adhearing to the spec and it
is not required to load all the classes it finds there.
If you see something that I'm mis-interpting please let me know.
thanks
joe
