Subject RE: how to load a property file in tomcat4.1.24???
Date Tue, 13 May 2003 13:17:27 GMT

Howdy,
RTFM:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html

Or search the archives.

WEB-INF/classes is automatically on the "classpath" for your webapp and
JSP.  You don't need to modify the classpath environment variable nor
any of the classpaths in tomcat's startup scripts.
