Please, how should I interpret the exception message header below:
javax.naming.NoInitialContextException: Need to specify class name in
environment or system property, or as an applet parameter, or in an
application resource file: java.naming.factory.initial
I'm using jdk1.4.1 (SUN) and tomcat 3.2.4.
thanks,
Pedro Salazar.
