David, I think I am a little confused. Someone else on this list suggested that I go back to my JDBC driver vendor, and/or my JSP/Servlet vendor and find out what jar file their implementation of JNDI was located in, and to get advice on how to set properties and obtain a new Initial Context. I did get a reply from my JDBC vendor, who indicated that their sample file used the com.sun.jndi.fscontext.RefFSContextFactory by default, since this was included in the Sun JDK. Since I could not get either the Java class or my Servlet file working, I suspect that I don't have something set up on my dev box properly, perhaps the fscontext jar file, as you suggested. But my intent is to actually use JNDI in a servlet. My driver vendor suggested that if I wanted to use JNDI inside my JSP/servlet server environment, I would need to contact the vendor of my servlet server (Allaire in this case) and find out what jar file and API they had for setting properties and creating a new Initial Context. I am still waiting to here back from Allaire. Am I on the right track here, or am I completely missing something???
Thanks in advance for your advice/input. Celeste -----Original Message----- From: David M.

This particular class (as I recognize it) should be in the "fscontext.jar" that is part of the "File System" sample JNDI service provider that you can get from <http://java.sun.com/products/jndi/serviceproviders.html>. -- =================================================================== David M.
