Benoit,

Thanks for the response. I did try re-compiling and this changed
nothing.

A bit more info though:

1. When I first tried this, only the servlet's class file
(TestServlet.class) was placed under the www/servlet directory of
jigsaw. I left the supporting classes (PoolObject.class and 
ResultCodes.class) elsewhere (but still on the classpath specified to
java when running the server). This resulted in the access error I
originally mentioned.

2. So I tried moving all of the files (servlet as well as support class
files) into their respective directories all located under the
www/servlet directory. When I do this, the access error is NOT
encountered. I find this odd.

3. I am not sure if the following is a result of my browsing the servlet
directory using jigadmin but I believe so. I do see the following
messages displayed on jigsaw's console:

	Create Servlet : PoolObject.class
	Create Servlet : ResultCodes.class

These files are support classes rather than servlet classes. In
jigadmin, I see no servlet wrappers created for these despite the
messages on the console. Perhaps this is just an attempt by the servlet
indexer to create servlet wrappers which ultimately fails (because they
are not servlets)?

Cheers,

David
