Java Servlets and JavaServerPages (JSP)
272 Netscape Enterprise Server Administrator’s Guide
Making Servlets Available to Clients
You can install JSP files simply by putting them in any directory in or under the
document root—you do not need to do anything special to install JSP files—so
long as the following conditions are true:
• The Enterprise Server has been instructed to use the JDK.
• Both servlets and JSP are enabled in the server.
For servlets, you have a choice of two ways to make a servlet accessible to
clients:
• Put the servlet class file in a directory that has been registered with the
Enterprise Server as a servlet directory. For more information, see
“Specifying Servlet Directories.”
• Define a servlet virtual path translation for the servlet. In this case, the
servlet class can be located anywhere in the file system or even reside on a
remote machine. For more information, see “Configuring Servlet Virtual
Path Translations,” on page 275.
Specifying Servlet Directories
One of the ways to make a servlet accessible to clients is to put it into a
directory that has been registered with the Enterprise Server as a servlet
directory. Servlets in registered servlet directories are dynamically loaded when
needed. The server monitors the servlet files and automatically reloads them on
the fly as they change.
For example, if the
SimpleServlet.class
servlet is in the
servlet
subdirectory of the server’s document root directory, you can invoke the servlet
by pointing the web browser to:
http:// your_server/servlet/SimpleServlet
You can register any number of servlet directories for the Enterprise Server.
Initially, the web server has a single servlet directory per server instance, which
is
server_id/docs/servlet/
.
