Chapter 11, Extending Your Server With Programs 273
Java Servlets and JavaServerPages (JSP)
The Enterprise Server expects all files in a registered servlet directory to be
servlets. Any files, including applets, in that directory that have the
.class
extension will be treated as servlets. The Enterprise Server does not correctly
serve other files, such as HTML files or JSPs, that reside in that directory.
The server can have multiple servlet directories, all of which must reside below
the primary document directory in the directory hierarchy. You can map servlet
directories to virtual directories if desired. For example, you could specify that
http://poppy.my_domain.com/products/
invokes servlets in the directory
server_id/docs/servlet/january/products/servlets/
.
To register servlet directories and to specify their URL prefixes (virtual or not),
use the Servlet Directory page in the Servlets tab of the Server Manager. Set the
following fields:
URL Prefix. The prefix for accessing the directory. For example, if you want
the logical URL
http:// servername /plans
to translate to the directory
d:/netscape/es40/docs/plans
then enter
plans
in the URL Prefix field.
Servlet Directory. The absolute pathname to the directory to be registered as
a servlet directory, for example,
d:/netscape/es40/docs/plans
. The
Enterprise Server treats all files in the directory as servlets.
Note
By default, URLs that are redirected are always escaped. To prevent this, add
escape="no"
.
F
or example:
NameTrans fn="redirect" from="/foobar" url-prefix="index.html" escape="no"
Configuring Global Attributes
You can set some global attributes for servlets, including:
• Servlets to run when the server starts up.
• The Session Manager to be used by servlets.
• The amount of time the server waits before reloading servlets if they have
changed.
To set the global attributes, use the “Configure Global Servlet Attributes” page
in the Servlets tab of the Server Manager. Set the following fields:
