Configuring Servlets in the Default Virtual Server

Chapter 8 Legacy Servlet and JSP Configuration 83

Registering Individual Servlets

The iPlanet Web Server treats any file in a registered servlet directory as a servlet.

There is no need to register individual servlets that reside in these directories

unless any of the following criteria apply:

• The servlet takes input parameters that are not passed through the request

URL.

• You want to set up additional virtual URLs for the servlet.

• Your servlets are packaged or in a

.jar file. The server does not search .class

.jar files for packaged servlets.

If any of these conditions is true, register the individual servlet by using the Legacy

Servlets>Configure Servlet Attributes page in the Server Manager interface.

Alternatively, you can edit the file

servlets.properties to add an entry for the

servlet.

When registering an individual servlet, specify the following attributes:

• Servlet Name -- The iPlanet Web Server uses this value as a servlet identifier to

internally identify the servlet. (This identifier is not part of the URL that is used

to invoke the servlet, unless by coincidence the identifier is the same as the

class code name.)

• Servlet Code (class name) -- the name of the class file. You do not need to

specify the

.class extension.

• Servlet Classpath -- This is the absolute pathname or URL to the directory or

zip/jar file containing the servlet. The classpath can point anywhere in the file

system. The servlet classpath may contain a directory, a

.jar or .zip file, or a

URL to a directory. (You cannot specify a URL as a classpath for a zip or jar

file.)

If the servlet classpath is not a registered servlet directory, you must

additionally provide a servlet virtual path for it (as discussed in “Specifying

Servlet Virtual Paths,” on page 84) to make the servlet accessible to clients.

iPlanet Web Server supports the specification of multiple directories, jars, zips,

and URLs in the servlet classpath.

• Servlet Args -- a comma delimited list of additional arguments for the servlet if

required.

The following code shows an example of the configuration information for the

same servlet in

servlets.properties:

1 2 ... 78 79 80 81 82 83 84 85 86 87 88 ... 123 124
