Deploy a Servlet

The deployment descriptor is used to customize other servlet parameters such as:

•

Initializing Servlets on page 3-13.

•

Preloading Servlets on page 3-11.

•

Defining a Session Timeout Value on page 3-12.

•

MIME Mapping. The HTTP protocol uses Multipurpose Internet Mail Extensions

(MIME) types for describing content. When a webserver sends a document to a

client, the server should include a section in the response to indicate the type of

document so the browser can render the document correctly. Most browsers can

guess the type from the extension, for example doc, pdf, or gif, but it is good

programming practice to include a definition in the deployment descriptor.

This is not necessary for dynamic content where the servlet generating the

response should specify the MIME type using setContentType() on the

HttpServletResponse object, but it is useful to define the MIME types for your

static content in the public area of the web application.

Default MIME types are provided in the mime-types.config file in the conf

directory (the default is /usr/tandem/webserver/conf). You may add to that

file. If you do, you must also add those MIME types in the global web.xml file in

the $NSJSP_HOME/conf directory.

Example 3-11. Deploying a Servlet

<web-app>

<servlet-name>start<servlet-name>

<!-- the fully qualified servlet class name -- >

<servlet-class>startCartRequest</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>start</servlet-name>

<url-pattern>/myapp1/*</url-pattern>

</servlet-mapping>

</web-app>

Example 3-12. How to Set the MIME Type

<web-app>

<mime-mapping>

<mime-type>application/msword</mime-type>

</mime-mapping>

</web-app>
