Servlet Loading (Beta)
Contents / Settings /
Procedures / Buttons
The Servlet Loading page allows you to enter, edit, or delete servlet loading
information for local or remote servlets. After you've loaded a servlet, you can
invoke it whenever you want to by:
- calling it directly using a URL.
- embedding it in a server-side include statement inside an HTML document.
- loading it automatically when the Java Server starts up, then calling it
by means of a URL or server-side include.
Settings
The Servlet Loading page has the following two options:
Add a New Servlet
Allows you to add a new servlet to the list of servlets to be invoked.
To add a new servlet:
- Servlet Name - Enter the unique name of the servlet you are adding.
- Servlet Class - Enter the name of the Java class for the servlet.
This consists of the package name without the ".class" extension.
For example, "sun.server.http.FileServlet" is a valid class name.
Configure a Servlet
Allows you to define when the servlet is invoked, if it is a remote or
local servlet, and other information. For each servlet in the Servlets
Configure list, Java Server displays the following information:
- Name - The unique name of the servlet.
- Description - A text string describing the servlet. This field is
sometimes blank.
- Class Name - The name of the associated class file for the servlet.
- Arguments - The servlet argument list, where each argument is in the
form "name=value".
- Load at Startup - Whether or not Java Server loads the servlet when
the server starts.
- Load Remotely - Whether or not Java Server loads the servlet from a
remote location.
- Class File URL - The URL that points to the class file for the remote
servlet.
To Enter Information for a Servlet:
- In the Name field of the Add a New Servlet screen, enter a unique
name for the servlet.
- In the Class Name field of the Add a New Servlet screen, enter the
servlet's class name, which consists of the package name without
the ".class" extension. For example, "sun.server.http.FileServlet" is a
valid class name.
- In the Argument field of the Configure a Servlet screen, enter
comma-separated "name=value" pairs.
- To load the servlet when the server starts, click Yes.
(By default, servlets are only loaded when you activate them.)
- Click Save.
If the servlet is a remote servlet, do the following step in addition to
doing the above:
- In the Class Location field, enter the full URL, ending with a slash, of
the servlet's class file on the remote server. For example, if
HelloWorld.class
exists on a remote Java Server named
nightsky.com
in the top level public_html
directory,
then the URL is http://nightsky.com/
.
Procedures
To Delete Information for a Servlet:
- Select the entry that you want to delete.
- Click Delete.
To Edit a Servlet Entry:
- Select the entry.
- Delete the entry.
- Reenter the entry.
- Click Save.
Buttons
To make changes to the Servlet Loading page and have those settings
take affect, use the three buttons at the bottom of the screen. These
are:
- Save - Writes your changes to the Java Server and changes
the settings.
- Revert - Takes you back to the previous settings for all
fields in the screen. Use this button to undo changes you have not yet
saved.
- Remove - Removes the servlet from the servlet list.
