Installation and Execution

Download finger.zip.
Extract finger.jar from the zip file.
Install Java on your computer if you do not already have it.
If you are using Java 1.1 instead of Java 1.2, include the location of the downloaded JAR file in your CLASSPATH environment variable.
Example:
```
     set classpath=%classpath%;J:\lib\finger.jar

     
```

To run as system command line prompt utility, run


     java -jar finger.jar

if you have Java 1.2 or


     java org.anser.proj.timc.prog.croft.app.finger.FingerFrame

if you have Java 1.1.

You may wish to use a DOS batch file or Unix script.
Example DOS batch files (finger.bat):


java -jar finger.jar %1


java org.anser.proj.timc.prog.croft.app.finger.FingerFrame %1

To run as a GUI application, run the program without the e-mail address argument. You will be prompted with a window.
To run the program as an applet, use an HTML page such as this:
```
<HTML>

<HEAD>

<TITLE>

Finger

</TITLE>

</HEAD>

<BODY>

<CENTER>

<APPLET

  ARCHIVE="finger.jar"

  CODE="org.anser.proj.timc.prog.croft.app.finger.FingerApplet.class"

  WIDTH=640

  HEIGHT=480

>

A Java applet would be here.

</APPLET>

</CENTER>

</BODY>

</HTML>

     
```
Note that this may not work due to applet security restrictions when attempting to finger an e-mail address other than those on the same server as the applet host.
The applet is available on this server for testing: FingerApplet.
To run the program as a servlet, load the class org.anser.proj.timc.prog.croft.app.finger.FingerServlet.
The servlet is available on this server for testing: FingerServlet.

Usage

Note that not all servers and user provide finger information. This information is available on a strictly voluntary basis. Typically, users can edit the information available on a Unix system by modifying a file in their home directory.

If your Internet connection is down, "Unknown host error: server not found" may be displayed.
