/usr/bin/jvncviewer其实主要就是 /usr/share/vnc-java 这个目录了，里面的 class 文件就是 applet 需要的东西，vnc 文件是一套模板。怎么用这个东西呢？
/usr/share/java/vncviewer-3.3.3r2.jar
/usr/share/vnc-java
/usr/share/vnc-java/animatedMemoryImageSource.class
/usr/share/vnc-java/authenticationPanel.class
/usr/share/vnc-java/clipboardFrame.class
/usr/share/vnc-java/DesCipher.class
/usr/share/vnc-java/optionsFrame.class
/usr/share/vnc-java/rfbProto.class
/usr/share/vnc-java/vncCanvas.class
/usr/share/vnc-java/vncviewer.class
/usr/share/vnc-java/hextile.vnc
/usr/share/vnc-java/index.vnc
/usr/share/vnc-java/noshared.vnc
/usr/share/vnc-java/shared.vnc
/usr/share/vnc-java/tight.vnc
/usr/share/vnc-java/zlib.vnc
/usr/share/man/man1/jvncviewer.1.gz
/usr/share/java/vncviewer.jar
/usr/share/vnc-java/vncviewer.jar
比如我们把上面文件放在 ~/vnc-html 里面，则可以如下调用 vncserver，
$ vncserver :1 -geometry 640x480 -depth 16 -httpd ~/vnc-html -httpPort 5678这样，将在本地 5678 端口建立一个 mini http 的服务器（Xvnc 这个进程负责），并用 vnc 文件作为模板生成页面（上面含有 java applet）。这样在浏览器上输入 http://ur-ip-or-url:5678 即可打开该页面，如果你的浏览器支持 java applet（现在使用的 jre 1.5 可以正常浏览，但是 1.6 不行），就应该看到登录界面了。
那么这是什么原理呢？是否可以用一个一般性的 http 服务器实现这个过程呢？那么我们来看看上面那些 vnc 文件都有些什么吧！
<!-- index.vnc - default html page for Java VNC viewer applet. On any file注意，其中一些 $ 开始的是关于 VNC server 的一些参数，由 Xvnc 运行时替换。这样我们不难知道，实现一般 http server 的方式就是将这些对应的页面放在 http server 的合适目录下面，然后将这些 vnc 文件通过某种方式变成 html（估计写个 sed 或者直接 shell 就可以替换掉这些东西了）。
ending in .vnc, the HTTP server embedded in Xvnc will substitute the
following variables when preceded by a dollar: USER, DESKTOP, DISPLAY,
APPLETWIDTH, APPLETHEIGHT, WIDTH, HEIGHT, PORT. Use two dollar signs
($$) to get a dollar sign in the generated html. -->
<HTML>
<TITLE>
$USER's $DESKTOP desktop ($DISPLAY)
</TITLE>
<APPLET CODE=vncviewer.class ARCHIVE=vncviewer.jar
WIDTH=$APPLETWIDTH HEIGHT=$APPLETHEIGHT>
<param name=PORT value=$PORT>
</APPLET>
<A href="http://www.tightvnc.com/">www.TightVNC.com</A>
</HTML>
但是这个 applet 必须直接能访问到 vnc server，如果中间被防火墙隔开了，也就没有用了。
