New TightVNC Java Viewer 2.1 — Improved Compatibility and Adjustable Color Depth
January 27, 2012 — GlavSoft company has released version 2.1 of
TightVNC Java Viewer, its free cross-platform remote control client. New version:
- fixes compatibility with Apple Remote Desktop,
- allows to adjust traffic requirements by selecting an appropriate color depth, from 3 to
24 bits per pixel,
- includes a bunch of minor improvements, fixes and cleanups.
The core component of the Viewer is able to handle all color depths as allowed by the
RFB protocol, giving new level of flexibility to the developers using our components in their

What Is TightVNC Java Viewer? — the "Run-Anywhere" Remote Control Client
It's a fully-functional remote control program written entirely in Java. It can work on
any computer where Java is installed. That can be Windows or Mac OS, Linux or Solaris
— it does not make any difference. And it can work in your browser as well.
- It connects to another computer and displays its live remote desktop.
- It lets you control the remote computer with your mouse and keyboard, just like you
would do it sitting in the front of that computer.
It requires that the remote computer is running any type of VNC-compatible server software
(standard VNC, TightVNC, UltraVNC, x11vnc, Apple Remote Desktop in Mac OS X, Xen/HVM, VMWare,
Qemu etc.). For Windows systems, TightVNC Server is a recommended option.
Why Java? What Are the Benefits?
- It can run on any hardware, under any operating system with Java installed.
- It's nearly as fast as the native version (our tests show it can be faster in
- It can be easily integrated with Web sites and Web-based services.
Finally, it can be used not only as a normal standalone application, but also as a
Web applet! That means users can access their desktops from any computer with
any Java-enabled Web browser, without installing any software on the client

More Details on Licensing: Free and Commercial
Just like TightVNC Server version 2 for Windows, it is available either as
free software (GNU GPL license) or commercially. Commercial
license is required if you would like to use TightVNC Java Viewer or its components in your
proprietary programs or scripts. Also, it may be a reasonable option if the GNU GPL license
is not acceptable for some other reasons.
What's New, in Detail?
Here is the list of changes in version 2.1, as compared to 2.0.95:
- Corrected negotiation of the protocol version. There was an error which made TightVNC
Java Viewer incompatible with Apple Screen Sharing (built-in VNC-compatible server in Mac OS
X). New version should be able to connect to Mac OS X.
- Added support for various color modes. You can restrict the number of colors to save
traffic, or prefer a rich-color format to maximize image quality. From the GUI, you can
choose a color mode with 8, 64, 256, 65536, 16777216 colors, or select the server's
native number of colors. However, the core component supports any color format as allowed by
the RFB protocol (except palette-based modes).
- Various minor improvements, fixes and cleanups.
What Was New in Version 2.0? — Almost Everything!
Version 2 of the Viewer was designed and written from the scratch. Our primary goal was to
eliminate numerous problems of previous versions, and we think we have reached the goal.
As compared to previous versions, Version 2 is faster and more stable, uses
Swing-based user interface and should be perfectly compatible with modern Java
environments. New source code features improved design, component-based architecture and high
code quality — it should be far easier to integrate new viewer with other Java
Finally, version 2 is available both as free software and under a business-friendly license, while previous versions were strictly
The nearest version of the viewer will include desktop scaling. Then, expect built-in SSH
tunneling, file transfers, and major usability improvements.
