WiredX

WiredX is an X Window System server, written in pure Java™.
WiredX enables you to access UNIX/X applications from all web browsers with Java2 Plug-in, and WiredX-Lite enables you to access UNIX/X applications from web browsers(without Java Plug-in) such as IE and Netscape. They are available at WiredX.Net.

Features

• WiredX is written in pure Java.
  Its byte-codes measure about 200KBytes in JAR format.
• WiredX depends on Java2(JDK1.2).
• WiredX accepts X window protocols(X11R6.3) directly.
• WiredX doesn't need a proxy program.
  Some Javanized X servers already exist. They, however, need a proxy program, which translates X protocols to their own proprietary protocols.
• Copy & Paste operations between WiredX and the native window system are supported.
• XDMCP and REXEC are supported.
• Anti-aliased text is supported.
