The simple and elegant look of the < oXygen/ > combined with the complete coverage of the XML editing features have made it popular in both the corporate and academic worlds.

oXygen XML Editor provides the necessary tools for the document creation and presentation.

The documents can be created and validated against any user defined schema. The smart context sensitive editing saves time and guarantees a minimum number of validation errors.

The documents can be published in a wide range of formats including HTML, PDF, PostScript using the built-in or external processors.

Developers can use < oXygen/ > for authoring document schemas and for editing and debugging the XSL stylesheets needed for the presentation layer. The integration with the document repositories is made through the WebDAV and FTP protocols.

Installation:

After downloading open a shell and, cd to the directory where you downloaded the installer.
Make sure you have in your PATH environment variable the correct location of the JRE. Also, make sure that older JREs (like 1.0.6) are not listed in PATH.
At the prompt type: sh ./oxygen.bin.
On some Linux distributions (including RedHat), the installer stops with the error:
Warning: -Xmx50331648 not understood. Ignoring. Warning: -Xms16777216 not understood. Ignoring. Exception in thread "main" java.lang.NoClassDefFoundError: com.zerog.lax.LAX - This is caused by the fact that there is installed an older Java VM in the /usr/bin directory (version 1.1.x). The installer uses this by default and is unable to launch. You can rename the file (/usr/bin/java to java.old) and try again the installer. You must have the correct java executable (version 1.4 (recommended) or 1.5) in your PATH environment variable.
Other solution is to download and install the "All platforms" distribution, see installation instructions bellow.
