You can get freely from SUN the adapted Java version for your computer :
and for MacIntosh
http://support.apple.com/downloads/
Under LINUX (or Unix) you download the compressed file jaPreTeX.zip and you unzip it in your "home" directory. This create a directory jaPreTeX which has, as a sub directory among others, the directory
"jaPreDocs". You open it and there you double-click on the executable "jarPret". jPreTeX opens now on a new document.
Of course you can create an alias on the desk and put on it the icone "asterix.png" which is in the directory jaPreTeX.
Under WINDOWS, you download the compressed file jaPreTeX.zip and you unzip it in in your "home" directory : "C:\Documents and Settings\Your Name". (Attention NOT in C:\Documents and Settings\Your Name\jaPreTeX even if it is a proposition of the unzipper !)
This create a directory jaPreTeX which has, as a sub directory among others, the directory
"jaPreDocs". You open it and there you double-click on the executable "jarPret.bat". jPreTeX opens now on a new document.
Of course you can create an alias on the desk and put on it the icone "asterix.ico" which is in the directory jaPreTeX.
For MACINTOSH, you download the compressed file jaPreTeX.zip and you unzip it in your "home".
This create a directory jaPreTeX which has, as a sub directory, among others, the directory
"jaPreDocs". You open it and there you double-click on the executable "macPre.app". jPreTeX opens now on a new document.
Of course you can create an alias by clicking with the right button of the mouse on "macPre.app" and put the alias on the desk.
Be careful :The jPreTeX documentation is now contextual.
Bye-Bye.
