Running tomcat from CD-ROM

[Wolfgang Egger <be...@wolfgang-egger.de>]

Servus,

I have to develop a project, that must be platform independant and has to run
within a browser. The project must be shipped on CD and there must no
installation or setup procedure.

Because there has to be some computations and user-interaction at runtime, I 
have to access some files on the CD and because I don't want to do all that 
with JavaScript, my idea is to start tomcat from the CD and do all the 
computational stuff with java.

I assume it's possible to decide on which platform the app is running, so I
ask, if it is possible to start the right (for the current OS) tomcat with
the right java from the CD? Or does tomcat has to have write-access to the
place where it is startet from, e.g. for logging and other things it has to
write at runtime?

Have a nice and peacefully day!

Wolfgang

As automatic as possible;-)

Yes, I hope I can talk with the customers that this should be the way we go. 
The concept says, that there should be some autostart-action when putting the 
CD into the CD-player, but I don't think, that I will find a solution doing 
that for all platforms with the same procedure, so I hope I could let the 
user make the choice. In real life 98% of the possible users have MS Windows 
running, so may be we only promote the windows-cd-autostart and let the other 
users starting the system manually.

No problem! I'm happy to have some days to think about all of that, without 
time-pressure. Thanx for your constructive answer!

Hello,

I've done this (for the windows platform only), but with tomcat 4.0.1
I'd changed the code so that the "work" folder used by Tomcat would now be
housed ni the Windows TEMP folder.

I think Tomcat 4.1.24 has a way to specify the location of the CATALINA_TEMP
folder.

You'll have to use this folder (or folders) to be used as the logs and the work
folders.

I've used NSIS to configure some other things before starting Tomcat via my own
executable Jar. I have a Swing UI which makes use to tomcat components.

Some questions:

1. If your project is browser based, how "automatic" do you plan to make the
solution ? Will the user have to type in the URL ? (I don't know if Un*x has
anything like Windows' Internet Shortcuts).

If you could depend on your user to run some file, you might have to just alter
startup.bat, I think. You could then bundle JRE+tools.jar on the CD itself 

(I'm busy with industrial automation at factories now-a-days, and have no
access to a real Tomcat system or code, sorry...)
