Prism in Offline Mode

[Daniel]

Hi.

Does anyone know how to get Prism to work when the machine is offline?
I use Prism for a webapp running in a local Tomcat. When my machine is
offline (all network devices disabled), Prism tells me to uncheck the
"Work Offline" box in the file menu, which of course is not there.
I tried adding user_pref("toolkit.networkmanager.disable", true); and
user_pref("browser.offline", false); to my webapp's prefs.js, but to
no avail.

Thanks in advance for any help,
Daniel

Hi.

I have the same problem using Prism for a webapp running in a local
Jetty. The application should be able to run offline.
There is different behaviour while starting/running the application
being offline:
- on some machines the application does'n start at all because the
connection to localhost:8080 doesn't work.
- on other machines the application works normaly, as expected.
If I start the application being online and going offline while
working with the application the program doesn't work correctly.

Thanks for help
Harri

Is your Jetty already (and still) running when you start Prism? We had a
similar problem because our Tomcat shut down too early when Prism took
too long for copying the webapp to th user directory.

For the offline problems, I added the following code to the webapp.js:

// set online on startup
var ioService =
Cc["@mozilla.org/network/io-service;1"].getService(Ci.nsIIOService);
ioService.offline = false;

function myObserver(){
this.register();
}
myObserver.prototype = {
observe: function(subject, topic, data) {
if (topic == "offline-requested") {
if (subject instanceof Components.interfaces.nsISupportsPRBool){
// try to veto going offline
subject.data = false;
}
}
if (topic == "network:offline-status-changed") {
if (data == "offline"){
// go back online
var ioService =
Cc["@mozilla.org/network/io-service;1"].getService(Ci.nsIIOService);
ioService.offline = false;
}
}
},
register: function() {
var obsService =
Cc["@mozilla.org/observer-service;1"].getService(Ci.nsIObserverService);
obsService.addObserver(this, "offline-requested", false);
obsService.addObserver(this, "network:offline-status-changed", false);
},
unregister: function() {
var obsService =
Cc["@mozilla.org/observer-service;1"].getService(Ci.nsIObserverService);
obsService.removeObserver(this, "offline-requested");
obsService.removeObserver(this, "network:offline-status-changed",
false);
}
}

var observer = new myObserver();

Ah very nice. I used an XPCOM for one client to accomplish the same
thing, but you're right... you can do it straight in webapp.js.

Hi

Could you please explain more on how to solve the offline problem?
I can't find webapp.js on my machine.

I'm using Apache to host my web application and my OS is Windows XP.

Thanks in advance,
Charles

The webapp.js is part of the webapp bundle as described here:

Hi,

I put your scripts under the folder in which webapp.ini resides and it
works!

Thanks!
