With a previous version of Lightstreamer I was able to put a file called ErrorPage.html into the shared/classes directory and the engine would serve that if someone accessed an invalid page on our server. I see that the latest distribution still has an ErrorPage.html inside the Lightstreamer.jar which I presume generates the "Lightstreamer is up and running" page. But adding my own to shared/classes seems to have no effect in overriding it. I'd rather not have to modify the Lightstreamer.jar to insert my own page so is the shared/classes method still supported? If so any idea why it doesn't work for me?
