Re: [Rails-devel] Java webstart (was: Rails 1.5.1 available)

[Stefan F. <ste...@we...>]

Brett:
I had a first look into adding Java Webstart support for Rails and as 
suspected there is an issue with the Classloader. Even if we provide a user 
defined classloader it is not used in those cases where Rails uses the 
Class.forName method to create new (18xx-game specific classes). This has to 
replaced.

Reference:
http://download.oracle.com/javase/1,5.0/docs/guide/javaws/developersguide/faq.html#211

In addition we have to make sure that all other resource files also get loaded 
by the classloader from the jar.

Except from that it is mainly an issue to write the ant-tasks for packaging a 
jar for Rails only and then upload this and the library jars (after signing 
them) to sourceforge. This can heavily automated by creating an ant task.

As it still requires some code/build modifications I prefer to add that to the 
to-do list for Rails 2.0 and have no intention to backport this to Rails 1.x.
