Re: [platform-dev] WebStart

>>Is it possible to deploy a RCP application through Java WebStart?

I've tried but I did not make it happen.

One limitation of JWS is that everything has to be delivered in JARs and all
resources must be loaded from that JAR via
classloader.

http://java.sun.com/j2se/1.4.2/docs/guide/jws/developersguide/development.html#retrieving

I tried a "Mega"-JAR (included all plugins) but it did not work because of
classloader problems.

What does work nicely is writing SWT/JFace code (i.e. no plug-ins/RCP) and
delivering it through JWS.

Here are some templates (worked w/ 3.0 M2, i. e. before OSGi runtime):
