Re: [pde-build-dev] JNLP and unpacked plugins

[Thomas Hallgren <thomas@xxxxxxx>]

Hi Pascal,
what we have in mind is to materialize by clicking on a link :-) I.e. 
download Buckminster and feed it a "bill of materials". It's part of the 
"Virtual Distro" thing that we presented at EclipseCon.

I agree with your assessment. After looking at the WebStartMain source I 
see no way to pursue this approach without actually rewriting it. We'll 
have to think of something different like installing a product (using 
proper Eclipse layout) that contains only the bundles needed to run the 
Eclipse update manager and then hand control over to that. Done right, 
it should be just as efficient and a lot more flexible.

Regards,
Thomas Hallgren
