the other issue was wanting to enable cases where unpack200 was not in the JRE but yet could be supplied separately.

Re: [equinox-dev] [prov] Download manager support for pack200
I was thinking a new separate classloader containing just the Pack200 classes. We would still want to delegate to the bootclassloader for everything else. However, I doubt the Pack200 classes are by themselves in their own jar that we could just create a URLClassloader for. This was really just an idea and I haven't really thought very hard about the details :) -Andrew Thomas Watson [EMAIL PROTECTED] Sent by: [EMAIL PROTECTED] 01/25/2008 11:54 AM Please respond to Equinox development mailing list equinox-dev@eclipse.org To Equinox development mailing list equinox-dev@eclipse.org cc Subject Re: [equinox-dev] [prov] Download manager support for pack200 If the Pack200 class is loaded from the VM then it will fall under the boot class loader.

Re: [equinox-dev] [prov] Download manager support for pack200
The only support I know is in MirrorRequest#perform, but it is quite rudimentary. Essentially if the repository is local, it prefers a descriptor in canonical form (not packed/zipped), and if the repository is remote it prefers a descriptor in non-canonical form. It doesn't have any further smarts about which non-canonical form is available. Also, the pack200 processing step does a check for the unpack200 executable so it will quickly abort if unpacking is not available on the client.
