ok, thanks for that, I may move to Eclipse if needed. Actually we are hacking the ClassLoader in a way we break Java Spec, so this may not be really interested for main maintainers. The idea is to split the glibj.zip: the very useful class to boot the VM (jamvm) and our custom ClassLoader are kept in a local file while all other are stored in a distant file that is accessed by our ClassLoader. The goal is to have a minimal Java environment to embed on minimal systems and that is still able to run Java apps. This hack was quite easy and seems to work, although we have to check for perfs. Now we are investigating the charsets classes since for sure we don't need them all on our minimal system. JamVM tries to load a bunch of them when initializing and we would stick to one (8859 or UTF8 for example). You may give us a hint again about how to make jamvm/gnu classpath work with only one charset. In a general way, we want to get rid off everything that would be platform specific and keep only what we need. Thanks for any info. 2007/4/23, Mark Wielaard <mark@xxxxxxxxx>:

That page is here btw: http://developer.classpath.org/mediation/ClasspathHackingWithEclipse It is slightly easier than described there now that the CDT is usually available in most distros out of the box. It sounds like an interesting hack to the ClassLoader. Please do let us know how it works out. Cheers, Mark
