I haven't had much experience of actually using the foundation jar AFAIK it's mainly used to compile against - to check whether you're using any API calls outside of the foundation execution environment but you're free to ignore this and compile against a different JVM EE such as Java5 if that's what you want - ie. foundation is just another spec'd execution environment like Java5 SE or Java1.4 EE - Is it possible to create bundles that use Java 5+ features (like generics, > additional collections classes, etc.)? certainly, we have several Java5 bundles at OPS4J and even some that we provide for both 5 and 1.4 runtimes by using retrotranslator - How can I correctly build and run bundles using these newer features? it's mostly just a matter of configuring the maven-compile-plugin to use the right source and target (ie. 1.5) and then ensuring you use a Java5 runtime to deploy it on - you should also pick the right EE in Eclipse (not sure which panel this is on) I realize that these are fundamental questions but I appear to be missing > the fundamentals.
