Yes. Licensing, supported platforms, and internal structure. Blackdown is basically open source, created in close relation with Sun, supports more hardware, and tends to lag. I've heard the Sun prefers to write as much of Java in Java as possible, and that IBM prefers to write it in C. I don't know if that's true. They don't say it in as many words, but one of IBM's JDKs works on standard home Linux PPC. If both are available for your platform, and it matters, you should do benchmarking and regression testing with both. If it doesn't matter as much, pick your favorite company. I personally prefer IBM. > Also, is there a difference between a "java developer's kit" and "sdk"? Generally? A JDK is and SDK, although recently Sun has started shipping an IDE with one of their releases. I find it slow and annoying--Eclipse is faster and easier to use. That might be what they're calling the SDK now, I'd avoid it. In case you don't know, the difference between a JRE and JDK is that the JDK is a superset of the JRE in that it also contains a compiler and other development tools. -- Stuart Jansen "The gods do not protect fool.
