Not surprisingly, Sun Microsystems thinks that Linux on IBM mainframes is a Bad Idea [tm], largely I suspect because it cuts into their hardware sales. As a result, you won't be finding a Sun Java for Linux on System z. (It will be interesting if they decide to provide one for OpenSolaris on System z at some point.) > Looks like I can download Java from IBM: > http://www-128.ibm.com/developerworks/java/jdk/linux/download.html I wouldn't think you should have to. Red Hat ships the IBM Java for their other platforms. For RHEL v5 it's in the "Supplementary" channel. I would imagine you'll find it there for s390x as well. You probably don't want to get into the business of providing your own Java support. That's theoretically why you're paying Red Hat (or IBM) a good sum of money. Downloading stuff and installing it will mean they won't support any problems with that package. > but will this be good enough for our picky developers? Only they can answer that question. As James pointed out, it passes all of the tests required to be branded Java. I have seen at least one problem where the developers were claiming that IBM's JDK behaved somewhat differently than Sun's did. I don't know if it's been resolved yet or not. But, that's the first I've heard of anything like that since early 2000, when I started caring about such things. I expect your developers will whine loudly, but still be able to do their jobs.
