As David pointed out, Sun doesn't provide binaries for anything to run on IBM's mainframe architecture. In the general case, though, the question of "why" boils down to what ever the ISV decides is in their best interests as a business, since it takes quite a bit of time and money to certify and support a product on any given platform. That's why you'll see some ISVs certify their product on SUSE Linux, but not Red Hat, or vice versa. It all comes down to finite resources.

They are runnning on a 64-bit SLES9 server. We have told them that it would not be a vendor certified configuration (BEA says to use IBM 1.4.2 s1ra). We also stated our IBM support contract would most likely not cover this. They want to know WHY only IBM JDK's are certified. They commonly use Java hot spot options that are not available with an IBM JDK (options that let you split into multiple heaps). In any case, are there any stats available to show that the IBM JDK is best for the platform? Or a good answer to the WHY? ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
