Mark and maybe Steve, I've built, incorporated and committed shareable libraries for JNIAST and JNIHDS for the AMD64 architecture, that's the 64 bit JDK1.5.0. Mark, JNIAST passes its test, but JNIHDS needed a modification for testing the size of an HDS locator (under 64 bit architectures the size of a locator is 16 characters, not 15, in fact I think you can only say that a locator is at least 15 characters, so it now just tests that). Cheers, Peter.
