All, I updated the 0.6.1 version of the Java language binding spec to bring it into sync with the IDL 0.3.5 spec (with the exception of the "reason" property of the JobInfo class, which was not introduced into the DRMAA 1.0 spec). What I want to do next is work on a 0.7 version which includes some of the lessons I've learned since we released the 0.5 implementation with SGE 6.0u2. Probably the wrong audience to ask, but are there any opinions as to whether I should update the spec for J2SE 5.0 or leave it in a J2SE 1.4 compatible state? There are several strong advantages to 5.0, including type-safe enumerations and generics. The only disadvantage is that the new 5.0 syntax is not backwards compatible, which would force all DRMAA implementations to move to J2SE 5.0. 5.0 is available on most platforms these days. MacOS X < 10.4 is one notable exception, though. Daniel
