[DRMAA-WG] Java Language Bindings 1.0 Candidate 2

[Daniel Templeton]

Peter,

You are not wrong about the DRMAA_ERRNO_NO_MORE_ELEMENTS being only for 
non-object-oriented language-without-native-lists bindings.  The IDL 
spec should, however, include enough detail to make it possible to 
generate the various other language bindings, including the non-OO 
bindings.  (The reference to the error in the Java spec it to say that 
is has no mapping.)

OK.  Now I'm confused.  I just looked through the latest IDL spec, and I 
no longer see the references to what to do when your language doesn't 
have exceptions or what to do when your language is not introspective.  
Has the IDL spec become the OO, introspective IDL spec, i.e the C#/Java 
spec?
