The current status is the draft on hessian.caucho.com. Since the IETF style didn't have a change section, we didn't really have anywhere to put the updates. > What changes should non-Java Hessian library implementors one be aware > of? For the serialization, it's mostly encoding tweaks at this point, moving bytecodes around. Although, it looks like we need to add codes for Byte, Short, and Float, since the absence is causing trouble in Java. In the normal case, those shouldn't be used. The envelope section is much less stable. We just added the streaming encoding, for example. > Is supporting Hessian 1 going to be phased out? No, it's still a subset of Hessian 2. For IETF, though, I'd thought that submitting fewer drafts would be a good idea, but it might be better to submit Hessian 1 as well, since it's easier to implement. > And please correct me if I'm wrong, but if you were using an > implementation based on the old 2.0 spec (i.e. using a protocol header > of 2.0), would this not then be incompatible with an implementation > that uses the revised spec but still publishes the 2.0 protocol > header? Yes. We've been treating 2.0 as still in the draft stage, so until it's complete and sent-off, it'll be a bit unstable. -- Scott > > Thx, > > Ben > > > _______________________________________________ > hessian-interest mailing list > [email protected] > http://maillist.caucho.com/mailman/listinfo/hessian-interest _______________________________________________ hessian-interest mailing list [email protected] http://maillist.caucho.com/mailman/listinfo/hessian-interest
