Yes, it turns out that there were significant changes between RMI alpha1
and RMI alpha2.  I converted Sirrot's rmicdf package to work under RMI
alpha2, but in doing so made the performance abysmal.  I haven't had a
chance to go back and investigate the problem that's causing the
bottleneck yet.

If you are just using the "netcdf" package but not the "rmicdf"
client/server, I think that is independent of RMI, and the expiration of
the RMI alpha should not be a problem as long as you make sure you're
not inadvertently including part of the rmicdf package that you're not
really using.

I won't be able to look at this in any more detail this week, but I've
appended a note from JavaSoft including an RMI road map.

Recently, there have been a number of inquiries about the expiration of the
Alpha2 release of RMI on September 30. Here is the roadmap for RMI. Be
assured that you will never be left without a working version of RMI. We
appreciate all the feedback that you have given us. Your questions and
comments have been invaluable in making RMI more robust. Thank you for helping
us during this alpha period.  Details of updated specifications are forthcoming.
We will keep you posted.

The purpose of this series of releases is to provide a bridge for RMI base
programs during the transition from JDK1.0.2 and JDK1.1. There are changes in
the interfaces used for object serialization and RMI that will be introduced
as part of 1.1. Our goal is to give our users sufficient time to smoothly move
forward.


* RMI Alpha2 update release on JDK1.0.2

  Features:
    - extends the lifetime of the release to January 1, 1997
    - minor bug fixes
    - Complete API compatibility with RMI Alpha2
  Available now at http://chatsubo.javasoft.com/current/

* RMI Prebeta release on JDK1.0.2

  Features:
    - RMI API update (same as JDK1.1 RMI API)
    - Object Serialization support for versioning (also in JDK1.1)
    - Programs written to this API will work with both JDK1.0.2 and JDK1.1
  Available: early October

* Netscape3.0 plug-in for RMI Prebeta

  Features:
    - Object Serialization built on Netscape JRI
    - This release will allow RMI applications to work within Netscape under
      JDK1.0.2 until Netscape releases a version that is based on JDK 1.1
  Available: early November

*RMI Beta

  Features:
    - Enhancements allowing RMI calls through a firewall
    - Performance enhancements and bug fixes
  Available: As part of JDK1.1 Beta

*RMI FCS

  Features:
    -First fully supported version of RMI for Java
  Available: As part of JDK1.1 FCS

RMI will be available as part of JDK1.1. The Alpha2 update and Prebeta
releases, independent of the JDK1.1 release, will allow users of RMI the
maximum flexibility in transitioning from the current environment to
the 1.1 environment.
