Java Version

[Terry Corbet <tc...@ix.netcom.com>]

There is a posting on the developers forum from last September in which folks
talked about moving to Java 5.  For reasons that may be valid within the
Jakarta development environment, the discussion was simply dropped. 
Someone, however, indicated that they were able to deploy with a Java 5
runtime.

Of course when I try to provide a CommentAuthenticator, all my development
work left 1.4 at least three years ago, and with the most recent posts
concerning forthcoming Java 7 features it is not even a question of whether
or not one should be using Java 6 today.  If there are compelling reasons
why this project cannot be developed with currently-released SDKs, can
someone please indicate if it is possible to provide plug-ins based on
anything other than the 1.4 JDK?

Acceptance of a fine body of software is being put aside because of this
dependence upon way down-level tools.

Thanks for much for the prompt, crisp, helpful information.  I should go get
the exception from the stack trace, but that would require that I restablish
the test harness, so pardon me if I try to just get it almost correct.

01.  I have the 3.1 RC running as a webapp under a Tomcat 5.5.17
on a Windows Server.  It behaves fine.
02.  I need, however, to write a CommentAuthenticator, so I follows the
great example posted.
03.  I restart, try to add a comment and -- probably for both of the
methods of that Interface, but I don't  ahve the stack trace -- I get
java class version extensions.  The class was compiled under JDK6.

If I understand what you are saying, my problem is that I compiled on
Java6, but Tomcat is running on a host with a Java5 runtime -- the
incompatibility is NOT with the 1.4 basis of the Roller app.  I will try
to create those build and test conditions and let everyone know.
If what you say is correct, I guess I have no need to worry about
moving ahead with Roller.

Thanks again, I will report results tomorrow.

Yes, I can confirm that there is no problem in working around the base system
using Java5 for my own development and test.  Thanks again.

Without trying to advocate for any stance, let me at least try to clarify 
the current state of things.

- The release is built with JDK 1.4 and source that is part of the release 
is required to be compatible with 1.4.  This only affects you if you plan to 
contribute code back to the project.

- Given this, you can run on any JDK version 1.4 or higher.  For example, I 
run my own site on JDK 1.5 and Tomcat 5.5.

- You should be able to develop your own plugins and extensions using JDK 
versions greater than 1.4 just fine as long as you then run the entire thing 
on equivalent or higher JDK versions.  This doesn't require rebuilding or 
touching Roller code.

- You should also be able to build and run Roller sources yourself using JDK 
1.5 or higher if you want if you do want to modify Roller code.

The present stance is intentionally conservative, giving the greatest 
flexibility to users, while putting additional burden on contributors to 
write source code that compiles and runs in 1.4.

For my own part, although everything else I am working on now is using Java 
1.5 or higher (so personally I'd be fine with stepping up to it)  I'm not 
sure how many sites we'd be cutting out by requiring it.

--a.
