Re: Java 1.4?

Hi,

I was thinking about this very issue this morning in the way into work. I did a little
bit of investigating using Oracle JDeveloper (9.0.3 preview) and found that I could
happily compile against JDK 1.4.1 with the following settings:

* Project Settings -> Libraries -> Define
o Then create a entry based on rt.jar from a JRE 1.4 copied from my windows
machine
* Project Settings -> Compiler
o Tick "Enable JDK 1.4 Assertions"
o Set the compiler target as JDK 1.4

This seemed to work okay, and compile the small example. This procedure should work
with any equivalent IDE that have its own compiler rather than using javac. JBuilder
for sure but I cannot say for ProjectBuilder as I do not know this tool very well.

Now in order to actually run your JDK 1.4 app you will need either a app server you
can remote deploy to on another machine. You could use Virtual PC and a copy of Linux
to get the same effect withouth having to shell out for more hardware.

Note that I I did not have time to try the second step, as I do not have the knowledge
set it up quickly. Most of the big IDE tools seem to support remote deployment, and
debugging & profiling in some cases, to at least some types app servers. Somebody
working on J2EE as with the original poster shouldn't notice that much different from
how they work at the moment.

This is all a bit of a klude but it would allow the original poster to continue
working with his mac box, anybody work out the correct procedures for other tools? You
could of course use this process for Swing apps: although the deploy->run cycle will
be a little less automated unless you are using webstart.

Hope this helps,

G.
