Java software requirements

[Tom Scavo]

On the Software Requirements page

http://groups.google.com/group/vscse-petascale-programming-2010/web/software-requirements

the PDF documentation for Eclipse says that Java 1.5 or later is
required. There is also an explicit requirement for Java 1.4 or later
under the "Client Software Requirements" section. So unless I'm
missing something, the latter is redundant and perhaps misleading. Can
someone clarify the Java requirements?

Is the JRE sufficient or is the JDK required? I suspect the JRE is
sufficient but you should be explicit so the user doesn't download and
install more than is actually needed.

Finally, Java 1.5 has reached "end of life" so users who don't have
Java installed on their system should actually install Java 1.6, I
would think.

Tom,

A JRE should suffice. They'll need a java >= 1.5 to run/install
eclipse helios (note, not galileo).

1.6.x is fine. A simple test that you've got it in your environment
looks like:

[arnoldg@rail ~]$ java -version
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8) (fedora-39.b18.fc12-x86_64)
OpenJDK 64-Bit Server VM (build 14.0-b16, mixed mode)
[arnoldg@rail ~]$

That answers my question with respect to Eclipse, thanks. What about
the following requirement on the Software Requirements page?

"The Thursday session WILL require that you have Java 1.4+ available"

What is that requirement for (or is it a holdover from a previous year)?

Thanks,
Tom
