Hi all,
I am almost ready to submit my assignment.

I have one question though, I have run my assignment on the folowing version

java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)

Is this ok, for me to submit using 1.4.1 or should I test it on 1.4.2 also.

There is a line in my instructions saying that ..

"You may develop your code using any implementation of the Java 2 platform, but the submission that you return must have been tested and shown to work under a production (not development) version of the Sun Microsystems' Java 2 platform and that platform must not have been superseded by a new production version for more than 18 months by the time you make your submission."

Accoring to this does it mean that 1.4.1 has become unusable and we should use 1.4.2 . I dont know when 1.4.2 was released, has it been more than 18 months.

Has anyone submitted using 1.4.1. Also I can not make sure if the version I have is production version or a development version, how do I find out ?

Thanks,
Chirag

I coded on Java 1.4.1, but I didn't know how old it was so I downloaded the latest 1.4.2 (which was _05, I think) before submission. There weren't any problems with my code with the newer JVM, so I just said that I used 1.4.2 for development.

I assumed that any Java 1.4.x that you could download from java.sun.com was production, things like Java 1.5 beta was development and shouldn't be used

Hi Chirag,

JDK 1.4.1 was released in September 2002 and the update 1.4.2 in June 2003 I think. Somebody please correct me if I am wrong, but I don't think that sun are refering to minor updates in their rule, so JDK 1.4 (all versions) will be valid for 18 months after the next JDK is released (version 5 - this is a break from the 1.x progression of JDKs).

Regards,

Jon

Thanks for your reply guys,
I think you guys are right, 1.4.1 should be fine.
I agree that SUn may not be referring to the minor versions.

It is difficult for me to download and install the 1.4.2 JDK to test the assignment.
I will go ahead and submit the assignment with 1.4.1_01

Thanks
Chirag
