Re: Java JRE 6 on IBM i: How to install

Actually, Java SE 6 is available in both the classic (option 10) and 32-bit (option 11) version for V5R4. You can install JDK 6 on V5R4M0 via PTF:

Classic:

32 bit:

Here's another page on downloading the Java 6 JVMs:

Also, as a minor point, after JDK 1.4, the numbering for Java changed. The versions went from 1.4 to 5.0 (with subsequent releases being 6 - the .0 was dropped - and the soon to be released 7). Internally, the JVM still reports as 1.5 or 1.6, but you order Java version 5.0 or 6 (for example, 5722JV1 option 7 is Java Developer Kit 5.0, not 1.5).

I believe that you need to be at minimum O/S level of IBM i 6.1 to load
JRE 1.6.

When you install the O/S upgrade the JRE 1.6 will be available for you
to select in GO LICPGM option 11 (Installed licensed programs)

i5/OS V5R3 max Java level is 1.4.x
i5/OS V5R4 max Java level is 1.5.x

Hi,

I need jre 1.6 on my V5R3 box to run my application.
But only jre 1.4 is installed - when I type 'java -version' in PASE, I see java 1.4.2 .
What are the steps to upgrade to jre 1.6 ?
If I need higher OS 400 version, what is the minimal version?

Regards,

Zvi
