DST - Java RTE 1.4.2.02.01

[AndyMueller]

Guru's

I have a K420 (yeah I know ...) running 11.11 which also has not been patched in ages. The server is running Java RTE 1.4.2.02.01, which I guess has no support for the upcoming DST change. I'm unsure of which Java version I need to go to, which has the DST support, but will run on a K420. Does anyone have the answer to this? I find the http://www.hp.com/go/java site not all that useful.

Thanks in advance, Andy

Hi Andy:

Perhaps this helps:

You should not need to upgrade the Java.

Download the tzupdater utility from the above site and run it to update your Java's DST table.

This information:

For Java:

* JDK 5.0.3 or later, SDK 1.4.2.11 or later, and SDK 1.3.1.18 support the US Daylight Saving Time (DST) change
* JDK 5.0.5 or later, SDK 1.4.2.12 or later, and SDK 1.3.1.19 or later support the Canada DST changes

Is from this page:
http://www.hp.com/products1/unix/java/DST-US.html
(which is accessable from hp.com/go/java).

In a nutshell, you need Java 1.4.2.11 or late.

Also from the same site:

In addition, a new time zone update tool (TZupdater) has been released, giving customers the most flexibility in updating any 1.4.2 and 5.0 JVM with current time zone information. TZupdater is available below.

Ok, now I'm getting more confused ....
On one hand only 1.4.2.11 (or later) supports DST, but others are indicating that one can just run the tzupdater tool (which I tried to run, but errors out in a CoreDump).

The easiest thing to do, if possible is to just complete update your version of Java. I have done that on almost all the machines I have.

However, if your application locked in to a specific version of Java and you can't update, then the tzupdater is the way to go. If it works, that is.

Andy,

Not sure why you got the core dump.

I successfully ran the tzupdater against 1.4.2.04

I forgot to mention - It is my understanding that 1.4.2.11 has the updated table in it - which is why no action is becessary.
