U.S. Daylight Saving Time Changes in 2007

[Serguei.Goumeniouk]

Dear Experts,
To fix the problem with the U.S. Daylight Saving Time Changes in 2007
is it enough to use the JRE recommended by Sun or I have to re-create
my jar files too?
Regards,
Serguei.

Assuming the code you've put into your jar files uses Java's own classes
for time zone related activities, then using a newer JRE which handles
the new rules is sufficient.

My only addition to Steve W. Jackson's response is this:

If replacing an entire JRE is difficult or impossible in your
environment, you can use the tzupdater tool to update your JRE
in-place...you don't have to download an entire JRE to update the time
zone data. Of course, by downloading the new JRE, you get other fixes
too though.
