Hi, I need to update the javax.mail package, because the code I've been
using since July 2021 has now started throw exceptions about an inability
to find a javax activation class but seemingly were to find an upgrade
isn't well documented.

I'm currently using Open JDK 1.8 under Fedora 35 but it seems that
javax.mail is apparently not available as a standard dnf package. At least
so far, I haven't been able to find a Fedora package containing it.

Its late, and I seem to be going in circles, so I thought I'd ask you guys
what I've obviously missed and crash til morning.

TIA.

The canonical download sites must be:

https://github.com/javaee/javamail

and:

https://github.com/eclipse-ee4j/mail

But I suspect most use Maven repo today.

currently using
https://mvnrepository.com/artifact/com.sun.mail/javax.mail
which now has newer versions in a different artifact
https://mvnrepository.com/artifact/com.sun.mail/jakarta.mail

It helps if you can let maven manage dependencies.

I'm unreconstructed enough to be using ant rather than maven.

But thanks to the pointers I was given on this thread I've not only
discovered that javax.mail is now jakarta.mail and that it has good
Fedora/OpenJava support, but also that using dnf to install "jakarta-
mail.noarch" pulls in both the jakarta-mail and jakarta-activation
packages, which is exactly what I need.

Hey Martin:

https://eclipse-ee4j.github.io/mail/#Download_Jakarta_Mail_Release

Not sure where to get the latest jakarta.activation.jar.

Java 8 is way beyond end of life. The current version is 18 but 17 is
the latest LTS.

Some time ago they changed who was working on JavaMail and the package
name changed to jakarta.mail and jakarta.activation. You need both jars.

You can go to my website and get both files:

Sure, but Fedora is currently supporting 8 and 11: I've just downloaded
and installed jakarta.mail 1.6 as a Fedora package. Haven't had time to
recompile the affected program yet - currently too busy with gliding club
planning stuff.

Thanks, but picked them up as RH Fedora packages already ;-)

Using Java 11 at work, as I recall the transition from Java 8 was pretty smooth; upgraded my personal repo to 17 with no issues.

Good to know. This lack of surprises is one of Java's better features. I'm
still running code that was written for Java 1.4 and that has never needed
to be modified since it was written.

Unlike some other languages it never seems to obsolete any syntax, and so
by and large, its as easy to recompile with a later compiler as C.

This is quite unlike, e.g. COBOL, though in fairness the much of the stuff
that language obsoleted deserved to die, e.g the ALTER verb, which allowed
a program to modify its own logic paths by changing the destination of a
GO TO statement.

No.

Oracle commercial Java 8 is supported until December 2030.

Eclipse OpenJDK build is supported until at least November 2026.

You are right about that Arne, you can pay for support. It's still
toast though:

https://blogs.oracle.com/java/post/end-of-public-updates-is-a-process-not-an-event

Every new beginning comes from some other beginning’s end

Java SE 8 was released on March 18th in 2014. By the time Oracle Java SE
8 reaches the end of public updates for commercial users in January
2019, Oracle will have provided almost five years of continuous, free
public updates.

With an Oracle Java SE Subscription, commercial users can continue to
benefit from support and regular updates to Oracle Java SE 8, including
enhancements and critical patches, for an even longer period of time.
For example, the Java Web Start technology will continue to be
commercially supported in Oracle Java SE 8 until at least March 2025.

Not all users of Oracle Java SE 8 use it commercially. Some use it to
play games, or to run consumer productivity applications. Oracle will
continue to provide free public updates of Oracle Java SE 8 for personal
users until at least December 2020. During that time, personal users
should contact their application providers and encourage them to migrate
their applications to the latest version of Java, or else switch to
alternative applications.

Both OpenJava 8 and 11 are also supported under Fedora Linux,

You can pay Oracle and get updates until 2030.

You can get updates for free for Eclipse OpenJDK build
until at least 2026.

It is only toast for those that don't want to pay and don't
want to use the open source version.

Yes.

The Redhat OpenJDK builds of Java 8 has the same EOL as
the Eclipse OpenJDK builds: November 2026.
