RE: Java Apache to Office 365

I’m now trying to figure out how to upgrade my Java on the IBMi 7.1. I know it’s an older IBMi, but I should be able to upgrade to Java 1.8.
I’ve never done upgrades or PTFs on an IBMi, but I’m going to have to learn.

We’re currently at Java 1.6. From everything I’ve googled, the upgrade shouldn’t cause any problems with my existing applications.
According to the google “AI overview” a prerequisite is PTF Group SF99716.

However, according to this page https://www.ibm.com/support/pages/ptf-groups-and-latest-sr-fp
PTF Group SF99716 is for an IBMi 7.2. The PTF group for IBMi 7.1 on that page is SF99572

My inclination is to trust the IBM page over the AI overview, and the IBM page also lists Java 8.0 SR7 under SF99572.
However, the SF99572 PFT link on that page is broken.

I also found this link https://www.ibm.com/support/pages/support-java-development-kit-jdk-80-ibm-i-os
It has a video I’m going to watch after sending this e-mail.
It also has a link for SF99572 PTF updates, however, that link is also broken.
Does anyone know if I can get SF99572?

Thanks,
Charles

I added -Dcom.ibm.jsse2.overrideDefaultTLS=true
I’m still getting the error IBMJSSE2 will not allow protocol SSLv3 per com.ibm.jsse2.disableSSLv3 set to
TRUE or default

I also get these messages, at the bottom.
SSLv3 protocol was requested but was not enabled
Unsupported protocol : RC4
Unsupported protocol : MD5withRSA
Unsupported protocol : DH keySize < 768
SSLv3 protocol was requested but was not enabled

SSLv3 protocol was requested but was not enabled

main, setSoTimeout(60000) called

What I don’t understand is, I’m expliciately saying
System.setProperty("mail.smtps.ssl.protocols", "TLSv1.2");

Why would it be doing SSLv3 when I said TLSv1.2?

I need to backtrack a bit. I think I made a mistake in my testing yesterday.
Maybe I tested the old one twice.

Despite my change, when I retested this afternoon, I’m still getting this message.
IBMJSSE2 will not allow protocol SSLv3 per com.ibm.jsse2.disableSSLv3 set

I’m going to have to research this message further.

I have this solved, all that's left is to update all my Java programs and test them.
A quick test of one program worked.

I following your instructions to add -Djavax.net.debug=all.
The first message I got was:
IBMJSSE2 will not allow protocol SSLv3 per com.ibm.jsse2.disableSSLv3 set

A little research, I needed to change the system value QSSLPCL to *TLSV1.2.
I did that and my program works.

Thanks for the help!
