HMC/Browser access and JAVA

My HMC access via a browser to the Integrated 3270 and Operating System messages broke again.

It is a JAVA problem. I had been running JAVA V7.21 but it won't reinstall properly again. I have JAVA 8.60 installed and it doesn't start either of the functions.

My HMC microcode is at a high level - it is supposed to support Java V8.

Any suggestions? Thanks

Both functions are working for me today. Java level:

java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) Client VM (build 25.60-b23, mixed mode)

We have had Java problems off and on but finally standardized on this version after upgrading all HMCs to the latest driver.

Thanks Skip for the reassurance that it works. I'll keep digging.

I have virtual machine with downlevel versions of browser, java and some
specific settings for HMCs, swtiches and other hardware appliances which
I cannot replace or upgrade.
It is NOT updated, I documented each setting or component version, so it
ALWAYS WORK. Despite of updates madness in Windows world.

Alan, HMC needs to be at 2.13.0 for JAVA 8 to work.

Another Data Processing mystery.

I upgraded to JAVA 8.65 and it still didn't work.

I did nothing but wait a few days and a few PC restarts later ...

I tried again today and lo and behold 3270 and operating system messages are working.

That is odd. One thing I noticed that I don't care for is that once you upgrade the HMC to 2.13.0 for the JAVA 8 support, accessing it from machines with JAVA 6 or 7 no longer works. That really surprised me, because I always thought there was downward compatibility.

You are conflating MVS with JAVA. No guarantees expressed or implied in the JAVA world.

If the SHARE Singalong were still running in high gear, we could write an anti-romantic ballad about the despair of 'Java compatibility'. I would suggest that each new Java release contains antibodies to all previous releases and--of course--to all future releases. The love doctor will advise that you get off of Java, but unfortunately that means getting off the (modern) world altogether. Prepare to live in perpetual discontent.

I'm still running Java code I wrote under 1.2.

Java code written uplevel doesn't work backwards and never did.
