XCore Exchange

When trying to run the xTime composer app on macOS 10.14.3 I get the following error.

Anyone have any ideas? It looks like it requires Java 5 to run, but this is ancient...

I'm also running MacOS 10.14.3 and if I remember correctly I did have to install the older version of Java.

Did you just set the JAVA_HOME environment variable to version 5 to configure it to use this version?

Thanks

I am having the same problem, where do you set the JAVA_HOME environment variable?
Thanks,
Gordon

I'm struggling to even find a place to get a copy of Java 5. Anyone know where to get this from these days?
Cheers
Joe

Java 5 for MacOS is not available. Java 5 was in the responsibility of Apple. But then, they gave up on the constant changes by Oracle and put the whole responsibility over to Oracle.
And from then on, you got that catch 22. Oracle doesn't have a version 5 for MacOS and Apple no longer supports version 5.

I can't run xTimeComposer either. Is there anyone can run it on macOS Mojave?

My environments:
macOS Mojave (Version 10.14.6),

Java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)


When I open xTimeComposer, I got this message box:
"To open xtimecomposer.app, you need to install the legacy Java SE 6 runtime."

I don't think we can download and install Java 6 nowadays.

If you have a similar environment, please share how you run xTimeComposer, thank you very much.
