Updating Console.jnlp

Eugene_van_Heer — Wed, 18 Nov 2020 15:11:30 GMT

I need some assistance please on how to update the Console.jnlp please:

The problem:
We are running XMC 8.3.2.11 on a Windows Server 2012R2 as a Virtual Machine (Hyper-V).
I am accessing the legacy console via a Windows 10 Machine using Java 8 Update 271

When I try to launch the console from the Web link, it stops at Loading Cache (whether I disable cach in the Java app on my laptop or not).

This is the output of the Java Console:

But when I save the Console.jnlp to my laptop and then edit it and change the following line, and then launch from that saved file, then it loads fine. (Doubling memory to 2048)

How do I update the console.jnlp on the server itself so that any machine can load it directly without having to save and edit the jnlp file?

Eugene,

FYI as from XMC 8.5 there is no more java client. Only the web GUI is available.

All the options & features have been migrated in.

I’m not sure you’ll be able to adapt this but you can try to find the jnlp.

Try “find / | grep .jnlp” on XMC but perform a backup before modifying any files.

Thank you for the reply. I will try that (after the required c.y.a. backup naturally).

Sad that the legacy Java Console about to disappear when we upgrade.
I find the console does certain things a bit easier than the Web interface. (Progress I guess. “This motorized carriage will never replace horses”)
