NetXMS Support Forum

Hello again

I'm currently attempting to use NXShell and am receiving the error below. I'm using nxshell-2.0-M5.jar alongside a 2.0-M5 installation. Is there a fix for this?

[dev1]$ java -Dnetxms.server=127.0.0.1 -Dnetxms.login=admin -jar nxshell-2.0-M5.jar

Thanks in advance!

Upgrade Java to version 7 at least. I, however, highly recommend to use latest Java8 because of numerous security issues in older java versions.

This fixed it. I thought we already had updated, apologies for the easy fix.
