Can't launch DELL iDRAC virtual console via viewer.jnlp

Issue

viewer.jnlp downloaded from DELL iDRAC 8 admin console does not launch iDRAC Java virtual console application. The PC has 64bit Java SE Development Kit v17.0.1 installed.

viewer.jnlp

When the file is opened with C:\Program Files\Java\jdk-17.0.1\bin\java.exe, the command prompt opens and then immediately closes. The actual error is:
Error: Could not find or load main class
Caused by: java.lang.ClassNotFoundException

When the file is opened with C:\Program Files\Java\jdk-17.0.1\bin\javaw.exe, nothing at all happens.

Resolution

The issue was resolved by installing 32bit version of Jave SE Runtime Environment (from: https://www.java.com/en/download/manual.jsp) and then associating the.jnlp file extension with C:\Program Files (x86)\Java\jre1.8.0_331\bin\javaws.exe.

You may also need to add the server's IP to Java Control Panel Exception Site List.
