Installing Java to work with IP-KVM (jnlp files)

Java Web Start has been removed starting with Java 11. To work with INTROSERV systems using JNLP technology, special configurations are required.

OpenWebStart with Amazon Corretto 8 Install OpenWebStart, then Amazon Corretto 8. This combination ensures full compatibility with JNLP files.

HTML5 Console Contact INTROSERV support to inquire about the possibility of accessing via an HTML5 interface as an alternative to JNLP connection.

Standard Connection Method

Components

  • Amazon Corretto 8
  • Firefox 56 Portable
  • Security parameter configuration

Installation Procedure:

  1. Install Amazon Corretto 8
  2. Download Firefox 56 Portable (compatible version with Java support)
  3. In the Java Control Panel, set the security level to Medium
  4. Add the KVM server address to the exception list
  5. Enable the Java plugin in Firefox

Connection Procedure:

Open the KVM address in Firefox 56, perform authentication, select the required port, download the JNLP file, and run it.

Common Issues

"Application blocked" - Check the exception settings in the Java Control Panel. TLS errors - Disable certificate verification in Java settings. JNLP fails to launch - Ensure proper file association with Java.

Security Requirements

When working with Java applications, it is important to follow security precautions. Use this solution in an isolated environment with an active VPN connection to ensure connection security.

Alternative Technologies

Modern KVM solutions with HTML5 interface:

  • Raritan Dominion KX III
  • PiKVM
  • TinyPilot
  • Dell iDRAC

These solutions provide access through standard web browsers without additional components.

The evolution of server management technologies is moving toward web standards, simplifying administration and improving compatibility.
