Class InstallerDesc

java.lang.Object
net.adoptopenjdk.icedteaweb.jnlp.element.extension.InstallerDesc
All Implemented Interfaces:
EntryPoint
public class InstallerDesc extends Object implements EntryPoint
A JNLP file is an installer extension if the installer-desc element is specified. It describes an application that is executed only once, the first time the JNLP file is used on the local system.

The installer extension is intended to install platform-specific native code that requires a more complicated setup than simply loading a native library into the JVM, such as installing a JRE or device driver. The installer executed by the JNLP Client must be a Java Technology-based application. Note that this does not limit the kind of code that can be installed or executed. For example, the installer could be a thin wrapper that executes a traditional native installer, executes a shell script, or unzips a ZIP file with native code onto the disk.
