| #### Launching WebStart from Firefox These instructions configure Firefox to launch Web Start. System Prerequisite: The Java Development Kit (JDK) or Java Runtime Environment (JRE) must be installed. update: This lab assumes access to our NMS server via http://nextmidas.com, which is not currently available. Open Firefox and go to a page with a link to a WebStart application (e.g., http://nextmidas.com/). Click on the WebStart application link. A pop-up window says you are about to open a "Java Web Start" file and asks what you wish to do. Select "Open with" and "Browse...." In the "Choose Helper Application" window, select the `javaws` application (located in the `$JAVAHOME/bin/javaws` directory), and click "Open." NOTE: With Oracle Java 8, `javaws` is found ... IcedTea-Web also has open source version of `javaws` for Java 8 and 11. Choose "Do this automatically..." and click "Ok." If it's necessary to modify how Firefox launches WebStart applications, go to Edit/Preferences and click Applications. Under Content Type, highlight Java Network Launch Protocol (JNLP) and select desired `javaws`. Note: Especially if selecting an older JDK's `javaws`, make sure only the desired JDK is enabled in the Java Control Panel. Note: The Java Control Panel was removed in Oracle Java 11 and is not provided in OpenJDK.
