Accessing Java Applets On Series 3 JNIORs

The series 3 JNIORs used the Java Applet as a GUI. Years ago the browsers stopped supporting Java Applets due to security concerns. You can no longer open the series 3 Java Applet GUI in most browsers. You can still access it by launching it locally since it is installed as part of the JNIOR Support Tool. The security concerns over Java applets are not present when launching the Java Application locally. Here is how to access the Java Applet for a JNIOR.

NOTE: The Java Applet GUI should only be used with series 3 JNIORs. The Java Applet GUI requires that your computer has Java installed. You can check if your computer has Java by opening your command line and entering java -version. Here is a link to different JDK options.

First, make sure you have the JNIOR support tool downloaded. Here is a link for it.

Once you have downloaded the Support Tool, you’ll want to open it and find the JNIOR you wish to access the Java Applet for in the Beacon tab. Then by right-clicking it, you’ll then go to Tools/Classic Monitor, Configuration, Control Application option and select it.

After selecting this, the Java Applet for your JNIOR should open.
