Spherical Easel A spherical drawing program

To view Spherical Easel as an applet, you must have the Java Plug-in installed. Installation is generally a simple step on most operating systems. Please see the notes at the bottom of this page for installation instructions and information.

1. You will first need to download and install the Java Plug-In. This usually means installing a Java Runtime Environment (JRE) appropriate for your operating system. Microsoft Windows users should note that installation generally registers the Plug-In with Internet Explorer.

2. Make sure that your browser has Java enabled. If you are using

   • Internet Explorer:select the appropriate box under the Advanced tab of the Internet Options menu item.

   • Mozilla or Netscape: select the Enable Java box in the Advanced category of the Preferences menu item.

3. Finally, if you are running Mozilla or Netscape on a Linux platform, you will need to follow these additional steps. Begin by locating the Java Plug-In under the Java Runtime Environment (JRE) directory tree. For example, it could be in

   /usr/java/j2sdk1.4.2_02/jre/plugin/i386/ns610/libjavaplugin_oji.so

   Now follow the following steps:

   • Mozilla: First, close any open Mozilla sessions. Then perform

         cd ~/.mozilla
         mkdir plugins
         cd plugins
         ln -s /usr/java/j2sdk1.4.1_02/jre/plugin/i386/ns610/libjavaplugin_oji.so
     

     You should now see the plug-in registered if you look at About Plug-ins under the Help Menu.

   • Netscape: First, set the environment variable:

         export NPX_PLUGIN_PATH=/usr/java/j2sdk1.4.1_02/jre/plugin/i386/ns610/libjavaplugin_oji.so
     

     Now start a Netscape session, close it and restart Netscape again.
