Using the SOJA applet

SOJA stands for SMIL Output in Java Applet. It was written by HELIO in 1998.

HELIO is a French association based in Melun, France. The player is free and can be downloaded from

Helio Web Site

SOJA is an applet that render SMIL in a web page or in a separate window. It supports the following formats:

• Images: GIF, JPEG
• Audio: AU and AUZ (AU zipped) -- SUN Audio files
• Text: plain text

SOJA does not use streaming. HELIO chose to store media before rendering them. You have to wait until each of them has properly been loaded but the presentation will never be stopped.

Running SOJA

To run SMIL through an applet you have to

• call the applet from an HTML file:

  <APPLET CODE="org.helio.soja.SojaApplet.class"
          ARCHIVE="soja.jar" CODEBASE="../" 
  	WIDTH="600" HEIGHT="300">
      <PARAM NAME="source" VALUE="cardiff_eg.smil">
      <PARAM NAME="bgcolor" VALUE="#000066">
     </APPLET>
  

  .
• the SOJA (soja.jar) archive is located in the SMIL folder on the Macintoshes.
• You may need to alter the CODEBASE attribute for your own applications
• The PARAM NAME="source" VALUE="MY_SMILFILE.smil" is how the file is called.

There are plenty of HTML SMIL/applet wrapper example files in the SMIL demos folder.

RUNNING APPLETS

This should be easy to do

• Run the html file through a java enabled browser
• Use Apple Applet Runner
  • uses MAC OS Runtime Java (Java 1.2)
  • less fat for SMIL applications (we do really need Web connection for our examples)
  • Efficient JAVA and MAC OS run.
  • Located in Apple Extras:Mac OS Runtime For Java folder
  • TO RUN: Drag files on to application, OR
  • TO RUN: Open file from within application
