[kepler-dev] Re: Applet for morpho

$PTII/doc/codedoc.htm sums up the code generator, though the docs are
out of date, pending updates by me.  I expect to do this the second
week of June.  There is a chapter for the manual that Steve
Neuendorffer started, and I need to update it with applet info.

Applets really work best if the classes are wrapped up in jar
files.  The applet code generator looks for the appropriate jar
files and includes them in the applet archive parameter.
(The applet code generator will optionally copy them to a new location
if the destination of the .html file is outside the Ptolemy tree)

To create the appropriate jar files, run
   cd $PTII
   make install
before running the applet code generator.

Steve polished the $PTII/bin/copernicus facilty so
that it is much easier to run the code generator.

The quick and dirty test is:

  cd $PTII/ptolemy/domains/sdf/demo/Butterfly
  mv Butterfly.htm Butterfly.htm.bak
  $PTII/bin/copernicus -codeGenerator applet -targetPath ptolemy/domains/sdf/demo/Butterfly Butterfly.xml

For help, try
  $PTII/bin/copernicus -help 

The applet code generator reads templates from 
$PTII/ptolemy/copernicus/applet:
  model.htm.in is the default template for applets that do not
        use vergil
  modelVergil.htm.in is the default template for applets that
	use vergil

These templates have complex javascript in them so they will support
Netscape 4.x.  It would probably be better to use simpler 
templates that just have the <applet> ...</applet> tag.
If a simpler template is used, it might be worth having a simple
applet on one of the first pages that a user would go through
that verifies that they have Java 1.4 running
See:
http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII4.0/JavaVersionApplet.htm

The applet code generator can also copy the jar files to a different
location:

   $PTII/bin/copernicus -codeGenerator applet -targetPath Butterfly -ptIIUserDirectory /home/eecs/cxh/public_html/tmp Butterfly.xml

The results are visible at
http://ptolemy.eecs.berkeley.edu/~cxh/tmp/Butterfly/

The applet code generator also has a start on some facilities to
generate WebStart applications, which are much more robust.  However,
this facilty is not yet complete.

BTW - Recently, Efrat had some questions about applets, my response
can be found at:

--------

    Creating portable applets is a major challenge...
    This is partly because of the Sun-Microsoft war, and partly because
    of fundamentally bad design... That said, Christopher Brooks (cc'd here)
    has done amazingly well at this... There is a "code generator" in Ptolemy
    that will produce a starting point for an applet. Perhaps Christopher
    could summarize how to use it?
