Hi,
I'm using Processing in a stand-alone application, based on Firefox.
I'm doing all my GUI in HTML/CSS/JavaScript, and the visualization using Processing. Thus as a developer I have full control over the html/browser/java version and configuration in the client app (I took example on processing to bundle the JRE with my app
)
I'm using JNLP to embed the applet in the html page.
Actually, it works great with P2D! (no dependency issue, no error when talking with javascript, no performance issue, it runs smooth, fullscreen, reactive etc..)
But I still have problems with OpenGL, which I would like to use for performance reasons (I did various benchmarks with Netbeans IDE, which is great to develop with Processing, and primitive drawing time seems to takes a lot)
This happens when I substitute P2D with OPENGL in the screen(...) method. Quote:basic: JNLP2ClassLoader.getPermissions() X
basic: JNLP2ClassLoader.findClass: javax.media.opengl.glu.GLU: try again ..

Here is how I declare the Processing applet in my HTML code :
Quote:<applet id="myapp" name="myapp" code="Ignored" width="1024" height="768">
<param name="jnlp_href" value="myapp.jnlp">
</applet>
And here is the content of the myapp.jnlp, to cover the full dependencies:
Quote:<?xml version="1.0" encoding="utf-8"?>
<jnlp>
<information>
<title>myapp Applet</title>
<vendor></vendor>
<description kind="short">A simple applet.</description>
<offline-allowed/>
<shortcut online="false">
<desktop />
</shortcut>
<!--<icon href="loading/2.jpg"/>-->
<icon kind="splash" href="loading.gif"/>
</information>
<resources>
<j2se version="1.6+" initial-heap-size="128m" max-heap-size="512m" />
<jar href="myapp.jar" main="true" />
<extension name="opengl" href="opengl.jnlp" />
<extension name="jogl" href="jogl.jnlp" />
<extension name="core" href="core.jnlp" />
<extension name="pdf" href="pdf.jnlp" />
<extension name="itext" href="itext.jnlp" />
</resources>
<applet-desc name="myapp" main-class="myapp.Main" width="1024" height="768">
<param name="jogl.silent.noddraw.check" value="true"/>
</applet-desc>
</jnlp>
I had to put each jar in it's own jnlp to resolve some deployment bugs (mix of signed and unsigned jars).
jogl.jnlp is a little special : I downloaded all the jars and jnlp from the official sun websites, and edited this jnlp to replace absolute url's by relative one (so it use my own local files, since I'm packaging an offline application, after all), and only once it was done, the applet could be loaded, so it looks like it "should" works (but still, only in P2D mode. if I put OPENGL flag, it raise the exception).
But maybe there is something I missed?
I'm using the Java Console in full debug mode, to trace every single step of the applet initialization, jar loading and so on, but couldn't find a clue. I wonder if I should post it here too ? (it's a big log file)
