All of the JOGL and GlueGen-related + * jars must be signed by the same entity, which is typically Sun + * Microsystems, Inc. <P> + * + * To deploy an applet using both JOGL and JOAL, simply add joal.jar + * to the list of jars in the archive tag of the applet, and put + * joal.jar and the joal-natives-*.jar signed jars into the same + * codebase directory on the web server.

It is not possible + * to specify e.g. -Dsun.java2d.noddraw=true or + * -Dsun.java2d.opengl=true for better control over the Java2D + * pipeline as it is with Java Web Start. However, the + * JOGLAppletLauncher tries to force the use of + * -Dsun.java2d.noddraw=true on Windows platforms for best robustness + * by detecting if it has not been set and asking the user whether it + * can update the Java Plug-In configuration automatically. If the + * user agrees to this, a browser restart is required in order for the + * change to take effect, though it is permanent for subsequent + * browser restarts. <P> + * + * The behavior of the noddraw-related dialog box can be changed via + * two applet parameters. The <CODE>jogl.silent.noddraw.check</CODE> + * parameter, if set to <CODE>"true"</CODE>, silences the two dialog + * boxes associated with this check, forcing it to always be performed + * and deployment.properties to be silently updated if necessary + * (unless the user previously saw such a dialog box and dismissed it + * by saying "No, Don't Ask Again"). The noddraw check can be disabled + * completely by setting the <CODE>jogl.disable.noddraw.check</CODE> + * applet parameter to <CODE>"true"</CODE>. <P> + * + * The JOGL (and optionally JOAL) natives are cached in the user's + * home directory (the value of the "user.home" system property in + * Java) under the directory .jogl_ext. The Java Plug-In is + * responsible for performing all other jar caching. If the JOGL + * installation is updated on the server, the .jogl_ext cache will + * automatically be updated. <p> + * + * This technique requires that JOGL has not been installed in to the + * JRE under e.g. jre/lib/ext. If problems are seen when deploying + * this applet launcher, the first question to ask the end user is + * whether jogl.jar and any associated DLLs, .so's, etc. are installed + * directly in to the JRE. The applet launcher has been tested + * primarily under Mozilla, Firefox and Internet Explorer; there may + * be problems when running under, for example, Opera. <p> + * + * It has been discovered that the Talkback agent in Mozilla / Firefox + * has bad interactions with OpenGL applets. For highest performance, + * we recommend disabling the Talkback agent; find talkback.exe, run + * it, and follow the directions for turning it off.
