The applet being deployed may be either signed or - * unsigned; if it is unsigned, it runs inside the security sandbox, - * and if it is signed, the user receives a security dialog to accept - * the certificate for the applet as well as for JOGL and JOAL. <P> - * - * The steps for deploying such applets are straightforward. First, - * the "archive" parameter to the applet tag must contain jogl.jar - * and gluegen-rt.jar, as well as any jar files associated with your - * applet (in this case, "your_applet.jar"). <P> - * - * Second, the codebase directory on the server, which contains the - * applet's jar files, must also contain jogl.jar, gluegen-rt.jar, - * and all of the jogl-natives-*.jar and gluegen-rt-natives-*.jar - * files from the standard JOGL and GlueGen runtime distributions - * (provided in jogl-[version]-webstart.zip from the <a - * href="http://jogl.dev.java.net/servlets/ProjectDocumentList">JOGL - * release builds</a> and gluegen-rt-[version]-webstart.zip from the - * <a - * href="http://gluegen.dev.java.net/servlets/ProjectDocumentList">GlueGen - * runtime release builds</a>). Note that the codebase of the applet - * is currently the location from which the JOGL native library used - * by the applet is downloaded. 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. These signed jars are - * supplied in the joal-[version]-webstart.zip archive from the <a - * href="http://joal.dev.java.net/servlets/ProjectDocumentList">JOAL - * release builds</a>. <P> - * - * Sample applet code: - * <pre> - * <applet code="com.sun.opengl.util.JOGLAppletLauncher" - * width=600 - * height=400 - * codebase="/lib" - * archive="jogl.jar,gluegen-rt.jar,your_applet.jar"> - * <param name="subapplet.classname" VALUE="untrusted.JOGLApplet"> - * <param name="subapplet.displayname" VALUE="My JOGL Applet"> - * <param name="progressbar" value="true"> - * <param name="cache_archive" VALUE="jogl.jar,gluegen-rt.jar,your_applet.jar"> - * <param name="cache_archive_ex" VALUE="jogl.jar;preload,gluegen-rt.jar;preload,your_applet.jar;preload"> - * </applet> - * </pre> - * <p> - * - * There are some limitations with this approach. 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. Please see - * <a href="http://www.javagaming.org/forums/index.php?topic=12200.30">this - * thread</a> on the javagaming.org forums and - * <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=326381">this - * thread</a> on the Mozilla bug reporting database. <p> - * - * @author Lilian Chamontin - * @author Kenneth Russell - */ -public class JOGLAppletLauncher extends Applet { - static { - try { - UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
