Java in Firefox Extensions - MDC. Note: Out-of-process Java, enabled by default on all platforms but Windows, currently breaks this code in the Firefox 4.0 betas; see bug 563891. Since bug 563891 is designated as a soft blocker, the functionality upon which the below code depends may or may not be available in the final Firefox 4.0 release. If you are in need of calling Java code from within a Firefox extension, you can make use of LiveConnect. LiveConnect gives your extension's JavaScript code (linked from or contained in XUL code) access to 2 objects: java and Packages (note that per this thread, although the new documentation for the LiveConnect reimplementation states that these globals will be deprecated (in the context of applets), "Firefox and the Java Plug-In will continue to support the global java/Packages keywords, in particular in the context of Firefox extensions. "). These 2 objects let you make use of the standard JDK classes, e.g., var aJavaList = new java.util.LinkedList();
Can a Java application communicate with a firefox extension? - m. New To Java - How to run Java from Firefox Extension using livec. Java Firefox Extension. I know, you won't find this as the first search result on Google, but anyway... Because I promised some (many) posts ago and because recently I found the time to create a decent example (actually, I HAD to find the time), here's the long waited demo of a Java Firefox extension, i. e.
Firefox extension that uses Java code. I first got this idea from Simile's Piggybank extension, and then I got their example from I found that to be quite complicated so I created a new one, simpler (and optimized in some points) and, I think, easier to understand.I assume you are familiar with the Firefox extension development. If you're not, have a look at we already have in Firefox: We will create a XPCOM component that will use LiveConnect to get to the Java code. Why can't we do it only with LiveConnect? But what's the trick to access the Java code? Happy coding! Dev : Extensions : Example Code : Calling Java from Javascript - From MozillaZine Knowledge Base This page is currently notes of what I had to do to call Java from Javascript from Thunderbird. Here's an example from a blog: var cl = new Packages.java.net.URLClassLoader( [ new Packages.java.net.URL( ' ] ); var aClass = Packages.java.lang.Class.forName("HelloWorld", true, cl); var aStaticMethod = aClass.getMethod("getGreeting", []); var greeting = aStaticMethod.invoke(null, []); alert(greeting); In order to write to the file system, I had to add this to the javascript code: java.lang.System.setSecurityManager(null); I could read a jar from the filesystem without a problem.
Calling showJavaConsole is very useful for debugging: var jvm = Components.classes["@mozilla.org/oji/jvm-mgr;1"].getService(Components.interfaces.nsIJVMManager); jvm.showJavaConsole(); Here's the code I use to log exceptions. Function logExc(e) { try { while(e ! Java Programming - Communicating with firefox. Lancer un programme externe depuis Firefox - LINUX & OPEN SOURCE. J'ai écrit une petite extension pour Firefox qui lance un programme directement depuis la barre de navigation. J'ai utilisé l'excellent "Firefox/Thunderbird Extension Wizard" de Ted Mielczarek qui créer le squelette de l'extension en moins d'une minute. C'est ici si vous voulez essayer: J'ai ensuite décompressé le fichier zip, et j'ai édité le code javascript du fichier overlay.js du répertoire content. C'est du vite fait car je ne suis pas expert en javascript. La fonction qui sera appelée lorsque l'utilisateur cliquera sur le nouveau bouton est "onToolbarButtonCommand" , il suffit donc d'ajouter le code dans cette fonction.
Voilà un rapide description: On récupère le chemin du "home directory": Puis l'adresse de la page dans la barre du navigateur: //get the url var urlstr = document.getElementById("urlbar").value On prépare les arguments qui seront passés au programme et le chemin du programme. Le code complet: var telexanlauncher = {
