Java Deployment with JNLP and WebStart Mauro Marinilli
Publisher: Sams

The good news would seem to be that of course, there a couple plugins that do neat WebStart things - including building the JNLP file from the dependencies. FAIL - java.lang.ClassNotFoundException: com.sun.javaws.servlet.JnlpDownloadServlet. But when I first started with the automated option in Netbeans to launch the project with Java Web Start. The JNLP file is generated on-the-fly and downloaded to the client-machine where it uses a Cookie and the Session ID of the already-running session to re-connect to the already-running JBoss deployment. Quite simply, Java Web Start is a mechanism for program delivery through a standard Web server. The last couple of days I went through a little nightmare: I needed to debug a Java application which showed some weird behaviour only when loaded via WebStart, but not when executed within Eclipse. The “all-permissions” tag allow to access local resources (files, network etc.). Multiple internet resources told me to . Using the JNLP file format as the applet descriptor allows applets to instantly reuse JNLP extensions previously written for Java Web Start applications, and significantly expands the capabilities of applets in many other ways. My JNLP (called test.jnlp) file looks like this. Follow all the instructions about deploying, etc. The first one from CodeCrate Cool - cooking with gas now. There are many tutorials out there that show how to deploy a simple application with Java Web Start. Note that all the jar in the lib folder need to be listed to avoid any security issues. Choose Java Web Start > Enable Java Web Start. You can permit all or deny all by using a jnlp -file. However, WebStart-based applications cannot permit preferences only. Jar -tvf WEB-INF/lib/jnlp-servlet.jar. This new design has several implications regarding Java applet usage IMO, the bugs for webstart from many years ago are not addressed, and the end users will be afraid to deploy. So, how to store user preferences for unsigned applications deployed through Java WebStart? Not only Deploying the application. What is the end user deployment for this runtime?
