How to run WebStart application offline

When using Java WebStart application, people are sometimes disturbed by the fact that the application checks for a new version at every start. If they look at the WebStart documentation, they would find out, that it is very well possible to start WebStart application offline, i.e. without checking for a new version. When you start your WebStart application from the WebStart GUI, you just select Run Offline from the right-click popup menu (as it is shown on the picture). Note, that WebStart GUI can be started on Linux using following command (depending of version of your Java): javaws or javaws -viever When  you start your WebStart application from the command line, you should add -offline option, like this: javaws -offline Koala.jnlp Note also, that an application provider can specify in JNLP configuration file that his application should be started offline by default. There are several WebStart applications in Atlas, I've made a post about them earlier: Java Web Start in Atlas. This is a reaction to post EVO Sucks in another blog.
