Returning a value from a java web start application

Wondering if anyone knows if there is a way to "return" something from a java web start application into the code on the website. For example say the user needed to select a location in the java application. This would then pass the location value back to the cod开发者_运维技巧e on the webpage (which is php and javascript). I have figured out how to pass arguments into a program, but so far cannot figure out any way to get them out after much googling. Any help would be much appreciated, thanks.

In principle no, since the Webstart application can be running without any Website open at all.

But if your clients use the Java-plugin from 1.6.0_10 or later (and not Safari and some other browsers with special Java-handling), you can use a JNLP-enabled applet, which is able to do the same things as a Webstart application (i.e. loading files and such), and is always bound to a webpage. It then can use the Javascript-bridge, or simply a loadDocument with the right parameters to feed back information.

You can use URL or sockets to connect back to the "same-origin" host. You can also use BasicService to open a web page, possibly from a different server, in a browser (although this shouldn't be used to send information back, as it'll be a GET not a POST).
