问题
I'm trying to migrate a Java applet to a Java web start application. The applet was activated from a JavaScript with several parameters, some are not hard-coded (sessionId, tempFilePath):
deployJava.runApplet(attributes, parameters);
In order to migrate the applet I'm using a simple JNLP file with applet-desc tag. And from the JavaScript I call:
deployJava.launchWebStartApplication('$jnlp_path');
I just can't understand how to pass to the web start application the parameters that were created by the JavaScript.
回答1:
OK, so it turns out that using deployJava.launchWebStartApplication(...) triggers security restrictions in Chrome and IE.
What I did is kind of work around: I sent an HTTP request to my server and the server's response was a JNLP content.
On the server side, I edited the JNLP on runtime and each time I inserted the required parameters.
When the browsers receive the JNLP content they trigger the download of the required jar.
And that's it!
