I'm new on java webstart. I'm launching it from my web browser using an embedded jnlp link in the page, it works fine. But I would like to know if there is any way to pass some information from my page to jnlp. Is that possible?
It is possible to generate the jnlp dynamically, for instance using a servlet or a jsp file. You need to set the content type so the client can understand that it's a webstart application:
response.setContentType("application/x-java-jnlp-file");
