I am launching application through jnlp, where i need to read the database configuration from server (Tomcat). Is it possible to connect to the host address or can i read properties file before jnlp launching the application?
Is it possible to connect to the host address..?
Yes. Even a sand-boxed JWS app. can 'phone home'.
Form an URL relative to the codebase of the application (is usually easiest). To gain the codebase, see BasicService.getCodeBase(). Here is a demo. of the BasicService (it includes source and build files).
