Running javafx from java without jfx sdk installed

Question

I need to run jfx application on client's computer(without jfx sdk installation and outside the browser) from a java code.
I also need to path parameters from java to javafx and to get return value.
What i did:
1) put a.html, a_browser.jnlp and a.jar files on the server.
2 )run javafx application from java by swt.browser.setUrl(server address/a.html)
To pass parameter:
I know single option to pass parameter - create a1.html, a2.html ... an.html for each possible parameter value and javafx will read this parameter by FX.getArgument("parameter"). This solution is ok in my case. But i don't know how to return value back to java.
thank you

Answer 1

Problem solved. I used
Context context = FXLocal.getContext();
FXClassType instance = context.findClass("loginscrean.PlayerAdapter");
ObjectValue obj = (ObjectValue)instance.newInstance();
PlayersObserver po = (PlayersObserver)obj.asObject();
po.RestartPlayersList();
in java method which was trying to connect and in RestartPlayersList(); I used FX.deferAction(function() {  method content  });
I dont't know whether it is a right way of doing it but seems to be working.
P.S. The reason why application hanged was being careless with synchronization which as a result caused a dead lock.
