I cannot say, but just to signal that you posted an java question under a javascript forum.
My java is rusty, but if there is one thing I know for sure, it's that java and javascript have nothing in common, except a part of their name.

You cannot use java code into a javascript web page section.
You need to expose your java functions via an API to http requests. Via REST, for example.
Then you can use AJAX asynchronous requests from the web page javascript to your API.

I say REST because I don't think that javascript can do xml-rpc, soap or corba calls.
But I am not certain of that.

like tripy said, You cannot use java code into a javascript on a web page section. It just wont work out.
