So you would ned to make a call to the server.epascarello– epascarello2016-09-15 20:33:18 +00:00Commented Sep 15, 2016 at 20:33

I think more context is needed. Is this a Java function in an Applet? Are you talking about a GWT problem?GC_– GC_2016-09-15 20:34:09 +00:00Commented Sep 15, 2016 at 20:34

Like @epascarello implied an ajax call to a servlet would normally work.GC_– GC_2016-09-15 20:35:27 +00:00Commented Sep 15, 2016 at 20:35

A few thoughts... You could use ajax to call what I assume could be a jsp page. Another option, use React JS or Angular JS to connect server-side.parabolah– parabolah2016-09-16 01:49:01 +00:00Commented Sep 16, 2016 at 1:49

I'm not sure what the structure of your code looks like but you cannot call a java method directly from javascript. You would need to use something that can map your URL to the method you are calling. You would need to make a servlet or JSP and use an ajax call to communicate to the server and call your desired method.
The following tutorial should help you get started writing something like this:
