It is possible get a javascript value and put inside a java variable.
EX:
var len = $(" #relacaoPax select[name=tipo] ").length;
console.log( "len = " + len );
});
<% int l = len;
System.out.println( "//L = " + l );
%>

You would need to use AJAX on your page.
If you’re using JSF, take a look at the tag f:ajax.(http://uaihebert.com/jsf-exemplos-simples-com-ajax/)
JSP + Servlet: http://www.klebermota.eti.br/2013/10/23/ajax-com-jsp-e-servlet-usando-jquery/

It is not possible to do what you want because all the JAVA code of your page is processed on the server and when you get to the browser there will only be HTML and JAVASCRIPT code to be interpreted.

You need AJAX, which is already a saturated subject. Some references: http://answall.com/questions/15028/popup-com-ajax-e-jquery/15081#15081 and http://answall.com/questions/22446/chamar-m%C3%A9todo-java-no-javascript/22464#22464
