Access a js file from java in a project with tomcat directory structure (java.io.FileNotFoundException)

I should call a javascript function from java.

I use a ScriptManager:

ScriptEngineManager factory = new ScriptEngineManager();
ScriptEngine engine = factory.getEngineByName("JavaScript");
engine.eval(new java.io.FileReader("js/myjsfile.js"));
Invocable inv = (Invocable) engine;   
Boolean val=(Boolean)inv.invokeFunction("check", value);

I obtain a java.io.FileNotFoundException.

My project uses the tomcat directory structure:

-java src
-WebContent
 index.jsp
 ->js-> myjsfile.js
 ->jsp
 ->WEB-INF
 ->META-INF

How could I access to js/myjsfile.js from a java file?

EDIT I resolved with 

 String path = request.getServletContext().getRealPath("/js/myjsfile.js");

You could use the absolute path to read the js file and The absolute path of "catalina.home" can be get from the System property.
