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


i should call javascript function java.

i use 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 java.io.filenotfoundexception.

my project uses tomcat directory structure:

-java src -webcontent  index.jsp  ->js-> myjsfile.js  ->jsp  ->web-inf  ->meta-inf

how access js/myjsfile.js java file?

edit resolved 

 string path = request.getservletcontext().getrealpath("/js/myjsfile.js");

you use absolute path read js file , absolute path of "catalina.home" can system property.
