i use eclipse and my structure looks like this:

TSG-jar
 ->src
   ->myBean.java  (here i need a path)

and another one web application

TSG-war
  ->WebContent
     ->js
       ->boot.js

so they are both in the same workspace

I call the boot.js file from TSG-war in my TSG-jar (from myBean.java), and i need a path...but i have no idea how to do it...

In myBean.java i got this code:

private String getSrc(String path) {
    try {
        BufferedReader in = new BufferedReader(new FileReader(path));
        StringBuilder sb = new StringBuilder();
        String line = "";
        while ((line = in.readLine()) != null) {
            sb.append(line);
        }
        in.close();
        return sb.toString();

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

I need the path of the javaScript.js file to send it to the function...

can u help me?

i tried:

String s = "..\\..\\..\\TSG-war\\WebContent\\js\\boot.js"
String s = "\\..\\..\\..\\TSG-war\\WebContent\\js\\boot.js"
String s = "\\..\\..\\..\\..\\TSG-war\\WebContent\\js\\boot.js"


System.out.println(getSrc(s));

its always null...

where is the error?

TSG-war is a web app, but what is TSG-jar? – Maurice Perry Dec 02 '16 at 12:26
its not the same, my file is not in the same package as the bean...not even in the same folder... – begi Dec 02 '16 at 12:27
not even in the same project... – Maurice Perry Dec 02 '16 at 12:29
simple java application project – begi Dec 02 '16 at 12:29
do u got any ideas? – begi Dec 02 '16 at 12:30
you have to provide full path if its not a web application – koutuk Dec 02 '16 at 12:30
How are the two project related (at run time?) – Maurice Perry Dec 02 '16 at 12:30
they r both in an EAR file... – begi Dec 02 '16 at 12:32
yes, at runtime – begi Dec 02 '16 at 12:32
You cannot assume that a file in a .war file is accessible from an EJB – Maurice Perry Dec 02 '16 at 12:38
so, it;s not possible? – begi Dec 02 '16 at 12:40
Not directly. But I imagine that you're calling EJB methods from your webapp, so you can read the content of the file in a string and pass it to your EJB via a method. – Maurice Perry Dec 02 '16 at 12:43
i guess, i could give it a try...thx – begi Dec 02 '16 at 12:48
