Question

I´m doing a javaEE application and I´m using spring to inject my ejbs and WAS7, currently I´m running it in a windows environment altough in the end it will run in a unix environment. So I create a java class that acts as my controller for spring and I´m supposed to get some data from a jsp and turn it into an excel. So when I try to get an image from my web-content folder so I can put it into my excel y get file not found.
This is what I´ve tried so far without success:

    String path = File.separatorChar + "img" + File.separatorChar +  File.separatorChar + "logoCorporativo.jpg";
    System.out.println(path);

    try {
        FileInputStream fis = new FileInputStream(path);
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

and

        String path = File.separator + "img" + File.separator +  File.separator + "logoCorporativo.jpg";
        System.out.println(path);

    try {
        FileInputStream fis = new FileInputStream(path);
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

I found that when I typped “http://localhost:9080/AdminMapasWeb/img/logoCorporativo.jpg” into my browser I can see the image.

Does anyone am I getting a FileNotFound Exception???
Thanks in advance.

Use

File file = getRequest().getServletContext().getRealPath("/img/logoCorporativo.jpg");

getRealPath convert a URL root relative path (using slashes “/”) to a File.
If the war does not unpack itself on deployment, getRealPath returns null.
