Loading a file image in a war project

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.

@Joop `getRequest()` method is not compiled . i get compile time error saying method not found – Santhosh Sep 23 '14 at 10:18
@SanKrish he HttpServletRequest parameter if the code is in doGet/doPut/..., normally called `request` – Joop Eggen Sep 23 '14 at 10:31
@JoopEggen Actually my code is in the spring controller. so i tried `request.getServletContext().getRealPath("/img/logoCorporativo.jpg");` but still i get `NoSuchMethodError` – Santhosh Sep 23 '14 at 10:50
`request.getRealPath("...")` (from ServletRequest) should then do. Later versions provide a `getServletContext` which makes sense for a non-request function. – Joop Eggen Sep 23 '14 at 12:05

your file is packaged inside the *.war archive, so its not a standalone file on the file system (like it is in development) try using getClass().getClassLoader.getResourceAsStream() to get at it

Best solution if you can put your image in the class path as resource. – Joop Eggen Dec 26 '12 at 17:21
or simple place it inside your *.war archive, something maven will do for you if you put it in /src/main/resources – radai Dec 26 '12 at 18:53
