How to read a file from WEB-INF/resources folder?

Question

I am using Icefaces for webapplication development. I wish to read a file from the resources folder and use it in the sessionbean.

Actually I wish to setup Jasper Reports. I have already setup the libraries in the classpath. The problem I get is while fetching the file from /WEB-INF/resources/ folder. Everytime I run the code from SessionBean, I get the exception:

net.sf.jasperreports.engine.JRException: java.io.FileNotFoundException: /resources/reports/myreport.jrxml (No such file or directory)

The Code I use is:

public void generateReport() {
    try {
            JasperCompileManager.compileReportToFile(
                    "/resources/reports/myreport.jrxml",
                    "/resources/reports/myreport.jasper");
        } catch (Exception e) {
            e.printStackTrace();
        }
}

The above code is in the SessionBean. Plz help

You are passing relative URLs to method JasperCompileManager.compileReportToFile. This method expects filenames as parameters, not URLs.

The solution suggested in other internet forums is:

JasperCompileManager.compileReportToFile(
  getServletContext().getRealPath(xmlFile), 
  getServletContext().getRealPath(compiledFile));
