jsf getResourceAsStream()

[Bill Zelan]

I am trying to read a properties file in my web application. Whenever I try to read the file I get a null pointer exception. The code that is causing the problem is pasted below.

InputStreamReader isr = null;
BufferedReader br = null;
try
{
   try
   {
      //Below line is causing the null pointer exception.  Hard coded filename just to illustrate problem
      isr = new InputStreamReader(FacesContext.getCurrentInstance().getExternalContext().getResourceAsStream("/WEB-INF/test.properties"));
      br = new BufferedReader(isr);
         if(br.ready())
          {
           //Do Stuff
          }
   }
   finally
   {
      br.close();
      isr.close();
   }
}
catch(Exception e)
{
 e.printStackTrace();
}

Hi,

You have to laod the resource bundle for the properties file first.

Try this:

ResourceBundle resourceBundle = ResourceBundle.getBundle( propertyFileName);

Now whenver you need to access a key from the properties file use:

return (String) resourceBundle.getObject(key);

No I don't think that is the problem. It seems to be an issue with the way tomcat handles files in the web app (exploded or in a war). I don't think tomcat can locate the resource. All the java files in tomcat get placed in the build directory in the corresponding package, so what relative or absolute path do I have to use to point to files in the WEB-INF directory?

Hi,
I've a question related to FacesContext.getCurrentInstance().getExternalContext().getResourceAsStream() function, it returns only the web application name as string and I wanna to get a property file read from WEB-INF folder. But throws null pointer exception when I not give path to getResourceAsStream("/WEB-INF/A.properties").

I hope the WEB-INF folder is added with the web application's class path, so it has to retrieve the file right? Kindly clarify me. Thanks in advance.
