Hi All,

I am try to check whether a image is there with in the war file or not. If found I will display the image at front end. If not I want to show a custom message.

Right not I am checking like
try {
session.getServletContext().getResourceAsStream("images/client1.gif").read();
return "images/client1.gif";
}catch (Exception e){
e.printStackTrace();
return "Not Found";
}
In the above code if it throws an exception then I get the "Not Found" message.

Is there a better way to achieve this.

Thanks!

You could get the RealPath of the image using the getRealPath method in ServletContext class. That path can be used to construct a java.io.File object and you can call the exists() method on that File object, to see if the image exists. There may be better and simpler ways of doing this.
 
I agree. Here's the link: http://aspose.com/file-tools
