I want to download a pdf file which is stored in the folder which is in WebContent of project

Question

This is my Strut file.

Answer 1

The problem with

String path2=request.getParameter("path1");

This method may return null if parameter path1 is missing. If it's not null then it should be a valid path to the readable file that you application has access.

Read the example How to read file in Java – FileInputStream. You can trace the output with the code.

System.out.println("Total file size to read (in bytes) : "
                + getFileInputStream().available()); 

The getter is needed to return a stream result, and as you are using dynamic parameter in the result config. You should provide the getter for fileName.
