[FIXED] File doesn't read after creating jar using netbeans

Issue

i have a small application which checks for values from a file and display the result in a jframe.

A file contain list of word to check. this file is placed in project folder "testing" and the main source testing.java file is present in location "testing\src\testing"

input file : c:\document..\netbeans\testing\
java file : c:\document..\netbeans\testing\src\testing\


when i place the input file inside folder "c:\document..\netbeans\testing\src\testing\
" the input file is not taken as input, it works only when kept on folder "c:\document..\netbeans\testing\"

so when a jar file is created it has not included the input file in that, even i manually input that is not taking the input file in and working.

some path setting issue? what can be done to solve this issue?

any help pls??

Solution

Once you create the jar, the file becomes an embedded resource. If you try to read it as a File it will no long be the same file system path as you originally use in the program. It must now be read from the class path.

To read the file from the class path, you will want to use getClass().getResourceAsStream(), which return an InputStream. If your file is in the same location (package) as your class file, then you should use

InputStream is = getClass().getResourceAsStream("input.txt");

Then you can read from the InputStream

BufferedReader reader = new BufferedReader (new InputStreamReader(is));
