How to use the .txt, .xml and .properties file inside the executable jar?

I have a java project which will read a txt file and process that.

For production purpose, I will need to generate an executable jar which contains this txt file.

I use the code like:

BufferedReader br = new BufferedReader(new FileReader("src/txt_src/sample.txt"));

My jar contains txt_src/sample.txt, but can't use it. Instead, if I put a src directory which has src/txt_src/sample.txt structure, the jar works.

It will be better to generate directly by Eclipse.

Thanks in advance!

Put your files in the assets Folder of your Project and use them with:

InputStream stream = null; 
try { 
  stream = getAssets().open("sample.txt"); 
} 
catch (IOException e) { 
   e.printStackTrace(); 
}

Treat the file as a resource and give the path as the package hierarchy.

http://docs.oracle.com/javase/7/docs/api/java/lang/Class.html#getResourceAsStream%28java.lang.String%29

You can then take the InputStream and wrap it in an InputStreamReader that is wrapped in a BufferedReader. Wrap it in a BufferedInputStream if you need to define the encoding, which you should do.

new BufferedReader(new InputStreamReader(new BufferedInputStream(this.getResourceAsStream("myPackage/myFile.txt")), "UTF-8"));
