Accessing text files within a jar file

[Blake Essing]

I have a simple program that uses a text file for some static data.
When I run my program from within Eclipse or from the jar located in my
workspace it works fine because it can find the path to my development text
file. But I want to be able to run the jar from anywhere. How can I
access the file from within the jar file. Important bits of code I have
are:

private static File mFile = null;
private static String mBaseSolution = "../solution/Solutions.txt";

...

mFile = new File(mBaseSolutions);
if (mFile.exists()) {
...
} else {
System.out.println("Can't find solution file");
System.exit(1);
}

The code fails on the mFile.exists() because it can't find the correct
path.

You can get an InputStream to a file inside a jar file
in the classpath via:

getClass().getClassLoader().getRessourceAsStream()

or one of the other similar variants.
