Howdy --
I'm fairly new to Java, so I'm easily stumped. The question is: How do
I access a file within a JAR archive from a Java program?
I have a simple test program, shown below, which illustrates the problem:
import java.io.*;
import java.util.*;
public class FileTest {
public static void main (String args[]) {
File file = new File("test.gif");
System.out.println("exists = " + file.exists());
System.out.println("length = " + file.length());
}
}
If I store the test.gif file outside the JAR archive, in the same
directory as the JAR archive, everything runs fine -- the file exists
and I get the proper length. If I store the test.gif file in the JAR
archive, it can't be found and length()==0. None of the Java texts I
have on hand seem to address this issue.
TIA...
