file not found exception in jar

Question

public class ABC {
    public ABC() {
        File file = new File(\"xyz.xml\");

but when I run my jar as follows:

java -jar filena         


        

Answer 1

The NullPointerException is a clear indication that the file was not found.

InputStream input=ABC.class.getResourceAsStream("/Element.xml");

Where is your XML file? If you place it in the same package (directory inside the jar file) as ABC.class, then it should be Element.xml without the leading slash.
