java version "1.4.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta-b65)
Java HotSpot(TM) Client VM (build 1.4.0-beta-b65, mixed mode)


Prior to jdk1.4 beta (build 1.4.0-beta-b65), getClass().getResource
("myfile").getFile() would return the location of "myfile" which then could be
used to read "myfile". For e.g. it would return /C:/Documents and
Settings/myfile


But in jdk1.4 beta (build 1.4.0-beta-b65) getClass().getResource
("myfile").getFile() returns the location of myfile that has spaces translated
into %20 characters. So, now it returns something like /C:/Documents%20and%
20Settings/myfile This cannot be used as a valid file name in java.io.File,
or java.io.FileInputStream classes

Existing code that uses getClass().getResource("myfile").getFile() does not
work in jdk1.4 beta (build 1.4.0-beta-b65).

tClassGetResourceGetFileNameBug

File name of the resource /C:/Documents%20and%20Settings/akjain/DESKTOP/performa

java.io.FileNotFoundException: /C:/Documents%20and%20Settings/akjain/DESKTOP/per
formance/webster-dictionary.txt (The system cannot find the path specified)

  To run this program you will have to put (any text file/fake) "webster-
dictionary.txt" file in the directory where your java class is located.
