[b]Need to access a file which is not specified in the classpath[/b]

Question

Hi everybody ,
I need your help to proceed with my application. I've tried accessing a file without setting it in Classpath using getResourceAsStream(..), but i'm getting an error.
error :
java.lang.NullPointerException
at java.io.Reader.<init>(Reader.java:61)
at java.io.InputStreamReader.<init>(InputStreamReader.java:55)
at abc.func(LoadProp.java:13)
at LoadProp.main(LoadProp.java:35)
Application :-
import java.io.* ;
class test
public void func(String file )
String thisLine ;
try
InputStream is = test.class.getClassLoader().getResourceAsStream(file);
System.out.println("File load successful");
BufferedReader myInput = new BufferedReader(new InputStreamReader(is));
while ((thisLine = myInput.readLine()) != null) {
System.out.println(thisLine);
catch (Exception e)
System.out.println("Inside Catch");
e.printStackTrace();
public class LoadProp
public static void main(String args[])
String testname = System.getProperty("propfile");
System.out.println(testname);
test t = new test() ;
t.func(testname) ;
System.out.println("End Main!") ;
Output:-
test.properties
File load successful
Inside Catch
java.lang.NullPointerException
at java.io.Reader.<init>(Reader.java:61)
at java.io.InputStreamReader.<init>(InputStreamReader.java:55)
at test.func(LoadProp.java:13)
at LoadProp.main(LoadProp.java:35)
End Main!
Anyone of you help me to get rid of this problem..
Thanks & Regards
BK

Answer 1

It has to be in the classpath for getResourceAsStream
to "get" it.So if your question is really about needing to read a file which is not in the classpath and won't be, then as long as you have the path to that file, just use FileInputStream to read it.
InputStream is = new FileInputStream(pathToFileHere);
