Problems with persistance manager factory

Question

This method keeps hit a "Null pointer Exception" and i don't know why can
anyone help?
it may be a problem with the a setting in JBuilder 9, i just don't know.
public void getPersistenceManagerFactory(){
if(pmf==null){
Properties props = new Properties();
try{
props.load((getClass().getResourceAsStream("/kodo.properties"))); //
this is the line which is not working.
catch(IOException ioe){
throw new
JDOFatalInternalException("Datalink: getPersistenceManagerFactory():Could
load resource KODO",ioe);
this.pmf =
JDOHelper.getPersistenceManagerFactory(props);

Answer 1

How can put kodo.properties at the root of my class path then
it will probably be in C:\Jbuider\lib\ext
what is the name of that file that contains kodo.properties
if can find that i can add that the file.

My guess is that kodo.properties is not available at the root of your
runtime classpath. You may want to change the input stream as a
new FileInputStream (new File ("...."));
