Subject Re: AW: Need to add one generic get/set attribute in Project API
Date Fri, 14 Sep 2007 10:07:37 GMT
  I am adding reference through java code
  where conn is my connection object, but I m getting Null Pointer exception here
  The code for addReference in Project class is
   public void addReference(String referenceName, Object value) {
        synchronized (references) {
            Object old = ((AntRefTable) references).getReal(referenceName);
            if (old == value) {
                // no warning, this is not changing anything
            if (old != null && !(old instanceof UnknownElement)) {
                log("Overriding previous definition of reference to " + referenceName,
            log("Adding reference: " + referenceName, MSG_DEBUG);
            references.put(referenceName, value);
  According to below code it seems that it is searching that value in some existing memory...
  and if it doesnt get that then it throws exception and if it gets that but with different
value then it override that value.....
  I would appreciate clearification... on this method...
  Use set/getReference ;-)
