Msql and o8i - using a default value in an insert

Question

1. In an Oracle 8i Enterprise DB I have a primary key in table FOO called FOO_ID, it's SQL description is:
FOO_ID NUMBER DEFAULT TO_CHAR(sysdate, 'HH24MMSSMMDDYY') NOT NULL
1.5 I test via TOAD inserting a record into the DB without specifying FOO_ID, but specifying other values in the table row. I commit the data. When I commit the table correctly fills in FOO_ID with a time/date stamp per the above definition.
2. I run wtgpack and create an application which uses this table. I check the SQL code to make sure the column definition is copied to the snapshot which will be the basis for Oracle 9i Lite mobile DB on my laptop.
3. I run msync.exe and get the DB.
4. I run msql to make sure the data replicated ok. It did.
5. I run an INSERT statement not specifying a primary key hoping that the default will be used. For example,
"INSERT INTO FOO (FOO_TYPE) VALUES ('Test Type')";
I get the following error from msql:
[POL-3221] null key in primary index
The questions is, why isn't the O9iLite DB using the default value when creating the new record/row?
Thanks,
Z

Answer 1

Danny is spot on, but a little elaboration for the beginner:
childValue == "yes" asks whether these two are the exact same String object. There are times when that's true, but it's unlikely. Instead, use String equals() ( childValue.equals("yes") ) to ask whether the two have the same value.
With the simple class Danny suggests:
class Vessel {
   private boolean assessed;
   private int stenosis;
   public boolean isAssessed() { return assessed; }
}All you need in the loop is
Iterator vessels = vesselAssessed.values().iterator();
while (vessels.hasNext()) {
   Vessel vessel = (Vessel) vessels.next();
   if (vessel.isAssessed()) {
}
