Thanks to those who responded, but we've resolved our issue. For the
curious:
Situation:
CMP Entity Bean with attributes that have a primitive type, e.g.:
double foo;
The table the entity bean was mapped to contained rows which did
not have a value for the "foo" column.
When retrieving these rows, Weblogic 4.51 did not throw any exceptions,
and a getFoo() would return 0.0. I don't know if this was the default
value that foo initialized to, or if it was assigned by the CMP routines.
Resolution.
We resolved the problem by using the primitive wrapper classes.
Fortunately,
Weblogic's default CMP handles them just fine. When using:
Double foo;
The call to getFoo() returned null for the rows that did not have this
value.
I don't know if this behavior is even addressed by the spec, so I can
only comment as to what Weblogic did.
