I've posted the stackTrace below, however, I was able to get past the error. I've
been working out of a book which describes interfaces for ejb2.0 and think I was
following an example for a remoteHome interface. I changed the getPropertyTypes
method to findAllPropertyTypes. OpenEJB seemed to like it better, however, my
application didn't.
Here's a briefing in case the group can help.
I'm returning a Collection from the method findAllPropertyTypes with which I thought I
might be cute and return all values for the record within a "ValueObject" or
"ViewHelperObject". The Collection returns but when I go to access the VO I get a
ClassCastException. What I came to find is that the object is no longer the VO but
rather my IPropertyTypeRemote object with a handle to my VO as pk=VO within each
object of the Collection. So using the Employee example on the OpenEJB website I
tried to pull the VO out by using the IPropertyTypeRemote.getPrimaryKey(). This again
threw a ClassCastException.
Is this due to the declaration within my Bean for retrieving primary keys? public
Integer findPrimaryKey(Integer i); If so how do you ever get ahold of all the data
for a table or specific row? SessionBeans?
TIA
Graham
