    Hi all,

    Sorry, newbie posting here. I've read all the docs and played with all of
    the tutorials, but now I need some advice. The question is whether to code
    directly to the PB or to code to ODMG or JDO. I'm attracted to the simplicity
    of the PB but am concerned about the management of 1:n or m:n relationships
    between objects. The documentation indicates that when using the PB, the 
relationships
    between collections of objects would need to resolved manually using the link()
    and unlink() calls. The document also seems to indicate that this would not be
    the case if ODMG were employed. Can anyone iterate over the good, bad and
    ugly of one method verses the other? Looking for the voice of experience here.

    Thanks

Subject: Problem reading a clob object



Hi All,

    I'm using oracle 8i database.
    The table has a column with the data-type as CLOB which we are using to
store xml data.
    It is mapped to String data type in the java object.
    I have no problem inserting  xml data with this mapping. But when i try
to fetch the record using persistence broker, Its failing to retrieve the
data.
    Can anybody throw some light on this problem?

Thanks
Rajani
