Hi,
have a look at the classes generated, and you'll notice that for every
member Castor creates a second member with a has_ prefix. It's by using
the additional information available that Castor is able to marshal
'null' values.
I don't think there's a way to achieve the same by the means of using a
mapping file. I might be wrong, though.

For the elements min-net-cap and xpns-shrng-id-nb I should see
null in the POJO but I don't see that. I see that when the POJOs are
created they have 0 assigned to them.

Subject: Re: [castor-user] Default values
Hi,
can you supply us with a scenario of what you are trying to do. Iow,
show us example code, a mapping file fragment, etc. ?

Hi there,
I have castor mapping for a pojo. I'm using Object types instead of
primitive type for Long and Ints. What I'm seeing is that where ever
myt XML doesn't have value for that element which corresponds to the
member by default it is setting it to 0. Is there any way I can
specify in the mapping file that use null as default when there is no
value ?
Thanks
