Hi Rikard
Are you using Castor XML directly on the EJB or on the ValueObject/View that
the EJB generates?
I am using Xdoclet with CMP2.0 which generates the Views/ValueObjects. Now,
I would now like to add XML input and output capabilities. eg:

You might also want to check out CMP2.0. It includes features like lazy

CMP2.0 is:

- easier to develop web applications (long transactions)
