Subject Re: How to create cayenne datamap on the fly
Date Sun, 08 Jul 2007 16:17:12 GMT
Hi Andrus,
thanks for the sample code.
Sorry for my stupid question :-D... yes.. i try to generate datamap on the
fly via servlet.
About point 2... i noticed (in the sample) that datamap xml file (obj-entity)
hasn't "className" attribute. So.. i think this is the main difference from
the "normal" datamap file and the one required for my scope. Is it the only
one... or i must take care about other differences?

Thanks again for you support.

D.
