following with some reference, i must include jboss-service-custom.xdt
when generete SAR descriptor.
but i have problem to looking for jboss-service-custom.xdt. where i cant get it? how it work with hibernate ?

I am using Hibernate2.1.2 with Jboss3.2.3 but I haven't heart about "xdt" thing, xdt is an extension of Xdoclet.
Just follow this everything must be fine........

But If you are using Xdoclet.
1. goto your-xdoclet-dir/lib
2. find this file xdoclet-hibernate-module-1.2b2.jar
3. extract it
4. you can find it in /xdoclet/modules/hibernate/resources
But this file is just a template to generate Hibernate-Jboss-Service-Description, you don't need to packed it in your SAR.
