Hey all,
Hibernate newbie, so forgive me if this is something I just may yet not understand. I'm using the middlegen-Hibernate-R5 plugin to generate hbm.xml files from an existing database. I've written a JavaTypeMapper to cast Binary types to byte[]. This, of course, does not work during deployment as it does not understand the byte[] 'type' from the XML.

Somewhere I came across the net.sf.hibernate.type.BinaryType, gave that a try and setting the hbm.xml 'type' field works, but using hbm2java it does not convert it to a byte[] as I had hoped.

Further I also found this article: http://www.hibernate.org/73.html which seems kinda what I thought net.sf.hibernate.type.BinaryType would do, but still involves modifying generated code.

Rather than trying to modify generated code (which really is a no-no in my opinion), has anyone solved this problem or have better/easier pointers to help get past this problem?

Thanky!

User types do not provide the information necessary for generation tools to perform the appropriate conversion(s) so you need to look to the tools. In the case of hbm2java it has a meta tag 'property-type' which should be able to help. Middlegen does not generate this particular meta tag at this point. Create a enhancement request in JIRA so I don't forget it.

if the UserType can be resolved by hbm2java then it will call it's getReturnedClass() and use that as it's type - should work IMO.

(but if it's tricky then the property-type can be used as a workaround ;)
