Hi,

I'm having a devil of a problem that I've spent the good part of 2 days troubleshooting. Background:

Hibernate3 (jar dated December 11, 2005)
Hibernate Tools 3.1.0 beta2
Ant 1.6.5
Eclipse 3.1.1 M2

Using an ant definition for HibernateToolTask, if I run hbm2java with an attribute of "generics=true", I get an immediate build error that "Hbm2JavaExporterTask doesn't support the 'generics' attribute". I'm using Ant within Eclipse's jvm, and in Ant's classpath I've included all the jars from the org.hibernate.eclipse3.1.0.beta2/lib subdirectories.

No one else on the web seems to have had this problem, but for the life of me I don't see what I'm doing wrong. The obvious suspect would be a classpath problem, but I'm able to generate anything else I want to.

Here's my ant target (may have typos - I can't cut & paste):

<target name="gen-java">
<hybtool destdir="${source.root}">
<configuration configurationfile=${source.root}/hibernate.cfg.xml/>
<hbm2java generics="true"/>
</hybtool>
</target>


Oh, and I should mention that I can't use the Artifact Generation wizard because I have a custom reverse naming strategy.

you may want to double check the classpath and make sure there aren't any old HT distributions laying around.

the attribute generics have been replaced with the more correct jdk5="true" and in the newest release (part of jboss ide, but available as a seperate download) allows you to configure a custom namingstrategy in the ui.

He says he is using 3.1.0 beta2.

Maybe http://www.hibernate.org/hib_docs/tools/ant/index.html should/should not have 3.1 beta 1 at the top ?

The docs link http://www.hibernate.org/5.html#A13 says 3.1 beta 2, and the linked resource ( http://www.hibernate.org/hib_docs/tools/ant/index.html ) says there is still a @generics.

oh, and @ signs are back BTW ;)

hmm....weird, there should be beta2 docs there. in any case that will all be updated tomorrow ( i hope ;)

Thanks Max. "jdk5=true" works. But I must say, I've read just about every document on the web with the word "hbm2java" in it, and I did not see that attribute anywhere.

And I am using beta2. Thanks again everyone!

does hibernate-tools 2.x set support generics?

I got the h-tools 3 working, but it is still lacking in much of the functinoality that the 2.x toolset had

huh ? what functionallity are you missing !?

and no, the 2.x toolset does not support generics.

ok.

well I originally saw it wasn't making default equals/hashcode methods, but that's no problem, i just added in the meta attributes to do that.

my question is, does it handle the custom user types the same as before? I have my attributes declared like the following:



btw, i do love the hibernate code generation wizard in the ecilpse plug-ins.

default equals/hashcodes are bad - that is why h3 and latest h2 tools doesnt do it anymore.

and yes, usertypes will work perfectly - you of course just need to have them in the classpath so hbm2java can ask it what the return types are.
Nothing different between h2 and h3 tools there.
