Hi all,

I just created a new project using Hibernate3 and added the latest Hibernate Tools to it. I followed the instruction on installing them and how to use the hbm2java subtask in Ant. When running my gode-gen ant task I always run into an Exception.

Exception:

SCHWERWIEGEND: Method needsEqualsHashCode threw exception for reference $pojo in template pojo/PojoEqualsHashcode.vm at [1,5]
20.11.2005 14:14:21 org.apache.velocity.tools.generic.log.CommonsLogLogSystem logVelocityMessage
SCHWERWIEGEND: Method get threw exception for reference $templates in template pojo/Pojo.vm at [17,1]
org.hibernate.tool.hbm2x.ExporterException: MethodInvocationException while processing template Pojo. Invocation of method 'get' in class org.hibernate.tool.hbm2x.TemplateHelper$Templates threw exception class org.hibernate.tool.hbm2x.ExporterException : MethodInvocationException while processing template pojo/PojoEqualsHashcode.vm. Invocation of method 'needsEqualsHashCode' in class org.hibernate.tool.hbm2x.pojo.EntityPOJOClass threw exception class java.lang.NoSuchMethodError : org.hibernate.mapping.Property.isNaturalIdentifier()Z


The rest of the stack trace is a little much to post. So, can anybody help me with that???

Thanks,

Kimba

use the hibernate that comes with the tools for your ant task.
(the code generator is dependent on 3.1 code)

Hi,

Go to your eclipse plug-in folder and find the org.hibernate.eclipse_XXX folder. There is a lib folder in it use jars in this folder.
If you install Ecplise on f:\eclise and use HibernateTool 3.1.0 beta 1 then the path will look like this:

F:\eclipse\plugins\org.hibernate.eclipse_3.1.0.beta1\lib\hibernate

Please rate if it helped!

Thanks Max... I was running into the same exact problem as Kimba74 and then I used the hibernate3.jar file within

/HibernateTools-3.1.0.beta1 Folder/plugins/org.hibernate.eclipse_3.1.0.beta1/lib/hibernate

And the hbm2java works like a charm now!

Thank you!
