HI
I am in the process of upgrading to Hibernate 3.1.3 and I am in the need of converting the existing custom velocity template to freemarker template as hibernate tools now use only freemarker template. I used the convertor provided in Freemarker site to convert my pojo.vm to Pojo.ftl.

But, with freemarker template, I am not able to use the expression - ${pojo.getPackageDeclaration($clazz)} as it says not valid. Hence I am forced to use ${pojo.getPackageDeclaration()} instead. But this will deny me the usage of clazz across my ftl file to fetch fields, scope and many other params.

So , pls let me know how to use the clazz object in freemarker template that will help me to use functions like clazz.getLocalFieldsForFullConstructor(), clazz.generatedName, clazz.getFields(),.

Thanks. A quick response is very much appreciated.

Hibernate version:
3.1.3
Mapping documents:
My Pojo.FTL (Built using Velocity to freemarker converter utility)
${pojo.getPackageDeclaration($clazz)}
// Generated ${date} by Hibernate Tools ${version}
${pojo.generateImports()}
${classbody}
