Hi,


I am using hibernate tools 3.2.4.ga plugin in my eclipse. I am generating pojo's and hbm's using eclipse, but I am unable to generate hbm file for tables with composite primary key.
Please suggest me what I need to do to generate these hbm's.I am getting the following exception. org.hibernate.tool.hbm2x.ExportException :
Error while processing entity: Data with template hbm/hibernate-mapping.hbm.ftl

I'm using composite primary keys, too, but reverse engineering runs just fine here.

Maybe the "Generate basic typed composite ids" setting in your code generation configuration is different, I have that checked.
I'm also using explicit <primary-key> sections in hibernate.reveng.xml. Maybe something is wrong in your hibernate.reveng.xml.

I have checked "Generate basic typed composite ids" while Hibernate Code Generation, but still I am getting the same Exception

You need to show the stacktrace and/or relevant reveng.xml setup.

Without it I got no idea.

HI Max,

I am giving here the contents of my hibernate.reveng.xml file and full stack trace for errors. Another detailed information on errors I have to give via a Screen Shot, but I don't find any way to attach it here.

Please try to help me on below details


Contents of hibernate.reveng.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

<hibernate-reverse-engineering>
<table-filter match-schema="ECSTEST" match-name=".*"/>
</hibernate-reverse-engineering>

My Schema ECSTEST contains the tables having Composite Primary Key
