Hi,

I want to assign a primary key while generating the pojo using hibernate.reveng.xml file by the ant tool.

My hibernate.reveng.xml file looks like this:
----------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering
SYSTEM "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >
<hibernate-reverse-engineering>
<table-filter match-name="VW_.*" exclude="false"/>
<table-filter match-name=".*" exclude="true"/>
<table catalog="TD20_QA2_Master_443" schema="trd0nedbo" name="VW_UI_PROMO_PLAN_PROD_LOCATION">
<primary-key>
<key-column name="plan_id"/>
</primary-key>
<column name="LOCATION_ID" jdbc-type="0" property="locationID"/>
<column name="primary_DC_name" jdbc-type="1" property="primaryDCName"/>
</table>
</hibernate-reverse-engineering>
-----------------------------------------------------
I tried to generate pojo's using
ant -verbose gen

It is throwing error like:

.....
....
org.xml.sax.saxparseexception: Element type "primary-key" must be declared.
......
.......
I don't know why? Even I checked it in the DTD, the element "primary-key" exists.

show the full stacktrace...should just work.

This is that I get when try to generate pojo's using ant.

E:\TrueDemand_USA\tools\hibernate-tools-sqlsvr>

what version of the tools are you running with ?

did you try and verify the xml with a xml verifier to see more precisly why the xml parser thinks you have a non well formed xml ?

Ya, I have verified with xml verifier(xml shell), it tells that the xml file is valid and well formed.

The versions of the tools are
Hibernate Version: 3.0
Ant Version: 1.6.5

the version number im interested in is the version of hibernate tools...
