Hi all,

I'm new in using hibernate in eclipse. I'm using Hibernate tools to generate Hibernate XML Mappings(hbm.xml). May I know how can I exclude all those fields name start with "_" in my table?
For e.g :
I have table Employee, with fields:
- empid,
- name,
- date_join.
...etc
I only want to generate the fields without "_". how can I do that ? Thanks for your response and suggestions.

the easiest i can think of is to write a custom reveng strategy that simply returns false for columns with a '_' in the method excludeColumn(...)

the other way is to use reveng.xml and explicit exclude all columns that you dont want.

Thanks max for the quick reply. I started to write a user strategy in myeclipse. This is my source.

package com.proj.product.commons.eo.revengtest;

import org.hibernate.cfg.reveng.DelegatingReverseEngineeringStrategy;
import org.hibernate.cfg.reveng.ReverseEngineeringStrategy;
import org.hibernate.cfg.reveng.TableIdentifier;

public class MyTest1 extends DelegatingReverseEngineeringStrategy {
public MyTest1(ReverseEngineeringStrategy delegate) {
super(delegate);
}

public boolean excludeColumn(TableIdentifier identifier, String columnName) {

System.out.println("columnName Name = '"+ columnName + "'");

if (columnName.contains("_")) { return false; }
return super.excludeColumn(identifier, columnName);
}

I can compile it. After that, I try to set in the Hibernate Code generation,
In main tab,
package : com.proj.product.commons.eo.revengtest
reveng.strategy I put : com.proj.product.commons.eo.revengtest.MyTest1
when I click "Run" , I got an error :
Exception while generating code, "Count not create or find com.proj.product.commons.eo.revengtest.MyTest1 with one argument delegate constructor."

are you using Hibernate Tools in a normal Eclipse or are you using the Hibernate Tools provided by MyEclipse ?

If running from within myeclipse their might be problems because of them bundeling a different and "mutated" version of the tools so it makes a difference in what to look after.

If you are running standalone this should definitly work assuming that class is in the classpath.

I downloaded the Hibernate Tools from "http://download.jboss.org/jbosside/updates/development" and running in myeclipse. Is that consider "mutated" version ?

May I know how can I get rid of that error if I want to run my custom Hibernate Strategy class in myelipse ? Or what is your suggestion to run the custom strategy class ? Thanks advances for your response.

The "mutation" i'm referring to is the version that MyEclipse contains. It is Hibernate Tools but they changed bits and pieces (and I don't know precisly which) thus there might be classloading issues when you use their version together with the real Hibernate Tools from hibernate.org.

I would appreciate if you could try and run it from a plain eclipse + hibernate tools (from us) and let me know if it is still a problem.

If it is still a problem then there is an Hibernate Tools issue; if it is not then its a compability issue created by MyEclipses' mutated version of hibernate tools.

thanks again for your quick response. The problem solved.

I used myeclipse and hibernate-tools-3.2.0beta8. It is working with the previous source.

What I did was, add the classpath correctly in Hibernate console configuration. e.g : /<Source file>/build/classes.

ah ok, so it was "just" a classpath issue. Good.

btw. in b9 we will just use the classpath of the project so the problem would not have occured.
