Hi all,

I have very specific problem.
I am using Maven (hibertnate3:hbm2java)
to do some reverse engineering.

Everything looks OK but I don't want to use
.hbm.xml e.g. I need to define classes somewhere else.

Up to now as defined in .xmb.xml it continuously ask for the java
files to generate POJO's but as described above I don't want to generate them
in this way. Is there some work around for this problem (except ANT)

P.S. I need to use Maven for Code generation, not the Eclipse.

Thanks,
Ned

I think everyone here would only recomened using ant or the eclipse plug in to do your reverse engerneared pojo generation. personaly i'd recomend and ant script like this:
Code:
<project name="goFurtherTools" basedir="../" default="hibernateCodeGen">
   <property name="tools.dir" value="tools" />
   <property name="src.dir" value="src" />
   <property name="web.dir" value="web" />
   <property name="test.src" value="test" />
   <property name="lib.dir" value="${web.dir}/lib" />
   <property name="build.dir" value="build" />
   <property name="test.dir" value="${build.dir}/test" />
   <property name="webapp.name" value="goFurther" />
   <property name="gen.dir" value="gen" />

   <property environment="env" />

yes - i recommend the ant version.

I got an email from the maven guy who apparently did the maven port but I haven't had time looking into what it does (besides it is not actually seem to be doing what I want a maven port to do ;) I shuold get around looking at it.

Thanks

Max if you have some interesting news please reply.

As I wrote I don't want to prepare (pregenerate) pojos in the way .xbm.xml does. Rather I need solution that will just define tables, columns, target directory and/or any other needed parameters and generate pojos there.

Regards,
Ned

sorry - i don't understand your question ?!

you don't want mapping files nor classes ?!

OK, here is my code

if
my Sample.xbm.xsl
looks like:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

<class name="clpath.Sample" table="Sampletable">
<meta attribute="extends">clpath.NewPOJO</meta>
<meta attribute="class-description">
Pojo for entity Sample.
</meta>

<id name="id" column="ID">
<meta attribute="field-description">Primary Key</meta>
<generator class="sequence">
<param name="sequence">Sample_SEQ</param>
</generator>
</id>


</class>

</hibernate-mapping>

Maven would always complain that can not find ID (column in Sample.java)


If I don't create clpath.Sample.java with integer ID (MANUALY)
my new clpath.Sample.java (Pojo) with EJB annotation will be not generated.

I am searching to do the same without making Sample.java with ID

The same class called EchoMessage in Hibernate sample looks like:



package com.genuitec.hibernate;
// Generated by MyEclipse - Hibernate Tools



/**
* EchoMessage generated by MyEclipse - Hibernate Tools
*/
public class EchoMessage extends AbstractEchoMessage implements java.io.Serializable {

// Constructors

/** default constructor */
public EchoMessage() {
}

/** minimal constructor */
public EchoMessage(Long id) {
super(id);
}

/** full constructor */
public EchoMessage(Long id, String msg) {
super(id, msg);
}

}


OR

If I am wrong should this file be generated by eclipse somehow in the some previous step?

You haven't specified a type for the id; so hard for the tooling to generate the correct type ;)

I guess something like:

<id name="id" type="long" column="id">
