Hibernate version:3.1
Hibernate Tools version:HibernateTools-3.1.0.beta3
Database:Firebird 1.5

Hi everyone. I'm trying to generate a simple Schema from the POJOs, from a Firebird Schema. The tables are something like this:

Quote:

Table - TIPO_LEITO_TLT
ID_TLT
DESCRICAO

Table - LEITO_LTO
ID_LTO
ID_TLT
NUMERO

This is the revenge.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" >

<sql-type jdbc-type="BIGINT" hibernate-type="java.lang.Long" length="11"/>
<sql-type jdbc-type="VARCHAR" hibernate-type="java.lang.String"
length="80" />
<sql-type jdbc-type="FLOAT" hibernate-type="java.lang.Double" length="6"/>
<sql-type jdbc-type="TIMESTAMP" hibernate-type="timestamp" length="17"/>
</type-mapping>
<table-filter match-name="TIPO_LEITO_TLT" />
<table-filter match-name="LEITO_LTO" />
<table-filter match-name="ANUNCIO_ANU" exclude="true" />
<table-filter match-name="ANUNCIO_IMAGENS_ANI" exclude="true" />
<table-filter match-name="IMAGENS_IMG" exclude="true" />
<table-filter match-name="LEITO_IMAGENS_LTI" exclude="true" />
<table-filter match-name="TARIFARIO_TRF" exclude="true" />
<table-filter match-name="TIPO_IMAGEM_TPM" exclude="true" />

<table name="TIPO_LEITO_TLT">
<primary-key>
<generator class="increment"></generator>
<column name="ID_TLT" jdbc-type="BIGINT" property="id"
type="java.lang.Long" />
</primary-key>
<column name="DESCRICAO" jdbc-type='VARCHAR'
property="descricao" type="java.lang.String" />
</table>
<table name="LEITO_LTO">
<primary-key>
<generator class="increment"></generator>
<column name="ID_LTO" jdbc-type="BIGINT" property="id" type="java.lang.Long"/>
</primary-key>
<column name="ID_TLT" jdbc-type='BIGINT' property="idTipoLeito" type="java.lang.Long"/>
<column name="NUMERO" jdbc-type='VARCHAR' property="numero" type="java.lang.String"/>
</table>
</hibernate-reverse-engineering>

And this is the exception in Eclipse when I try to generate:

Quote:

Exception while generating code

Reason:
org.hibernate.console.HibernateConsoleRuntimeException: Could not create or find with one argument delegate constructor

Could not create or find with one argument delegate constructor
java.lang.ClassNotFoundException:
java.lang.ClassNotFoundException:

What is wrong in the revenge.xml?

Thanks in advance and Best Regards

I've dug deeper in the forum, and managed to find a post with my problem, in my hibernate tools version, the reveng strategy was not put by default as the Delegated one, so no constructor could be found by an empty reveng strategy. Sorry for the silly question. But I've seen that when I try to generate a bidiretional many-to-one/one-to-many relationship, I can't specify if I want the POJO relationship just for queries(not persistent) and a persistent column of the binding id persistent. How can I achieve such thing???

Thanks in advance
