Problem with reverse engineering

Hi all

Im very new to hibernate. And im just exploring some of the features of it.
I want to generate the bean files via the hibernate tools reverse engineering feature using Ant. But it doesn't seem to work. Its not giving me an error neither is it generating the files i require. Any help would be appreciated.

Hibernate version 3 :
Hibernate tools version 3.2.2 Beta:

Database oracle 10g/9i

Heres the build.xml file

Code:

<project name="MyProject" basedir=".">

<path id="toolslib">
 <path location="lib/hibernate-tools.jar"/>
 <path location="lib/hibernate3.jar"/>
 <path location="lib/freemarker.jar"/>
 <path location="lib/classes12.jar"/>
</path>

 <taskdef name="hibernatetool"
          classname="org.hibernate.tool.ant.HibernateToolTask"
          classpathref="toolslib"/>
          
 <target name="reveng.hbmxml"
         description="Produces XML mapping files in src directory">
         
  <hibernatetool destdir="${basedir}/src">
  
   <jdbcconfiguration propertyfile="${basedir}/helloworld.db.properties"
                      revengfile="${basedir}/hibernate.reveng.xml"/>
   <hbm2hbmxml/>
   <hbm2cfgxml/>
   
  </hibernatetool>
  
 </target>
 
</project>

and heres the hibernate.reveng.xml file (As you can see all i need is the tables of one schema)

Code:

<?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>
<schema-selection match-schema="ABS_INP"/>
</hibernate-reverse-engineering>

And this the property file.

Code:

hibernate.dialect = org.hibernate.dialect.OracleDialect
hibernate.connection.driver_class = oracle.jdbc.driver.OracleDriver
hibernate.connection.url = jdbc:oracle:thin:@XXX.XXX.XX.XXX:XXXX:XXX
hibernate.connection.username = XXX
hibernate.connection.password = XXX

when i run ant in the root directory this is the output i get
------------------------
Buildfile: build.xml

BUILD SUCCESSFUL
Total time: 0 seconds
-------------------------

Additonally heres the folder structure

ROOT_DIR
-hibernate.reveng.xml
-helloworld.db.properties
-build.xm

-LIB
--classes12.jar
--freemarker.jar
--hibernate3.jar
--hibernate-tools.jar

-SRC

Thanx in advance

1) is your shcema name ABS_INP and do you have permissions to read the schema metadata?

2) try and add/edit a log4j.properties and enable debug and you should get some info on what the tool is actually reading.

Hi max tx for the reply

I found out the problem. It was with the ant build file. If any one is interested in the answer let me know and ill post it.
