JDBC Configuration ant task error

Hibernate version: 3.1.2

Hibernate Tools version: 3.1 beta 4

Name and version of the database you are using: Informix

I have created the following ant script to reverse engineer some of the tables in an Informix database:

Code:

project name="java" default="reverse" basedir=".">

   <target name="init">
      <property name="lib.dir" location="${basedir}/lib" />
      <property name="cfg.dir" location="${basedir}/cfg" />

      <property name="hibernate.config.file" location="${cfg.dir}/hibernate.cfg.xml" />
      <property name="hibernate.reveng.config.file" location="${cfg.dir}/hibernate.reveng.xml" />

      <property name="output.dir" location="${basedir}/output" />

      <path id="hibernate-classpath">
            <fileset dir="/opt/hibernate/tools/plugins/org.hibernate.eclipse_3.1.0.beta4/lib/hibernate">
               <include name="*.jar" />
            </fileset>

         <fileset dir="/opt/hibernate/tools/plugins/org.hibernate.eclipse_3.1.0.beta4/lib/tools">
            <include name="*.jar" />
         </fileset>
            <fileset dir="${lib.dir}/informix">
               <include name="*.jar" />
            </fileset>
         </path>

      <taskdef name="hibernatetool" classname="org.hibernate.tool.ant.HibernateToolTask">
         <classpath>
            <path refid="hibernate-classpath"/>
         </classpath>
      </taskdef>

   </target>
   
   <target name="reverse" depends="init">

       <hibernatetool destdir="${output.dir}">
         <jdbcconfiguration
               configurationfile="${hibernate.config.file}"
               revengfile="${hibernate.reveng.config.file}"
               reversestrategy="org.hibernate.cfg.reveng.DelegatingReverseEngineeringStrategy"/>

      </hibernatetool>

   </target>



</project>

When I run it using -debug for ant, I get the following output:

BUILD SUCCESSFUL
Total time: 2 seconds

Note, that I get a BUILD SUCCESSFUL. But, there is no output from the reverse engineering. Also, note that with the debug output, there are some Exception classes that get loaded. I have messed with this thing for awhile and have not a clue what is going on. I have assured that the config files all exist and messed around with the classpath.

Any help is greatly appreciated. I do hope this is just a stupid error on my part.

Thanks,
Jesse

what is in your reveng.xml ? cfg.xml ?

and you don't need to specify anything in reversestrategy if you dont use it.

The contents of hibernate.cfg.xml are:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
      "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

        <property name="hibernate.connection.username">impool</property>
        <property name="hibernate.dialect">org.hibernate.dialect.InformixDialect</property>
    </session-factory>
</hibernate-configuration>

And the contents of hibernate.reveng.xml are:

</hibernate-reverse-engineering>

Thanks!

and you are sure the casing matches what is in the database ?

(we should try and add autodetection on how the underlying database is doing these comparisons so it doesnt matter)

jmelendez · **Joined:** Fri Feb 11, 2005 2:13 pm **Posts:** 11

Yes. The files were actually generated and used by the Hibernate Eclipse plug-in. The reverse engineering worked there, but I was trying to get an ant task created for it insteat.

Thanks,
Jesse

max · **Posted:** Thu Feb 02, 2006 4:10 pm

well it doesnt really look like the hibernate tools is running at all - there should be some log output from it.

jmelendez · **Joined:** Fri Feb 11, 2005 2:13 pm **Posts:** 11

I beg to differ on that point. For example, if I change the "reverse" target in the above build.xml to:

Code:

   <target name="reverse" depends="init">

       <hibernatetool destdir="${output.dir}">
         <!-- jdbcconfiguration
               configurationfile="${hibernate.config.file}"
               revengfile="${hibernate.reveng.config.file}"
               reversestrategy="org.hibernate.cfg.reveng.DelegatingReverseEngineeringStrategy"/ -->


      </hibernatetool>

   </target>

I get the following output:

aaah dude...you don't list any exporters to run ;)

you just do "reverse engineering" and doesnt do anything with the output.

put a task in jira so i can make the task complain about no tasks to do.

Right on!
