Cannot reverse engineer DB with hbm2hbmxml

Hi all,

I am trying to reverse engineer the DB and produce my .hbm.xml files using ant.
Here is my latest (of many) version of build.xml:

Code:

<project basedir="." name="MyBooks" default="compile">

    <property name="sourcedir" value="${basedir}/src"/>
    <property name="targetdir" value="${basedir}/bin"/>
    <property name="librarydir" value="${basedir}/lib"/>

    <path id="libraries">
        <fileset dir="${librarydir}">
            <include name="*.jar"/>
        </fileset>
    </path>

    <target name="clean">
        <delete dir="${targetdir}"/>
        <mkdir dir="${targetdir}"/>
    </target>

    <target name="compile" depends="clean, copy-resources, generate_files">
      <javac destdir="${targetdir}">
        <src path="${sourcedir}"/>      
             <classpath refid ="libraries"/>
      </javac>
    </target>

    <target name="copy-resources">
        <copy todir="${targetdir}">
            <fileset dir="${sourcedir}">
                <exclude name="**/*.java"/>
            </fileset>
        </copy>    
    </target>

   <taskdef 
     name="hibernatetool" 
     classname="org.hibernate.tool.ant.HibernateToolTask" 
     classpathref="libraries"/> 

    <target name="generate_files">
        <hibernatetool> 
    
          <jdbcconfiguration configurationfile="hibernate.cfg.xml"/> 
   
          <destdir="${sourcedir}/xml"/>

        </hibernatetool>
    </target>
           
</project>

I get the following error:

C:\Projects\Hibernate\MyBooks\build.xml:64: The <hibernatetool> type doesn't support the nested "hbm2hbmxml" element.

Any ideas?

Thanks,

Howard

your exception does not match the build file you have shown.

There is no hbm2hbmxml.

Sorry about that. I must have deleted it when cleaning out commented sections. It is:

Code:

<project basedir="." name="Hibe" default="compile">

    <property name="sourcedir" value="${basedir}/src"/>
    <property name="targetdir" value="${basedir}/bin"/>
    <property name="librarydir" value="${basedir}/lib"/>

    <path id="libraries">
        <fileset dir="${librarydir}">
            <include name="*.jar"/>
        </fileset>
    </path>

    <target name="clean">
        <delete dir="${targetdir}"/>
        <mkdir dir="${targetdir}"/>
    </target>

    <target name="compile" depends="clean, copy-resources, generate_files">
      <javac destdir="${targetdir}">
        <src path="${sourcedir}"/>      
             <classpath refid ="libraries"/>
      </javac>
    </target>

    <target name="copy-resources">
        <copy todir="${targetdir}">
            <fileset dir="${sourcedir}">
                <exclude name="**/*.java"/>
            </fileset>
        </copy>    
    </target>

   <taskdef 
     name="hibernatetool" 
     classname="org.hibernate.tool.ant.HibernateToolTask" 
     classpathref="libraries"/> 
 
<target name="generate_files">
    <hibernatetool> 
    
      <jdbcconfiguration configurationfile="hibernate.cfg.xml"/> 
   
   <hbm2hbmxml  destdir="${sourcedir}/xml"/>

    </hibernatetool>

</target>
           

</project>

hmm - are you sure you are using the latest/greatest ? hbm2hbmxml were not there in the inital versions...but that is really a long time ago...

I downloaded "org.hibernate.eclipse_3.1.0.alpha5.jar" and installed in the lib directory of the project. When I encountered my initial problems, I unjarred the .jar file and placed the following files directly in the lib folder:

1. hibernate-tools.jar
2. jtidy-r8-21122004.jar
3. velocity-1.4.jar
4. velocity-tools-generic-1.1.jar

I already had hibernate3.jar and my drivers there.

The structure looks like this:
MyProject
-lib
----hibernate-tools.jar
----jtidy-r8-21122004.jar
----velocity-1.4
----velocity-tools-generic-1.1.jar
----hibernate3.jar
----drivers, etc.

-src

-hibernate.cfg.xml

-build.xml

What do you think?

If you are using ANT inside Eclipse then you'll need to "tell ANT where to find the hibernate-tools.jar". This is done by:

Code:

clicking Window, Preferences..., Ant, Runtime, Ant Home Entries, then click Add External Jars...

If you are using Ant commandline then I think you can specify the jar using -lib <path>.

Hope this helps.

use something more recent than alpha5! ;)
