The following target doesn't work:

Code:

    <target name="hibernate_to_java"
       description="Generate .java from .hbm files."
       depends="hibernate-acer-tl_anagrafica_audit"
       >

    <taskdef name="hbm2java"
        classname="net.sf.hibernate.tool.hbm2java.Hbm2JavaTask"
        classpathref="lib.class.path"/>

       <hbm2java config="${config.dir}/hbm2java.xml"
          output="${java.export.dir}"
       >
          <fileset dir="${xml.export.dir}">
               <include name="**/*.hbm.xml"/>
          </fileset>
      </hbm2java>
   </target>

and causes the following error:

Code:

        at org.apache.tools.ant.launch.Launcher.main(Launcher.java:90)

but the following target works perfectly !
Both target are from the same build.xml file and have the same classpathref set to ${lib.class.path}.
I'm stuck!
Of course I don't want to list all the xml mapping files and I'd like to use Ant's fileset feature with Hbm2JavaTask.

Code:

   <target name="alt-hbm2java" description="Generate ValueObject From Mapping Files">
      <java classname="net.sf.hibernate.tool.hbm2java.CodeGenerator" classpathref="lib.class.path">
         <arg value="--output=${java.export.dir}"/>
         <arg value="${xml.export.dir}\it\tlasf\db\audit\hibernate\model\Action.hbm.xml"/>
      </java>
   </target>

Please help me.
Thanks in advance.

The task you are using looks find as its about the same as the version we use in the tools example. It is likely to be a path issue.

But if it were a path issue, since the path is the same for both targets, the only reason for the failure could be that the Hbm2JavaTask class uses more libraries than CodeGenerator class. And if this is true, I'd like to know which are these libraries I need to add to the classpath.

Thanks again for your help.

Get the tools package from the example page and have a look. It works fine and will provide the basis for a solution.

I ran the tools package and all target work except the hbm2java one: I got the same error as in my build.xml.

I don't know what to do! I don't think there is anything particular in my environment:

What does your lib.class.path look like? What jars are included in the directories that are in that path?

The problem will end up being a environment issue, so as ugly as it is here is my environment setup script for the tools demo.

rem This is a basic environment script for the Hibernate Example.
@set ClassPath=D:\jdk1.4.2\lib\tools.jar;.;D:\apps\apache-ant-1.5.4\lib\ant.jar;D:\apps\apache-ant-1.5.4\lib\xercesImpl.jar;D:\apps\apache-ant-1.5.4\lib\xml-apis.jar
@set Path=D:\jdk1.4.2\bin;D:\jdk1.4.2\jre\bin;C:\WINNT\SYSTEM32;C:\WINNT;D:\cygnus\cygwin-b20\H-i586-cygwin32\bin;D:\apps\apache-ant-1.5.4\bin
@echo %ClassPath%
@echo %Path%
@set JAVA_HOME=D:\jdk1.4.2
@set ANT_HOME=D:\apps\apache-ant-1.5.4

I found the problem! You were all right: it was a classpath issue.
In my classpath (see below) I am including all jars in ${lib.common.dir}/hibernate and guess what ? There was an older hibernate-tools.jar renamed to _hibernate-tools.jar that actually was loaded before the good one. Me stupid!
