 Post subject: [Solved] Classpath protocol broken for hibernatetool task

I'm running hbm2ddl via the hibernatetool Ant task. I appear to be running into this issue http://forum.hibernate.org/viewtopic.php?t=927396&highlight=entityresolver, namely that the EntityResolver is not able to handle the "classpath://" protocol.

As far as I can makeout, this issue has been fixed. I can see the fix in the source code. I am using the binary for Tools, but the code in the repository for the RC1 looks like it is setting the entity resolver.

I am using the latest HibernateTool (3.2.0.GA) jars. I have also tried explicitly setting the "entityresolver" attribute of annotationconfiguration (as shown below).

Can anyone help? Has anyone else been able to use this ant task with the "classpath://" protocol?

Richard

Hibernate Tools version:
Hibernate 3.2.0.GA

Ant script
Code:
...

<path id="hibernate-tools-lib">
      <path location="${hibernatetools.lib.dir}/hibernate-tools.jar" />
      <path location="${hibernatetools.lib.dir}/hibernate3.jar" />            
      <path location="${hibernatetools.lib.dir}/freemarker.jar" />
      <path location="${lib}/postgresql-8.2.505.jdbc4.jar" />
      <path location="${hibernatetools.lib.dir}/hibernate-annotations.jar" />
      <path location="${hibernatetools.lib.dir}/hibernate-commons-annotations.jar" />
      <path location="${hibernatetools.lib.dir}/dom4j-1.6.1.jar" />
      
   </path>

...

<target name="export-schema"
         description="Generates a database create script">
   
      <hibernatetool destdir="${database.scripts}">
      
         <classpath>
            <pathelement location="${jar.dir}" />
            <pathelement location="${lib.dir}/mvanamibia-dim.jar" />
            <pathelement location="${lib.dir}/joda-time-1.4.jar" />
         </classpath>
      
         <annotationconfiguration
            configurationfile="${basedir}/resources/hibernate/hibernate.cfg.xml"
            entityresolver="org.hibernate.util.DTDEntityResolver" />
            
         <hbm2ddl
            drop="false"
            export="false"
            create="true"
            outputfilename="create_schema.ddl"            
            format="true" />
      
      </hibernatetool>
   
   </target>
...

I've solved this problem. There were two things wrong with my configuration:

Firstly, the first path element 'hibernate' was missing in the entity declaration, which now reads: <!ENTITY mappings SYSTEM classpath://hibernate/mappings.cfg.xml">

Secondly, the parent folder of 'hibernate' ('resources') was not declared in the classpath for the hibernatetool task, which now includes: <pathelement location="${basedir}/resources" />

However, the resulting error message (taken from my original post) couldn't be more misleading:

Code:
org.dom4j.DocumentException: unknown protocol: classpath Nested exception: unknown protocol: classpath


This cost me a lot of time, so I will report this in Jira.
