Hibernate version: 2.1

I am trying to use Ant and hbm2ddl's SchemaExportTask and am getting an error because hbm.xml's are not found.

Can anyone give me some advice?

Thanks

----------------------------------------------------------------------------------

TaskDef:

<taskdef name="schemaexport" classname="net.sf.hibernate.tool.hbm2ddl.SchemaExportTask" classpathref="classpath" />

----------------------------------------------------------------------------------

Task:

<target name="schemaexport" depends="hibernate">
<schemaexport config="${basedir}/src/main/hibernate.cfg.xml">
<fileset dir="${src.dir}" includes="**/*.hbm.xml"/>
</schemaexport>
</target>

----------------------------------------------------------------------------------

hibernate.cfg.xml :

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">

<hibernate-configuration>

<session-factory>
<!--properties for jdbc connection here
removed for forum post-->

<mapping resource="info/matthewryan/faq/entity/Category.hbm.xml"/>
<mapping resource="info/matthewryan/faq/entity/Faq.hbm.xml"/>
</session-factory>

</hibernate-configuration>

Hi!

I’m using the Schema Generator with the hibernate.properties configuration file, not the hibernate.cfg.xml. I think I did this because I got the same error message as you.

Create a hibernate.properties file and change your target to something like this:

Code:
<target name="schemaexport" depends="hibernate">
   <schemaexport config="${basedir}/src/main/hibernate.properties">
      <fileset dir="${src.dir}" includes="**/*.hbm.xml"/>
   </schemaexport>
</target>

Hope this helps

I changed the target to this:

Code:
<target name="schemaexport" depends="hibernate">
   <schemaexport properties="${basedir}/src/main/hibernate.properties">
      <fileset dir="${src.dir}" includes="**/*.hbm.xml"/>
   </schemaexport>
</target>

and I got this message:


Code:
[schemaexport] (cfg.Configuration                         255 ) Could not compile mapping document
[schemaexport] net.sf.hibernate.MappingException persistent class [info.matthewryan.faq.entity.Category] not found
[schemaexport] at net.sf.hibernate.cfg.Binder.bindClass(Binder.java:85)

This is the target I use:

Code:
<target name="schema" depends="codegen, compile" description="Generate DB schema from the O/R mapping files">
        <taskdef name="schemaexport"
            classname="net.sf.hibernate.tool.hbm2ddl.SchemaExportTask">
            <classpath>
                <pathelement location="${build.dir}/classes" />
                <path refid="project.classpath"/>
            </classpath>
        </taskdef>
       
        <schemaexport properties="${basedir}/resources/hibernate/config/hibernate.properties"
            quiet="no"
            text="no"
            drop="no">
            <fileset dir="${map.dir}">
                <include name="**/*.hbm.xml"/>
            </fileset>
        </schemaexport>
    </target>



I think this issue is because the net.sf.hibernate.tool.hbm2ddl.SchemaExportTask needs a reference to compiled classes in addition to the jar files, which is set in line 5 in my target

Adding the classpath for the classes fixed that error.

The Ant build script runs without error, the DDL file is written to disk.

However the file is empty.......

Any ideas?
