Question

I have some *.hbm.xml files that are placed in the same folder at the hibernate.cfg.xml file. Now, I want to map some other *.hbm.xml files that are in a subfolder of this folder. How could I do it? Thanks!

here’s part of my hibernate.cfg.xml:

   <hibernate-configuration>         <session-factory name='MySessionFactory'>              <!-- some hibernate properties here -->                <!--This below works fine-->              <mapping resource='A.hbm.xml'/>               <!--This doesn't-->              <mapping resource='/dir/B.hbm.xml'/>          </session-factory>    </hibernate-configuration> 

This is part of my Ant file:

        <target name='generateHibernateSql'>          <taskdef name='SchemaExportTask'             classname='org.hibernate.tool.hbm2ddl.SchemaExportTask'         >             <classpath>                 <pathelement location='${build.classes.main.dir}'/>                 <pathelement location='${base.configuration.hibernate.dir}'/>                 <path refid='build.classpath.lib'/>             </classpath>         </taskdef> 

here’s my folder structure

${base.configuration.hibernate.dir}    | hibernate.cfg.xml    | A.hbm.xml    |--dir    |---| B.hbm.xml ${build.classes.main.dir} 

[Edit]

I have first tried and failed as Maurice suggested, changed the line to

 <mapping resource='dir/B.hbm.xml'/> 

still gives the same error:

Schema text failed: Could not parse mapping document from resource dir/B.hbm.xml 

and then I went on to try adding into my schemaexpoert as Mark suggested. It then wouldn’t even find my ‘A.hbm.xml’ anymore. Giving off the error:

Schema text failed: Could not parse mapping document from resource A.hbm.xml 

My SchemaExportTask now looks like:

        <SchemaExportTask             config='${base.configuration.hibernate.dir}\hibernate.cfg.xml'             quiet='no'             text='no'             drop='no'             delimiter=';'             create='yes'             output='${dist.database.dir}\schema-export.sql'         >             <fileset dir='${base.configuration.hibernate.dir}'>                 <include name='**/*.hbm.xml'/>             </fileset>         </SchemaExportTask>

The conclusion is that I was just really stupid. It had nothing to do with being in a different directory. I got confused because I was changing two things at once testing phase and then I blamed it all on the innocent ‘directory change’. Sorry for wasting everyone’s time.

If anyone is interested, here was what happened. I did some XSLT translation using a local DTD file, and specified the local DTD file with a relative path in my XSL file. But I put the generated hbm.xml files into a difference directory — hence SchemaExportTask cannot find the DTD file anymore and failed to parse the new hbm.xml files. And for some stupid reason, I thought the following completely different error messages meant the same thing…. Thanks a lot to Mark for reminding me that people wrote error messages for a good reason! Adding fileset still doesn’t work now, but I now know to read error meassages…I’m sure I’ll fix it soon. =.=”

For general Hibernate usage I agree with change Maurice suggested but thought I would give more of an explanation. Hibernate mapping files are loaded as resources from the classpath. As you have ${base.configuration.hibernate.dir} on your classpath you must give the path of the mapping file relative to this therefore the front / should be removed.

For using the schema export tool from ant the docs say that you should define the mapping files as a fileset rather than expect them to be found on the classpath. See
