Hello,

I am using Hibernate 2.1, and trying to use the SchemaExport task to automatically create some tasks. It doesn't seem to be working. Here's what I have in my build.xml:

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

<target name="schemaexport" description="Generate the SQL schema">
<schemaexport
config="extras/hibernate_export.cfg.xml"
quiet="no"
text="yes" drop="yes"
delimiter=";"
output="extras/schema-export.sql">
<fileset dir="src">
<include name="**/*.hbm.xml"/>
</fileset>
</schemaexport>
</target>

When I run this, I get:

BUILD FAILED
/home/chiral/mobilespace/build.xml:69: Schema text failed: Resource: chiralsoftware/mypackage/Site.hbm.xml not found

But the Site.hbm.xml file exists, in both the src and classes directories.

Does the SchemaExport task actually work? Or should I just use Ant's java task to execute the Hibernate schema export Java code directly, and not even bother with the Ant task? If someone could confirm that the schemaexport Ant task actually works, that would be much appreciated. And if it does work, I would love to know how to use it in this build file.

Thanks

I'm having the same problem...

Ant task:


hibernate.cfg.xml


error:

BUILD FAILED:
build.xml:26: Schema text failed: Resource: com/pg/webcc/contract/Contract.hbm.xml not found

Ah,
I found that by adding:


<pathelement location="webroot/WEB-INF/classes"/>


to my


<path id="class.path">
<fileset dir="webroot/WEB-INF/lib">
<include name="*.jar" />
</fileset>
<pathelement location="webroot/WEB-INF/classes"/>
</path>


things get happy ;)[/code]

I'm using Hibernate 3.0.5, and I can't get the ant task to execute as well.

Considering the example in the documentation (section 21.1.4 and 21.1.6) gives the examples:

<target name="schemaexport">
<taskdef name="schemaexport"
classname="org.hibernate.tool.hbm2ddl.SchemaExportTask"
classpathref="class.path"/>

<schemaexport
properties="hibernate.properties"
quiet="no"
text="no"
drop="no"
delimiter=";"
output="schema-export.sql">
<fileset dir="src">
<include name="**/*.hbm.xml"/>
</fileset>
</schemaexport>
</target>

<target name="schemaupdate">
<taskdef name="schemaupdate"
classname="org.hibernate.tool.hbm2ddl.SchemaUpdateTask"
classpathref="class.path"/>

<schemaupdate
properties="hibernate.properties"
quiet="no">
<fileset dir="src">
<include name="**/*.hbm.xml"/>
</fileset>
</schemaupdate>
</target>

Which is CLEARLY WRONG because classpathref="class.path" in the taskdef tag isn't defined within the target at all... Maybe someone could actually take the time to make the documentation correct?

I've tried what I think is every combination of classpath, pathelement, and path. The schemaexport task takes a fileset of the hbm.xml configuration files, but for some reason won't find any "classpath" to find the resources specified in the hibernate.cfg.xml file.

Another good question - why do I need to specify which hbm.xml files when the hibernate.cfg.xml file already specifies the <mapping resource="whatever.hbm.xml"/> mappings?

Use the regular forum.
