here is schemaexport target in my buildfile

<target name="schemaexport">
<path id="class.path">
<fileset dir="C:/Programfiler/hibernate-2.1">
<include name="**/*.jar" />
</fileset>
<pathelement location="${properties.dir}/bin" />
<fileset dir="${mysql.lib.home}">
<include name="**/*.jar" />
<include name="**/*.zip" />
</fileset>
</path>
<taskdef name="schemaexport"
classname="net.sf.hibernate.tool.hbm2ddl.SchemaExportTask" classpathref="class.path" />

<schemaexport properties="hibernate.properties" quiet="no" text="yes" drop="no" delimiter=";"
output="${basedir}/schema-export.sql">

<fileset dir="bin">
<include name="**/*.hbm.xml" />
</fileset>
</schemaexport>
</target>

The schema-export.sql file is created without errors ,but no tables are created in my database.

http://www.hibernate.org/hib_docs/reference/html/toolsetguide.html#toolsetguide-s1-5 text=yes means don't export to the database.

thx
but the only thing that happend was that the schema-export.sql file is now blank

Is there any log output? Are your properties set up correctly?

I have no log output
hibernate.properties file:

#define query langugage constants/function names
hibernate.query.substitutions true 1, false 0, yes 'Y', no 'N'

When I solved my saving to database problem, also on this forum, I figured out what was wrong;
In hibernate.properties I found:

#auto shema export
hibernate.hbm2ddl.auto create

Changing from create to update solved all my problems, both that of saving to db and exporting chema to db.
