SchemaExport: class not found

Hi

when I run the SchemaExport.bat file, I get errors about persistent class not found. Fair enough - but how do I tell SchemaExport where my class files are (is there a configuration parameter for this path)?

Thanks,
Peter

CLASSPATH comes to mind ,)

Er, ja, CLASSPATH - thanks! Feel a bit silly not to think of the most obvious path when dealing with Java...

One thing though, if I include a "jar" of my classes in the classpath, then I get a null pointer exception when I run SchemaExport - I need to include a path which includes the actual classes.

eh no.

just need to specify the mapping files you want to run with

Hmm. Well it definitely does not work for me when I only include the mapping file (I get the class not found exception), I need to include the class files too. I am using Hibernate 2.1.6 by the way (if that has any bearing on this).

(Sjovt - kan se du bor i Danmark).

you ofcourse need to specify your classes location via CLASSPATH and then specify the hbm.xml files on the command line to do this stuff.

(ja, Danmark er stedet ,)

I am using the schemaexport ant task and it also cannot find the bean class files - I get error:
C:\build.xml:220: Schema text failed:
net.sf.hibernate.MappingException: persistent class
[store.model.team.Person] not found

I wish the schemaexport ant task allowed specifing the classpath.

Below is the fragment from my ant file.

Code:

<target name="exportmodeltoDB" depends="" description="exports the model to DB using Hibernate's schemaexport" unless="Hibernate.properties">
        <path id="path.models">
            <fileset dir="out/testmodels/team">
                <include name="**/store/model/team/*.class"/>
            </fileset>
        </path>

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

        <schemaexport properties="Hibernate.properties"
                      quiet="no" text="no" drop="no" delimiter=";">
            <fileset dir="out/testmodels/team">
                <include name="**/store/model/team/*.hbm.xml"/>
            </fileset>
        </schemaexport>
    </target>

Not sure why hibernate2.jar in the ant/lib directory would cause this to fail but I am just happy it is working now that I explicitly make all the jars available from the ant classpath.

never put stuff in ant/lib - its an ANTi-pattern that prevents classloading to work.
