SchemaUpdate and Annotations

Err, this is an odd question, but what happens to SchemaExport/SchemaUpdate with Hibernate3 and annotations? They used to take XML mapping files as input but as far as I can see, there is no way to generate XML files when using annotations (i.e. the mapping is read directly from annotations). Do we not need Schema* anymore for some reason?

Also, I noticed that Hibernate3 RC1 shiped with SchemaExport/SchemaUpdate still refering to Hibernate2 files. I assume this is a bug?

Thanks,

we have a new ant task that handles that. will be released soon.

what do you mean they refer h2 files ?

The batch files contain references to hibernate2.jar. What are we supposed to do until the Ant task is released? Is it currently impossible to export the schema if we are using annotations?

Thanks,

I have tried SchemaExport with annotations like below and it works.

Code:

    Configuration config = new AnnotationConfiguration().
    addPackage("a.b.c")
    .addAnnotatedClass(Foo.class)
    .addAnnotatedClass(Baz.class)
    .setProperty("hibernate.dialect", "org.hibernate.dialect.OracleDialect")
    .setProperty("hibernate.connection.driver_class", "oracle.jdbc.driver.OracleDriver")
    .setProperty("hibernate.connection.url", "jdbc:oracle:thin:@mymachine:1521:orcl")
    .setProperty("hibernate.connection.username", "me")
    .setProperty("hibernate.connection.password", "my")
    .setProperty("hibernate.connection.pool_size", "1");
    
    SchemaExport schExp = new SchemaExport(config);
    schExp.setDelimiter(";");
    schExp.setOutputFile("HibSchema.sql");
    schExp.create(true, false);

Is it the right way of exporting schema or we have to wait for new ant task?

that is what the new ant task does.
