hibernate.reveng.xml Clob Mapping

I currently am getting Clob objects mapped into java.lang.Objects in the reverse engineered code. I have done the following with the hibernate.reveng.xml file:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering SYSTEM "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

<hibernate-reverse-engineering>

    <type-mapping>
        <sql-type jdbc-type="CLOB" hibernate-type="CLOB"/>
    </type-mapping>

</hibernate-reverse-engineering>

Any item in the DB of type Clob still comes back as java.lang.Object in the generated code.

Anyone got any ideas?

Cheers.

the hibernate type should be "clob" not "CLOB"

and maybe the jdbc type is not CLOB when read from the database?

I have changed the hibernate type to clob and checked the DB, Oracle reports the column as type CLOB. After running the script again I get no errors but the resulting output does not change from java.lang.Object.

Code:

<property name="igsimgdata" type="java.lang.Object">
            <column name="IGSIMGDATA" />
        </property>
        <property name="igspimgdata" type="java.lang.Object">
            <column name="IGSPIMGDATA" />

hmm...if its alpha4 i think length also is required. cvs should work without length.
