avoiding import to base class

Hi,

I'm using hbm2java with a base class.

Code:

    <class name="com.wgh.Tenant" table="tenant" >
            <meta attribute="generated-class">com.wgh.base.Tenant</meta>
            <id name="tenant_id" column="tenant_id" type="long" unsaved-value="null">
                    <generator class="identity"/>
            </id>

            <many-to-one name="original_tenant_record" column="original_tenant_id" class="com.wgh.Tenant"/>

</class>

My problem is that since there is a relationship to itself, when hbm2java is run an illegal import is generated. Any suggestions how to eliminate this import?

My class:

Code:

package com.wgh.om;

public class Tenant extends com.wgh.base.Tenant {
}

Generated class:

Code:

package com.wgh.base;

import com.wgh.Tenant;
import java.io.Serializable;
import java.util.Date;
import java.util.SortedSet;
import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.lang.builder.HashCodeBuilder;
import org.apache.commons.lang.builder.ToStringBuilder;

/** @author Hibernate CodeGenerator */
abstract public class Tenant implements Serializable {
...
}

The line "import com.wgh.Tenant" causes cyclical inheritance. Appreciate any tips.

That is not cyclic inheritance!?

It is your baseclass that now refers to a subclass....that is normally messy - but legal java code?!

Remember you need to actually write the com.wgh.Tenant class before you can compile this!

If you don't want your base.Tenant refer the real Tenant then you can just use <meta attribute="property-type">com.wgh.base.Tenant</meta> for the original_tenant_record...but then you will probably get some weird problems with hibernate expecting it to be a Tenant and not a base.Tenant!

Hi,

You're right, the problem is different than I first thought.

The issue is actually that the generated class tries to import "com.wgh.Tenant" but there is a name conflict with the class itself. I'll change the name and see if this helps.
