Eclipse (3.3.1) - Hibernate Tools plugin - structured hbm.xml editor does not resolve external entity references kept in an external DTD file that is referenced in the hbm.xml file

[Reference - Hibernate Tools forum - Title - Eclipse,Hibernate Plugin, External DTD, Hibernate XML Editor] - Initial posting below:

The below external reference to globals DTD (per pg. 137 in Java Persistence w/ Hibernate book) works when I run hbm2ddl as an ant task. I added the HibernateTool plugin into Eclipse (3.3.1.1). In the Hibernate tools perspective, I've created a console configuration & specified under "options" the entity resolver: "org.hibernate.util.DTDEntityResolver". No errors so far.

When I open the Role.hbm.xml file (Java Perspective) using "Open with.." "Hibernate 3.0 XML Editor" the external dtd references are not resolved in the Hibernate 3.0 XML Editor window.

Dir. struct. is - src/com/t0/{Role.java, Role.hbm.xml, IRglobals.dtd}
Class struct. is - classes/com/t0/{Role.class, Role.hbm.xml, IRglobals.dtd}

------------------- My globals dtd is IRglobals.dtd:

<!ENTITY SeqS10000I1C20
'<param name="parameters">start with 10000 increment by 1 cache 20</param>'
>
------------------------
My Role.hbm.xml is:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"
[
<!ENTITY % IRGlobals SYSTEM "classpath://com/t0/IRGlobals.dtd"> %IRGlobals;
]>
<hibernate-mapping package="com.t0">
<class name="Role">

<id name="roleId" type="long">
<generator class="sequence">
<param name="sequence">ir_role_seq</param>
&SeqS10000I1C20;
</generator>
</id>

<property name="name" type="string" length="10" unique="true" not-null="true" ></property>

</class>
</hibernate-mapping>
------------------------
If I replace the external reference to the DTD w/ an inline reference to the entity, then the Hibernate 3.0 XML editor resolves it. Since I have several hbm files & several global refs in my project, I'd prefer to just reference the IRglobals.dtd in all my hbm files.

Any suggestions on how to get the references from an external global dtd file resolved in the Hibernate 3.0 XML editor would be appreciated.
