I am sorry, I should have also given the mapping file. Here it is:
<?xml version="1.0"?>
<!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Object Mapping DTD Version
1.0//EN"
"http://Castor.exolab.org/mapping.dtd";>
<mapping>
<class name="Data">
<map-to xml="Data"/>
<field name="test" type="types.USStates">
<bind-xml name="test" node="element"/>
</field>
</class>
<class name="EnumTest">
<map-to xml="enumTest"/>
<field name="Data" type="Data">
<bind-xml name="data" node="element"/>
</field>
</class>
</mapping>
And the xml:
<enumTest>
<data>
<test>AK</test>
</data>
</enumTest>
Thanks for your help,
Ramesh.

I tried setting the mapping and it gave the following error. Maybe it
will help you, I did not understand what it meant:
java.lang.IllegalStateException: Java schema change: Class
types.USStates can no longer be constructed: types.USStates{file: [not
available]; line: 5; column: 9}
Thanks,
Ramesh.

Hi Ramesh,
have you set the mapping for the unmarshaller? (unmar.setMapping())
