Did you place your form-bean inside form-beans?
<form-beans>
<form-bean
name="CustForm"
type="org.apache.struts.action .DynaActionForm" dynamic="true">
<form-property name="custName" type="java.lang.String"/>
<form-property name="typeName" type="java.lang.String"/>
<form-property name="typeNameDesc" type="java.lang.String"/>
<form-property name="confirm" type="java.lang.boolean"
initial="true"/>
</form-bean>
</form-beans>
