Even though I was able to resolve this
programmatically by setting the class type in the
Unmarshaller
Unmarshaller unmarshaller = new
Unmarshaller(RunDvpRequestVO.class);
unmarshaller.setMapping(mapping);
But now I am having a problem doing this through the
Spring FactoryBean. I want to obtain an instance of
the unmarshaller from the Spring FactoryBean.
Here is the code to get an instance of the
unmarshaller through Spring:
Unmarshaller unmarshaller = (Unmarshaller)
applicationContext.getBean("unmarshaller");
and the following is the entry in the Spring
configuration file:
<bean id="resolver"
class="org.springframework.xml.castor.CastorResolverFactoryBean">
<property name="mappingLocations">
<list>
<value>castor-mapping.xml</value>
</list>
</property>
</bean>
<bean id="unmarshaller"
class="org.springframework.xml.castor.CastorUnmarshallerFactoryBean">
<property name="resolver" ref="resolver"/>
</bean>
But now how do I specify the class type of the class
that I want to unmarshall to???
I looked at the online Javadoc for the Unmarshaller
class, but there is no
Unmarshaller.setClass(java.lang.Class c) method for
setting the class type. The only way I can pass in
the class type is via the Unmarshaller's constructor.
But I cannot call the constructor because I am
obtaining an instance of the unmarshaller through
Spring.
Is there another way to pass in the class type, maybe
via the Spring config file? How do I solve this
delima?
Thanks.
