Hi there,
I am using Castor 1.2 jars and following the link at
http://www.castor.org/spring-xml-intro.html
and config looks like
------------------------------
<bean id="xmlContext" class="org.castor.spring.xml.XMLContextFactoryBean">
<property name="mappingLocations">
<list>
<value>vsearch-mapping.xml</value>
</list>
</property>
<property name="castorProperties">
<props>
<prop key="org.exolab.castor.indent">true</prop>
</props>
</property>
</bean>
<bean id="marshaller"
class="org.castor.spring.xml.CastorMarshallerFactoryBean">
<property name="xmlContext">
<ref local="xmlContext" />
</property>
</bean>
<bean id="unmarshaller"
class="org.castor.spring.xml.CastorUnmarshallerFactoryBean">
<property name="xmlContext">
<ref local="xmlContext" />
</property>
</bean>
---------------------------------------
when I start my tomcat server, I get the following exception trace
----------------------------------------

------------------------------------
I checked the source code, the following code line in
XMLContextFactoryBean cannot seem to find the mapping file correctly
even though its lying on my classpath under
WEB-INF/classes/com/abc/def/castor/mapping folder.
URL mappingResource = getClass().getClassLoader()
.getResource(mappingLocation);
--> this line returns a null mappingResource.
I have tried changing.. the property from
------------------
<property name="mappingLocations">
<list>
<value>vsearch-mapping.xml</value>
</list>
</property>
-----------------------
to
-----------------------
<property name="mappingLocations">
<list>
<value>classpath:vsearch-mapping.xml</value>
</list>
</property>
-----------------------
but I still get the same problem.
Any pointers will be much appreciated, I have wasted a lot of time
trying to figure this thing out..
