Spring with Castor - Null Pointer Exception when initialising Application Context
- by babyangel86
Hi,
I'm trying to register my castor mapping files with spring and I appear to be getting a null pointer exception.
In my application context I have:
<bean id="xmlContext" class="org.castor.spring.xml.XMLContextFactoryBean">
<property name="mappingLocations">
<list>
<value>DistributionSamplerMappings.xml</value>
</list>
</property>
<property name="castorProperties">
<props>
<prop key="org.exolab.castor.xml.strictelements">false</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>
<property name="ignoreExtraElements"><value>true</value></property>
<property name="ignoreExtraAttributes"><value>true</value></property>
</bean>
Where DistributionSamplerMappings.xml lives in the same dir as the application context.
I've tried using the spring-xml jar 1.2.1 and 1.5.3. but none of them seem to help.
The exception being thrown back is:
SEVERE: Context initialization failed

I'm using Spring 2.5.6 and Castor 1.3.1.
Looking around I find I'm not the only one who has had this problem, but I don't seem to be able to find a solution.
Any help would be much appreciated.
