Merging maps in xml file for parent-child beans

[bharal]

G'day!

I'm trying to merge my maps in Spring. However, I'm coming across a problem with it.

So, here's the code (and yes, I'm using Spring 2.0):

<bean id="parent-bean" abstract="true">
		<property name="mapValues">
	      	<map>
	      		<entry key="key">
	      			<value>value</value>
	      		</entry>
	      	</map>
      </property>
</bean>

<bean id="child-bean" parent="parent-bean" class="some.class.here">
		<property name="mapValues">
	      	<map merge="true">
	      		<entry key="key2">
	      			<value>value2</value>
	      		</entry>
	      	</map>
      </property>
</bean>

Now, the problem is that at startup, I get this error:

org.springframework.beans.factory.BeanDefinitionStoreException: Line XXX in XML document from ServletContext
resource [/WEB-INF/spring-config/config-name.xml] is invalid; nested exception is org.xml.sax.SAXParseException: Attribute "merge" must be declared for element type "map".
Caused by:
org.xml.sax.SAXParseException: Attribute "merge" must be declared for element type "map".

Where, Line XXX is listed every time I have a merge=true definition. I can't see the problem - can anyone else?

Thanks,
Andrew

That's probably an issue of the doctype declaration in your file. You probably still reference the spring-beans.dtd instead of the spring-beans-2.0.dtd.

If you are going to change this, it might be worth going for it and using XML schema instead.
