[manish86b]

Hi,
i am using the following artifacts.
spring-data-commons-core-1.2.1RELEASE.jar
spring-data-mongodb-1.0.1.RELEASE.jar
mongo-java-driver-2.7.3.jar

Trying to build a simple REST based web app using spring data and mongodb.

My spring web config file contains..

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.Mongo Template">
<constructor-arg ref="mongoDbFactory" />
</bean>

</beans>


Issue1 : I have a warning stating 'Unable to locate spring Namespace handler for the element mongo:db-factory of schema namespace 'http://www.springframework.org/schema/data/mongo'

Issue2 : On starting the server i get the following exception stating that mongoTemplate instantiation failed.

I was able to fix this problem by just upgrading my spring framework core jars from 3.0.5 to 3.1.1.
Thanks.
