When I code in Spring, I always use annotations, and always get stuck when it comes to xml based configuration. Right now, I'm stuck at a problem which is probably a very simple thing. I'd appreciate if you could help me out on this.

Have a great day!
An IllegalAccessError
in compiled code (not involving reflection) usually means a version mismatch: Client code was compiled against a version of the dependency where a member had a more permissive access modifier. Update your Maven dependencies.
(Since this is a very old question that got recently bumped: The versions involved are all obsolete and should be upgraded to modern versions, which should resolve the problem.)
!. Changes in Xml
spring-servlet.xml you can also change name with spring-servlet.xml to yourProjectName-servlet.xml
http://www.springframework.org/schema/data/mongo
http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
change to 1.1
http://www.springframework.org/schema/data/mongo
http://www.springframework.org/schema/data/mongo/spring-mongo-1.1.xsd
<mongo:mongo host="localhost" port="27017">

2. Put Four Jars OR Get From Maven
/Test/WebContent/WEB-INF/lib/mongo-java-driver-2.10.1.jar
/Test/WebContent/WEB-INF/lib/spring-data-commons-1.5.1.RELEASE.jar
/Test/WebContent/WEB-INF/lib/spring-data-commons-core-1.3.1.RELEASE.jar
/Test/WebContent/WEB-INF/lib/spring-data-mongodb-1.3.1.RELEASE.jar
3. In Dao/Service/Controller you can call these connection to Autowired
@Autowired
private MongoTemplate mongoTemplate;
@Autowired
private MongoOperations mongoOperation;
