Don't know what is wrong.

Don't you also need a Mongo driver bean???

I am also wondering what

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

is about. Are you missing a jar.

Also, I believe the stacktrace you posted is not the entire stack trace.

Scroll to the bottom of the stack trace and work your way up till you hit your first "Caused by" from the bottom. That would be the root real cause.

But here is an example from a sample project I created a little bit ago

    <mongo:mongo id="mongo"
            host="#{mongoDbProperties['mongo.host']}"
            port="#{mongoDbProperties['mongo.port']}">
      <mongo:options
         write-number="1"
         write-timeout="0"
         write-fsync="true"/>
    </mongo:mongo>

    <mongo:db-factory id="mongoDbFactory"
                      dbname="#{mongoDbProperties['mongo.database']}"
                      mongo-ref="mongo"
                      username="#{mongoDbProperties['mongo.user']}"
                      password="#{mongoDbProperties['mongo.password']}"/>

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

    <mongo:repositories base-package="com.blah.repository.mongodb"/>

    <mongo:mapping-converter base-package="com.balh.domain.mongodb">
    </mongo:mapping-converter>

We also externalized some property values into a .properties file

Thanks

Mark Spritzler, First of all thank you very much for replying,
Sir the stack trace that I Posted here is all I get, I ran the application again and checked that.
This is from an example which I got online here : http://www.mkyong.com/mongodb/spring-data-mongodb-hello-world-example/
I am not getting why others can run it and I can not.

[Mark Spritzler]

Because your configuration doesn't match what is in that blog.

As the example I posted and in the blog there is

<mongo:db-factory

Which is no where in your configuration.
