how to add mdmjar references in the CE7.1 ide

hi Experts,

I have my application in CE 7.1 and trying to connect with the MDM. The JAVA API sca file is deployed in the server but i am getting the "java.lang.ClassNotFoundException: com.sapportals.connector.connection.ConnectionFailedException".

I have all my jars in the external library and The WD DC uses these jars in it's dependency part as build deploy and run time.

i tried to remove the deploy time but I got the error "java.lang.ClassNotFoundException: com.sap.mdm.commands.CommandException ".

In NW7.0 we need to add library refernce to the MDM4j.jar and for the connector. But in 7.1 this option is not there. SAP asked us to add DC dependency.

Any clue how my WD DC can refer these connector class at run time.
