XmlRpc installation

Eclipse still doesn't recognize the following statement in a java file after I added XmlRpc as \Eclipse\puilgins\org.apache.xmlrpc-3.0:

XmlRpcClientConfigImpl

import org.apache.xmlrpc.client.XmlRpcClient;

import org.apache.xmlrpc.client.XmlRpcClientConfigImpl;

Is there any specific installation procedure I have to follow? Thanks,
