Using RIDC API we can execute UCM Services.

HOW TO   CHECKIN,CHECKOUT,UPDATE,SEARCH,DELETE,CREATE USERS,GROUPS IN ORACLE UCM FROM JAVA/J2EE APPLICATIONS
USING REMOTE INTRODOC (RIDC API's)

 Below is the sample code for talking to Oracle UCM via RIDC like how to checkin a file into UCM repository
checkout a content from UCM, update an existing content item,how to perform a search and display the results,
how to delete a content item and all of its revisions from UCM repository,How to create a security group ,creating local users (of-course no use in 11g and later revision UCM),How to read a text file which is in UCM repository and display the content and etc..

Here in this code I am using Oracle UCM 10g ,we can use any version of the UCM (bcoz  the UCM services are always same)

Below is the code and  the jar for this is oracle.ucm.ridc-11.1.1.jar  download it and add it in your IDE.

I thought it would be helpful for some beginners Thanks everybody.
