Access KM using API as predefined user

Question

Hello, dear experts!
Currently I am going to use KM as file storage for my application. I want to prevent direct access to KM content for all users and allow them to upload and download files only using my application.
The problem is:
I use not context of current user but some user found in UME.
IUser user = UMFactory.getUserFactory().getUserByLogonID("Administrator");
com.sapportals.portal.security.usermanagement.IUser ep5User = portalUserFactory.getEP5User(user);
context = new ResourceContext(ep5User);
When I try to operate KM (for instance create new folder) I get error: "User <Administrator> is not authenticated"
But user "Administrator" has all rights to access KM.
Is it possible to access KM using API as different user? Or is there another way to solve the problem?
Best regards,
Anton.

Hi, Praveen!
Thank you for your answer. Your code works fine!
But when I created my own service user "service_user" under Content Management  -> Utilities -> System Principals I cannot get resource context even after restarting servlet engine.
I get an exception java.security.PrivilegedActionException: com.sapportals.wcm.repository.ResourceException: User management exception: Could not get service user "service_user".
This user has the same permissions as "cmadmin_service".
Also user with the same name was created in UME.
May be I should execute some additional administrating task?
Best regards,
Anton.
