CREATING JCo RFC Provider Service
The RFC enables the execution of predefined functions in a remote or local system. This is done by registering the server Program to the ABAP gateway and the service is technically based on the JCo. Based on JCo 2 API, this service dispatches the incoming RFC requests to Java Beans. The JCo RFC Provider registers itself on the gateway and listens for incoming RFC requests, they are dispatched to the Java Beans. The name of the Java Bean must be the same as the Remote Function Module name called and must be registered in JNDI .
Refer to SAP Note 1135947 - Bean not found
For new applications the Java Resource Adapter is the recommended way instead for JCo RFC Providers.
