How do I integrate WebLogic Components into my legacy systems?
There are several ways to do this. The simplest way is to make a component invoke API calls into the legacy systems (e.g. CICS, IMS). These calls can be programmed in, or “plugged-in” at runtime as Business Policies. By setting runtime properties, you can change the way a component may call an external interface. Another way is to map the component to a legacy database, in effect giving that database a distributed, object-oriented Java interface.
