4. Finally, once login is successful, and the Session object populated with
the appropriate information, we can redirect the flow of control to another
page on our server, indicated by the successpage string variable:
res.callPage(successpage, req).
3.5.4 Accessing Domino data in Linux with Java
There are several mechanisms for Java programs to access Domino data,
Domino services, or data in other database management systems, such as:
  Domino Objects for Java through the lotus.domino package included with
the NCSO.jar or notes.jar. The Domino objects represent and can be used
to manipulate Domino data, such as item values, components, such as
databases and views, and services, such as user registration functions.
  The Java Native Interface (JNI) used to call C or C++ API functions or
programs. The Lotus C or C++ Domino and Notes APIs can be used to
manipulate Domino data and services at a more granular level than what
is provided by Domino objects.
  The Lotus Script Extender (LSX) toolkit and its Java Adapter. The LSX
toolkit lets LotusScript developers create custom objects in C++ and call
them from LotusScript. The Java Adapter provides the facilities to call
those objects from Java. Since the language used to create the objects is
C++, those C++ programs can make calls to the Domino and Notes APIs
or other APIs to access data and services.
In this Redbook, we focus on using the Domino objects classes to access
Domino data and services. For complete information about the Lotus C and
C++ APIs, and the LSX toolkit, visit the Developer Central Web site at:
http://www.lotus developer.com
.
The Domino Objects class architecture is based on a conceptual containment
model, where the container defines an object s scope. A container object is
always used to access the objects it contains. For example, we use a Session
object to get Database objects, and a Database object to create Document
objects.
Since one Domino object may be contained by several others, a full
containment diagram is beyond the scope of this redbook. However, some of
the key containment relationships are shown Figure 71 on page 94.
