Database Reference
In-Depth Information
Table Editor enables database-independent definition of tables in terms of the fields (or col-
umns) and key fields. Table indexes can also be defined for specific fields or combination of fields.
Similarly, the type of table buffering and the corresponding settings can also be defined. For a spe-
cific database environment, the table-related information stored in the Java Dictionary (which is
imported into that database environment) is used to create the physical tables in that environment.
Dictionary perspective addresses the following tasks:
◾
Create Dictionary projects with or without a connection to the SAP component model.
◾
Create in the Java Dictionary platform-independent database objects like tables and indexes.
◾
Create in the Java Dictionary user-defined global data types like simple and structured data
types.
◾
Map automatically predefined data types to corresponding JDBC data types.
◾
Create transportable archives.
◾
Deploy archives.
◾
Perform table-related operations like deleting and renaming.
11.2.2.1.4 J2EE Perspective
J2EE perspective provides various tools that are required for uniform access to the development
resources within different J2EE project types. J2EE perspective provides views that enable visual-
ization of the J2EE projects in the J2EE Explorer or the J2EE DC Explorer for DC-based projects
in the JDI. It provides the logical view of the relevant project structure and is available as the
starting point for the main development activities like creating or editing of the corresponding
development objects.
EJB Module Project
groups together all of the Enterprise JavaBeans (EJB)
resources that are combined into a Java Archive (JAR) file along with the deployment descriptors
for the final deployment.
Web Module Project
groups together all of the Web resources that are
combined into a Web Archive (WAR) along with the deployment descriptors for the final deploy-
ment. Enterprise Application Project groups together all of the J2EE resources in a J2EE applica-
tion that are combined into an Enterprise Archive (EAR) for the final deployment.
J2EE perspective also provides an alternative diagrammatic view of the declarative steps within
a project using graphical editing tools. Diagram views are useful in complex projects to display
components and their relationships to each other.
EJB Editor enables easy access to create and edit the individual components of the EJBs (Session
Beans, Entity Beans, and Message Driven Beans). Starting from the overview page, it navigates to
the bean class and to the corresponding components and the home interfaces of the EJB.
JSP and HTML Editors enable easy access to create and edit Web resources. In addition to
the syntax highlighting, code completion, etc., these editors also support preview functionality.
J2EE perspective addresses the following tasks:
◾
Create J2EE projects with or without a connection to the SAP component model.
◾
Wizard support for defining and creating EJBs, namely, Session Beans, Entity Beans, and
Message Driven Beans.
◾
Wizard support for defining and creating Web resources like HTML pages, JSPs, Servlets,
and listeners.
◾
Configure the J2EE application using deployment descriptors.
◾
Create archives (JAR, WAR, and EAR).
◾
Deploy archives.
