Choose the J2EE (Java 2 Platform, Enterprise Edition) specification
level for your WebFacing application. If you are using WebSphere Application
Server 5, you can choose J2EE level 1.3 or 1.2. If you are using WebSphere
Application Server 3.5.6 or 4.x, choose J2EE level 1.2.
J2EE 1.3 is
recommended for WebSphere Application Server 5. J2EE 1.3 offers advantages
such as:
- Automatic handling of UTF-8 datastreams: In previous versions of WebFacing
or when using J2EE 1.2, UTF-8 support must be set manually.
- Data compression: Data compression improves WebFacing performance by reducing
the bandwidth required to transfer data to the end-user's browser.
Note: - J2EE 1.2 uses servlet specification 2.2 and JSP specification 1.1
- J2EE 1.3 uses servlet specification 2.3 and JSP specification 1.2
- Features such as Servlet Filters and Life Cycle Listeners are not available
with J2EE 1.2
