Connection caching enhancements
EAServer 4.1 adds connection cache support for Oracle OCI 9 connections to
Oracle databases, and Sybase Open Client™ Client-Library™ connections to
highly-available Adaptive Server Enterprise databases.
jagtool enhancements
The administration automation tools, jagtool and jagant, have been enhanced
with several new commands for EAServer 4.1, including:
• Several new commands to configure Java Message Service entities.
•The
compilejsp command to compile JavaServer Pages.
•The
configure command to execute XML configuration files.
•The
exportconfig command to create XML configuration files.
For more information, see Chapter 12, “Using jagtool and jagant,” in the
EAServer System Administration Guide.
Servlet and Web application interface changes
The servlet filter interface required by EAServer 4.1 has changed from version
4.0. The
setFilterConfig method is no longer supported (as of version 4.1); it has
been replaced by the
init and destroy methods.
For Web application lifecycle event listeners, the interfaces
javax.servlet.ServletContextAttributeListener and
javax.servlet.http.HttpSessionAttributeListener are both new for EAServer
version 4.1. The corresponding interfaces from EAServer version 4.0, where
“Attributes” was plural, are not supported in EAServer 4.1.
For more information on servlet filters and Web application lifecycle event
listeners, see Chapter 23, “Using Filters and Event Listeners,” in the EAServer
Programmer’s Guide.
