CHAPTER 4 New features in EAServer 5.1
What’s New 19
Systems Management
EAServer 5.1 includes support for the Simple Network Management Protocol
(SNMP), which includes an SNMP master agent from J.AgentX. This replaces
the functionality provided previously by Java AgentX.
The graphical user interface has also been updated. The Web Console plug-in
allows you to browse the MBeans and services installed on either your local
server or a remote server using a Web browser. You can add and modify
MBeans and services using wizards, rather than by editing XML. The console
also allows you to set properties and invoke methods on the MBeans, and start,
stop, restart, and refresh services. For more information, see Chapter 13,
“Using Systems Management,” in the EAServer System Administration Guide.
The EASDefault Web application
In EAServer 5.1, all Web pages that are not part of a Web application are added
automatically to the EASDefault Web application. You configure the
properties for EASDefault the same as you do for other Web applications.
Initially, the context path for EASDefault is “/”, and the WEB-INF directory is
created under $JAGUAR/html. When users access http://host:port/, EAServer
invokes the welcome page of the Web application whose context path is “/”.
Because the EASDefault welcome page is index.html and the context path is
“/”, EAServer invokes $JAGUAR/html/index.html. To change this behavior,
you can either:
• Change the EASDefault welcome page, or
• Change another Web application’s context path to “/” to display its
welcome page.
To configure most server-level properties for servlets and JSPs, you use the
Web Application Properties dialog box, instead of the Server Properties dialog
box. For details, see Chapter 21, “Creating Web Applications,” and Chapter
22, “Creating Java Servlets,” in the EAServer Programmer’s Guide.
