The Administrative Console

The Administrative Console provides control, monitoring and diagnostic functions for a running Weaver application.

The console presents both static and dynamic information.

The static information includes details of:

The version of the Weaver platform running
The Java version used to build Weaver
The applications running in the Weaver instance
Details of the Jar files being used by the application
Configuration information

The dynamic information includes details of:

Errors raised by the running applications
Statistics
The running JVM

In addition the console allows logging settings to be modified, and provides a file browser to locate and retrieve any of the files deployed in your application e.g. log files.

Accessing the Weaver Console

For an application that appears at the url:

http://www.myhost.com/myapp/

Its administrative console may be accessed at:

http://www.myhost.com/myapp/admin/

By default the administrative user has the following credentials:

Username	admin
Password	admin

The view component of the Weaver Console is built using JSPs. The first time you visit any given page after deployment will be significantly slower than subsequent access; as the first visit will cause the page to be compiled.
