What is the service startup policies in JOnAS ?

Service startup policies

JOnAS will try to start declared services in the order in which they appear in the list except for the depmonitor service which is always started at the end. If some services require other ones (even non declared in the list), service requirements will be started first.

To simplify the declaration of JOnAS services and to ensure that all service requirements are fulfilled, some services declare explicitly their dependencies in order to start them automatically.

Mandatory dependencies beetwen JOnAS services

A link between two services means that a service requires another one.

• registry and jmx services can be omitted from the list because they are automatically launched.
• As an example, starting the web service involves the startup of the security service.
  Declaring the web service in the list of JOnAS services without declaring the security service may be a solution.
• As an example, starting the resource service involves the startup of the wm and the jtm services.
  Declaring the resource service in the list of JOnAS services without declaring the wm and the jtm service may be a solution.
