Parameters:   serviceAssemblyName - - name of the serviceassembly. Result/Status of this operation. throws:   Exception - if operation fails. startAllServiceAssemblies public void startAllServiceAssemblies()(Code) Bring all Service Assemblies to their desired states. This is done only during startup of the runtime, after all components have been brought to their desired states. Any failures that occur here are logged. Note: There is a requirement in the JSR208 specification that all Service Units must be initialized during startup of the runtime to eliminate the need for components to persist SU information. This means that for any SUs whose containing SA has a desired state of "Shutdown", the SU must be shut down after it is initialized. Here is the text from the JSR208 specification: JBI implementations MUST retain the running state of all service unit deployments, such that the system can be restarted from a shutdown or crash, and all deployments will be restored to their previous running state. During component restart, the implementation MUST perform the following to restore a service unit to its previous state: Started. The implementation MUST call init(), followed by start(). Stopped. The implementation MUST call init() to restore a service unit to the stopped state. Shutdown. The implementation MUST call init() followed by shutDown() to restore a service unit to the shutdown state. In all cases of state restoration, the implementation MUST call init() for all service units in the group being restored before any other life cycle methods for service units in the group are called In support of the above requirement, this method first initializes ALL deployed Service Assemblies. After that, all deployed SAs are brought to their desired states, either "Shutdown", "Stopped", or "Started". startServiceAssembly String startServiceAssembly(String saName) throws Exception(Code) Start a Service Assembly. All the Service Units are first initialized and then started.
