JNDIs

Each context can be configured with a JNDI section automatically loaded by gCore. Following the stack of contexts, we can configure:

• the GHN Context
• the Service Context
• the port-type Context

While the first one is global for each node and its configuration is under the GHN manager responsibility, the others are service-specific and MUST be taken into consideration when developing a new gCore compliant service. Per each service, there are:

• one and only one ServiceContext
• several port-type Contexts, depending on the service architecture and needs

Both the Service Context and the port-type Contexts can be configured with a dedicated service element in the file called deploy-jndi-config.xml and placed in the etc folder under the service location.

Configuring the ServiceContext

$The ServiceContext....

At least, one port-type class in a gCore compliant service MUST:

• extend the GCUBEStartupPortType
• be declared with the parameter <parameter name="loadOnStartup" value="true"/> in the deploy-server.wsdd file under the etc folder of the service location

This port-type performs the ServiceContext initialisation. gCore recommends that only one port-type extends the StartupPortType. If two (or more) port-types extend the GCUBEStartupPortType, you have to be aware that your service context is initialised twice. This is an overhead but not an issue for the gCore initialisation procedure. However, it could be a problem if a service performs specific initialisation actions in the service context events (like the onReady() or onInitialisation() callback methods) that are supposed to be executed only once.
