startDeployment

public void startDeployment()

This is called by the server's startup servlet which essentially informs us that the server's internal EJB/SLSBs are ready and can be called. This means we are allowed to begin registering types from deployed plugins.

This is called when this deployer service itself is starting up.

Throws:

Exception

public void pluginDetected(org.rhq.enterprise.server.core.plugin.ProductPluginDeployer.DeploymentInfo deploymentInfo)
                    throws Exception

registerPlugins

public void registerPlugins()

Registers newly detected plugins and their types. Only call this method when isReady is true. This is a no-op if we are not ready.
