AppServDELImpl

public class AppServDELImpl extends Object implements com.sun.enterprise.deployment.backend.DeploymentEventListener
This class listens to the deploy/undeploy events. On deploy, it investigates the deployment descriptors for web services. If web services exist, the application or stand alone module is demarcated persistently. This cache is used to discover the deployed web services artifacts in the repository. This removes the need to read all the deployment descriptors in the repository. On un-deploy, the information, if any, in the cache is removed.

Constructors Summary
public AppServDELImpl()
Default constructor.
Methods Summary
public voidnotifyDeploymentEvent(com.sun.enterprise.deployment.backend.DeploymentEvent event)
Listens to DEPLOY and UNDEPLOY events. On deploy, the cache is updated if the application or stand alone module has web services in it. For application, the ejb and web bundles with web services are identified. On un-deploy, the application or stand alone module is removed from cache.
