Interface J2eeApplicationObject

All Superinterfaces:
DeployableObject
public interface J2eeApplicationObject
extends DeployableObject
J2eeApplicationObject is an interface that represents a J2EE application (EAR); it maintains a DeployableObject for each module in the archive.

Register a listener for changes in XPath that are related to this deployableObject.
DDBean[]
getChildBean(ModuleType type, String xpath)
Return a list of DDBean instances based upon an XPath; all deployment descriptors of the specified type are searched.
DeployableObject
getDeployableObject(String uri)
Return the DeployableObject of the specified URI designator.
DeployableObject[]
getDeployableObjects()
Return the all DeployableObjects in this application.
DeployableObject[]
getDeployableObjects(ModuleType type)
Return the all DeployableObjects of the specified type.
String[]
getModuleUris()
Return the list of URIs for all modules in the application.
String[]
getModuleUris(ModuleType type)
Return the list of URIs of the designated module type.
String[]
getText(ModuleType type, String xpath)
Return the text value from the XPath; search only the deployment descriptors of the specified type.
void
removeXpathListener(ModuleType type, String xpath, XpathListener xpl)
Unregister the listener for an XPath.
