public class ExtractingRoot
extends StandardRoot

If the main resources are packaged as a WAR file then any JARs will be extracted to the work directory and used from there.

Method Details

processWebInfLib

protected void processWebInfLib()
                         throws LifecycleException

Description copied from class: StandardRoot

Class loader resources are handled by treating JARs in WEB-INF/lib as resource JARs (without the internal META-INF/resources/ prefix) mounted at WEB-INF/classes (rather than the web app root). This enables reuse of the resource handling plumbing. These resources are marked as class loader only so they are only used in the methods that are explicitly defined to return class loader resources. This prevents calls to getResource("/WEB-INF/classes") returning from one or more of the JAR files.

Overrides:

processWebInfLib in class StandardRoot

Throws:

LifecycleException - If an error occurs that should stop the web application from starting

isPackedWarFile

protected boolean isPackedWarFile()

Overrides:

isPackedWarFile in class StandardRoot

stopInternal

protected void stopInternal()
                     throws LifecycleException

Description copied from class: LifecycleBase

Sub-classes must ensure that the state is changed to LifecycleState.STOPPING during the execution of this method. Changing state will trigger the Lifecycle.STOP_EVENT event.

Overrides:

stopInternal in class StandardRoot

Throws:

LifecycleException - Stop error occurred
