    • Method Detail

      • 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()
        Description copied from class: StandardRoot
        Returns true if and only if all the resources for this web application are provided via a packed WAR file. It is used to optimise cache validation in this case on the basis that the WAR file will not change.
        Overrides:
        isPackedWarFile in class StandardRoot
        Returns:
        true if the application is served from a packed WAR file
