      • initialize

        public static boolean initialize​(String libraryName)
                          throws Exception
        Setup any APR internal data structures. This MUST be the first function called for any APR library.
        Parameters:
        libraryName - the name of the library to load
        Returns:
        true if the native code was initialized successfully otherwise false
        Throws:
        Exception - if a problem occurred during initialization

      • load

        public static void load​(String filename)
        Calls System.load(filename). System.load() associates the loaded library with the class loader of the class that called the System method. A native library may not be loaded by more than one class loader, so calling the System method from a class that was loaded by a Webapp class loader will make it impossible for other Webapps to load it. Using this method will load the native library via a shared class loader (typically the Common class loader, but may vary in some configurations), so that it can be loaded by multiple Webapps.
        Parameters:
        filename - - absolute path of the native library

      • loadLibrary

        public static void loadLibrary​(String libname)
        Calls System.loadLibrary(libname). System.loadLibrary() associates the loaded library with the class loader of the class that called the System method. A native library may not be loaded by more than one class loader, so calling the System method from a class that was loaded by a Webapp class loader will make it impossible for other Webapps to load it. Using this method will load the native library via a shared class loader (typically the Common class loader, but may vary in some configurations), so that it can be loaded by multiple Webapps.
        Parameters:
        libname - - the name of the native library
