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
