There were quite a few changes.  See the following:

Are you sure about this?  If I recall correctly, System.loadLibrary() 
worked pretty much the same in 1.1 as it does in 1.3, and the JavaDoc 
for loadLibrary() says pretty much the same thing in 1.1 and 1.3.

Are you aware that there are two different methods in the System class 
that can be used to load a library?  Perhaps you used load() and are 
now confusing it with loadLibrary().

    public static void loadLibrary(String libname)
        Loads the system library specified by the libname
        argument. The manner in which a library name is mapped
        to the actual system library is system dependent. 

    public static void load(String filename)
        Loads the specified filename as a dynamic library.
        The filename argument must be a complete pathname. 

BTW, loadLibrary() does not actually require that the DLL file be on 
the path.  The Windows Java runtime looks for DLLs in the directories 
specified by the system property "java.library.path".  The default 
value for this property is pretty much the same locations that Windows 
usually does, including the directory that contains the executable, the 
PATH, the Windows system and system32 directories, and a few others.

Unfortumately, the "executable" when you are running a Java program is 
"java.exe", so it is not very useful to load DLLs from the directory 
that contains it.  It would be nice if the DLL loading code would also 
look in a directory based on where the classes were loaded from.
