The C++ version -of ACE is a large object-oriented network programming toolkit which contains over 125,000 lines of C++ code and -uses advanced C++ features like templates.</P> -<P>The goal of converting ACE from C++ to Java is to provide a portable programming toolkit with a similar interface -and functionality to the original version of ACE. This allows new and current users of C++ ACE an easy transition -to Java and also adds significant value to programming concurrent Java networking applications. Note that applications -written using Java ACE can communicate seamlessly over sockets with applications written using C++ ACE.</P> -<P>The following diagram illustrates the architecture of the Java version of ACE:</P> -<CENTER> -<IMG SRC="java-ace.gif" ALIGN="BOTTOM" BORDER="0"></CENTER> -<P> -The Java ACE architecture has fewer components than the diagram illustrating the architecture for the <A HREF="http://www.cs.wustl.edu/~schmidt/ACE-overview.html">C++ -version of ACE </A>. This reduction in size occurs for two reasons. First, the Java Virtual Machine (JVM) handles -many of the portability issues provided by C++ ACE. Therefore, the OS adaptation layer is unnecessary. Second, -Java doesn't support certain OS features provided by Win32, UNIX, and other OS platforms that C++ ACE is ported -to. For example, Java doesn't support shared memory and memory-mapped files and therefore the memory management -wrappers (such as <CODE>Mem_Map</CODE> and <CODE>Shared_Malloc</CODE>) are omitted from Java ACE.</P> - -<P>The process of converting ACE from C++ to Java provided us with an excellent source of insights on the strengths -and weaknesses of using Java for industrial-strength software system frameworks.
