各位高人，谁知道怎样将Java代码编译成本地的二进制代码

[Norwaywoods]

给出这种技术的名字，或者网页都可以。谢谢！

[takecare]

javac
java.sun.com

[Norwaywoods]

能不能具体一点呀！

[Norwaywoods]

我还是自己回答吧：
JIT

[goldencode]

哈哈，
好象IBM的visualAge 也可以。

[xiaofenguser]

听说sun有一种原生码编译器

[Norwaywoods]

能不能说具体一点，最好是免费的东西。

Excelsior JET 3.0完全可以！！！并且它的个人版是免费的。

Excelsior JET 3.0, Standard Edition is the fast track solution for compilation of self-contained Java applications to native code.
Excelsior JET transforms your Java applications into conventional Microsoft Windows executables that work faster, consume less memory, and are much more resistant to reverse engineering by third parties.

Superior Application Performance. Excelsior JET makes your Java programs run at the speed of C/C++ programs through the extensive use of classical optimizations and object-oriented optimizations carefully adapted to Java.
Superior Code Protection. Excelsior JET helps you protect your intellectual property: instead of Java class files, extremely easy to reverse engineer, your end users receive highly optimized native code executables that are much less comprehensible.
Superior Scalability. Elimination of the virtual machine and run-time compilation from the execution process, extremely low heap overhead, and automatic sharing of code and data between processes at the operating system level dramatically reduce the memory footprint of your Java applications.
Easy Deployment. The JetPack utility packages your application files into a self-installing archive. Upon startup, that archive may optionally display your splash screen and license agreement. Then it launches a GUI wizard allowing the user to specify installation directories and the like.
Smooth toolchain integration. Excelsior JET has extremely low impact on your established development cycle. You continue using your favorite tools for the most important stages: design, coding, debugging, and testing, without any changes. Once your application works stable on a virtual machine, you compile and package it with JET, conduct quality assurance testing and deploy to enduser systems.
FEATURES



Highly optimizing compiler producing conventional Windows EXE and DLL files
JET Control Panel (graphical front-end)
Support for all J2SE 1.3.0-1.4.1 platform packages (including AWT/Swing), JNI and Invocation API
Limited support for Java dynamic class loading
Interoperability with C/C++/Deplhi via JNI and Invocation API
NEW Interoperability with C++/VB6/VBA via COM
NEW NT Services toolkit
Resource binding
JetPack utility for easy deployment
Royalty-free high performance run-time library
Documentation in JavaHelp and PDF formats
Sample programs
30 days Getting Started Support
(optional) 1 Year of Standard Support
(optional) 1 Year of Maintenance

这是标准版的介绍，个人版功能也差不多，主要是个技术支持的问题。
我已经用它将一个java程序编译成了windows下的.exe文件。看看它的BENEFITS就知道了

[goldencode]

我这几天找了一下，
本地编译器不太多
主要是
jet
jove
IBM HPJ
SuperCede
NativeJ
GCJ
TowerJ
Visual Cafe
FastJ
但坏消息是他们除了GCJ都是收费的，而且GCJ目前虽然可以在Linux上交叉编译
Window的exe但目前不支持AWT和SWING，最贵的是IBM的HPJ 要3千多美刀！他也是性能最好的.
这些工具比较专，所以没找到任何注册骂：（
看来只有IBM的visualAge了，为什么？ 大家自己去想吧。
用visualAge成功的或者找到以上软件注册码的请说一说：D

[goldencode]

是的可以编译成功但一定要有JET的库而且要在它的安装目录下自己乱拷还不行。
这样怎么分发啊。
