java如何打包

建议使用ANT打包工具，下载地址:

此工具用java编写，跨平台，能实现很多功能：编译、打包、运行、文件操作、数据库操作、自定义任务等。

主要使用方法：在工程目录下编写build.xml配置文件，然后运行ant即可：

#ant

或

#java -jar ant.jar

下面给你提供一个例子，是jakarta-oro-2.0.8的包的build.xml

?xml version="1.0"?

build.xml文件的编写可参见ant发行版中的使用文档

你也可以自己编写脚本打包，使用jdk发行版中的jar命令，例如：

#jar cmf myManifestFile myFile.jar *.class

注意还需要自己编写MANIFEST.MF文件配置包属性。具体可以参见javadoc

当然还可以使用集成开发环境提供的打包工具，如JBuilder提供打包工具，但这样程序的移植性不强，建议不要使用，就使用ant比较好。
