java 控制台程序打包后无法运行 Could not find the main class: cmdjava.jar. Program will exit.
是用myeclipse导出的,导出时已经指定了 main class
MANIFEST.MF文件中
Main-Class:指定了 程序的 主函数位置
运行时报错具体如下:
f:\test>java cmdjava.jar
Exception in thread "main" java.lang.NoClassDefFoundError: cmdjava/jar
Caused by: java.lang.ClassNotFoundException: cmdjava.jar
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

你的manifest里面到底是咋写的呢
呵呵 你的java命令后面
这样滴
java -jar cmdjava.jar
C:\Documents and Settings\Administrator>java
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
追问
MANIFEST.MF
Manifest-Version: 1.0
Main-Class: com.ora.test
你是说我命令写错了吗
追答
java -jar cmdjava.jar
追问
还是不行啊 按照那个写的啊
我估计是 lib 下面用引用的jar包 没有导进去
可是又不记得怎么引用到项目里了
追答
使用manifest.mf清单文件把lib下面的类加进去
Manifest-Version: 1.0
Class-Path: . \lib\a.jar \lib\b.jar \lib\c.jar
Main-Class: test.class
jar -cvfm cmdjava.jar manifest.mf -C c:\test\ .
何来以后
