1. jvm.dll要在环境变量PATH，例如 ...;D:\java\sdk6\jre\bin\client

 2. 需要的jar要合并为一个

 

B=byte    C=char    D=double    F=float    I=int    J=long    S=short    V=void    Z=boolean    Lfully-qualified-class=fully qualified class    [type=array of type>    (argument types)return type=method type. If no arguments, use empty argument types: (). If return type is void (or constructor) use (argument types)V.
