static BThread threadB;
public static void main(String[] args) {
// TODO 自动生成方法存根

}
}
}运行后控制台提示:
属性未被指定且 ExecPermissions/ExecOptionPermissions
均未被授权。随后的激活尝试失败,原因是对
ExecPermission/ExecOptionPermission 的权限检查失败。 有关如何

http://java.sun.com/j2se/1.4/docs/tooldocs/win32/rmid.html但纳闷的是,再dos环境下编译、运行都正常。新手上路,请多多指教。谢谢!!

http://java.sun.com/j2se/1.4/docs/tooldocs/win32/rmid.html 不过第二次再运行,可以了。真不知道咋回事,这是否与eclipse的版本或设置有关系呢。
