在网上找了该第三方类库,连接到远程linux后默认目录是在/root下,但是现在要执行别的目录下的.sh脚本,直接写该脚本的全路径/opt/ccs/bin/shutdown.sh的话,估计由于该脚本中还包含一些其他的相对路径,无法执行成功。想要先cd到该目录下,然后再./shutdown.sh,但好像该程序每次都会去重新连接linux,所以执行./shutdown.sh时会说找不到该文件。有人能告诉我该怎么处理吗??public class RemoteShellTool {

不知道阁下用commons-net 2.0这个解决该问题,具体是怎么弄的呢,能不能给点代码出来参考下啊,,谢谢啊,
放在login里面,然后再增加一个签退的方法。
这样就能在一个会话里执行多条语句拉~
*看看能不能自己重写。方法已经给你提供了。
*要是可以的话结题吧.哈O(∩_∩)

如果执行多次。流应该怎么处理。如果多次执行那流是不是不要关闭
