在java程序中获取当前运行程序的路径
import java.io.*;
public class test {
public static void main(string[] args) {
file directory = new file(".");
try {
file newpath = new file(directory.getcanonicalpath()+"newfolder");
newpath.mkdir();
}catch(exception exp)
{
exp.printstacktrace();
}
}
}
//file directory = new file(".");
//directory.getcanonicalpath();取得当前路径
在jsp页面中调用ping命令—pingip.jsp
