jsp中servlet的runtime问题
servlet中能用Runtime吗
问题补充：如果能.
package test;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class Test extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
int i=0;
Runtime r = Runtime.getRuntime();
String str= "start C:\\WINDOWS\\system32\\notepad.exe ";
try
{
while(i!=3)
{
r.exec( "cmd /c "+str);
i++;
}
}
catch(IOException e){}
PrintWriter out=response.getWriter();
i=0;
while(i!=3)
{
out.println( " <html> <body> <h1> This is a servlet test. </h1> </body> </html> ");
i++;
}
out.flush();
}
}
上面的那段代码为什么没有打开记事本???
------解决方案--------------------
@_@,new 出来调用就行了,
