hi
Iam facing a problem on executing a linux shell script from JSP using Tomcat server.Iam successfully able to execute to script using the following java code
import java.io.*;
class shExecute{
public static void main(String args[]){
Runtime r=Runtime.getRuntime();
Process p =null;
String cmd="/home/shdir/runmms.sh";
try{
p=r.exec(cmd);
InputStreamReader isr=new Input StreamReader(p.getInputStream());
String line=null;
while((line=br.readLine())!=null){
System.out.println(line);
}
p.waitFor();
}
catch(Exception e){System.out.println(e);}
System.out.println(p.exitValue());
}
}
If i try to run the same script using the following jsp code iam not able to run the script.The following is the JSP code
<%@page import="java.io.*"%>
<%
Runtime r=Runtime.getRuntime();
Process p=null;
String s=null;
String cmd="/home/shdir/runmms.sh";
try{
p=r.exec(cmd);
InputStreamReader isr=new InputStreamReader(p.getInputStream());
BufferedReader br=new BufferedReader(isr);
String line=null;
while((line = br.readLine()) != null){
System.out.println(line);
}
p.waitFor();
}
catchException e){
out.println(e);
}
System.out.println(p.exitValue());
%>
can anybody give me the solution why the same java code is not working using JSP.Can there be any problem with Tomact?
Thanks to all in advance

replace System.out.println with just out.println and it will work ;-)
