I would have thought this straight forward, but it doesn’t seem the case.

Aim: I am running a shell script ArgCHeck.sh through my .jsp file. This works fine and I can see the output in my system console.

However when I try and output the line into the browser through HTML, its doesn’t seem to work.

I have tried setting the String to Static final String line = "test"; and this works to output the word test, but not the value I want which is from the other String line.

Its probably something I missed, but any help is appreciate.

That’s what you get when you cut and paste. I read the code and it was obvious. Time for a break.

    Here you go.. Just Change the file path .

    <%@page import="java.io.*"%>
<%@page import="java.util.*"%>
<%!
private String runScriptFile(){
    String strRetVal = "";
    Runtime r=Runtime.getRuntime();
    Process p=null;
    String s=null;
    String cmd="D:\\test.bat";
    try{
        p=r.exec(cmd);
        InputStreamReader isr=new InputStreamReader(p.getInputStream());
        BufferedReader br=new BufferedReader(isr);
        String line = null;
        while((line = br.readLine()) != null){
            strRetVal += line + "<br>";
            System.out.println(line);
        }
        p.waitFor();
    }catch(Exception e){
        e.printStackTrace();
    }
    return strRetVal;
}
