call lynx from jsp script
- by Piero
Hi,
I have an execute(String cmd) in a jsp script that calls the exec method from the Runtime class.
It works when I call a local command, like a php script stored on the server. for example: /usr/bin/php /path/to/php/script arg1 arg2
So I guess my execute command is ok, since it is working with that.
Now when I try to call lynx, the text-based web browser, it does not work.
If I call it in a terminal, it works fine:
/usr/bin/lynx -dump -accept_all_cookies 'http://www.someurl.net/?arg1=1&arg2=2'
But when I call this from my execute command, nothing happens...
Any idea why?
This is my execute method:
public String execute(String cmd){
Runtime r = Runtime.getRuntime();
Process p = null;
String res = "";
try {
p = r.exec(cmd);
InputStreamReader isr = new InputStreamReader(p.getInputStream());
BufferedReader br = new BufferedReader(isr);
String line = null;
//out.println(res);
while ((line = br.readLine()) != null) {
res += line;
}
p.waitFor();
} catch (Exception e) {
res += e;
}
System.out.println(p.exitValue());
return res;
}
