[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - Re: how to call unix shell script from web app?

Code is as below :- import java.io.*; | | /** Demonstrate how to run an external program. **/ | public class MyServlet implements HttpServlet{ | | /** From the main run an servlet . **/ | public doGet( request,response) { | try { | Runtime rt = Runtime.getRuntime (); // step 1 | | Process process = rt.exec ("/call/some/shell"); // step 2 | | InputStreamReader reader = // step 3 | new InputStreamReader ( process.getInputStream () ); | | BufferedReader buf_reader = | new BufferedReader ( reader ); // step 4. | | String line; | while ((line = buf_reader.readLine ()) != null) | System.out.println (line); | | } | catch (IOException e) { | System.out.println (e); | } | } | } // servlet end Make sure you grab the Process & flush the err stream, input tsream & out put stream...Other wise due to insufficient length of err buffers in OS this would hang View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4119242#...
