Hi,

The code for handling the forward message is as follows:


public void handle(Callback callbacks[]) throws IOException, UnsupportedCallbackException { try { //String path = "/DatabaseLoginModule.jsp"; NameCallback fc = (NameCallback)callbacks[0]; Properties props = new Properties(); props.load(new FileInputStream("AFWConf.properties")); timeout = Integer.parseInt(props.get("Timeout").toString()); System.out.println("time out captured is :"+timeout); System.out.println(fc.getPrompt()); System.out.print("\t\t\tForwarding to...." + fc.getPrompt() + "....."); try { System.out.println("Entered the block for requestdispatcher"); req.getRequestDispatcher(fc.getPrompt()).forward(req, res); } catch(Exception e) { System.out.println("Exception in forwarding"); System.out.println("Root Cause :" + e.getMessage()); throw new Exception("Cannot Forward the Request"); } System.out.println("Forwarded"); System.out.print("Sleeping ...."); dataArrived = false; await(); System.out.print("wait is completed......."); if(dataArrived) { System.out.println("Data Arrived"); } else { System.out.println("Request Timedout"); throw new Exception("Request Timedout"); } } catch(Exception e) { throw new IOException("Request Timedout"); } for(int i = 1; i < callbacks.length; i++) { if(callbacks[i] instanceof TextInputCallback) { TextInputCallback tc = (TextInputCallback)callbacks[i]; if(tc.getPrompt().equals("FingerPrint")) { System.out.println("Call back handler setting the finger print"); tc.setText(fingerPrint); fingerPrint = ""; } else if(tc.getPrompt().equalsIgnoreCase("MatchStatus")) { System.out.println("setting match status"); tc.setText(matchStatus); matchStatus = ""; } else { tc.setText(signedData); System.out.println("Call back handler setting the signed data"); signedData = ""; } } else if(callbacks[i] instanceof NameCallback) { NameCallback nc = (NameCallback)callbacks[i]; nc.setName(username); username = ""; } else if(callbacks[i] instanceof PasswordCallback) { PasswordCallback pc = (PasswordCallback)callbacks[i]; pc.setPassword(password.toCharArray()); password = ""; } else { throw new UnsupportedCallbackException(callbacks[i], "Unrecognized Callback"); } } } synchronized void await() { if(!dataArrived) { try { wait(timeout); } catch(InterruptedException e) { e.printStackTrace(); } } } public synchronized void callNotify() { notify(); } public void setUsername(String newValue) { username = newValue; } public void setpassword(String newValue) { password = newValue; } public void setRequest(HttpServletRequest newValue) { req = newValue; } public void setResponse(HttpServletResponse newValue) { res = newValue; } public void setDataArrived(boolean newValue) { dataArrived = newValue; callNotify(); } public void setSignedData(String signedData) { this.signedData = signedData; } public void setFingerPrint(String fingerPrint) { System.out.println("SETTING FINGERPRINT VALUE" + fingerPrint.length()); this.fingerPrint = fingerPrint; } public void setMatchStatus(String matchStatus) { System.out.println("setting match status in AuthcallbackHandler"); this.matchStatus = matchStatus; } }

Hi Ben,

Thanks for your reply.

There no error logged in the log file. It is waiting for the server response until the time out period with out any errors and once the session gets timed out the page is displayed

Another option is that if I use an include instead of forward and using flushBuffer to commit the work its working fine.

Can you guide me with the possibilities of the errors.

Thanks

Hi,

I think i have a problem with requestdispatcher and forward method as we are migrating our project from tomcat 4.1 to tomcat 5.5.

The code written works fine with tomcat 4.1 but with tomcat 5.5 after the we are calling the getRequestDispatcher(path).forward(req,res) method the requested jsp should be displayed on the browser, which is not happening.

Can you guide me in this regard as I couldn't pinpoint the exact error location.
