  • Validation with State Pattern for Multi-Page Forms in ASP.NET

    - by philrabin
    I'm trying to implement the state pattern for a multi-page registration form. The data on each page will be accumulated and stored in a session object. Should validation (including service layer calls to the DB) occur on the page level or inside each state class? In other words, should the concrete implementation of IState be concerned with the validation or should it be given a fully populated and valid object? See "EmptyFormState" class below: namespace Example { public class Registrar { private readonly IState formEmptyState; private readonly IState baseInformationComplete; public RegistrarSessionData RegistrarSessionData { get; set;} public Registrar() { RegistrarSessionData = new RegistrarSessionData(); formEmptyState = new EmptyFormState(this); baseInformationComplete = new BasicInfoCompleteState(this); State = formEmptyState; } public IState State { get; set; } public void SubmitData(RegistrarSessionData data) { State.SubmitData(data); } public void ProceedToNextStep() { State.ProceedToNextStep(); } } //actual data stored in the session //to be populated by page public class RegistrarSessionData { public string FirstName { get; set; } public string LastName { get; set; } //will include values of all 4 forms } //State Interface public interface IState { void SubmitData(RegistrarSessionData data); void ProceedToNextStep(); } //Concrete implementation of IState //Beginning state - no data public class EmptyFormState : IState { private readonly Registrar registrar; public EmptyFormState(Registrar registrar) { this.registrar = registrar; } public void SubmitData(RegistrarSessionData data) { //Should Validation occur here? //Should each state object contain a validation class? (IValidator ?) //Should this throw an exception? } public void ProceedToNextStep() { registrar.State = new BasicInfoCompleteState(registrar); } } //Next step, will have 4 in total public class BasicInfoCompleteState : IState { private readonly Registrar registrar; public BasicInfoCompleteState(Registrar registrar) { this.registrar = registrar; } public void SubmitData(RegistrarSessionData data) { //etc } public void ProceedToNextStep() { //etc } } }

  • HTTP 500 a problem on CAS Server while setting SSLVerifyClent as "required"

    - by Huiyu.Bird
    I have 3 server, a Apache Server, a JBOSS Server and a CAS Server for SSO. The Apache Server resolve all request with a domain such as www.request.com, and the path of CAS Server is www.request.com/cas, and JBOSS Server is www.request.com/jboss (This app got a CAS client). My problem is if I set SSLVerifyClient require for the NameVirtualHost of www.request.com in my Apache Server, I got a HTTP 500 error during the redirecting to the JBOSS Server(http://www.request.com/jboss), after logined in the CAS login page successfully. But everything goes successfully if there is no SSLVerifyClient require . Error logs of my Apache Server : [Mon Apr 19 17:07:25 2010] [error] Re-negotiation handshake failed: Not accepted by client!? Error logs of my JBOSS Server : 2010-04-19 17:29:57,263 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/jboss].[jsp]] (ajp-0.0.0.0-8009-1) Servlet.service() for servlet jsp threw exception org.jasig.cas.client.validation.TicketValidationException: The CAS server returned no response. at org.jasig.cas.client.validation.AbstractUrlBasedTicketValidator.validate(AbstractUrlBasedTicketValidator.java:162) at org.jasig.cas.client.validation.AbstractTicketValidationFilter.doFilter(AbstractTicketValidationFilter.java:129) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jasig.cas.client.authentication.AuthenticationFilter.doFilter(AuthenticationFilter.java:103) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jasig.cas.client.session.SingleSignOutFilter.doFilter(SingleSignOutFilter.java:78) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:96) at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:75) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.in Any tips will be highly appreciated.

  • Debugging PHP Mail() and/or PHPMailer

    - by Agos
    Hi, I'm quite stuck with a problem sending mail from a PHP script. Some data: Shared hosting, no SSH access, only hosting provider panel PHP version 5.2.5 Last year I built a site which had no problems sending mail with the same hosting Let's say the domain is “domain.com” and my private address is “[email protected]” for anonimity's sake in the following code. Here's the code: <?php error_reporting(E_ALL); ini_set("display_errors", 1); $to = "[email protected]"; $subject = "Hi"; $body = "Test 1\nTest 2\nTest 3"; $headers = 'From: [email protected]' . "\r\n" . 'errors-to: [email protected]' . "\r\n" . 'X-Mailer: PHP/' . phpversion(); if (mail($to, $subject, $body, $headers)) { echo("Message successfully sent"); } else { echo("Message sending failed"); } require('class.phpmailer.php'); $message = "Hello world"; $mail = new PHPMailer(); $mail->CharSet = "UTF-8"; $mail->AddAddress("[email protected]", "Agos"); $mail->SetFrom("[email protected]","My Site"); $mail->Subject = "Test Message"; $mail->Body = $message; $mail->Send(); ?> And here is what I get: Message sending failed 'ai' = 'application/postscript', 'eps' = 'application/postscript', 'ps' = 'application/postscript', 'smi' = 'application/smil', 'smil' = 'application/smil', 'mif' = 'application/vnd.mif', 'xls' = 'application/vnd.ms-excel', 'ppt' = 'application/vnd.ms-powerpoint', 'wbxml' = 'application/vnd.wap.wbxml', 'wmlc' = 'application/vnd.wap.wmlc', 'dcr' = 'application/x-director', 'dir' = 'application/x-director', 'dxr' = 'application/x-director', 'dvi' = 'application/x-dvi', 'gtar' = 'application/x-gtar', 'php' = 'application/x-httpd-php', 'php4' = 'application/x-httpd-php', 'php3' = 'application/x-httpd-php', 'phtml' = 'application/x-httpd-php', 'phps' = 'application/x-httpd-php-source', 'js' = 'application/x-javascript', 'swf' = 'application/x-shockwave-flash', 'sit' = 'application/x-stuffit', 'tar' = 'application/x-tar', 'tgz' = 'application/x-tar', 'xhtml' = 'application/xhtml+xml', 'xht' = 'application/xhtml+xml', 'zip' = 'application/zip', 'mid' = 'audio/midi', 'midi' = 'audio/midi', 'mpga' = 'audio/mpeg', 'mp2' = 'audio/mpeg', 'mp3' = 'audio/mpeg', 'aif' = 'audio/x-aiff', 'aiff' = 'audio/x-aiff', 'aifc' = 'audio/x-aiff', 'ram' = 'audio/x-pn-realaudio', 'rm' = 'audio/x-pn-realaudio', 'rpm' = 'audio/x-pn-realaudio-plugin', 'ra' = 'audio/x-realaudio', 'rv' = 'video/vnd.rn-realvideo', 'wav' = 'audio/x-wav', 'bmp' = 'image/bmp', 'gif' = 'image/gif', 'jpeg' = 'image/jpeg', 'jpg' = 'image/jpeg', 'jpe' = 'image/jpeg', 'png' = 'image/png', 'tiff' = 'image/tiff', 'tif' = 'image/tiff', 'css' = 'text/css', 'html' = 'text/html', 'htm' = 'text/html', 'shtml' = 'text/html', 'txt' = 'text/plain', 'text' = 'text/plain', 'log' = 'text/plain', 'rtx' = 'text/richtext', 'rtf' = 'text/rtf', 'xml' = 'text/xml', 'xsl' = 'text/xml', 'mpeg' = 'video/mpeg', 'mpg' = 'video/mpeg', 'mpe' = 'video/mpeg', 'qt' = 'video/quicktime', 'mov' = 'video/quicktime', 'avi' = 'video/x-msvideo', 'movie' = 'video/x-sgi-movie', 'doc' = 'application/msword', 'word' = 'application/msword', 'xl' = 'application/excel', 'eml' = 'message/rfc822' ); return (!isset($mimes[strtolower($ext)])) ?

  • Iphone: TabView + TableView

    - by OneTrickPonySoft
    I think I'm missing something simple, but I can't figure out exactly what it is. I'm trying to set up an App with a UITabViewController, and one of the Tabs will have a UITableView and UISearchBar (but no Navigation Controller). I set up the UITabViewController with all the tabs in interface builder, and the views are in their own xib files. The xib file for the tab with the UITableView is set up and connected as follows. Stuff in the browser: File's owner (Class is my custom class that is a child of UITableViewController) view - View View (class UIView, reference view - File's owner) contains: UITableView (if i try and set references to the data source / delegate, the app breaks) UISearchBar (unconfigured at the moment) This setup displays all the items and doesn't lock up, but I can't assign a DataSource without it crashing when i try and load the tab with the UITableView. What should I do to get data into this table, either in IB or code? My ideas are as follows: Implement custom UITableView class, hook up to table view in IB or to custom tableviewcontroller in Xcode. Pound head or laptop against the wall until it works. Update: Here's the error the simulator pushes to the console when I connect the Tableview's data source and delegate to File Owner (who's class is my custom tableviewcontroller). 2/14/09 6:59:12 PM TabBarWillbeRight[33172] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[UIViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x523760'

  • Java Performance measurement

    - by portoalet
    Hi, I am doing some Java performance comparison between my classes, and wondering if there is some sort of Java Performance Framework to make writing performance measurement code easier? I.e, what I am doing now is trying to measure what effect does it have having a method as "synchronized" as in PseudoRandomUsingSynch.nextInt() compared to using an AtomicInteger as my "synchronizer". So I am trying to measure how long it takes to generate random integers using 3 threads accessing a synchronized method looping for say 10000 times. I am sure there is a much better way doing this. Can you please enlighten me? :) public static void main( String [] args ) throws InterruptedException, ExecutionException { PseudoRandomUsingSynch rand1 = new PseudoRandomUsingSynch((int)System.currentTimeMillis()); int n = 3; ExecutorService execService = Executors.newFixedThreadPool(n); long timeBefore = System.currentTimeMillis(); for(int idx=0; idx<100000; ++idx) { Future<Integer> future = execService.submit(rand1); Future<Integer> future1 = execService.submit(rand1); Future<Integer> future2 = execService.submit(rand1); int random1 = future.get(); int random2 = future1.get(); int random3 = future2.get(); } long timeAfter = System.currentTimeMillis(); long elapsed = timeAfter - timeBefore; out.println("elapsed:" + elapsed); } the class public class PseudoRandomUsingSynch implements Callable<Integer> { private int seed; public PseudoRandomUsingSynch(int s) { seed = s; } public synchronized int nextInt(int n) { byte [] s = DonsUtil.intToByteArray(seed); SecureRandom secureRandom = new SecureRandom(s); return ( secureRandom.nextInt() % n ); } @Override public Integer call() throws Exception { return nextInt((int)System.currentTimeMillis()); } } Regards

  • Problems with GData Request Token

    - by Dan Delgado
    We have successfully used GData libraries to access a user's Google Docs. But we encountered problems when many users log in to our site and authorize our web app at the same time or successively. Here's what happens: First user successful logs in, authorizes our web app via OAuth and is able to add rubric (or google spreadsheet). Second user, immediately after first user adds a rubric, successfully logs in then webapp fails on authorize (Token not given. I tried to log it.) Third user fails on login. Fourth user was able to log in, authorize via OAuth, and create rubrics successfully. Fifth user was able to log in but like the second user, gets an invalid token on authorize (Token not given.) And the list goes on. Results were unpredicatable. Below is an excerpt of the stack trace we get when the fail scenario happens: Nested in org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.NullPointerException: java.lang.NullPointerException at com.google.gdata.client.authn.oauth.OAuthUtil.normalizeParameters(OAuthUtil.java:158) at com.google.gdata.client.authn.oauth.OAuthUtil.getSignatureBaseString(OAuthUtil.java:81) at com.google.gdata.client.authn.oauth.OAuthHelper.addCommonRequestParameters(OAuthHelper.java:649) at com.google.gdata.client.authn.oauth.OAuthHelper.getOAuthUrl(OAuthHelper.java:592) at com.google.gdata.client.authn.oauth.OAuthHelper.getUnauthorizedRequestToken(OAuthHelper.java:276) at com.projectrix.controller.OAuthController.authorize(OAuthController.java:59) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Method.java:40) Help!

  • Two PickerViews in save View issue?

    - by NextRev
    I'm trying to have 2 pickerviews in the same view. It works except for two things. If one pickerview has more rows than the other the app crashes when picking an item from the pickerview with more items. Also I created an NSLog for the pickerviews and the console shows that I'm picking two items at once when in fact i'm only dealing with one pickerview.

  • How to print "Hello, world!" (in every possible way)

    - by Attila Oláh
    Here's what I', trying to do: 1 language: (Python < 3): print "Hello, world!" 2 languages: (Python < 3 & Windows Shell, aka .bat file): rem=""" echo "Hello, world!" exit """ print "Hello, world!" Next step could be something like bash. Since the above one raises an exception, I tried to make it not raise exceptions, like this: rem=""" echo "Hello, world!" exit """ exit="" exit print "Hello, world!" The only issue is, of course, it won't print the hello world. And I really want it to print that hello world for me. Anyone can help with this? Also, any other language would do it, just don't break the previous ones (i.e. the answer still has to be valid Python code and print out the nice hello world greeting when run with Python.) Any ideas are welcome. I'm making this a community wiki so feel free to add ideas to the list.

  • c# CF Restart a thread

    - by Ed
    Hi all, Supose you have a form with a button that starts/stops a thread (NOT pausing or interrupting, I really need to stop the thread !) Check out this code: Constructor() { m_TestThread = new Thread(new ThreadStart(ButtonsThread)); m_bStopThread = false; } ButtonClick { // If the thread is not running, start it m_TestThread.Start(); // If the thread is running, stop it m_bStopThread = true; m_TestThread.Join(); } ThreadFunction() { while(!m_bStopThread) { // Do work } } 2 questions (remember CF): - How can I know if the thread is running (I cannot seem to access the m_pThreadState, and I've tried the C++ GetThreadExitCode(), it give false results) ? - Most important question : if I have stopped the thread, I cannot restart it, most probably because the m_TestThread.m_fStarted is still set (and it is private so I cannot access it) ! And thus m_TestThread.Start() generates an exception (StateException). Stopping the thread with an Abort() doesn't solve it. If I put my m_TestThread = null; it works, but then I create a memory leak. The GC doesn't clean up either, even if I wait for xx seconds. Anybody has an idea ? All help highly appreciated ! Grtz E

  • How do I find out what process Id and thread id / name has a file open

    - by peter
    Hi All, I am using C# in an application and am having some problems with a file becoming locked. The piece of code does this, while (true) { Read a packet from a socket (with data in it to add to the file) Open a file Writes data to it Close a file } But in the process the file becomes locked. I don't really understand how, we are are definately catching and reporting exceptions so I don't see how the file doesn't get closed every time. My best guess is that something else is opening the file, but I want to prove it. Can someone please provide a piece of code to check whether the file is open and if so report what processid and threadid has the file open. For example if I had this code, StreamWriter streamWriter1 = new StreamWriter(@"c:\logs\test.txt"); streamWriter1.WriteLine("Test"); // code to check for locks?? StreamWriter streamWriter2 = new StreamWriter(@"c:\logs\test.txt"); streamWriter1.Close(); streamWriter2.Close(); That will throw an exception because the file is locked when we try and open it the second time. So where the comment is what could I put in there to report that the current app (process Id) and the current thread (thread Id) have the file locked? Thanks.

  • Get Chinese Romanization from Google Translate API

    - by krubo
    The Google language translate API works cleanly to translate into Chinese: <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script> google.load('language','1'); function googletrans(text) { google.language.translate(text,'en','zh',function(result) { alert(result.translation); }); } </script> <input onchange="googletrans(this.value);"> Example input: "Hello" Result: "??" My problem is I can't get the Romanization (pronunciation using English letters). This is a known issue. Now the data is right there on translate.google.com (Example input: "Hello" Result: "Ni hao") and I can even see it by pointing my browser to: http://translate.google.com/translate_a/t?client=t&text=hello&hl=en&sl=en&tl=zh-CN&otf=2&pc=0 Result: {"sentences":[{"trans":"??","orig":"hello","translit":"Ni hao"}], "dict":[{"pos":"interjection","terms":["?"]}],"src":"en"} But somehow when I try to get this URL with ajax it fails (XMLHttpRequest Exception 101). Is there any way to retrieve this Romanization data with ajax?

  • Castle Windsor, Fluent Nhibernate, and Automapping Isession closed problem

    - by SImon
    I'm new to the whole castle Windsor, Nhibernate, Fluent and Automapping stack so excuse my ignorance here. I didn't want to post another question on this as it seems there are already a huge number of questions that try to get a solution the Windsor nhib Isession management problem, but none of them have solved my problem so far. I am still getting a ISession is closed exception when I'm trying to call to the Db from my Repositories,Here is my container setup code. container.AddFacility<FactorySupportFacility>() .Register( Component.For<ISessionFactory>() .LifeStyle.Singleton .UsingFactoryMethod(() => Fluently.Configure() .Database( MsSqlConfiguration.MsSql2005. ConnectionString( c => c.Database("DbSchema").Server("Server").Username("UserName").Password("password"))) .Mappings ( m => m.AutoMappings.Add ( AutoMap.AssemblyOf<Message>(cfg) .Override<Client>(map => { map.HasManyToMany(x => x.SICCodes).Table("SICRefDataToClient"); }) .IgnoreBase<BaseEntity>() .Conventions.Add(DefaultCascade.SaveUpdate()) .Conventions.Add(new StringColumnLengthConvention(),new EnumConvention()) .Conventions.Add(new EnumConvention()) .Conventions.Add(DefaultLazy.Never()) ) ) .ExposeConfiguration(ConfigureValidator) .ExposeConfiguration(BuildDatabase) .BuildSessionFactory() as SessionFactoryImpl), Component.For<ISession>().LifeStyle.PerWebRequest.UsingFactoryMethod(kernel => kernel.Resolve<ISessionFactory>().OpenSession() )); In my repositories i inject private readonly ISession session; and use it as followes public User GetUser(int id) { User u; u = session.Get<User>(id); if (u != null && u.Id > 0) { NHibernateUtil.Initialize(u.UserDocuments); } return u; in my web.config inside <httpModules>. i have also added this line <add name="PerRequestLifestyle" type="Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleModule, Castle.Windsor"/> I'm i still missing part of the puzzle here, i can't believe that this is such a complex thing to configure for a basic need of any web application development with nHibernate and castle Windsor. I have been trying to follow the code here windsor-nhibernate-isession-mvc and i posted my question there as they seemed to have the exact same issue but mine is not resolved.

  • Making ANTLR generated class files into one jar file.

    - by prosseek
    With ANTLR, I get some java class files after compilation. And I need to make all the class files into one jar file. I make manifest.mf file that has one line "Main-class: Test" to indicate the main file. I run 'jar cmf manifest.mf hello.jar *.class' to get hello.jar file. But when I try to run 'java -jar hello.jar', I get the following error messages. $ java -jar hello.jar Exception in thread "main" java.lang.NoClassDefFoundError: Test Caused by: java.lang.ClassNotFoundException: Test at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:315) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:250) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) What's wrong? I get correct result when I run 'java Test'. The example that I used is the source code from the book 'The Definitive ANTLR Reference' that you can download from http://www.pragprog.com/titles/tpantlr/source_code The example is in /tour/trees/. I get a bunch of class files after compiling g and java files.

  • send arrow keys using ganymed ssh java

    - by José Ramón Pérez Rubio
    I am using Ganymed ssh to connect to a remote machine and apart from sending commands I need to send the arrows keys (left and right keys). I can send commands but when I send the arrows keys nothing happends. This is what I have: public boolean createShell() throws Exception { try { // ... m_session= connection.openSession(); m_commandWriter = new OutputStreamWriter(m_session.getStdin()); String encoding=m_commandWriter.getEncoding(); //encoding is UFT8 m_errorPipe=new SSHSyncPipe(m_session.getStderr()); m_outputPipe=new SSHSyncPipe(m_session.getStdout()); m_outputPipe.start(); m_errorPipe.start(); // m_session.requestPTY("bash"); m_session.requestDumbPTY(); m_session.startShell(); m_shellCreated=true; return true; } } So if I use m_commandWriter.write(ls"\r\n"); m_commandWriter.flush(); It works, but m_commandWriter.write(37);//37 is the code for left arrow m_commandWriter.flush(); Doesn't work. Does anyone know what I am doing wrong? Thank you

  • ASP.Net HttpModule List<> content

    - by test
    We have created an http module that loads data on initialize into a list, and uses that list on every endrequest event of application. However we got a null reference exception on the module at endRequest event complaining that the content is null. Yet we are sure that at module initialization we have put non-null objects correctly. How is this possible? Any ideas? Thanks in advance. The place where i fill the data into the list what named as "Pages" : using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { LandingPageDetails details = new LandingPageDetails(); details.DomainId = Convert.ToInt32(reader["DomainId"]); details.PageId = Convert.ToInt32(reader["TrackingPageId"]); details.PageAddress = Convert.ToString(reader["PageAddress"]); if (!string.IsNullOrEmpty(details.PageAddress)) { Pages.Add(details); } } } // Find the related record on EndRequesst event LandingPageDetails result = Pages.Find ( delegate(LandingPageDetails current) { return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); } ); The line what we get the error return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); "current" is the null object P.S : It works properly, but one day later contents become null. Possibly, there is something wrong on IIS. Our server is Windows 2003, IIS 6.0
