  • How to retain XML string as a string field during XML deserialization

    - by detale
    I got an XML input string and want to deserialize it to an object which partially retain the raw XML. <SetProfile> <sessionId>A81D83BC-09A0-4E32-B440-0000033D7AAD</sessionId> <profileDataXml> <ArrayOfProfileItem> <ProfileItem> <Name>Pulse</Name> <Value>80</Value> </ProfileItem> <ProfileItem> <Name>BloodPresure</Name> <Value>120</Value> </ProfileItem> </ArrayOfProfileItem> </profileDataXml> </SetProfile> The class definition: public class SetProfile { public Guid sessionId; public string profileDataXml; } I hope the deserialization syntax looks like string inputXML = "..."; // the above XML XmlSerializer xs = new XmlSerializer(typeof(SetProfile)); using (TextReader reader = new StringReader(inputXML)) { SetProfile obj = (SetProfile)xs.Deserialize(reader); // use obj .... } but XMLSerializer will throw an exception and won't output < profileDataXml 's descendants to "profileDataXml" field in raw XML string. Is there any way to implement the deserialization like that?

  • MVC and repository pattern data effeciency

    - by Shawn Mclean
    My project is structured as follows: DAL public IQueryable<Post> GetPosts() { var posts = from p in context.Post select p; return posts; } Service public IList<Post> GetPosts() { var posts = repository.GetPosts().ToList(); return posts; } //Returns a list of the latest feeds, restricted by the count. public IList<PostFeed> GetPostFeeds(int latestCount) { List<Post> post - GetPosts(); //CODE TO CREATE FEEDS HERE return feeds; } Lets say the GetPostFeeds(5) is supposed to return the 5 latest feeds. By going up the list, doesn't it pull down every single post from the database from GetPosts(), just to extract 5 from it? If each post is say 5kb from the database, and there is 1 million records. Wont that be 5GB of ram being used per call to GetPostFeeds()? Is this the way it happens? Should I go back to my DAL and write queries that return only what I need?

  • Compile error on inheritance of generic inner class extending with bounds

    - by Arne Burmeister
    I have a problem when compiling a generic class with an inner class. The class extends a generic class, the inner class also. Here the interface implemented: public interface IndexIterator<Element> extends Iterator<Element> { ... } The generic super class: public abstract class CompoundCollection<Element, Part extends Collection<Element>> implements Collection<Element> { ... protected class CompoundIterator<Iter extends Iterator<Element>> extends ImmutableIterator<Element> { ... } } The generic subclass with the compiler error: public class CompoundList<Element> extends CompoundCollection<Element, List<Element>> implements List<Element> { ... private class CompoundIndexIterator extends CompoundIterator<IndexIterator<Element>> implements IndexIterator<Element> { ... } } The error is: type parameter diergo.collect.IndexIterator<Element> is not within its bound extends CompoundIterator<IndexIterator<Element>> ^ What is wrong? The code compiles with eclipse, but bot with java 5 compiler (I use ant with java 5 on a mac and eclipse 3.5). No, I cannot convert it to a static inner class.

  • Databinding between 2 Dependency Properties

    - by stefan.at.wpf
    Hello, I'm trying to do databinding between 2 Dependency Properties. I guess this should be quite easy, anyways I just don't get it. I already googled but I couldn't really find out what I'm doing wrong. I'm trying to bind the ControlPointProperty to the QuadraticBezierSegment.Point1Property, however it doesn't work. Thanks for any hint! class DataBindingTest : DependencyObject { // Dependency Property public static readonly DependencyProperty ControlPointProperty; // .NET wrapper public Point ControlPoint { get { return (Point)GetValue(DataBindingTest.ControlPointProperty); } set { SetValue(DataBindingTest.ControlPointProperty, value); } } // Register Dependency Property static DataBindingTest() { DataBindingTest.ControlPointProperty = DependencyProperty.Register("ControlPoint", typeof(Point), typeof(DataBindingTest)); } public DataBindingTest() { QuadraticBezierSegment bezier = new QuadraticBezierSegment(); // Binding Binding myBinding = new Binding(); myBinding.Source = ControlPointProperty; BindingOperations.SetBinding(bezier, QuadraticBezierSegment.Point1Property, myBinding); // Test Binding: Change the binding source ControlPoint = new Point(1, 1); MessageBox.Show(bezier.Point1.ToString()); // gives (0,0), should be (1,1) } }

  • How to test IO code in JUnit?

    - by add
    I'm want to test two services: service which builds file name service which writes some data into file provided by 1st service In first i'm building some complex file structure (just for example {user}/{date}/{time}/{generatedId}.bin) In second i'm writing data to the file passed by first service (1st service calls 2nd service) How can I test both services using mocks without making any real IO interractions? Just for example: 1st service: public class DefaultLogService implements LogService { public void log(SomeComplexData data) { serializer.write(new FileOutputStream(buildComplexFileStructure()), data); or serializer.write(buildComplexFileStructure(), data); or serializer.write(new GenericInputEntity(buildComplexFileStructure()), data); } private ComplextDataSerializer serializer; // mocked in tests } 2nd service: public class DefaultComplexDataSerializer implements ComplexDataSerializer { void write(InputStream stream, SomeComplexData data) {...} or void write(File file, SomeCompexData data) {...} or void write(GenericInputEntity entity, SomeComplexData data) {...} } In first case i need to pass FileOutputStream which will create a file (i.e. i can't test 1st service) In second case i need to pass File. What can i do in 2nd service test if I need to test data which will be written to specified file? (i can't test 2nd service) In third case i think i need some generic IO object which will wrap File. Maybe there is some ready-to-use solution for this purpose?

  • Android customizing ViewFlipper...

    - by wearysamurai
    So I'm having pretty much exactly the problem described here: http://code.google.com/p/android/issues/detail?id=6191 and until the ViewFlipper issue in 2.1 and 2.2 has been resolved, I'm attempting to customize my own ViewFlipper in the manner described: @Override protected void onDetachedFromWindow() { try { super.onDetachedFromWindow(); } catch (IllegalArgumentException e) { // Call stopFlipping() in order to kick off updateRunning() stopFlipping(); } } But I've never done this sort of thing before and am hoping to get a little guidance (as my own efforts are coming up short). Here's what I have so far. FixedFlipper.java: import android.content.Context; import android.util.AttributeSet; import android.widget.ViewFlipper; public class FixedFlipper extends ViewFlipper{ public FixedFlipper(Context context){ super(context); } public FixedFlipper(Context context, AttributeSet attrs){ super(context, attrs); } @Override protected void onDetachedFromWindow(){ try{ super.onDetachedFromWindow(); }catch(Exception e){ super.stopFlipping(); } } } main.xml: <com.site.TestApp.FixedFlipper style="@style/body" android:id="@+id/flipper"> ... </com.site.TestApp.FixedFlipper> And in my activity, I invoke it like so: FixedFlipper flipper = (FixedFlipper)findViewById(R.id.flipper); It seems like it should be pretty straightforward, but I keep getting this: Binary XML file line #4: Error inflating class com.site.TestApp.FixedFlipper I appreciate any suggestions. I've been chasing my tail for hours trying to figure out what piece of the puzzle I'm missing.

  • Why doesn't every class in the .Net framework have a corresponding interface?

    - by Thorsten Lorenz
    Since I started to develop in a test/behavior driven style, I appreciated the ability to mock out every dependency. Since mocking frameworks like Moq work best when told to mock an interface, I now implement an interface for almost every class I create b/c most likely I will have to mock it out in a test eventually. Well, and programming to an interface is good practice, anyways. At times, my classes take dependencies on .Net classes (e.g. FileSystemWatcher, DispatcherTimer). It would be great in that case to have an interface, so I could depend on an IDispatcherTimer instead, to be able to pass it a mock and simulate its behavior to see if my system under test reacts correctly. Unfortunately both of above mentioned classes do not implement such interfaces, so I have to resort to creating adapters, that do nothing else but inherit from the original class and conform to an interface, that I then can use. Here is such an adapter for the DispatcherTimer and the corresponding interface: using System; using System.Windows.Threading; public interface IDispatcherTimer { #region Events event EventHandler Tick; #endregion #region Properties Dispatcher Dispatcher { get; } TimeSpan Interval { get; set; } bool IsEnabled { get; set; } object Tag { get; set; } #endregion #region Public Methods void Start(); void Stop(); #endregion } /// <summary> /// Adapts the DispatcherTimer class to implement the <see cref="IDispatcherTimer"/> interface. /// </summary> public class DispatcherTimerAdapter : DispatcherTimer, IDispatcherTimer { } Although this is not the end of the world, I wonder, why the .Net developers didn't take the minute to make their classes implement these interfaces from the get go. It puzzles me especially since now there is a big push for good practices from inside Microsoft. Does anyone have any (maybe inside) information why this contradiction exists?

  • Correct use of WSDL-generated sources

    - by John K
    How can I easily convert between manually written classes and WSDL-generated equivalents? I have a Java SE 6 thick client that calls a web service to get and store data. The client has a DAO that works with my entity classes, calls <Entity.toDto() to convert them to DTOs, and sends/receives that data with the web service. My issue stems from the fact that the entity classes live on both sides of the service interface: client and server. Each entity has a constructor from the DTO and a toDto function: public class EntityClass { public EntityClass(EntityClassDto dto); public EntityClassDto toDto(); ... } This means I have a handwritten DTO class that the client and server both use. However, the service interface expects the WSDL-generated classes. I have tried writing conversion code between the hand-written DTO and the WSDL-generated DTO and it is tedious and error-prone. What is a reasonable alternative to this? Some back-story: The thick client should be able to have a configurable backend: either direct to the DB or through this web service. The aforementioned DAO is the web service based implementation and another imlpementation that is JPA-based exists.

  • Make JAXWS-based webservice implement interface and unmarshall to known POJOs

    - by John K
    Given a Java SE 6 client, I would like to provide a configurable back-end: either directly to a database or through a web service which connects to a centralized DB. To that end, I've created some JPA- and JAXB-annotated entity classes and a DAO interface in a POJO library like the following: public interface MyDaoInterface { public MyEntity doSomething(); } @javax.persistence.Entity @javax.xml.bind.annotation.XmlRootElement public class MyEntity { private int a; .... } Now, I would like to have my auto-generated web service stubs implement that interface and interact with my defined entity classes, rather than the generated classes provided via the JAX-B unmarshaller. So, the client-side pseudo code would be something like MyDaoInterface dao; if (usingWebservice) dao = new WebserviceDao(); else dao = new JpaDao(); MyEntity e = dao.doSomething(); Is this possible with JPA, JAXB, JAXWS? Is this even advisable? Currently we achieve this through a slow manual process of massaging code, copying generating classes, and doing other things that seem just plain wrong to me.

  • Best way to manipulate and compare strings

    - by vtortola
    I'm developing a REST service, so a request could be something like this: /Data/Main/Table=Customers/ I need to get the segments one by one, and for each segment I will decide wich object I'm going to use, after I'll pass to that object the rest of the query so it can decide what to do next. Basically, the REST query is a path on a tree :P This imply lots String operations (depending on the query complexity), but StringBuilder is useful just for concatenations and remove, you cannot perform a search with IndexOf or similar. I've developed this class that fulfill my requirement, but the problem is that is manipulating Strings, so every time I get one segment ... I'll create extra Strings because String is an inmutable data type: public class RESTQueryParser { String _query; public RESTQueryParser(String query) { _query = query; } public String GetNext() { String result = String.Empty; Int32 startPosition = _query.StartsWith("/", StringComparison.InvariantCultureIgnoreCase) ? 1 : 0; Int32 i = _query.IndexOf("/", startPosition, StringComparison.InvariantCultureIgnoreCase) - 1; if (!String.IsNullOrEmpty(_query)) { if (i < 0) { result = _query.Substring(startPosition, _query.Length - 1); _query = String.Empty; } else { result = _query.Substring(startPosition, i); _query = _query.Remove(0, i + 1); } } return result; } } The server should support a lot of calls, and the queries could be huge, so this is gonna be a very repetitive task. I don't really know how big is the impact on the memory and the performance, I've just readed about it in some books. Should I implement a class that manage a Char[] instead Strings and implement the methods that I want? Or should be ok with this one? Regular expressions maybe?

  • Problem with WPF Data Binding Defined in Code Not Updating UI Elements

    - by Ben
    I need to define new UI Elements as well as data binding in code because they will be implemented after run-time. Here is a simplified version of what I am trying to do. Data Model: public class AddressBook : INotifyPropertyChanged { private int _houseNumber; public int HouseNumber { get { return _houseNumber; } set { _houseNumber = value; NotifyPropertyChanged("HouseNumber"); } } public event PropertyChangedEventHandler PropertyChanged; protected void NotifyPropertyChanged(string sProp) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(sProp)); } } } Binding in Code: AddressBook book = new AddressBook(); book.HouseNumber = 123; TextBlock tb = new TextBlock(); Binding bind = new Binding("HouseNumber"); bind.Source = book; bind.Mode = BindingMode.OneWay; tb.SetBinding(TextBlock.TextProperty, bind); // Text block displays "123" myGrid.Children.Add(tb); book.HouseNumber = 456; // Text block displays "123" but PropertyChanged event fires When the data is first bound, the text block is updated with the correct house number. Then, if I change the house number in code later, the book's PropertyChanged event fires, but the text block is not updated. Can anyone tell me why? Thanks, Ben

  • Map enum in JPA with fixed values ?

    - by Kartoch
    I'm looking for the different ways to map an enum using JPA. I especially want to set the integer value of each enum entry and to save only the integer value. @Entity @Table(name = "AUTHORITY_") public class Authority implements Serializable { public enum Right { READ(100), WRITE(200), EDITOR (300); private int value; Right(int value) { this.value = value; } public int getValue() { return value; } }; @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "AUTHORITY_ID") private Long id; // the enum to map : private Right right; } A simple solution is to use the Enumerated annotation with EnumType.ORDINAL: @Column(name = "RIGHT") @Enumerated(EnumType.ORDINAL) private Right right; But in this case JPA maps the enum index (0,1,2) and not the value I want (100,200,300). Th two solutions I found do not seem simple... First Solution A solution, proposed here, uses @PrePersist and @PostLoad to convert the enum to an other field and mark the enum field as transient: @Basic private int intValueForAnEnum; @PrePersist void populateDBFields() { intValueForAnEnum = right.getValue(); } @PostLoad void populateTransientFields() { right = Right.valueOf(intValueForAnEnum); } Second Solution The second solution proposed here proposed a generic conversion object, but still seems heavy and hibernate-oriented (@Type doesn't seem to exist in JEE): @Type( type = "org.appfuse.tutorial.commons.hibernate.GenericEnumUserType", parameters = { @Parameter( name = "enumClass", value = "Authority$Right"), @Parameter( name = "identifierMethod", value = "toInt"), @Parameter( name = "valueOfMethod", value = "fromInt") } ) Is there any other solutions ? I've several ideas in mind but I don't know if they exist in JPA: use the setter and getter methods of right member of Authority Class when loading and saving the Authority object an equivalent idea would be to tell JPA what are the methods of Right enum to convert enum to int and int to enum Because I'm using Spring, is there any way to tell JPA to use a specific converter (RightEditor) ?

  • Using Google Visualization in GWT 2.0

    - by nick
    I'm working on learning GWT (total newb) and have a question regarding the Visualiztion API provided by Google. This page: http://code.google.com/p/gwt-google-apis/wiki/VisualizationGettingStarted Describes getting started with a pie chart (which is what I need). However I'm trying to do this in a composite UI using UiBinder. To that end I don't know how to handle the callback correctly that is shown: public class SimpleViz implements EntryPoint { public void onModuleLoad() { // Create a callback to be called when the visualization API // has been loaded. Runnable onLoadCallback = new Runnable() { public void run() { Panel panel = RootPanel.get(); // Create a pie chart visualization. PieChart pie = new PieChart(createTable(), createOptions()); pie.addSelectHandler(createSelectHandler(pie)); panel.add(pie); } }; // Load the visualization api, passing the onLoadCallback to be called // when loading is done. VisualizationUtils.loadVisualizationApi(onLoadCallback, PieChart.PACKAGE); } My First assumption is this would go in the UiBinder constructor, correct? Yet this assumes that I want to place the element in the RootLayoutPanel, and I don't. I can't see an elegant and obvious way of placing it in the binder. I submit that even this guess may be wrong. Any ideas from the experts?

  • Class Structure w/ LINQ, Partial Classes, and Abstract Classes

    - by Jason
    I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner. What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class: public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } partial void OnValidate(ChangeAction action) { if (!IsValid) { throw new ApplicationException("Rule violations prevent saving."); } } What I'm wondering is, can you create an abstract class (because "GetRuleViolations" needs to be implemented separately) and extend a partial class? I'm thinking something like this (based on his example): public partial class Dinner : Validation { public IEnumerable<RuleViolation> GetRuleViolations() { yield break; } } This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong). Thanks!

  • Accessing a com object's vtable in c#

    - by Martin Booth
    I'm attempting to access a com object's vtable in memory and getting nowhere. From what I have read, the first 4 bytes in memory of a com object should be a pointer to the vtableptr, which in turn is a pointer to the vtable. Although I'm not sure I expect to find my test method at slot 7 in this com object I have tried them all and nothing looks like the address of my function. If anyone can make the necessary changes to this sample to get it to work (the aim is just to try and invoke the Test method on the Tester class by accessing the com object's vtable and locating the method in whichever row it turns up) I would be very grateful. I know it is rare that anyone would need to do this, but please accept I do need to do something quite similar and have considered the alternatives Thanks in advance [ComVisible(true)] public class Tester { public void Test() { MessageBox.Show("Here"); } } public delegate void TestDelegate(); private void main() { Tester t = new Tester(); GCHandle objectHandle = GCHandle.Alloc(t); IntPtr objectPtr = GCHandle.ToIntPtr(objectHandle); IntPtr vTable = (IntPtr)Marshal.ReadInt32(objectPtr); IntPtr vTablePtr = (IntPtr)Marshal.ReadInt32(vTable); IntPtr functionPtr = (IntPtr)Marshal.ReadInt32(vTablePtr, 7 * 4); // 7 may be incorrect but i have tried many different values TestDelegate func = (TestDelegate)Marshal.GetDelegateForFunctionPointer(functionPtr, typeof(TestDelegate)); func(); objectHandle.Free(); }

  • Amazon EC2 and jbossws

    - by avjaz
    Hi - I've deployed a webservice to a Jboss instance running on Amazon EC2. The webservice works fine locally, but when I deploy on EC2, and go to the /jbossws/services page the Endpoint Address for the webservice is the private DNS of the ec2 instance (domU-X-X-X-X etc...), not the public dns (which I would like it to be). I've tried loading the wsdl by changing the private hostname to the public IP; that works, but when I try to call any of the operations I get a HostNotFoundException, I'm guessing due to the fact that the generated wsdl has the stanza: <service name='XXXService'> <port binding='tns:XXXBinding' name='XXXPort'> <soap:address location='http://domU-XX-XX-XX-XX-XX-XX.compute-1.internal:8080/xx/xx/xx'/> </port> </service> where http://domU-XX-XX-XX-XX-XX-XX.compute-1.internal is the internal dns of the ec2 instance. The wsdl is auto generated - Is there a JAXB annotation I can use so that I can force the generated wsdl to use the public dns of the EC2 instance? Many thanks -

  • Save options selected in AlertDialog spawned from ItemizedOverlay onTap method

    - by ahsteele
    In the description of how to add a list of options to an AlertDialog the official Android documentation alludes to saving a users preferences with one of the "data storage techniques." The examples assume the AlertDialog has been spawned within an Activity class. In my case I've created a class that extends ItemizedOverlay. This class overrides the onTap method and uses an AlertDialog to prompt the user to make a multi-choice selection. I would like to capture and persist the selections for each OverlayItem they tap on. That said I am unsure if utilizing an AlertDialog in this manner is the right approach and open to other suggestions. protected boolean onTap(int index) { OverlayItem item = _overlays.get(index); final CharSequence[] items = { "WiFi", "BlueTooth" }; final boolean[] checked = { false, false }; AlertDialog.Builder builder = new AlertDialog.Builder(_context); builder.setTitle(item.getTitle()); builder.setMultiChoiceItems(items, checked, new DialogInterface.OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int item, boolean isChecked) { // for now just show that the user touched an option Toast.makeText(_context, items[item], Toast.LENGTH_SHORT).show(); } }); builder.setPositiveButton("Okay", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { // should I be examining what was checked here? dialog.dismiss(); } }); builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }); AlertDialog alert = builder.create(); alert.show(); return true; }

  • How to limit speed with BMW JSDK on 116i?

    - by lexicore
    I'm experimenting with the BMW Java SDK on the new BMW 116i Innovation Package. Basic things like turning the lights on and off, starting and stopping the motor work fine. What I'm trying to do now is that to write a carlet which would limit the speed to the maximum configured in the driver profile. Driver identity will be detected as usual via RFID reader. My problem is that though I can read the speed from the tachometer, I can't really limit the speed. Here's what I've got working so far: public class SpeenControllingCarlet extends GenericCarlet { public void start(final VehicleModel model) throws CarletException { RfidReader rfidReader = (RfidReader) model .getDevice(Devices.DRIVER_RFID_READER); Rfid rfid = rfidReader.getRfid(); DriverProfile driverProfile = model.getDriverProfileRegistry() .getDriverProfile(rfid.toString()); if (driverProfile == null) { return; } final Double maxAllowedSpeed = Double.valueOf(driverProfile .getCustomAttribute("maxAllowedSpeed", "190")); Tachometer tachometer = (Tachometer) mode.getDevice(Devices.TACHOMETER); tachometer.addSpeedListener(new SpeedListener() { public void onSpeedChanged(SpeedChangedEvent speedChangedEvent) { if (speedChangedEvent.getCurrentSpeed() > maxAllowedSpeed) { Horn horn = (Horn) mode.getDevice(Devices.HORN); horn.beep(440, 2000); } } }); } } This will just beep for two seconds if the driver goes faster than the driver profile allows. My question is - is there a possibility to actually limit the speed (not just silly beeping)?

  • IncludeExceptionDetailInFaults not behaving as thought

    - by pdiddy
    I have this simple test project just to test the IncludeExceptionDetailInFaults behavior. public class Service1 : IService1 { public string GetData(int value) { throw new InvalidCastException("test"); return string.Format("You entered: {0}", value); } } [ServiceContract] public interface IService1 { [OperationContract] string GetData(int value); } In the app.config of the service i have it set to true <serviceDebug includeExceptionDetailInFaults="True" /> On the client side: try { using (var proxy = new ServiceReference1.Service1Client()) Console.WriteLine(proxy.GetData(5)); } catch (Exception ex) { Console.WriteLine(ex.Message); } This is what I thought the behavior was: Setting to includeExceptionDetailInFaults=true would propagate the exception detail to the client. But I'm always getting the CommunicationObjectFaultException. I did try having the FaultContract(typeof(InvalidCastException)) on the contract but same behavior, only getting the CommunicationObjectFaultException. The only way to make it work was to throw new FaultException(new InvalidCastException("test")); But I thought with IncludeExceptionDetailInFaults=true the above was done automatically. Am I missing something?

  • Implementing Struts 2 Interceptors using Struts 1

    - by Andriy Zakharchuk
    Hello all, I have a legacy application written with Struts 1. The only feature I was asked to add is to protect some actions. Currently any user can do whatever he/she wants. The idea is to allows all user see the data, but block modification operation, i.e. to modify data a user should log in. I know Struts2 has interceptors, so I could attach them to required actions and forward users to log in page when needed. But how can I do similar thing in Struts 1 application? My first idea was to create my own abstract Action class: public class AuthenticatedAction { public ActionForward execute( ActionMapping mapping, ActionForm form, HttpServletRequest theRequest, HttpServletResponse theResponse) { if (!logged) { // forward to log in form } else { doExecute(mapping, form, request, response); } } public abstract ActionForward doExecute( ActionMapping mapping, ActionForm form, HttpServletRequest theRequest, HttpServletResponse theResponse); } Then change all actions that require authentication from extends Action to extends AuthenticatedAction then add login form, login action (which performs authentications and puts this status into the session) and change JSP header tile to display authentication block, e.g., "You are (not logged in)/", Login/Logout. As I guess this should solve the problem. If this doesn't solve the problem, please explain me why. Is there any better (more elegant like interceptors are) way to do this? Thank you in advance.

  • JavaMail: Could not connect to SMTP server.

    - by javacode
    Hi The following code causes an error. Please help me understand what's wrong. import javax.mail.*; import javax.mail.internet.*; import java.util.*; public class SendMail { public static void main(String [] args)throws MessagingException { SendMail sm=new SendMail(); sm.postMail(new String[]{"[email protected]"},"hi","hello","[email protected]"); } public void postMail( String recipients[ ], String subject, String message , String from) throws MessagingException { boolean debug = false; //Set the host smtp address Properties props = new Properties(); props.put("mail.smtp.host", "webmail.emailmyname.com"); // create some properties and get the default Session Session session = Session.getDefaultInstance(props, null); session.setDebug(debug); // create a message Message msg = new MimeMessage(session); // set the from and to address InternetAddress addressFrom = new InternetAddress(from); msg.setFrom(addressFrom); InternetAddress[] addressTo = new InternetAddress[recipients.length]; for (int i = 0; i < recipients.length; i++) { addressTo[i] = new InternetAddress(recipients[i]); } msg.setRecipients(Message.RecipientType.TO, addressTo); // Optional : You can also set your custom headers in the Email if you Want msg.addHeader("MyHeaderName", "myHeaderValue"); // Setting the Subject and Content Type msg.setSubject(subject); msg.setContent(message, "text/plain"); Transport.send(msg); } } Exception: <pre> com.sun.mail.smtp.SMTPSendFailedException: 450 smtpout04.dca.untd.com Authentication required at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1829) at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:1368) at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:886) at javax.mail.Transport.send0(Transport.java:191) at javax.mail.Transport.send(Transport.java:120) at SendMail.postMail(SendMail.java:52) at SendMail.main(SendMail.java:10)

  • There's a black hole in my server (TcpClient, TcpListener)

    - by Matías
    Hi, I'm trying to build a server that will receive files sent by clients over a network. If the client decides to send one file at a time, there's no problem, I get the file as I expected, but if it tries to send more than one I only get the first one. Here's the server code: I'm using one Thread per connected client public void ProcessClients() { while (IsListening) { ClientHandler clientHandler = new ClientHandler(listener.AcceptTcpClient()); Thread thread = new Thread(new ThreadStart(clientHandler.Process)); thread.Start(); } } The following code is part of ClientHandler class public void Process() { while (client.Connected) { using (MemoryStream memStream = new MemoryStream()) { int read; while ((read = client.GetStream().Read(buffer, 0, buffer.Length)) > 0) { memStream.Write(buffer, 0, read); } if (memStream.Length > 0) { Packet receivedPacket = (Packet)Tools.Deserialize(memStream.ToArray()); File.WriteAllBytes(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory), Guid.NewGuid() + receivedPacket.Filename), receivedPacket.Content); } } } } On the first iteration I get the first file sent, but after it I don't get anything. I've tried using a Thread.Sleep(1000) at the end of every iteration without any luck. On the other side I have this code (for clients) . . client.Connect(); foreach (var oneFilename in fileList) client.Upload(oneFilename); client.Disconnect(); . . The method Upload: public void Upload(string filename) { FileInfo fileInfo = new FileInfo(filename); Packet packet = new Packet() { Filename = fileInfo.Name, Content = File.ReadAllBytes(filename) }; byte[] serializedPacket = Tools.Serialize(packet); netStream.Write(serializedPacket, 0, serializedPacket.Length); netStream.Flush(); } netStream (NetworkStream) is opened on Connect method, and closed on Disconnect. Where's the black hole? Can I send multiple objects as I'm trying to do? Thanks for your time.

  • Calculation Expression Parser with Nesting and Variables in ActionScript

    - by yuletide
    Hi There, I'm trying to enable dynamic fields in the configuration file for my mapping app, but I can't figure out how to parse the "equation" passed in by the user, at least not without writing a whole parser from scratch! I'm sure there is some easier way to do this, and so I'm asking for ideas! Basic idea: public var testString:String = "(#TOTPOP_CY#-#HISPOP_CY#)/#TOTPOP_CY#"; public var valueObject:Object = {TOTPOP_CY:1000, HISPOP_CY:100}; public function calcParse(eq:String):String { // do calculations return calculatedValue } So far, I was thinking of splitting the expression by either the operators, or maybe the variable tokens, but that gets rid of the parenthetical nesting. Alternatively, use a series of regex to search and replace each piece of the expression with its value, recursively running until only a number is left. But I don't think regex does math (i.e. replace "\d + \d" with the sum of the two numbers) Ideally, I'd just do a find/replace all variable names with their values, then run an eval(), but there's no eval in AS... eesh I downloaded some course materials for a course on compiler design, so maybe I'll just write a full-fledged calculator language and parser and port it over from the OTHER flex (the parser generator) :-D
