  • Hibernate Mapping Annotation Question?

    - by paddydub
    I've just started using hibernate and I'm trying to map walking distance between two coordinates into a hashmap, There can be many connections from one "FromCoordinate" to another "ToCoordinate". I'm not sure if i've implemented this correctly, What annotations do i need to map this MashMap? Thanks @Entity @Table(name = "COORDCONNECTIONS") public class CoordinateConnection implements Serializable{ private static final long serialVersionUID = -1624745319005591573L; /** auto increasing id number */ @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "ID") @id private int id; @Embedded public FromCoordinate fromCoord; @Embedded public ToCoordinate toCoord; HashMap<Coordinate, ArrayList<Coordinate>> coordWalkingConnections = new HashMap<Coordinate, ArrayList<Coordinate>>(); } public class FromCoordinate implements ICoordinate { @Column(name = "FROM_LAT") private double latitude; @Column(name = "FROM_LNG") private double longitude; } public class ToCoordinate implements ICoordinate { @Column(name = "TO_LAT") private double latitude; @Column(name = "TO_LNG") private double longitude; @Column(name = "DISTANCE") private double distance; } DATABASE STRUCTURE id FROM_LAT FROM_LNG TO_LAT TO_LNG Dist 1 43.352669 -6.264341 43.350012 -6.260653 0.38 2 43.352669 -6.264341 43.352669 -6.264341 0.00 3 46.352669 -6.264341 43.353373 -6.262013 0.17 4 47.352465 -6.265865 43.351290 -6.261200 0.25 5 45.452578 -6.265768 43.352788 -6.264396 0.01 6 45.452578 -6.265768 45.782788 -6.234523 0.01 ..... ... .

  • Flexible design - customizable entity model, UI and workflow

    - by Ngm
    Hi All, I want to achieve the following aspects in the software I am building: 1. Customizable entity model 2. Customizable UI 3. Customizable workflow I have thought about an approach to achieve this, I want you to review this and make suggestions: Entity objects should be plain objects and will hold just data Separate Entity model and DB Schema by using an framework (like NHibernate?). This will allow easy modification of entity objects. Business logic to fetch/modify entities has to be granular enough so that they can be invoked as part of the workflow. Business objects should not hold any state, and hence will contain only static methods The workflow will decide depending upon the "state" of an entity/entities which methods on business object/objects to invoke. The workflow should obtain the results of the processing and then pass on the business objects to the appropriate UI screen. The UI screen has to contain instructions about how to display a given entity/entites. Possibly the UI has to be generated dynamically based on a set of UI instructions. (like XUL) What do you think about this approach? Suggest which existing frameworks (like NHiberante, Window Workflow) fit into this model, so that I will not spend time on coding these frameworks Also suggest is there any asp.net framework that can generate dynamic asp.net ajax pages based on a set of UI instructions (like Mozilla XUL)? I have recently been exploring Apache Ofbiz and was impressed by its ability to customize most areas of the application: UI, workflow, entities. Is there any similar (not necessarily an ERP system) application developed in C#/.Net which offers a similar level of customization? I am looking for examples of applications developed in C# that are highly customizable in terms of UI, Workflow and Entity Model

  • WCF contracts - namespaces and SerializationExceptions

    - by qntmfred
    I am using a third party web service that offers the following calls and responses http://api.athirdparty.com/rest/foo?apikey=1234 <response> <foo>this is a foo</foo> </response> and http://api.athirdparty.com/rest/bar?apikey=1234 <response> <bar>this is a bar</bar> </response> This is the contract and supporting types I wrote [ServiceContract] [XmlSerializerFormat] public interface IFooBarService { [OperationContract] [WebGet( BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "foo?key={apikey}")] FooResponse GetFoo(string apikey); [OperationContract] [WebGet( BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "bar?key={apikey}")] BarResponse GetBar(string apikey); } [XmlRoot("response")] public class FooResponse { [XmlElement("foo")] public string Foo { get; set; } } [XmlRoot("response")] public class BarResponse { [XmlElement("bar")] public string Bar { get; set; } } and then my client looks like this static void Main(string[] args) { using (WebChannelFactory<IFooBarService> cf = new WebChannelFactory<IFooBarService>("thirdparty")) { var channel = cf.CreateChannel(); FooResponse result = channel.GetFoo("1234"); } } When I run this I get the following exception Unable to deserialize XML body with root name 'response' and root namespace '' (for operation 'GetFoo' and contract ('IFooBarService', 'http://tempuri.org/')) using XmlSerializer. Ensure that the type corresponding to the XML is added to the known types collection of the service. If I comment out the GetBar operation from IFooBarService, it works fine. I know I'm missing an important concept here - just don't know quite what to look for. What is the proper way to construct my contract types, so that they can be properly deserialized?

  • Trouble with LINQ databind to GridView and RowDataBound

    - by Michael
    Greetings all, I am working on redesigning my personal Web site using VS 2008 and have chosen to use LINQ to create by data-access layer. Part of my site will be a little app to help manage my budget better. My first LINQ query does successfully execute and display in a GridView, but when I try to use a RowDataBound event to work with the results and refine them a bit, I get the error: The type or namespace name 'var' could not be found (are you missing a using directive or an assembly reference?) This interesting part is, if I just try to put in a var s = "s"; anywhere else in the same file, I get the same error too. If I go to other files in the web project, var s = "s"; compiles fine. Here is the LINQ Query call: public static IQueryable pubGetRecentTransactions(int param_accountid) { clsDataContext db; db = new clsDataContext(); var query = from d in db.tblMoneyTransactions join p in db.tblMoneyTransactions on d.iParentTransID equals p.iTransID into dp from p in dp.DefaultIfEmpty() where d.iAccountID == param_accountid orderby d.dtTransDate descending, d.iTransID ascending select new { d.iTransID, d.dtTransDate, sTransDesc = p != null ? p.sTransDesc : d.sTransDesc, d.sTransMemo, d.mTransAmt, d.iCheckNum, d.iParentTransID, d.iReconciled, d.bIsTransfer }; return query; } protected void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { this.prvLoadData(); } } internal void prvLoadData() { prvCtlGridTransactions.DataSource = clsMoneyTransactions.pubGetRecentTransactions(2); prvCtlGridTransactions.DataBind(); } protected void prvCtlGridTransactions_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { var datarow = e.Row.DataItem; var s = "s"; e.Row.Cells[0].Text = datarow.dtTransDate.ToShortDateString(); e.Row.Cells[1].Text = datarow.sTransDesc; e.Row.Cells[2].Text = datarow.mTransAmt.ToString("c"); e.Row.Cells[3].Text = datarow.iReconciled.ToString(); }//end if }//end RowDataBound My googling to date hasn't found a good answer, so I turn it over to this trusted community. I appreciate your time in assisting me.

  • StringTokenizer split at "<br/>"

    - by AnAmuser
    Maybe I am stupid but I don't understand why the behaviour of StringTokenizer here: import static org.apache.commons.lang.StringEscapeUtils.escapeHtml; String object = (String) value; String escaped = escapeHtml(object); StringTokenizer tokenizer = new StringTokenizer(escaped, escapeHtml("<br/>")); If fx. value is Hej<br/>$user.get(0).name Har vundet<br/><table border='1'><tr><th>Name</th><th>Played</th><th>Brewed</th></tr>#foreach( $u in $user )<tr><td>$u.name</td> <td>$u.played</td> <td>$u.brewed</td></tr>#end</table><br/> Then the result is Hej $use . e (0).name Ha vunde a e o de ='1' h Name h h P ayed h h B ewed h #fo each( $u in $use ) d $u.name d d $u.p ayed d d $u. ewed d #end a e It makes no sense to me. How can I make it behave as I expect to.

  • String.Format Phone Numbers with Extension

    - by ChiliYago
    I am trying to create a an function that formats US phone numbers -- hopefully without looping through each digit. When 10 digits are passed in all is fine. How ever when more than 10 digits are passed in I want the String.Format method to append the extension digits on the right. For example: When 14 digits passed in the result should be:(444)555-2222 x8888 When 12 digits passed in the result should be:(444)555-2222 x88 etc. However what I get with my current attempt is: Passing in 12 digits returns this string '() -949 x555444433' here is what I have so far. public static string _FormatPhone(object phonevalue) { Int64 phoneDigits; if (Int64.TryParse(phonevalue.ToString(), out phoneDigits)) { string cleanPhoneDigits = phoneDigits.ToString(); int digitCount = cleanPhoneDigits.Length; if (digitCount == 10) return String.Format("{0:(###) ###-####}", phoneDigits); else if (digitCount > 10) return String.Format("{0:(###) ###-#### x#########}", phoneDigits); else return cleanPhoneDigits; } return "Format Err#"; } Thanks in advance.

  • How to add XmlInclude attribute dynamically

    - by Anindya Chatterjee
    I have the following classes [XmlRoot] public class AList { public List<B> ListOfBs {get; set;} } public class B { public string BaseProperty {get; set;} } public class C : B { public string SomeProperty {get; set;} } public class Main { public static void Main(string[] args) { var aList = new AList(); aList.ListOfBs = new List<B>(); var c = new C { BaseProperty = "Base", SomeProperty = "Some" }; aList.ListOfBs.Add(c); var type = typeof (AList); var serializer = new XmlSerializer(type); TextWriter w = new StringWriter(); serializer.Serialize(w, aList); } } Now when I try to run the code I got an InvalidOperationException at last line saying that The type XmlTest.C was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically. I know that adding a [XmlInclude(typeof(C))] attribute with [XmlRoot] would solve the problem. But I want to achieve it dynamically. Because in my project class C is not known prior to loading. Class C is being loaded as a plugin, so it is not possible for me to add XmlInclude attribute there. I tried also with TypeDescriptor.AddAttributes(typeof(AList), new[] { new XmlIncludeAttribute(c.GetType()) }); before var type = typeof (AList); but no use. It is still giving the same exception. Does any one have any idea on how to achieve it?

  • event flow in action script 3

    - by Shay
    i try to dispatch a custom event from some component on the stage and i register other component to listen to it but the other component doesn't get the event here is my code what do i miss public class Main extends MovieClip //main document class { var compSource:Game; var compMenu:Menu; public function Main() { compSource = new Game; compMenu = new Menu(); var mc:MovieClip = new MovieClip(); addChild(mc); mc.addChild(compSource); // the source of the event - event dispatch when clicked btn mc.addChild(compMenu); //in init of that Movie clip it add listener to the compSource events } } public class Game extends MovieClip { public function Game() { btn.addEventListener(MouseEvent.CLICK, onFinishGame); } private function onFinishGame(e:MouseEvent):void { var score:Number = Math.random() * 100 + 1; dispatchEvent(new ScoreChanged(score)); } } public class Menu extends MovieClip { //TextField score public function Menu() { addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event):void { removeEventListener(Event.ADDED_TO_STAGE, init); //on init add listener to event ScoreChanged addEventListener(ScoreChanged.SCORE_GAIN, updateScore); } public function updateScore(e:ScoreChanged):void { //it never gets here! tScore.text = String(e._score); } } public class ScoreChanged extends Event { public static const SCORE_GAIN:String = "SCORE_GAIN"; public var _score:Number; public function ScoreChanged( score:Number ) { trace("new score"); super( SCORE_GAIN, true); _score = score; } } I don't want to write in Main compSource.addEventListener(ScoreChanged.SCORE_GAIN, compMenu.updateScore); cause i dont want the the compSource will need to know about compMenu its compMenu responsibility to know to what events it needs to listen.... any suggestions? Thanks!

  • Utilizing Windows Handles without a forum.

    - by Scott Chamberlain
    I have a program that needs to sit in the background and when a user connects to a RDP session it will do some stuff then launch a program. when the program is closed it will do some housekeeping and logoff the session. The current way I am doing it is like this I have the terminal server launch this application. I have it set as a windows forms application and my code is this public static void Main() { //Do some setup work Process proc = new Process(); //setup the process proc.Start(); proc.WaitForExit(); //Do some housecleaning NativeMethods.ExitWindowsEx(0, 0); } I really like this because there is no item in the taskbar and there is nothing showing up in alt-tab. However to do this I gave up access to functions like void WndProc(ref Message m) So Now I can't listen to windows messages (Like WTS_REMOTE_DISCONNECT or WTS_SESSION_LOGOFF) and do not have a handle to use for for bool WTSRegisterSessionNotification(IntPtr hWnd, int dwFlags); I would like my code to be more robust so it will do the housecleaning if the user logs off or disconnects from the session before he closes the program. Any reccomendations on how I can have my cake and eat it too?

  • How to remove the file suffix/extension (.jsp and .action) using the Stripes Framework?

    - by Dolph Mathews
    I'm looking to use pretty / clean URL's in my web app. I would like the following URL: http://mydomain.com/myapp/calculator .. to resolve to: com.mydomain.myapp.action.CalculatorActionBean I tried overwriting the NameBasedActionResolver with: public class CustomActionResolver extends NameBasedActionResolver { public static final String DEFAULT_BINDING_SUFFIX = "."; @Override protected String getBindingSuffix() { return DEFAULT_BINDING_SUFFIX; } @Override protected List<String> getActionBeanSuffixes() { List<String> suffixes = new ArrayList<String>(super.getActionBeanSuffixes()); suffixes.add(DEFAULT_BINDING_SUFFIX); return suffixes; } } And adding this to web.xml: <servlet-mapping> <servlet-name>StripesDispatcher</servlet-name> <url-pattern>*.</url-pattern> </servlet-mapping> Which gets me to: http://mydomain.com/myapp/Calculator. But: A stray "." is still neither pretty nor clean. The class name is still capitalized in the URL..? That still leaves me with *.jsp..? Is it even possible to get rid of both .action and .jsp?

  • Print a string that contains a certain pattern in Java

    - by jjpotter
    I am trying to find a regular expression within a line of a .csv file, so I can eventually save all the matches to another file, and lose all the other junk. So a line in my file might look like: MachineName,User,IP,VariableData,Location The VariableData is what I want to match, and if there's a match, print the line. I am using a pattern for this because I only want 3 out of 10 of variations of VariableData, and out of those 3, they are numbered differently(example, "pc104, pccrt102, pccart65"). I am trying to do this using the Scanner Class and keeping it simple as possible so I can understand it. Here is where I was heading with this...(the pattern isn't complete, just have it like this for testing). import java.io.File; import java.util.Scanner; import java.util.regex.Pattern; public class pcv { public static void main(String[] args) { File myFile = new File("c:\\temp\\report.csv"); Pattern myPat = Pattern.compile("pc"); try{ Scanner myScan = new Scanner(myFile); while(myScan.hasNext()){ if(myScan.hasNext(myPat)){ System.out.println("Test"); } } }catch(Exception e){ } } } This code loops, im guessing the .hasNext() methods are resetting themselves. I've played around with the Matcher class a little bit, but only found a way to match the expression but not get the whole line. My other throught was maybe somehow count the line that contains the pattern, then go back and print the line that corresponds to the counts.

  • C++ -- Is there an implicit cast here from Fred* to auto_ptr<Fred>?

    - by q0987
    Hello all, I saw the following code, #include <new> #include <memory> using namespace std; class Fred; // Forward declaration typedef auto_ptr<Fred> FredPtr; class Fred { public: static FredPtr create(int i) { return new Fred(i); // Is there an implicit casting here? If not, how can we return // a Fred* with return value as FredPtr? } private: Fred(int i=10) : i_(i) { } Fred(const Fred& x) : i_(x.i_) { } int i_; }; Please see the question listed in function create. Thank you // Updated based on comments Yes, the code cannot pass the VC8.0 error C2664: 'std::auto_ptr<_Ty::auto_ptr(std::auto_ptr<_Ty &) throw()' : cannot convert parameter 1 from 'Fred *' to 'std::auto_ptr<_Ty &' The code was copied from the C++ FAQ 12.15. However, after making the following changes, replace return new Fred(i); with return auto_ptr<Fred>(new Fred(i)); This code can pass the VC8.0 compiler. But I am not sure whether or not this is a correct fix.

  • Why not lump all service classes into a Factory method (instead of injecting interfaces)?

    - by Andrew
    We are building an ASP.NET project, and encapsulating all of our business logic in service classes. Some is in the domain objects, but generally those are rather anemic (due to the ORM we are using, that won't change). To better enable unit testing, we define interfaces for each service and utilize D.I.. E.g. here are a couple of the interfaces: IEmployeeService IDepartmentService IOrderService ... All of the methods in these services are basically groups of tasks, and the classes contain no private member variables (other than references to the dependent services). Before we worried about Unit Testing, we'd just declare all these classes as static and have them call each other directly. Now we'll set up the class like this if the service depends on other services: public EmployeeService : IEmployeeService { private readonly IOrderService _orderSvc; private readonly IDepartmentService _deptSvc; private readonly IEmployeeRepository _empRep; public EmployeeService(IOrderService orderSvc , IDepartmentService deptSvc , IEmployeeRepository empRep) { _orderSvc = orderSvc; _deptSvc = deptSvc; _empRep = empRep; } //methods down here } This really isn't usually a problem, but I wonder why not set up a factory class that we pass around instead? i.e. public ServiceFactory { virtual IEmployeeService GetEmployeeService(); virtual IDepartmentService GetDepartmentService(); virtual IOrderService GetOrderService(); } Then instead of calling: _orderSvc.CalcOrderTotal(orderId) we'd call _svcFactory.GetOrderService.CalcOrderTotal(orderid) What's the downfall of this method? It's still testable, it still allows us to use D.I. (and handle external dependencies like database contexts and e-mail senders via D.I. within and outside the factory), and it eliminates a lot of D.I. setup and consolidates dependencies more. Thanks for your thoughts!

  • How do I get my code to read the spaces between longs?

    - by WahtsUpWorld
    I apologize for any inconvenience that may occur in answering my question, I'm fairly new to programming and I'm so far only in the last weeks of my community college Java I class. The problem I am facing is in my code of which I cannot seem to get the PrintWriter to address the spaces in between my longs' phone number and social security I.D. The entire code consists of two classes in which one pulls from the other the information needed to parse and present the file writer/print writer. Here is the entire code w/ the second class after it: public class FinalProjectGroup1 { public static void main(String[] args) { } public String name; public long ssid; public double pay; public String address; public long number; public void cleanUpConstructor() {} public FinalProjectGroup1(String name, String address, double pay, long ssid, long number){ this.name = name; this.pay = pay; this.ssid = ssid; this.address = address; this.number = number; cleanUpConstructor(); } public void setName(String name) { this.name = name; } public String getName() { return name; } public void setPay(double pay) { this.pay = pay; } public double getPay() { return pay; } public void setSSID(long ssid) { this.ssid = ssid; } public long getSSID() { return ssid; } public void setAddress(String address) { this.address = address; } public String getAddress() { return address;

  • Dependency Injection Question - ASP.NET

    - by Paul
    I'm starting a web application that contains the following projects: Booking.Web Booking.Services Booking.DataObjects Booking.Data I'm using the repository pattern in my data project only. All services will be the same, no matter what happens. However, if a customer wants to use Access, it will use a different data repository than if the customer wants to use SQL Server. I have StructureMap, and want to be able to do the following: Web project is unaffected. It's a web forms application that will only know about the services project and the dataobjects project. When a service is called, it will use StructureMap (by looking up the bootstrapper.cs file) to see which data repository to use. An example of a services class is the error logging class: public class ErrorLog : IErrorLog { ILogging logger; public ErrorLog() { } public ErrorLog(ILogging logger) { this.logger = logger; } public void AddToLog(string errorMessage) { try { AddToDatabaseLog(errorMessage); } catch (Exception ex) { AddToFileLog(ex.Message); } finally { AddToFileLog(errorMessage); } } private void AddToDatabaseLog(string errorMessage) { ErrorObject error = new ErrorObject { ErrorDateTime = DateTime.Now, ErrorMessage = errorMessage }; logger.Insert(error); } private void AddToFileLog(string errorMessage) { // TODO: Take this value from the web.config instead of hard coding it TextWriter writer = new StreamWriter(@"E:\Work\Booking\Booking\Booking.Web\Logs\ErrorLog.txt", true); writer.WriteLine(DateTime.Now.ToString() + " ---------- " + errorMessage); writer.Close(); } } I want to be able to call this service from my web project, without defining which repository to use for the data access. My boostrapper.cs file in the services project is defined as: public class Bootstrapper { public static void ConfigureStructureMap() { ObjectFactory.Initialize(x => { x.AddRegistry(new ServiceRegistry()); } ); } public class ServiceRegistry : Registry { protected override void configure() { ForRequestedType<IErrorLog>().TheDefaultIsConcreteType<Booking.Services.Logging.ErrorLog>(); ForRequestedType<ILogging>().TheDefaultIsConcreteType<SqlServerLoggingProvider>(); } } } What else do I need to get this to work? When I defined a test, the ILogger object was null. Thanks,

  • ObjectContext disposed puzzle

    - by jaklucky
    Hi, I have the follwing method. public List<MyEntity> GetMyEntities(MyObjectContext objCtx) { using(MyObjectContext ctx = objCtx ?? new MyObjectContext()) { retun ctx.MyEntities.ToList(); } } The idea is, user of this method can pass in the objectcontext if they have. If not then a new objectcontext will be created. If I am passing an object context to it, then it is getting disposed after the method is done. I was expecting only "ctx" variable gets disposed. If I write a small app, to know the using and dispose mechanism. It is acting differently. class TestClass : IDisposable { public int Number { get; set; } public string Str { get; set; } public ChildClass Child { get; set; } #region IDisposable Members public void Dispose() { Console.WriteLine("Disposed is called"); } #endregion } class ChildClass : IDisposable { public string StrChild { get; set; } #region IDisposable Members public void Dispose() { Console.WriteLine("Child Disposed is called"); } #endregion } class Program { static void Main(string[] args) { TestClass test = null; test = new TestClass(); test.Child = new ChildClass(); using (TestClass test1 = test ?? new TestClass()) { test1.Number = 1; test1.Str = "hi"; test1.Child.StrChild = "Child one"; test1.Child.Dispose(); } test.Str = "hi"; test.Child.StrChild = "hi child"; Console.ReadLine(); } } In this example, "test1"gets disposed but not "test". Where as in the first case both ctx and objCtx get disposed. Any ideas what is happening here with objectContext? Thank you, Suresh

  • My Rails app is returning HTTP 500 for all its URLs, but nothing shows up in the log file. How can I

    - by mipadi
    I have a Rails app that is running on a production server with Apache and Phusion Passenger. The app works fine locally when using Mongrel, but whenever I try to load a URL on the production server, it returns HTTP 500. I know the server is working properly, because I can get the static elements of the application (e.g., JavaScript files, stylesheets, images) just fine. I've also checked the Passenger status and it is loading the app (it must be, since the app's 500 Internal Server Error page is returned, not just the default Apache one). Also, when I load the app via script/console production and do something like app.get("/"), 500 is also returned. The problem is that there is nothing in the log files to indicate the problem. production.log is empty. The Apache error logs show no problems with Apache, either. I'm stumped as to what's going on and I'm not sure how to diagnose the problem. I know I may have been a bit vague, but can anyone give a suggestion on what the problem may be? Or at least a way I can go about diagnosing it?

  • Asp.net MVC error with custom HttpModule

    - by Robert Koritnik
    I have a custom authentication HttpModule that is pretty strait forward. But I want it to run only for managed requests (and not for static ones). Asp.net MVC automatically adds configuration section for IIS7 web server: <system.webServer> <validation validateIntegratedModeConfiguration="false" /> <modules runAllManagedModulesForAllRequests="true"> <remove name="ScriptModule" /> <remove name="UrlRoutingModule" /> <add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule,..." /> <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule,..." /> </modules> <handlers> ... </handlers> </system.webServer> When I add my own module I also set its preCondition="managedHandler", but since there's runAllManagedModulesForAllRequests="true" on parent <module> element my preCondition is ignored by design (as I read on MSDN). When I try to set though: <modules runAllManagedModulesForAllRequests="false"> I get this error: [image no longer valid] What else (which other module) do I have to set in web.config to make it work with this setting: <modules runAllManagedModulesForAllRequests="false">

  • Android Web App : Position:fixed broken?

    - by StevenGilligan
    Hi all, I'm in the process of developping a Web Application for mobiles. I went with web applications because to me it seems a winning situation having to develop one application that could run also on iPhone / Windows Mobile / Palm etc. I started testing today after a few days of doing concepts, ideas and designs and what I wanted to do was have a menu that sticks at the bottom of the page. Exactly like the menu on the bottom in this iPhone application screenshot : http://farm4.static.flickr.com/3094/2656904921_1c54e93b4f.jpg Using CSS, I though it would be really easy to do this. Only using position:fixed; bottom:0; would have done the trick but I have found it doesn't behave the same on mobile browsers I tried to split my page in 2 sections : 1 would be a scrollable div (for the content) and the other one would be the bottom menu. Scrollable divs also do not work on Android. I also tried using frames with no luck either. Does anyone know of any way to re-create a menu that would stick to the bottom of a page for mobile phones? Thank you, Steven

  • JAXB does not call setter when unmarshalling objects

    - by Yaneeve
    Hi all, I am using JAXB 2.0 JDK 6 in order to unmarshall an XML instance into POJOs. In order to add some custom validation I have inserted a validation call into the setter of a property, yet despite it being private, it seems that the unmarshaller does not call the setter but directly modifies the private field. It is crucial to me that the custom validation occurs for this specific field every unmarshall call. What should I do? Code: @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "LegalParams", propOrder = { "value" }) public class LegalParams { private static final Logger LOG = Logger.getLogger(LegalParams.class); @XmlTransient private LegalParamsValidator legalParamValidator; public LegalParams() { try { WebApplicationContext webApplicationContext = ContextLoader.getCurrentWebApplicationContext(); LegalParamsFactory legalParamsFactory = (LegalParamsFactory) webApplicationContext.getBean("legalParamsFactory"); HttpSession httpSession = SessionHolder.getInstance().get(); legalParamValidator = legalParamsFactory.newLegalParamsValidator(httpSession); } catch (LegalParamsException lpe) { LOG.warn("Validator related error occurred while attempting to construct a new instance of LegalParams"); throw new IllegalStateException("LegalParams creation failure", lpe); } catch (Exception e) { LOG.warn("Spring related error occurred while attempting to construct a new instance of LegalParams"); throw new IllegalStateException("LegalParams creation failure", e); } } @XmlValue private String value; /** * Gets the value of the value property. * * @return * possible object is * {@link String } * */ public String getValue() { return value; } /** * Sets the value of the value property. * * @param value * allowed object is * {@link String } * @throws TestCaseValidationException * */ public void setValue(String value) throws TestCaseValidationException { legalParamValidator.assertValid(value); this.value = value; } }

  • printf and Console.WriteLine - problems with Console.SetOut?

    - by Matt Jacobsen
    i have a bunch of Console.WriteLines in my code that I can observe at runtime. I communicate with a native library that I also wrote. I'd like to stick some printf's in the native library and observe them too. I don't see them at runtime however. I've created a convoluted hello world app to demonstrate my problem. When the app runs, I can debug into the native library and see that the hello world is called. The output never lands in the textwriter though. Note that if the same code is run as a console app then everything works fine. C#: [DllImport("native.dll")] static extern void Test(); StreamWriter writer; public Form1() { InitializeComponent(); writer = new StreamWriter(@"c:\output.txt"); writer.AutoFlush = true; System.Console.SetOut(writer); } private void button1_Click(object sender, EventArgs e) { Test(); } and the native part: __declspec(dllexport) void Test() { printf("Hello World"); } Despite my earlier ramblings (see edits) I actually think this is a problem in C# (or rather my understanding of it).

  • Cascading input control is empty while accessing a Jasper Report

    - by Yogesh R
    I call a jasper report through an independent URL through which I pass one of the input controls needed to run the report. E.g. http:// localhost:8080/jasperserver/flow.html?_flowId=viewReportFlow&standAlone=true&reportUnit=xyz&ParentFolderUri=abcd&j_username=xyz&j_password=xyz&parameter1=value1& . . . As you can see in the URL, I pass the JasperServer username and password, reportUnit name and location and other mandatory parameters, along with the report input parameter, i.e., "parameter1" which can have a value like "value1". I used a mandatory, read-only and visible input control for this input value. Its value would come from the URL, showed in the box but was read-only and hence could not be changed. The report was working absolutely fine upto this point. But the tragedy began when my client rejected this idea. He wanted a completely invisible input control to my report and the input value would be passed through the URL, just like illustrated above. And then my client asked me to refer to this and made me work on cascading input controls. Recently I added a cascading input control to this report. The input control type is a single select query, which utilizes two parameters that I pass to the report through the URL. Now when the Jasper server responds to the URL with the input parameters, all the other static parameters work properly, except for the cascaded one. When I click the select box of the cascaded input, I can see the desired options for a second, and then, it just goes empty while I'm viewing the select list. But when I make the "Parameter1" input control visible, the cascading input control works! And then I turn in invisible, the cascading input control turns into a beast that does things by itself and not listen to his master. I am not able to understand why this is happening. Could anybody please provide me a solution to this?
