  • EJB3 + JEE6: What is a persistent Timer?

    - by Hank
    I'm just about to use the new EJB3 TimerService (as part of Java EE 6), and as usual, I'm impressed by the brevity of JavaDoc :) Do you know what is the effect of the persistent property of the TimerConfig object? JavaDoc TimerConfig says: The persistent property determines whether the corresponding timer has a lifetime that spans the JVM in which it was created. It is optional and defaults to true.

  • XStream parse attributes and values at the same time

    - by gurbieta
    Hi, I have the following XML <search ver="3.0"> <loc id="ARBA0009" type="1">Buenos Aires, Argentina</loc> <loc id="BRXX1283" type="1">Buenos Aires, Brazil</loc> <loc id="ARDF0127" type="1">Aeroparque Buenos Aires, Argentina</loc> <loc id="MXJO0669" type="1">Concepcion De Buenos Aires, Mexico</loc> <loc id="MXPA1785" type="1">San Nicolas De Buenos Aires, Mexico</loc> <loc id="ARBA0005" type="1">Balcarce, Argentina</loc> <loc id="ARBA0008" type="1">Bragado, Argentina</loc> <loc id="ARBA0010" type="1">Campana, Argentina</loc> <loc id="ARBA0016" type="1">Chascomus, Argentina</loc> <loc id="ARBA0019" type="1">Chivilcoy, Argentina</loc> </search> And a City class public class City { private String id; private Integer type; private String name; // getters & setters... } I tried the following aliases to parse the XML xStream.alias("search", List.class); xStream.alias("loc", City.class); xStream.useAttributeFor("id", String.class); xStream.useAttributeFor("type", Integer.class); But I can't figure out how to set the value of the "loc" tag, if I try to transform the City object in XML I get <search> <loc id="ARBA0001" type="1"> <name>Buenos Aires</name> </loc> </search> When I really need to get this <search> <loc id="ARBA0001" type="1">Buenos Aires</loc> </search> Then, if I try to parse the XML to a City object I get the field "name" with a null value. Anybody knows how to set te correct aliases to do this? Thanks in advance.

  • Using Reflection.Emit to match existing constructor

    - by yodaj007
    First, here is the C# code and the disassembled IL: public class Program<T> { private List<T> _items; public Program(T x, [Microsoft.Scripting.ParamDictionary] Microsoft.Scripting.IAttributesCollection col) { _items = new List<T>(); _items.Add(x); } } Here is the IL of that constructor: .method public hidebysig specialname rtspecialname instance void .ctor(!T x, class [Microsoft.Scripting]Microsoft.Scripting.IAttributesCollection col) cil managed { .param [2] .custom instance void [Microsoft.Scripting]Microsoft.Scripting.ParamDictionaryAttribute::.ctor() = ( 01 00 00 00 ) // Code size 34 (0x22) .maxstack 8 IL_0000: ldarg.0 IL_0001: call instance void [mscorlib]System.Object::.ctor() IL_0006: nop IL_0007: nop IL_0008: ldarg.0 IL_0009: newobj instance void class [mscorlib]System.Collections.Generic.List`1<!T>::.ctor() IL_000e: stfld class [mscorlib]System.Collections.Generic.List`1<!0> class Foo.Program`1<!T>::_items IL_0013: ldarg.0 IL_0014: ldfld class [mscorlib]System.Collections.Generic.List`1<!0> class Foo.Program`1<!T>::_items IL_0019: ldarg.1 IL_001a: callvirt instance void class [mscorlib]System.Collections.Generic.List`1<!T>::Add(!0) IL_001f: nop IL_0020: nop IL_0021: ret } // end of method Program`1::.ctor I am trying to understand the IL code by emitting it myself. This is what I have managed to emit: .method public hidebysig specialname rtspecialname instance void .ctor(!T A_1, class [Microsoft.Scripting]Microsoft.Scripting.IAttributesCollection A_2) cil managed { // Code size 34 (0x22) .maxstack 4 IL_0000: ldarg.0 IL_0001: call instance void [mscorlib]System.Object::.ctor() IL_0006: ldarg.0 IL_0007: newobj instance void class [mscorlib]System.Collections.Generic.List`1<!T>::.ctor() IL_000c: stfld class [mscorlib]System.Collections.Generic.List`1<!0> class MyType<!T>::_items IL_0011: ldarg.0 IL_0012: ldfld class [mscorlib]System.Collections.Generic.List`1<!0> class MyType<!T>::_items IL_0017: ldarg.s A_1 IL_0019: nop IL_001a: nop IL_001b: nop IL_001c: callvirt instance void class [mscorlib]System.Collections.Generic.List`1<!T>::Add(!0) IL_0021: ret } // end of method MyType::.ctor There are a few differences that I just can't figure out. I'm really close... How do I take care of the parameter attribute (ParamDictionaryAttribute)? I can't find a 'custom' opcode. Is the .param [2] important? How do I emit that? Why is the C# code stack size 8, while my emitted version is 4? Is this important?

  • WPF - Redrawing a Context Menu when Items change?

    - by Rachel
    I have a ItemsControl in a ScrollViewer, and when the items exceed the width of the ScrollViewer they are put into a ContextMenu and shown as a DropDown instead. My problem is that when the Context Menu is first loaded, it saves the saves the size of the Menu and does not redraw when more commands get added/removed. For example, a panel has 3 commands. 1 is visible and 2 are in the Menu. Viewing the menu shows the 2 commands and draws the control, but then if you resize the panel so 2 are visible and only 1 command is in the menu, it doesn't redraw the menu to eliminate that second menu item. Or even worse, if you shrink the panel so that no commands are shown and all 3 are in the Menu, it will only show the top 2. Here's my code: <Button Click="DropDownMenu_Click" ContextMenuOpening="DropDownMenu_ContextMenuOpening"> <Button.ContextMenu> <ContextMenu ItemsSource="{Binding Path=MenuCommands}" Placement="Bottom"> <ContextMenu.Resources> <Style TargetType="{x:Type MenuItem}"> <Setter Property="Command" Value="{Binding Path=Command}" /> <Setter Property="Visibility" Value="{Binding Path=IsVisible, Converter={StaticResource ReverseBooleanToVisibilityConverter}}"/> </Style> </ContextMenu.Resources> <ContextMenu.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding Path=DisplayName}" /> </DataTemplate> </ContextMenu.ItemTemplate> </ContextMenu> </Button.ContextMenu> </Button> Code Behind: void DropDownMenu_ContextMenuOpening(object sender, ContextMenuEventArgs e) { Button b = sender as Button; b.ContextMenu.IsOpen = false; e.Handled = true; } private void DropDownMenu_Click(object sender, RoutedEventArgs e) { Button b = sender as Button; ContextMenu cMenu = b.ContextMenu; if (cMenu != null) { cMenu.PlacementTarget = b; cMenu.Placement = System.Windows.Controls.Primitives.PlacementMode.Bottom; } } I have tried using InvalidateVisual and passing an empty delegate on Render to try and force a redraw, however neither works. I'm using .Net 4.0.

  • NHibernate many-to-many with composite element

    - by E1
    Hello everyone. I encountered the following problem. In my application uses the entities Owner and Area binding as many to many. public class Area : DomainObject<int> { private ISet<OwnersPeriod> _owners = new HashedSet<OwnersPeriod>(); public ICollection<OwnersPeriod> Owners { get { return _owners; } set { Check.Require(value != null); _owners = new HashedSet<OwnersPeriod>(value); } } } Table Owner2Area has the following fields: CREATE TABLE [dbo].[Owner2Area]( [ID] [int] IDENTITY(1,1) NOT NULL, [IDOwner] [int] NOT NULL, [IDArea] [int] NOT NULL, [FirstDate] [datetime] NOT NULL, [LastDate] [datetime] NULL, CONSTRAINT [PK_Owner2Area] PRIMARY KEY CLUSTERED) Therefore corresponds to the class OwnersPeriod public class OwnersPeriod { private Owner _member; private Area _area; public Owner Owner { get {...} set{...} } public Area Area { get { ... } set { ... } } public DateTime FirstDate { get; set; } public DateTime? LastDate { get; set; } } I wrote mappings <class lazy="false" name="Core.Domain.Area, Core" table="Areas"> ... <set name="Owners" table="Owner2Area" inverse="true" lazy="true" > <key column="IDArea"/> <composite-element class="Core.Domain.OwnersPeriod, Core" > <parent name="Area" /> <property name="FirstDate" type="datetime"/> <property name="LastDate" type="datetime"/> <many-to-one name="Owner" class="Core.Domain.Owner, Core" column="IDOwner"/> </composite-element> </set> </class> For each area existing data are successfully loaded into Owners, but when I add new record in Owner2Area through CreateSQLQuery, these data are not updated for instance of area. If I re-opened the form and got all areas, added link successfully loaded into the collection. How can be forced to load added thus recording of relation many-to-many?

  • Why does a user have to enter "Profile" data to enter data into other tables?

    - by Greg McNulty
    EDIT It appears the user has to enter some data for his profile, otherwise I get this error below. I guess if there is no profile data, the user can not continue to enter data in other tables by default? I do not want to make entering user profile data a requirement to use the rest of the sites functionality, how can I get around this? Currently I have been testing everything with the same user and everything has been working fine. However, when I created a new user for the very first time and tried to enter data into my custom table, I get the following error. The INSERT statement conflicted with the FOREIGN KEY constraint "FK_UserData_aspnet_Profile". The conflict occurred in database "C:\ISTATE\APP_DATA\ASPNETDB.MDF", table "dbo.aspnet_Profile", column 'UserId'. The statement has been terminated. Not sure why I am getting this error. I have the user controls set up in ASP.NET 3.5 however all I am using is my own table or at least that I am aware of. I have a custom UserData table that includes the columns: id, UserProfileID, CL, LL, SL, DateTime (id is the auto incremented int) The intent is that all users will add their data in this table and as I mentioned above it has been working fine for my original first user I created. However, when i created a new user I am getting this problem. Here is the code that updates the database. protected void Button1_Click(object sender, EventArgs e) { //connect to database MySqlConnection database = new MySqlConnection(); database.CreateConn(); //create command object Command = new SqlCommand(queryString, database.Connection); //add parameters. used to prevent sql injection Command.Parameters.Add("@UID", SqlDbType.UniqueIdentifier); Command.Parameters["@UID"].Value = Membership.GetUser().ProviderUserKey; Command.Parameters.Add("@CL", SqlDbType.Int); Command.Parameters["@CL"].Value = InCL.Text; Command.Parameters.Add("@LL", SqlDbType.Int); Command.Parameters["@LL"].Value = InLL.Text; Command.Parameters.Add("@SL", SqlDbType.Int); Command.Parameters["@SL"].Value = InSL.Text; Command.ExecuteNonQuery(); } Source Error: Line 84: Command.ExecuteNonQuery();

  • More efficient programming than Web.py?

    - by Luke Stanley
    I love webpy, it's really quite Pythonic but I don't like having to add the url mappings and create a class, typically with just 1 function inside it. I'm interested in minimising code typing and prototyping fast. Does anyone have any up and coming suggestions such as Bobo, Bottle, Denied, cherrypy for a lover of webpy's good things? What makes it a good reason? Also I don't mind missing out (strongly) text based templating systems, I use object oriented HTML generation.

  • MediaElement fails after several plays.

    - by basilkot
    Hi! I have a problem with MediaElement control. I've put six MediaElements on my form, then I start them and change played files by timer. After several times, these elements stop playing. Here is the sample XAML: <Grid> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <MediaElement x:Name="element1" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="0" Grid.Row="0" /> <MediaElement x:Name="element2" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="1" Grid.Row="0" /> <MediaElement x:Name="element3" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="2" Grid.Row="0" /> <MediaElement x:Name="element4" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="0" Grid.Row="1" /> <MediaElement x:Name="element5" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="1" Grid.Row="1" /> <MediaElement x:Name="element6" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="2" Grid.Row="1" /> Here is the sample code: // The code below repeats for each MediaElement List<string> playlist1 = new List<string>() { @"file1.wmv", @"file2.wmv", @"file3.wmv", @"file4.wmv" }; DispatcherTimer timer1 = null; int index1 = 0; ... void Window1_Loaded(object sender, RoutedEventArgs e) { timer1 = new DispatcherTimer(); timer1.Tick += new EventHandler(timer1_Elapsed); timer1.Interval = TimeSpan.FromSeconds(10); element1.Source = new Uri(playlist1[index1]); timer1.Start(); element1.Play(); ... } void timer1_Elapsed(object sender, EventArgs e) { Dispatcher.BeginInvoke(DispatcherPriority.Normal, (System.Threading.ThreadStart)delegate() { element1.Stop(); element1.Close(); timer1.Stop(); index1++; if (index1 >= playlist1.Count) { index1 = 0; } element1.Source = new Uri(playlist1[index1]); timer1.Start(); element1.Play(); }); } ... Does anybody have similar problems?

  • ArrayList throwing exception on retrieval from google datastore (with gwt, java)

    - by sumeet
    I'm using Google Web Toolkit with java and google datastore as database. The entity class has arraylist and on trying to retrieve the data from data base I'm getting the exception: Type 'org.datanucleus.sco.backed.ArrayList' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized. I'm using JPA. Entity code: package com.ver2.DY.client; import java.io.Serializable; import java.util.ArrayList; import javax.jdo.annotations.IdGeneratorStrategy; import javax.jdo.annotations.PersistenceCapable; import javax.jdo.annotations.Persistent; import javax.jdo.annotations.PrimaryKey; import com.google.gwt.user.client.rpc.IsSerializable; @PersistenceCapable public class ChatInfo implements Serializable, IsSerializable{ @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Long topicId; @Persistent private String chatTopic; @Persistent private ArrayList messages = new ArrayList(); @Persistent private boolean isFirstPost; public ChatInfo() { } public Long getTopicId() { return topicId; } public void setTopicId(Long topicId) { this.topicId = topicId; } public String getChatTopic() { return chatTopic; } public void setChatTopic(String chatTopic) { this.chatTopic = chatTopic; } public ArrayList getMessages() { return messages; } public void addMessage(String newMsg) { messages.add(newMsg); } public boolean isFirstPost() { return isFirstPost; } public void setFirstPost(boolean isFirstPost) { this.isFirstPost = isFirstPost; } } Method in db class: @Transactional public ChatInfo[] getAllChat() { PersistenceManager pm = PMF.get().getPersistenceManager(); List chats = null; ChatInfo[] infos = null; String query = "select from " + ChatInfo.class.getName(); try{ chats = (List) pm.newQuery(query).execute(); infos = new ChatInfo[chats.size()]; for(int i=0;i } It is a bit strange because earlier I was able to insert and retrieve the data but it now throwing an exception. On searching the web I could find that I need to convert the Arraylist from some DataNucleus type to java util but not sure how to do that.

  • Expected output from an RM-1501 RS232 interface?

    - by Jon Cage
    I have an old RM-1501 digital tachometer which I'm using to try to identify the speed of an object. According to the manual I should be able to read the data over a serial link. Unfortunately, I don't appear to be able to get any sensible output from the device (never gives a valid speed). I think it might be a signalling problem because disconnecting the CTS line starts to get some data through.. Has anyone ever developed anything for one of these / had any success?

  • dz's Open Flash Chart 2 disabling animation problem (Rails)

    - by greg
    How to disable the startup animation in OFC2? Since I started using the dz build, the on-show animation is on by default, which sucks quite a lot. Neither of these work: graph.animate=false graph.on_show=false Also, dz's build implements the tooltip hover support poorly - the tooltip continues to hover even when the cursor is on another flash object. Has anyone overcome these problems?

  • Converting NSDecimalNumber to NSString

    I'm retrieving a key from an object that looks like this: po obj { TypeID = 3; TypeName = Asset; } The key value is being retrieved like this: NSString *typeId = (NSString*)[obj objectForKey:@"TypeID"]; Rather than typeId being an NSString, it is an NSDecimalNumber. Why is that? How do I convert it to an NSString?

  • Nhibernate: One-To-Many mapping problem - Cannot cascade delete without inverse. Set NULL error

    - by KnaveT
    Hi, I have the current scenario whereby an Article has only 1 Outcome each. Each Article may or may not have an Outcome. In theory, this is a one-to-one mapping, but since NHibernate does not really support one-to-one, I used a One-To-Many to substitute. My Primary Key on the child table is actually the ArticleID (FK). So I have the following setup: Classes public class Article { public virtual Int32 ID { get;set;} private ICollection<ArticleOutcome> _Outcomes {get;set;} public virtual ArticleOutcome Outcome { get { if( this._Outcomes !=null && this._Outcomes.Count > 0 ) return this._Outcomes.First(); return null; } set { if( value == null ) { if( this._Outcomes !=null && this._Outcomes.Count > 0 ) this._Outcomes.Clear(); } else { if( this._Outcomes == null ) this._Outcomes = new HashSet<ArticleOutcome>(); else if ( this._Outcomes.Count >= 1 ) this._Outcomes.Clear(); this._Outcomes.Add( value ); } } } } public class ArticleOutcome { public virtual Int32 ID { get;set; } public virtual Article ParentArticle { get;set;} } Mappings public class ArticleMap : ClassMap<Article> { public ArticleMap() { this.Id( x=> x.ID ).GeneratedBy.Identity(); this.HasMany<ArticleOutcome>( Reveal.Property<Article>("_Outcomes") ) .AsSet().KeyColumn("ArticleID") .Cascade.AllDeleteOrphan() //Cascade.All() doesn't work too. .LazyLoad() .Fetch.Select(); } } public class ArticleOutcomeMap : ClassMap<ArticleOutcome> { public ArticleOutcomeMap(){ this.Id( x=> x.ID, "ArticleID").GeneratedBy.Foreign("ParentArticle"); this.HasOne( x=> x.ParentArticle ).Constrained (); //This do not work also. //this.References( x=> x.ParentArticle, "ArticleID" ).Not.Nullable(); } } Now my problem is this: It works when I do an insert/update of the Outcome. e.g. var article = new Article(); article.Outcome = new ArticleOutcome { xxx = "something" }; session.Save( article ); However, I encounter SQL errors when attempting to delete via the Article itself. var article = session.Get( 123 ); session.Delete( article ); //throws SQL error. The error is something to the like of Cannot insert NULL into ArticleID in ArticleOutcome table. The deletion works if I place Inverse() to the Article's HasMany() mapping, but insertion will fail. Does anyone have a solution for this? Or do I really have to add a surrogate key to the ArticleOutcome table?

  • Cannot assign - must be a "UserProfile" instance

    - by webvulture
    I have a class UserProfile defined which takes the default user as a foreign key. Now another class A has a foreign key to UserProfile. So for saving any instance in class A, how do i give it the userprofile object. Also, does making a class UserProfile mean that class user is still used and class UserProfile is just some other table? I need to know this as I have to take care of the user profile creation, so I should know what gets stored where? -- Confused

Or... how can I run binding only when I done with all parameters ?

I never heard about this term before and google did not come up with useful result. What is that?

  • Print Preview Control used in a custom Print Preview Dialog.

    - by Kildareflare
    I have successfully implemented printing and print preview for my app using the PrintDocument, PrintDialog and PrintPreviewDialog classes of .NET. However my app uses a toolkit to improve the appearance of the standard .NET controls. There are versions of most .NET controls in the toolkit, but none for the Print controls. Therefore to ensure that the appearance of these controls matches the rest of the app I am creating a custom PrintPreviewDialog based on a toolkit form and embedding a .NET PrintPrewviewControl in it. My problem is that the PrintPreviewControl always shows "No pages to display". I had no trouble getting this to work using the .NET PrintPreviewDialog and cannot see what I am doing wrong. This is a .NET 2.0 PrintPreviewControl and so I know that I need to call InvalidatePreview() after assigning the PrintDocument. However it does not seem to matter where i place it, the PrintPage event handler never gets called... EDIT: I've just noticed that while the original PrintDocument m_printDocument shows a PrintPageHandler in its properties, the m_printPreviewControl.Document does not. Any ideas why it is being lost..? public class PrintEngine { ...rest of class... public PrintEngine() { m_printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage); } public void PrintPreview() { //ORIGINAL CODE USING .NET DIALOG WORK OK //PrintPreviewDialog dlg1 = new PrintPreviewDialog(); //dlg1.Document = m_printDoc; //PrepareImageForPrinting(); //dlg1.ShowDialog(); //CODE USING MY CUSTOM DIALOG DO NOT WORK? MyPrintPreviewDialog dlg2 = new MyPrintPreviewDialog(); dlg2.Document = m_printDoc; PrepareImageForPrinting(); //Creates the m_printImage List dlg2.ShowDialog(); } private void printDoc_PrintPage(object sender, PrintPageEventArgs e) { e.Graphics.DrawImage(m_printImages[m_currentPage], new Point(0, 0)); m_currentPage++; e.HasMorePages = m_currentPage < m_pagesHigh; } }//end PrintEngine class public class MyPrintPreviewDialog : KryptonForm { public PrintDocument Document { get { return m_printPreviewControl.Document; } set { m_printPreviewControl.Document = value; m_printPreviewControl.InvalidatePreview(); } } public MyPrintPreviewDialog() { InitializeComponent(); m_printPreviewControl = new PrintPreviewControl(); m_printPreviewControl.StartPage = 0; } private void MyPrintPreviewDialog_Load(object sender, EventArgs e) { m_printPreviewControl.Document.DefaultPageSettings = new PageSettings(); m_printPreviewControl.Document.PrinterSettings = new PrinterSettings(); m_printPreviewControl.InvalidatePreview(); } }//end MyPrintPreviewDialog class
