  • No properties file found Error for ReloadableResourceBundleMessageSource

    - by samspot
    I'm trying to use a reloadable spring resource bundle but spring cannot find the file. I've tried tons of different paths, but can't get it to work anywhere. In the code below you'll see that i load both the spring bundle and the regular one from the same path variable but only one works. I've been banging my head against this for far too long. Anybody have any ideas? logfile INFO 2010-04-28 11:38:31,805 [main] org.myorg.test.TestMessages: C:\www\htdocs\messages.properties INFO 2010-04-28 11:38:31,805 [main] org.myorg.data.Messages: initializing Spring Message Source to C:\www\htdocs\messages.properties INFO 2010-04-28 11:38:31,821 [main] org.myorg.data.Messages: Attempting to load properties from C:\www\htdocs\messages.properties DEBUG 2010-04-28 11:38:31,836 [main] org.springframework.context.support.ReloadableResourceBundleMessageSource: No properties file found for [C:\www\htdocs\messages.properties_en_US] - neither plain properties nor XML DEBUG 2010-04-28 11:38:31,842 [main] org.springframework.context.support.ReloadableResourceBundleMessageSource: No properties file found for [C:\www\htdocs\messages.properties_en] - neither plain properties nor XML DEBUG 2010-04-28 11:38:31,848 [main] org.springframework.context.support.ReloadableResourceBundleMessageSource: No properties file found for [C:\www\htdocs\messages.properties] - neither plain properties nor XML INFO 2010-04-28 11:38:31,848 [main] org.myorg.test.TestMessages: I am C:\www\htdocs\messages.properties Messages.java package org.myorg.data; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.util.PropertyResourceBundle; import java.util.ResourceBundle; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.springframework.context.support.ReloadableResourceBundleMessageSource; public class Messages { protected static final Log logger = LogFactory.getLog(Messages.class); private static ReloadableResourceBundleMessageSource msgSource = null; private static ResourceBundle RESOURCE_BUNDLE; public static final String PATH = "C:" + File.separator + "www" + File.separator + "htdocs" + File.separator + "messages.properties"; private Messages() { } public static String getString(String key) { initBundle(); return msgSource.getMessage(key, null, RESOURCE_BUNDLE.getString(key), null); } private static void initBundle(){ if(null == msgSource || null == RESOURCE_BUNDLE){ logger.info("initializing Spring Message Source to " + PATH); msgSource = new ReloadableResourceBundleMessageSource(); msgSource.setBasename(PATH); msgSource.setCacheSeconds(1); /* works, but you have to hardcode the platform dependent path starter.

  • Is it possible to create a generic Util Function to be used in Eval Page

    - by Nassign
    I am currently binding a Nullable bit column to a listview control. When you declare a list view item I need to handle the case when the null value is used instead of just true or false. <asp:Checkbox ID="Chk1" runat="server" Checked='<%# HandleNullableBool(Eval("IsUsed")) %>' /> Then in the page I add a HandleNullableBool() function inside the ASPX page. protected static bool HandleNullableBool(object value) { return (value == null) ? false : (bool)value; } This works fine but I need to use this in several pages so I tried creating a utility class with a static HandleNullableBool. But using it in the asp page does not work. Is there a way to do this in another class instead of the ASPX page? <asp:Checkbox ID="Chk1" runat="server" Checked='<%# Util.HandleNullableBool(Eval("IsUsed")) %>' />

  • Programmatically modifying an embedded resource before registering/referencing it on the page

    - by Jimock
    Hi All, Firstly, "Modifying" may be the wrong term, I see a few people have posted online just asking whether they can actually modify an embedded resource. What I am wanting to to, is use a resource in my assembly as a kind of template which I would do a find and replace on before registering it on the page - is this possible? For example; say I have a few lines of jQuery as an embedded resource in my assembly and in this script I am referencing a CSS class name that can be set by the front-end programmer. Since I do not know what the CSS class will be until implementation, is there a way of going through the embedded resource and replacing, say, $myclass$ with ThisClassName. Any help would be appreciated, if it's not possible then at least tell me so I can stop chasing my tail. Cheers, James

  • Using PyQt signals correctly

    - by Skilldrick
    A while ago I did some work in Qt for C++; now I'm working with PyQt. I have a subclass of QStackedWidget, and inside that a subclass of QWidget. In the QWidget I want to click a button that goes to the next page of the QStackedWidget. My (simplified) approach is as follows: class Stacked(QtGui.QStackedWidget): def __init__(self, parent=None): QtGui.QStackedWidget.__init__(self, parent) self.widget1 = EventsPage() self.widget1.nextPage.connect(self.nextPage) self.widget2 = MyWidget() self.addWidget(self.widget1) self.addWidget(self.widget2) def nextPage(self): self.setCurrentIndex(self.currentIndex() + 1) class EventsPage(QtGui.QWidget): nextPage = QtCore.pyqtSignal() def __init__(self, parent=None): QtGui.QWidget.__init__(self, parent) self.continueButton = QtGui.QPushButton('Continue') self.continueButton.clicked.connect(self.nextPage) So, basically, I'm connecting the continueButton clicked signal to the EventsPage nextPage signal, which I'm then connecting in Stacked to the nextPage method. I could just delve into the internals of EventsPage in Stacked and connect self.widget1.continueButton.clicked, but that seemed to completely defeat the purpose of signals and slots. So does this approach make sense, or is there a better way?

  • Eclipselink read complex object model in an ordered way

    - by Raven
    Hi, I need to read a complex model in an ordered way with eclipselink. The order is mandantory because it is a huge database and I want to have an output of a small portion of the database in a jface tableview. Trying to reorder it in the loading/quering thread takes too long and ordering it in the LabelProvider blocks the UI thread too much time, so I thought if Eclipselink could be used that way, that the database will order it, it might give me the performance I need. Unfortunately the object model can not be changed :-( The model is something like: @SuppressWarnings("serial") @Entity public class Thing implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; @OneToMany(cascade=CascadeType.ALL) @PrivateOwned private List<Property> properties = new ArrayList<Property>(); ... // getter and setter following here } public class Property implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; @OneToOne private Item item; private String value; ... // getter and setter following here } public class Item implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; .... // getter and setter following here } // Code end In the table view the y-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Thing m ORDER BY m.name ASC"); using the "name" attribute from the Thing objects as label. In the table view the x-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Item m ORDER BY m.name ASC"); using the "name" attribute from the Item objects as label. Each cell has the value Things.getProperties().get[x].getValue() Unfortunately the list "properties" is not ordered, so the combination of cell value and x-axis column number (x) is not necessarily correct. Therefore I need to order the list "properties" in the same way as I ordered the labeling of the x-axis. And exactly this is the thing I dont know how it is done. So querying for the Thing objects should return the list "properties" "ORDER BY name ASC" but of the "Item"s objects. My ideas are something like having a query with two JOINs. Joing Things with Property and with Item but somehow I was unable to get it to work yet. Thank you for your help and your ideas to solve this riddle.

  • Order by null/not null with ICriteria

    - by Kristoffer
    I'd like to sort my result like this: First I want all rows/objects where a column/property is not null, then all where the colmn/property is null. Then I want to sort by another column/property. How can I do this with ICriteria? Do I have to create my own Order class, or can it be done with existing code? ICriteria criteria = Session.CreateCriteria<MyClass>() .AddOrder(Order.Desc("NullableProperty")) // What do I do here? IProjection? Custom Order class? .AddOrder(Order.Asc("OtherProperty"));

  • How do I show a user's credit based on their session

    - by Jamie
    Hi all - I'm developing a simple LAMP app where users can credit their account using Paypal. I suspect this is a simple issue, but have spent quite a while experimenting to no avail and would appreciate any thoughts: System has a user management system working fine using sessions, but I can't get it to display the current user's credit. But I've been trying things along the lines of: $result = mysql_query(" SELECT * FROM users INNER JOIN account ON account.UserID=account.UserID ORDER BY account.accountID"); while($_SESSION['Username'] = $row['Username'] ) { echo $row['Username']; echo $row['Credit']; } I suspect the while statement is invalid, but I want it to echo username and credit where the current session username = the username stored in the database. Thanks so much for taking a look - very much appreciated.

  • I'm going to write 'Unit of Work', please help me find out all gimmicks

    - by o..o
    Hi everybody, I'm going to write my own DAL in C#. I decided to use 'Unit of Work' pattern (next mentioned as uow) with request as a scope and Identity map stored in HttpContext.Items. I have right now question about implementing of CRUD methods. How/where are they implemented? Are they implemented in every single business class (as in active records pattern) or are implemented somehow in uow class (if so, how)? I also suppose that I need to use as the scope not just the request, but also the db connection. But how? Should I open the connection a the start of the request and close it on uow disposing? Every advice is strongly appreciated, especially Your "real world" experiences. Thank you all :)

  • Collection.contains(Enum.Value) in HQL?

    - by Seth
    I'm a little confused about how to do something in HQL. So let's say I have a class Foo that I'm persisting in hibernate. It contains a set of enum values, like so: public class Foo { @CollectionOfElements private Set<Bar> barSet = new HashSet<Bar>(); //getters and setters here ... } and public enum Bar { A, B } Is there an HQL statement I can use to fetch only Foo instances who'se barSet containst Bar.B? List foos = session.createQuery("from Foo as foo " + "where foo.barSet.contains.Bar.B").list(); Or am I stuck fetching all Foo instances and filtering them out at the DAO level? List foos = session.createQuery("from Foo as foo").list(); List results = new ArrayList(); for(Foo f : foos) { if(f.barSet.contains(Bar.B)) results.add(f); } Thanks!

  • Using a priority queue in Java

    - by Bharat
    Forgive me if this is a tried question, but I'm having a little difficulty figuring it out. I currently have a class Node, and each 'node' is a square in a maze. I'm trying to implement the A* algorithm, so each of these nodes will have an f-cost (int) data member inside of it. I was wondering if there's a way that I can create a priority queue of these nodes, and set up the f-cost variable as the comparator? I've looked at examples online, but all I can find are String priority queues. Can I implement Comparator for the Node class? Would this allow me to access the data member stored inside it? Many Thanks!

  • DIV Overlaying DIV, links in backmost DIV non-accessible

    - by Shawn
    I have a photoshop image that is 500x600 that I am using as a background image for the first div. The second div sits over top of the first div and is populated with images. The z-index of the first div is set to 100. The effect is the photoshop image sits over top of all of the smaller images. The photoshop image is a letter with the inner-content of it set to be transparent and the small images create the filling. Each of the small images however is a link, but none of the links are accessible. How can I remedy that? I would post the code here, but I have absolutely no clue how to format it. I quite simply do not understand typing a backtick followed by the tab key and then a dollar sign. All that ends up is I type a backtick here followed by a dollar sign in the Tags section below.

  • UITableView not getting populated

    - by jayshree430
    Hi. I have a peculiar problem. I created a normal Objective c class called SampleTable. I then extended UITableView instead of NSObject. Then in the initWithFrame constructor i initialized the table. I also made a NSMutableArray object for the datasource. I also conformed UITableViewDelegate and UITableViewDatasource. I have overridden the necessary methods also. Now i made an object of this class in another class, and added the object as a subview. The tableView is getting drawn according to the CGRectMake() coordinates i gave to the initWithFrame constructor. But it is not getting populated with the data. I dnt know what the problem is . Can plz someone help me. SampleTable.h #import @interface SampleTable : UITableView { NSMutableArray *ItemArray; } @property (nonatomic,retain) NSMutableArray *ItemArray; -(NSMutableArray *) displayItemArray; @end SampleTable.m #import "SampleTable.h" @implementation SampleTable @synthesize ItemArray; -(id)initWithFrame:(CGRect)frm { [super initWithFrame:frm]; self.delegate=self; self.dataSource=self; [self reloadData]; return self; } -(NSMutableArray *) displayItemArray { if(ItemArray==nil) { ItemArray=[[NSMutableArray alloc] initWithObjects:@"1",@"2",@"3",@"4",@"5",nil]; } return ItemArray; } (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [ItemArray count]; } (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell= [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell==nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; [cell autorelease]; } NSString *temp=[self.ItemArray objectAtIndex:indexPath.row]; cell.textLabel.text = temp; return cell; } (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"didselect"); } -(void) dealloc { [ItemArray release]; [super dealloc]; } @end

  • confused about python decorators

    - by nbv4
    I have a class that has an output() method which returns a matplotlib Figure instance. I have a decorator I wrote that takes that fig instance and turns it into a Django response object. My decorator looks like this: class plot_svg(object): def __init__(self, view): self.view = view def __call__(self, *args, **kwargs): print args, kwargs fig = self.view(*args, **kwargs) canvas=FigureCanvas(fig) response=HttpResponse(content_type='image/svg+xml') canvas.print_svg(response) return response and this is how it was being used: def as_avg(self): return plot_svg(self.output)() The only reason I has it that way instead of using the "@" syntax is because when I do it with the "@": @plot_svg def as_svg(self): return self.output() I get this error: as_svg() takes exactly 1 argument (0 given) I'm trying to 'fix' this by putting it in the "@" syntax but I can't figure out how to get it working. I'm thinking it has something to do with self not getting passed where it's supposed to...

  • Java "constant string too long" compile error. Only happens using Ant, not when using Eclipse

    - by Allan
    I have a few really long strings in one class for initializing user information. When I compile in Eclipse, I don't get any errors or warnings, and the resulting .jar runs fine. Recently, I decided to create an ant build file to use. Whenever I compile the same class with ant, I get the "constant string too long" compile error. I've tried a number of ways to set the java compiler executable in ant to make sure that I'm using the exact same version as in Eclipse. I'd rather figure out how to get the same successful compile I get in Eclipse in Ant than try to rework the code to dynamically concatenate the strings.

  • How do I use logback-access in combination with Tomcat 5.5?

    - by mcduke
    I've got several Web apps running on a Tomcat 5.5 server, and I'm working on improving/updating the overall logging system used throughout the system. I already had some success with logback-classic. However, when I try to use logback-access (i.e. access the lbAccessStatus servlet), I get this exception: exception javax.servlet.ServletException: Wrapper cannot find servlet class ch.qos.logback.access.ViewStatusMessagesServlet or a class it depends on org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:433) ... root cause java.lang.ClassNotFoundException: ch.qos.logback.access.ViewStatusMessagesServlet org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1386) ... I have everything set up according to the docs: common/lib: logback-classic-0.9.15.jar logback-core-0.9.15.jar server/lib: logback-access-0.9.15.jar Moving around the libraries doesn't seem to help. logback-classic seems to work fine, it's just logback-access that causes problems.

  • Objective C message dispatch mechanism

    - by Dolphin
    I am just staring to play around with Objective C (writing toy iPhone apps) and I am curious about the underlying mechanism used to dispatch messages. I have a good understanding of how virtual functions in C++ are generally implemented and what the costs are relative to a static or non-virtual method call, but I don't have any background with Obj-C to know how messages are sent. Browsing around I found this loose benchmark and it mentions IMP cached messages being faster than virtual function calls, which are in turn faster than a standard message send. I am not trying to optimize anything, just get deeper understanding of how exactly the messages get dispatched. How are Obj-C messages dispatched? How do Instance Method Pointers get cached and can you (in general) tell by reading the code if a message will get cached? Are class methods essentially the same as a C function (or static class method in C++), or is there something more to them? I know some of these questions may be 'implementation dependent' but there is only one implementation that really counts.

  • Scala n00b: Critique my code

    - by Peter
    G'day everyone, I'm a Scala n00b (but am experienced with other languages) and am learning the language as I find time - very much enjoying it so far! Usually when learning a new language the first thing I do is implement Conway's Game of Life, since it's just complex enough to give a good sense of the language, but small enough in scope to be able to whip up in a couple of hours (most of which is spent wrestling with syntax). Anyhoo, having gone through this exercise with Scala I was hoping the Scala gurus out there might take a look at the code I've ended up with and provide feedback on it. I'm after anything - algorithmic improvements (particularly concurrent solutions!), stylistic improvements, alternative APIs or language constructs, disgust at the length of my function names - whatever feedback you've got, I'm keen to hear it! You should be able to run the following script via "scala GameOfLife.scala" - by default it will run a 20x20 board with a single glider on it - please feel free to experiment. // CONWAY'S GAME OF LIFE (SCALA) abstract class GameOfLifeBoard(val aliveCells : Set[Tuple2[Int, Int]]) { // Executes a "time tick" - returns a new board containing the next generation def tick : GameOfLifeBoard // Is the board empty? def empty : Boolean = aliveCells.size == 0 // Is the given cell alive? protected def alive(cell : Tuple2[Int, Int]) : Boolean = aliveCells contains cell // Is the given cell dead? protected def dead(cell : Tuple2[Int, Int]) : Boolean = !alive(cell) } class InfiniteGameOfLifeBoard(aliveCells : Set[Tuple2[Int, Int]]) extends GameOfLifeBoard(aliveCells) { // Executes a "time tick" - returns a new board containing the next generation override def tick : GameOfLifeBoard = new InfiniteGameOfLifeBoard(nextGeneration) // The next generation of this board protected def nextGeneration : Set[Tuple2[Int, Int]] = aliveCells flatMap neighbours filter shouldCellLiveInNextGeneration // Should the given cell should live in the next generation? protected def shouldCellLiveInNextGeneration(cell : Tuple2[Int, Int]) : Boolean = (alive(cell) && (numberOfAliveNeighbours(cell) == 2 || numberOfAliveNeighbours(cell) == 3)) || (dead(cell) && numberOfAliveNeighbours(cell) == 3) // The number of alive neighbours for the given cell protected def numberOfAliveNeighbours(cell : Tuple2[Int, Int]) : Int = aliveNeighbours(cell) size // Returns the alive neighbours for the given cell protected def aliveNeighbours(cell : Tuple2[Int, Int]) : Set[Tuple2[Int, Int]] = aliveCells intersect neighbours(cell) // Returns all neighbours (whether dead or alive) for the given cell protected def neighbours(cell : Tuple2[Int, Int]) : Set[Tuple2[Int, Int]] = Set((cell._1-1, cell._2-1), (cell._1, cell._2-1), (cell._1+1, cell._2-1), (cell._1-1, cell._2), (cell._1+1, cell._2), (cell._1-1, cell._2+1), (cell._1, cell._2+1), (cell._1+1, cell._2+1)) // Information on where the currently live cells are protected def xVals = aliveCells map { cell => cell._1 } protected def xMin = (xVals reduceLeft (_ min _)) - 1 protected def xMax = (xVals reduceLeft (_ max _)) + 1 protected def xRange = xMin until xMax + 1 protected def yVals = aliveCells map { cell => cell._2 } protected def yMin = (yVals reduceLeft (_ min _)) - 1 protected def yMax = (yVals reduceLeft (_ max _)) + 1 protected def yRange = yMin until yMax + 1 // Returns a simple graphical representation of this board override def toString : String = { var result = "" for (y <- yRange) { for (x <- xRange) { if (alive (x,y)) result += "# " else result += ".

  • Binding custom property in Entity Framework

    - by deverop
    I have an employee entity in my EF model. I then added a class to the project to add a custom property public partial class Employee { public string Name { get { return string.Format("{0} {1}", this.FirstName, this.LastName); } } } On a aspx form (inside a FormView), I want to bind a DropDownList to the employee collection: <asp:Label runat="server" AssociatedControlID="ddlManagerId" Text="ManagerId" /> <asp:DropDownList ID="ddlManagerId" runat="server" DataSourceID="edsManagerId" DataValueField="Id" DataTextField="Name" AppendDataBoundItems="true" SelectedValue='<%# Bind("ManagerId") %>'> <asp:ListItem Text="-- Select --" Value="0" /> </asp:DropDownList> <asp:EntityDataSource ID="edsManagerId" runat="server" ConnectionString="name=Entities" DefaultContainerName="Entities" EntitySetName="Employees" EntityTypeFilter="Employee" EnableFlattening="true"> </asp:EntityDataSource> Unfortunately, when I fire up the page, I get an error: DataBinding: 'System.Web.UI.WebControls.EntityDataSourceWrapper' does not contain a property with the name 'Name'. Any ideas what I'm doing wrong?

  • Exclude filter from certain url's

    - by Mads Mobæk
    I'm using a filter in web.xml to check if a user is logged in or not: <filter> <filter-name>LoginFilter</filter-name> <filter-class>com.mycompany.LoginFilter</filter-class> </filter> <filter-mapping> <filter-name>LoginFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> And this works like a charm until I have a stylesheet or image I want to exclude from this filter. I know one approach is to put everything that's protected inside /privateor similar, and then set the url-pattern to: <url-pattern>/private/*</url-pattern>. The downside to this is my URLs now looking like: http://www.mycompany.com/private/mypage instead of http://www.mycompany.com/mypage. Is there another solution to this problem, that let me keep my pretty-urls?

  • Comparing two List<MyClass> in C#

    - by Matt
    I have a class called MyClass This class inherits IEquatable and implements equals the way I need it to. (Meaning: when I compare two MyClass tyupe objects individually in code, it works) I then create two List: var ListA = new List<MyClass>(); var ListB = new List<MyClass>(); // Add distinct objects that are equal to one another to // ListA and ListB in such a way that they are not added in the same order. When I go to compare ListA and ListB, should I get true? ListA.Equals(ListB)==true; //???

  • XML deserialization problem (attribute with a namespace)

    - by Johnny
    hi, I'm trying to deserialize the following XML node (RDF actually) into a class. <rdf:Description rdf:about="http://d.opencalais.com/genericHasher-1/dae360d4-25f1-34a7-9c70-d5f7e4cfe175"> <rdf:type rdf:resource="http://s.opencalais.com/1/type/em/e/Country"/> <c:name>Egypt</c:name> </rdf:Description> [Serializable] [XmlRoot(Namespace = "http://www.w3.org/1999/02/22-rdf-syntax-ns#", ElementName = "Description")] public class BasicEntity { [XmlElement(Namespace = "http://s.opencalais.com/1/pred/", ElementName = "name")] public string Name { get; set; } [XmlAttribute("about", Namespace = "http://www.w3.org/1999/02/22-rdf-syntax-ns#")] public string Uri { get; set; } } The name element is parsed correctly but the about attribute isn't. What am I doing wrong?
