  • Hibernate - PropertyNotFoundException: Could not find a getter for ...

    - by Ben Noland
    I have a class that looks like the following: public class MyClass { private String dPart1; public String getDPart1() { return dPart1; } public void setDPart1(String dPart1) { this.dPart1 = dPart1; } } My hibernate mapping file maps the property as follows: <property name="dPart1" not-null="true"/> I get the following error: org.hibernate.PropertyNotFoundException: Could not find a getter for dPart1 in class com.mypackage.MyClass at org.hibernate.property.BasicPropertyAccessor.createGetter(BasicPropertyAccessor.java:282) at org.hibernate.property.BasicPropertyAccessor.getGetter(BasicPropertyAccessor.java:275) at org.hibernate.mapping.Property.getGetter(Property.java:272) at org.hibernate.tuple.entity.PojoEntityTuplizer.buildPropertyGetter(PojoEntityTuplizer.java:247) at org.hibernate.tuple.entity.AbstractEntityTuplizer.<init>(AbstractEntityTuplizer.java:125) at org.hibernate.tuple.entity.PojoEntityTuplizer.<init>(PojoEntityTuplizer.java:55) at org.hibernate.tuple.entity.EntityEntityModeToTuplizerMapping.<init>(EntityEntityModeToTuplizerMapping.java:56) at org.hibernate.tuple.entity.EntityMetamodel.<init>(EntityMetamodel.java:302) at org.hibernate.persister.entity.AbstractEntityPersister.<init>(AbstractEntityPersister.java:434) at It appears that hibernate doesn't like my capitalization. How should I fix this?

  • Edit Html.ActionLink output string

    - by Aaron Salazar
    I'm trying to output the following HTML using Html.ActionLink: <a href="/About" class="read-more">Read More<span class="arrow">?</span></a> I'm getting it done by doing an ActionLink, which outputs an tag and then manipulating the string. <%= Html.ActionLink("[[replace]]", "Index", "About", null, new { @class = "read-more" }).ToHtmlString().Replace("[[replace]]", "Read More" + "<span class='arrow'>?</span>")%></p> It'd be good if I could put HTML directly into the ActionLink but there doesn't seem to be a way based on my internet searches. Sure, it works but it seems like a hack. Is there a better way to accomplish this?

  • How to get the row and column of button clicked, in the grid event handler?

    - by younevertell
    Once the added button in grid is clicked, how to find which row and column the button is located in the grid event handler, like click event or some other events? Not the button click event handler #region Grid event handler setup myGrid.MouseEnter += new MouseEventHandler(myGrid_MouseEnter); myGrid.MouseLeave += new MouseEventHandler(myGrid_MouseLeave); myGrid.MouseDown += new MouseButtonEventHandler(myGrid_MouseDown); myGrid.MouseUp += new MouseButtonEventHandler(myGrid_MouseUp); #endregion Thanks I notice that Boyan has some solution for the button click event handler case http://stackoverflow.com/questions/363100/in-wpf-how-can-i-determine-what-column-row-in-a-grid-a-control-is In the Click event handler for the button you say: int row; Button btn = sender as Button; if (btn != null) { row = Grid.GetRow(btn); // And you have the row number... } else { // A nasty error occurred... }

  • Oracle: set timezone for column

    - by dbf
    Hi, I need to do migration date-timestamp with timezone similar to described here: http://stackoverflow.com/questions/1664627/migrating-oracle-date-columns-to-timestamp-with-timezone. But I need to make additional convertion (needed to work correctly with legacy apps): for all dates we need to change timezone to UTC and set time to 12:00 PM. So now dates are stored in local database (New York) timezone. I need to convert them this way 25/12/2009 09:12 AM (local timezone) in date column = 25/12/2009 12:00 PM UTC timestamp with local timezone column. Could you advice, how to set timezone for date value in Oracle (I found only suggestions how to convert from one timezone to another) (for example in Java there is setTimeZone method for Calendar objects). We want to make a convertion this way: rename old date column to NAME_BAK create new column timestamp with local timezone iterate over old column for not-null values set timezone to UTC, time to 12:00 PM drop old column after testing of this migration

  • adding tabs to tabcontrol from inside usercontrol

    - by Jakob
    How can I add tabs to a tabcontrol that exists in one usercontrol from another usercontrol that is contained within a tab itself?? Can I do it without passing in the tabcontrol as a parameter in the constructor, perhaps via some static global method? I've tried public static ObservableTabCollection FindCollectionFromUC(this DependencyObject depObject) { bool loop = true; var parent = (VisualTreeHelper.GetParent(depObject) as FrameworkElement); while (loop) { if (parent.GetType() is TabControl) { loop = false; return ((ObservableTabCollection)((TabControl)parent).ItemsSource); } } return null; } but this is just an infinite loop

  • NSNumberFormatter weirdness with NSNumberFormatterPercentStyle

    - by rein
    Hi, I need to parse some text in a UITextField and turn it into a percentage. Ideally, I'd like the user to either type something like 12 or 12% into the text field and have that be parsed into a number as a percentage. Here's what's weird. The number formatter seems to not like 12 and seems to divide 12% by 10000 instead of 100: NSNumberFormatter *formatter = [[[NSNumberFormatter alloc] init] autorelease]; [formatter setNumberStyle:NSNumberFormatterPercentStyle]; NSNumber *n1 = [formatter numberFromString:@"12"]; NSNumber *n2 = [formatter numberFromString:@"12%"]; NSLog(@"n1 = %@", n1); // n1 = (null) NSLog(@"n2 = %@", n2); // n2 = 0.0012 How do I get the formatter to return 0.12 as expected? EDIT: it seems to only happen if the formatter fails first. If the formatter does not fail it returns 0.12 as expected. Strange.

  • jQuery AJAX not redirecting?

    - by MidnightLightning
    I have a simple PHP page (for testing) that simply calls header("Location: http://www.example.com");exit;, which resides on the same server, in the same directory as another file with the following jQuery Javascript: $(document).ready(function() { jQuery.ajax({ type : 'GET', url : 'bounce.php', error : function(xhr, status, error) { console.log("ERROR: ", xhr, xhr.status, xhr.getAllResponseHeaders()); }, complete : function(xhr, status) { // Get headers of the response console.log("COMPLETE: ", xhr, xhr.status, xhr.getAllResponseHeaders()); } }); }); I was expecting (from several other StackOverflow responses) for the xhr.status to return "302", but instead the AJAX call is triggering the "error" event (and then the "complete" event), and xhr.status is returning 0 (zero), and .getAllResponseHeaders() is coming back null (in both the error, and complete functions). Firebug is showing the "302 Moved Temporarily", and the response headers. So why is this triggering the error event, and not passing along the proper 302 code, and headers? Is this something to do with the Same Origin since the bouncing script and the fetching script are both on the same server? Is this jQuery or Javascript's fault?

  • YouTube API Get all videos uploaded feed

    - by Paul
    Hi Guys, I can't seem to retrieve ALL videos from a particular channel on YouTube, despite the API giving example code that should perform just that. I'm using Java. http://gdata.youtube.com/feeds/api/users/GoogleDevelopers/uploads The above rss feed is the URL they suggest using along with the following sample code.. /*init the list*/ String feedUrl = "http://gdata.youtube.com/feeds/api/users/GoogleDevelopers/uploads"; VideoFeed videoFeeder = null; videoFeeder = serviceobject.getFeed(new URL(feedUrl), VideoFeed.class); Looping this with a for loop suggests 25 entries (as per the RSS). However - the actual number of videos uploaded is significantly larger. (662 at time of writing). My query is how on earth you retrieve everything with the API, not just a subset of the data. Any ideas on where I'm going wrong? Should I be using a different URL? http://www.youtube.com/GoogleDevelopers#g/a

  • ValueError with multi-table inheritance in Django Admin

  • Problem with Core Data - EXC_BAD_ACCESS

    - by BarrettJ
    I'm using the following code and I'm getting an EXC_BAD_ACCESS when trying to get the count of objects - anyone have any idea why? Oddly enough, the error only happens if the count should be one or greater, if there are no objects it seems to work fine (it outputs null). NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"TVShow" inManagedObjectContext:[self managedObjectContext]]; [fetchRequest setEntity:entity]; [fetchRequest includesPendingChanges]; //NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ID == %@", showId]; //[fetchRequest setPredicate:predicate]; NSError *error; NSLog(@"Generating Count"); NSUInteger count = [[self managedObjectContext] countForFetchRequest:fetchRequest error:&error]; if(count == NSNotFound) { NSLog(@"error"); } else { NSLog(@"%@", count); // EXC_BAD_ACCESS here } [fetchRequest release];

    Strange thing happening to me with the PreApplicationStartMethod Attribute. I did implement it in my latest project.

  • Custom view in ListView disappears while scrolling in Android

    - by troorl
    Hi. I wrote a simple custom view for rows in ListView. It works fine, but when I try to scroll the list, I see only white rows without content. And when scrolling is over, rows continue to show again. This is how I draw a custom view: @Override protected void onDraw(Canvas canvas) { if(poster != null) { canvas.drawBitmap(poster, padding, padding, paint); } canvas.drawText(title, 55 + padding, 16 + padding, paint); } Maybe I missed something? P.S. This is short screencast (400kb) http://dl.dropbox.com/u/190203/test.mpeg

  • Problem retrieving Hostaddress from Win32_TCPIPPrinterPort

    - by Anthony
    I'm running into an odd issue retrieving printer port addresses. When I get all the entries in Win32_TCPIPPrinterPort, the HostAddress field (which should have the IP address) is usually blank/null, only the port name has a value. To make it a bit stranger, if a particular port is not in use by any printer, THEN the HostAddress will have the the proper value. The C# code is simple, and results in something like this; IP_192.168.1.100, printerportxyz, richTextBox1.Clear(); ManagementObjectSearcher portSearcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_TCPIPPrinterPort"); foreach (ManagementObject port in portSearcher.Get()) { richTextBox1.AppendText( String.Format("Name: {0} HostAddress: {1}", port["Name"], port["HostAddress"]) ); } I also tried the same thing in WSH/VBS, and saw the same behavior.

  • Using key().id() on GAE Datastore and reverse geocoding

    - by Ivan Slaughter
    I have 6000 data of district, subdistrict. I need to represent this on dependent dropdown. The datamodel is for example; class Location(db.Model): location_name = db.StringProperty() location_parent = db.IntegerProperty() location_parent is reference to key() or id()? Still cannot decide which one is good. When i use key() as reference then using JSON to create jquery dependent drop down. My page loading/query and rendering time the dropdown is quite slow? Can i use key().id() as drop down option value to lighten up the page load? Any better solution for this parent/child reference for the drop down? For example: for the district record/entities the location-parent is null, for sub district record location_name will contain reference to parent district record. Other issue is to reverse geocoding the location to store or display geoPoint (lat,long)? Is google MAP API always find the exact lat,long of specific region boundaries or any error checking for the result?

  • Problem with Apache Commons Id UUID Version 1 generation

    - by Pekka Mattila
    My problem is to generate version 1 UUIDs. We use Jetty 6.x, Maven (to start Jetty among other things) and Apache Commons ID (to generate UUID version 1 from the current time). Apache Commons ID requires a configuration file that is told to the JVM, using a parameter, e.g. 'org.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml'. I checked the Apache Commons ID code and it tries to find the file from the classpath. Jetty's documentation states that WEB-INF/lib and WEB-INF/classes are in the classpath. The 'commons-id-uuid.xml' can be found from the deployed war file from the root of WEB-INF/classes directory but Jetty cannot load it: Message: java.lang.RuntimeException: java.lang.IllegalStateException: commons-id-uuid.xml loaded as system resource is null Jetty was started using the following command: mvn jetty:run -Dorg.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml Any idea what is going wrong? We just need to generate UUID version 1 identifiers. Any suggestions?

  • Shorten Zend Framework Route Definitions

    Hi! How can I shorten the definition of my custom routes in Zend Framework? I currently have this as definition: $route = new Zend_Controller_Router_Route( ":module/:id", array( "controller" => "index", "action" => "index" ), array("id" => "\d+") ); self::$frontController->getRouter()->addRoute('shortcutOne', $route); $route = new Zend_Controller_Router_Route( ":module/:controller/:id", array("action" => "index"), array("id" => "\d+") ); self::$frontController->getRouter()->addRoute('shortcutTwo', $route); $route = new Zend_Controller_Router_Route( ":module/:controller/:action/:id", null, array("id" => "\d+") ); self::$frontController->getRouter()->addRoute('shortcutThree', $route); Is there a way to better combine these rules? And what are your best practices in where to place these? I currently have them in my bootstrap class right after the Front Controller initialization.
