  • Using java classes in Grails

    - by RN
    I have a Java\Spring\Hibernate application - complete with domain classes which are basically Hibernate POJOs There is a piece of functionality that I think can be written well in Grails. I wish to reuse the domain classes that I have created in the main Java app What is the best way to do so ? Should I write new domain classes extending the Java classes ? this sounds tacky Or Can I 'generate' controllers off the Java domain classes ? What are the best practices around reusing Java domain objects in Grails\Groovy I am sure there must be others writing some pieces in grails\groovy If you know about a tutorial which talks about such an integration- that would be awesome !!! PS: I am quite a newbie in grails-groovy so may be missing the obvious. Thanks !!!

  • Overriding SQLMembershipProvider

    - by vikp
    Is there built in methods into .net framework to do the following: Get role GUID from user name/user GUID Get role name from role GUID So far I have been sending queries to the asp_roles and asp_users tables to obtain that information and I'm wondering if there is a nicer way of doing this? I have the following methods that I store in the ASPUtilities class: getRoleGUID(guid userGuid) { LINQ joins } getRoleGuid(string userName) { LINQ joins } getRoleName(guid roleGuid) { LINQ joins } EDIT: I have just looked into extending SQLMembershipProvider examples. Few examples completely override the SQLMembershipProvider, but I think what I'm interested is just adding few extra methods to deal with the roles by using LINQ. Is this feasible?

  • JLabel with separate text and icon background colours

    - by emeraldjava
    Hey, I have a simple Jlabel element with text and icon setting the background changes the full label colour. I want to be able to only render the background colour on the text section of the label, ie - to have separate backgrounds/foregrounds for the icon and text. Selecting/deselecting the label will flip the colour behind the icon and text. Is this possible to do this by just extending JLabel, and if so which methods should i be looking to customise? My alternative idea is to create a panel with two separate label elements, one with an icon the other with text. It seems a bit messy, and before i start i'm wondering is there a smarter way of achieving this with Swing.

  • Shorthand for nested null checking C#

    - by Myster
    As far as I know there is not a significantly more elegant way to write the following.... string src; if((ParentContent!= null) &&(ParentContent.Image("thumbnail") != null) &&(ParentContent.Image("thumbnail").Property("src") != null)) src = ParentContent.Image("thumbnail").Property("src").Value Do you think there should be a C# language feature to make this shorter? And if so, what should it look like? for example, something like extending the ?? operator string src = ParentContent??.Image("thumbnail")??.Property("width")??.Value; Apologies for the rather contrived example, and my over-simplified solution.

  • Get "As low as" price for bundle product in Magento

    - by dardub
    I'm trying to display a list of bundled products using my custom template. I'm not able to display the dynamic price of the bundle product. Previously for simple products I used: $product->getPrice(); which worked, but it just displays $0.00 for bundle items. looking at ../catalog/products/list.phtml I tried $this->$getPriceHtml($product, true); after extending my block to Mage_Catalog_Block_Product_Abstract I got simple products working again, but bundle products still show $0.00 Is there another way to display the as low as price for dynamic bundle prices? I cleared cache and reindexed and all that good stuff. The price shows up correctly under the default category list, just not under my custom page.

  • Android: Registering ContextMenu for a Custom ListAdapter

    - by primal
    Hi, I made a custom list adapter extending the Base adapter. Each item in the list has an imagebutton, 2 textviews and a button. I tried to add the context menu to the list so as to display some options for an item in the list. registerForContextMenu(getListView()); I used a MenuInflater object to inflate the context menu xml file. But on clicking the items in the list nothing shows up or the usual highlighting of the item of list on click isn't shown. Is it that the context menu doesn't work for custom list views? Any help would be much appreciated. Regards, Primal

  • C# thread with multiple parameters

    - by Lucas B
    Does anyone know how to pass multiple parameters into a Thread.Start routine? I thought of extending the class, but the C# Thread class is sealed. Here is what I think the code would look like: ... Thread standardTCPServerThread = new Thread(startSocketServerAsThread); standardServerThread.Start( orchestrator, initializeMemberBalance, arg, 60000); ... } static void startSocketServerAsThread(ServiceOrchestrator orchestrator, List<int> memberBalances, string arg, int port) { startSocketServer(orchestrator, memberBalances, arg, port); } Thank you in advance. BTW, I start a number of threads with different orchestrators, balances and ports. Please consider thread safety also.

  • Absolute path of a file object

    - by Morgoth
    This has been discussed on StackOverflow before - I am trying to find a good way to find the absolute path of a file object, but I need it to be robust to os.chdir(), so cannot use f = file('test') os.path.abspath(f.name) Instead, I was wondering whether the following is a good solution - basically extending the file class so that on opening, the absolute path of the file is saved: class File(file): def __init__(self, filename, *args, **kwargs): self.abspath = os.path.abspath(filename) file.__init__(self, filename, *args, **kwargs) Then one can do f = File('test','rb') os.chdir('some_directory') f.abspath # absolute path can be accessed like this Are there any risks with doing this?

  • How to convert a plist file from mac os project to iphone project?

    - by Tom Pace
    I am developing an app for the iPhone OS devices, and am using a third-party engine which is not well documented but I've made great progress with it anyway. The problem: The engine's developer strongly urges extending from the existing template projects bundled with the engine, but the engine's plist files are Mac OSX project plist files. This is an iPhone engine, and so I cannot understand why the plist file is structured to take keys for Mac OS apps, but that's how it is. I did a FileMerge comparison to ensure there was nothing within the file itself that defined its use for one OS or the other, so I guess it's defined somewhere in the project settings.

  • Java static and thread safety or what to do

    - by Parhs
    I am extending a library to do some work for me. Here is the code: public static synchronized String decompile(String source, int flags,UintMap properties,Map<String,String> namesMap) { Decompiler.namesMap=namesMap; String decompiled=decompile(source,flags,properties); Decompiler.namesMap=null; return decompiled; } The problem is that namesMap is static variable. Is that thread safe or not? Because if this code runs concurently namesMap variable may change. What can I do for this?

  • How do I determine if a JDialog has children?

    - by Morinar
    I've got a custom window class that is a couple levels down extending a JDialog. We have windows that we create and sometimes we create new windows as children of existing windows using the constructor that takes a parent argument. I need to put some code somewhere in our custom class that does something different depending on whether not the window has children. I know of getParent(), etc, and I can see that I can loop through the components of the window, but for the life of me, I can't seem to figure out how to determine whether or not my current window has any child windows. Is there a way to do this? Any help is, as always, much appreciated.

  • Is it acceptible to expect mentoring to replace many years experience?

    - by Mantorok
    Hi all Just a quick question Here's my situation: I've been maintaining, extending and creating websites against a CMS for the last 18 months In that time I've learnt a LOT more about ASP.Net, javascript, and of course the quirks of the CMS we are using My manager wants to get others involved, and I'm expected to mentor another programmer whilst they work on production code Now, I've got no problem mentoring someone and it would be great for me to not be the only one with the skillset. But what I HAVE got a problem with is mentoring someone within an agreed timescale of the piece of work (10 days in this case) AND expected to deliver the product to the same standard. I guess what I'm getting at is: 18 months experience != a few days mentoring, not to mention the level of C#/.Net/ASP.Net/Javascript required may also not be up to scratch. Am I right to think this is a little, wrong?

  • Alternative to COM blind aggregation in .NET for class with private interface

    - by Philip
    When extending a COM class in unmanaged C++ where the original class has private interfaces, one way to do this is through the concept of blind aggregation. The idea is that any interface not explicitly implemented on the outer aggregating class is 'blindly' forwarded to the inner aggregated class. Now .NET as far as I can figure out does not support COM aggregation natively. A somewhat tedious workaround is to create a .NET class where you implement all the required COM interfaces directly on the .NET class and simply forward to an instance of the actual COM class for any methods you don't want to override. The problem I have is when the original COM object has one or more private interfaces, i.e. undocumented interfaces that are nonetheless used by some consumers of the original class. Using blind aggregation in unmanaged C++ this is a non-issue as the calls to the private interfaces are automatically forwarded to the original class, however I can't find any way of doing the same thing in .NET. Are there any other ways of accomplishing this with .NET?

  • How to edit localized forms all at one time in Visual Studio

    - by SoMoS
    Hello, I have several forms that are localized to multiple languages. If I do a change on one form (for example, changing the size of a textbox) the change is done only on the localized version of the Form that I have currently selected. Is there a way of extending the change I've done the different localized versions of the same Form to avoid having to go one by one doing the same change by hand? Thanks in advance for your help. EDIT: I'm talking about different forms when the real thign is that you have one form and several resources. The point is that at the end is just like if you have different forms for each locale because the form is built with the data from the resource. The problem is still the same because the edits done on the form are stored at one resource file and I have to put by hand those edits in all the resources.

  • How to make Date locale-independent? (GMT timezone newbie question)

    - by folone
    I have a db, that stores dates in OleDateTime format, in GMT timezone. I've implemented a class, extending Date in java to represent that in classic date format. But my class is locale-dependent (I'm in GMT+2). Therefore, it converts the date in the db as date - 2 hours. How do I make it convert the date correctly? I want my class to be locale-independent, always using GMT timezone. Actually, the question is: class MyOleDateTime extends Date { static { Locale.setDefault(WhatGoesHere?) } // ... some constructors // ... some methods }

  • OpenDACS .Net Framework

    - by Goober
    Scenario As some of you may have heard, OpenDACS is an open source data-access control system for enforcing data usage permissions. DACS comes integrated with the Reuters platform but you can use OpenDACS for extending third-party software. I'm using IE6, I can't embed these links properly. http://thomsonreuters.com/products_services/financial/financial_products/real-time/data_access_control_system https://customers.reuters.com/developer/Kits/OpenDACS/opendacs.aspx Question Has anyone used OpenDACS at all? I'm quite interested in it but I have no idea where to start. Ideally some examples would be fantastic, or a startup guide. Thoughts I use C# heavily and am looking to extend a C# application with DACS. I understand that there is currently no C# API, however I've heard that the SFC-COM Edition can used with the .Net/COM interoperability layer Help greatly appreciated. Cheers.

  • lwjgl 101: How can I write applets?

    - by Vuntic
    I have a working app in lwjgl. It doesn't do much yet; I've just started, but it does compile and run like it's supposed to. I want to make it into an applet. I've followed the guide here, and I have an applet that runs nicely and displays text and such in the applet area and can access the functions of lwjgl (like Sys.alert), but I can't figure out how to get opengl to actually render. I've tried extending an AWTGLCanvas and calling this.add(myAWTGLCanvas), where this is the Applet that I'm using, but... nothing. The initGL() and paintGL() methods never get called. I wonder if I'm supposed to be doing something with Display, but that's not for applets, right? Help? Also: This counts as a "beginner" question, right? Edit: Here's a simplified version of what I have.

  • Android Class which extends Dialog, how to clear TextViews before it is displayed

    - by wuntee
    I have a class that extends android.app.Dialog, the layout is done in an xml file, and the setup (button listeners, etc) is done on the onCreate method. My problem is that whenever the dialog is displayed, then dismissed, and displayed again, the Editable TextViews are still populated with the information that was displayed previously. What is the common way to clear these text fields? Remember - this is a separate class that extends Dialog - so there is no 'onDialogCreate' like Activity has. Or, perhaps I am extending the wrong class? There is just a lot of processing being done, and do not want to have all the code in the main Activity. I would like it to be in a separate Class. I tried to extend AlertDialog, but it does not create the border like Dialog does. Any help would be great. The dialog is shown via the Activity: protected Dialog onCreateDialog(int id) { switch(id){ case DIALOG_NEW_SAFE: return(new NewSafeDialog(this)); default: return(null); } }

  • Best practice Unit testing abstract classes?

    - by Paul Whelan
    Hello I was wondering what the best practice is for unit testing abstract classes and classes that extend abstract classes. Should I test the abstract class by extending it and stubbing out the abstract methods and then test all the concrete methods? Then only test the methods I override and the abstract methods in the unit tests for objects that extend my abstract class. Should I have an abstract test case that can be used to test the methods of the abstract class and extend this class in my test case for objects that extend the abstract class? EDIT: My abstract class has some concrete methods. I would be interested to see what people are using. Thanks Paul

  • making certain cells of an ExtJS GridPanel un-editable

    - by synchronicity
    I currently have a GridPanel with the Ext.ux.RowEditor plugin. Four fields exist in the row editor: port, ip address, subnet and DHCP. If the DHCP field (checkbox) of the selected row is checked, I need to make the other three fields un-editable. I've been trying to perform this code when the beforeedit event is triggered, but to no avail... I've only found ways to make the entire column un-editable. My code so far: this.rowEditor.on({ scope: this, beforeedit: this.checkIfEditable }); checkIfEditable:function(rowEditor, rowIndex) { if(this.getStore().getAt(rowIndex).get('dhcp')) { // this function makes the entire column un-editable: this.getColumnModel().setEditable(2, false); // I want to make only the other three fields of the current row // uneditable. } } Please let me know if any clarification is needed. Any help potentially extending RowEditor to accomplish the target functionality would be greatly appreciated as well!

  • Is there an "extended" UIHint attribute to apply CSS styles for DisplayFor - EditorFor templates?

    - by AJ
    Intro: After reading Brad Wilson Metadata series and searching unsuccesfully on google, I was wondering: Question: Has any OS project / code been created that allows you to tag CSS styles in the Meta information, for example in my (buddy) Model, I want to be able to decorate a property with multiple CSS styles (a single style you can fake with UIHint, I want to set many possible styles - and be able to "cross-utilise") eg. public class MyModel { [DisplayCssHint("h5")] [DisplayCssHint("color:#777;")] [EditorCssHint(".myCoolTextClass")] [EditorCssHint(".myOtherCoolTextClass")] public string Title{ get;set; } [DisplayCssHint(".normaltext")] [EditorCssHint(".myCoolTextClass")] [EditorCssHint(".myOtherCoolTextClass")] public string Message {get;set;} } Thoughts: I know that this does not seem like a logical place to put styling information, however as it is metadata and is discriptive... besides it would be nice to do this while prototyping - (especially being able to apply class styles and extending it further - to generate .Less files would really be cool! more to the point I would hate to write it, if its already been done ;). Any links/pointers/idea's would be appreciated. Thanks,

  • Java: using endpoint to publish webservice to tomcat server

    - by Will
    hi all, i am creating a simple SOAP web service. i am to ensure that it runs on a tomcat web service. im trying to implement this with JAX-WS (see code) my question is: does the Endpoint.publish use the tomcat server to host this or is it a mini glassfish kind of server? should i be extending UnicastRemoveObject or something similiar instead? ideally it would be able to be packaged into a .WAR and dropped in the directory and just work. It doesn't seem to work with my installed tomcat server as is because it says the port is already in use. I'm using Ubuntu karmic with the tomcat6 package installed, it could also be my user doesnt have permissions to publish to the running tomcat on 8080 i hope this question is clear enough sample code: @WebService public class UserAttributes { public static void main(String[] args) { UserAttributes instance = new UserAttributes(); Endpoint.publish("http://localhost:8082/WebServices/userattributes", instance); } public string Hello() { return "Hello World"; } }

  • Accessing constructor from abstract base class with reflection

    - by craesh
    Hi! I'm playing around with Java's Reflection. I have an abstract class Base with a constructor. abstract class Base { public Base( String foo ) { // do some magic } } I have some further classes extending Base. They don't contain much logic. I want to instantiate them with Base's constructor, without having to write some proxy contructors in those derived classes. And of course, I want to instantiate those derived classes with Reflection. Say: Class cls = SomeDerivedClass.class; Constructor constr; constr = cls.getConstructor( new Class[] { String.class } ); // will return null Class clsBase = Base.class; constr = clsBase.getConstructor( new Class[] { String.class } ); // ok Base obj = (Base) constr.newInstance( new Object[] { "foo" } ); // will throw InstantiationException because it belongs to an abstract class Any ideas, how I can instantiate a derived class with Base's constructor? Or must I declare those dumb proxy constructors?
