• GWT and java.io.Serializable

  - by Ethan Leroy

  Hello, In my GWT app I have the following model class: import com.google.gwt.user.client.rpc.IsSerializable; public class TestEntity implements IsSerializable { public String testString; } This class implements the GWT custom IsSerializable marker interface - which I really don't like, because I use my model classes not only for GWT. So I prefer java.io.Serializable. But if I modify the class to implement Serializable instead of IsSerializable, the GWT RPC mechanism doesn't work anymore. I don't get an error on the server side, but on the client AsyncCallback.onFailure is invoked. I am using... GWT 1.7.0. Spring 2.5.6.SEC01 Spring and GWT are configured as described here.

• Figuring if a link is clicked on a webView - iPhone

  - by Uygar

  Hi, I am using a custom webview to show a tabbar when user touches on the webview. But when I clicked on a link in a webview, tabbar is shown for a little time and then page loads. I am using this custom webview to detect touch: http://github.com/psychs/iphone-samples/blob/b772b963f2acf18d478b41b44555992fcd8d4f31/WebViewTappingHack/Classes/PSWebView.m Can I detect if a link clicked or not? Because a link stands on the webview, webview detects the touch and also it loads the page... I want to prevent it. Thanks in advance.

• Google App Engine (python): TemplateSyntaxError: 'for' statements with five words should end in 'rev

  - by Phil

  This is using the web app framework, not Django. The following template code is giving me an TemplateSyntaxError: 'for' statements with five words should end in 'reversed' error when I try to render a dictionary. I don't understand what's causing this error. Could somebody shed some light on it for me? {% for code, name in charts.items %} <option value="{{code}}">{{name}}</option> {% endfor %} I'm rendering it using the following: class GenerateChart(basewebview): def get(self): values = {"datepicker":True} values["charts"] = {"p3": "3D Pie Chart", "p": "Segmented Pied Chart"} self.render_page("generatechart.html", values) class basewebview(webapp.RequestHandler): ''' Base class for all webapp.RequestHandler type classes ''' def render_page(self, filename, template_values=dict()): filename = "%s/%s" % (_template_dir, filename) path = os.path.join(os.path.dirname(__file__), filename) self.response.out.write(template.render(path, template_values))

• Please help me decide how to figure out XNA's ContentPipeline

  - by DDTmanSP

  I have read this link : http://msdn.microsoft.com/en-us/library/bb464156.aspx They said : "... the XNA Framework Redistributable file does not contain the Content Pipeline Build Runtime. Building content at run time is supported only when XNA Game Studio has been installed on the Windows-based development computer." Actually, before I know of that, I have already used a lot of content pipeline to help me read out my game's assets. And because of that, I am now very headache to confront the publish's problem "The application requires that the assemblies Microsoft.Xna.Framework.Content.Pipeline 3.1.0.0 be installed ....." So I would like to find some ways that can help me solve this without convertion of my pipelines. So that I don't need to rewrite it all in new classes that manually load assets for me. Regard, DDTmanSP

• Interfaces with hibernate annotations

  - by molleman

  Hello i am wondering how i would be able to annotate an interface @Entity @Table(name = "FOLDER_TABLE") public class Folder implements Serializable, Hierarchy { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "folder_id", updatable = false, nullable = false) private int fId; @Column(name = "folder_name") private String folderName; @OneToMany(cascade = CascadeType.ALL) @JoinTable(name = "FOLDER_JOIN_FILE_INFORMATION_TABLE", joinColumns = { @JoinColumn(name = "folder_id") }, inverseJoinColumns = { @JoinColumn(name = "file_information_id") }) private List< Hierarchy > fileInformation = new ArrayList< Hierarchy >(); above and below are 2 classes that implement an interface called Hierarchy, the folder class has a list of Hierarchyies being a folder or a fileinformation class @Entity @Table(name = "FILE_INFORMATION_TABLE") public class FileInformation implements Serializable, Hierarchy { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "file_information_id", updatable = false, nullable = false) private int ieId; @Column (name = "location") private String location; i have serached the web for someway to annotate or a workaround but i cannot map the interface which is simply this public interface Hierarchy { } i get a mapping exeception on the List of hierarchyies with a folder but i dont know how to map the class correctly

• NHibernate 2.1.2 in medium trust.

  - by John

  I'm trying to configure nhibernate 2.1.2 to run in medium trust, without any luck. I have tried follwing the suggestions to run in medium trust and pre-generating the proxies. I then tried to remove all references to lazy loading setting the default-lazy="false" on all classes and bags. However this threw an exception asking me to configure the proxyfactory.factory_class None of these methds worked as they kept throwing generic security exceptions or throwing easying that libraries do not allow AllowPartiallyTrustedCallers. Am I using the wrong version of NHibernate if I want to run in medium trust? Is there a specific set of binaries, or source, which I should be using.

• How to get vm arguments from inside of java application?

  - by Dmitriy Matveev

  Hello, I need to check if some option which can be passed to JVM is explicitly set or is it have default value. To be more specific: I need to create one specific thread with higher native stack size than the default one, but in case then user want to take care of such things by himself by specifying -Xss option I want to create all threads with default stack size (which will be specified by user in -Xss option). I've checked classes like java.lang.System and java.lang.Runtime, but these aren't giving me information about vmargs. Is there any way to get information I need?

• Silverlight using WCF Ria with POCOS gives edit operation error

  - by JD

  Hi, I have converted an Entity framework project to use POCO objects by removing the entity data model and the domain service and meta data classes. My silverlight project works as it is showing a datagrid of Employee objects. I have not added a DataForm and when I modify the "name" property of one of my Employee objects, I get the error: This EntitySet of type 'TestEmployeesApp.Web.Employee' does not support the 'Edit' operation. The error occurs on validatingProperty() on the class Entity on the client side. I checked the metadata on the server side, and all my properties have the attribute Editable(true). I am using Silverlight 3 with VS2008. JD

• Generating new sources via Maven plugin after compile phase

  - by japher

  I have a Maven project within which I need execute two code generation steps. One generates some Java types, then the second depends on those Java types to generate some more code. Is there a way to have both of these steps happening during my build? At the moment my steps are: execute first code generation plugin (during generate-sources) add directory of generated types to build path execute second code generation plugin (during compile) However my problem is that anything generated by the second code generation plugin will not be compiled (because the compile phase has finished). If I attach the second code generation plugin to an earlier phase, it fails because it needs the classes from the first code generation plugin to be present on the classpath. I know I could split this into two modules with one dependent on the other, but I was wondering if this could be achieved in one pom. It seems like a need a way to invoke compile again after the normal compile phase is complete. Any ideas?

• JavaScript Multi-Dimensional Arrays

  This wasn't the question I was going to ask but I have unexpectedly run aground with JavaScript arrays. I come from a PHP background and after looking at a few websites I am none the wiser. I am trying to create a multi-dimensional array. var photos = new Array; var a = 0; $("#photos img").each(function(i) { photos[a]["url"] = this.src; photos[a]["caption"] = this.alt; photos[a]["background"] = this.css('background-color'); a++; }); Error message: photos[a] is undefined. How do I do this? Thanks.

• ASP.NET MVC 2 RC2 Model Binding with NVARCHAR NOT NULL column

  - by Gary McGill

  I have a database column defined as NVARCHAR(1000) NOT NULL DEFAULT(N'') - in other words, a non-nullable text column with a default value of blank. I have a model class generated by the Linq-to-SQL Classes designer, which correctly identifies the property as not nullable. I have a TextAreaFor in my view for that property. I'm using UpdateModel in my controller to fetch the value from the form and populate the model object. If I view the web page and leave the text area blank, UpdateModel insists on setting the property to NULL instead of empty string. (Even if I set the value to blank in code prior to calling UpdateModel, it still overwrites that with NULL). Which, of course, causes the subsequent database update to fail. I could check all such properties for NULL after calling UpdateModel, but that seems ridiculous - surely there must be a better way? Please don't tell me I need a custom model binder for such a simple scenario...!

• luntbuild + maven + findbugs = OutOfMemoryException

  - by Johannes

  Hi, I've been trying to get Luntbuild to generate and publish a project site for our project including a Findbugs report. All other reports (Cobertura, Surefire, JavaDoc, Dashboard) work fine, but Findbugs bails out with an OutOfMemoryException. Excluding findbugs from report generation fixes the build --- although obviously without a Findbugs report. The funny thing is that I first encountered this problem locally and solved it by setting MAVEN_OPTS=-Xmx512m. This does not seem to be enough in Luntbuild, however: setting that exact same option as an environment variable of my builder doesn't make a difference. I've found a couple of posts on the 'net stating you should also add -XX:MaxPermSize=512m to MAVEN_OPTS and/or pass -Dmaven.findbugs.jvmargs=-Xmx512m to mvn.bat. None of these (or their combination) seem to help though so any hints would be greatly appreciated! Cheers, Johannes Relevant information: Luntbuild is 1.5.6, Maven is 2.1.0, findbugs-maven-plugin is 2.0.1.

• horizontal scrolling only!

  - by Crippletoe

  Hi all i have a that contains a HORIZONTAL menu. the menu consists of an unordered list. i would like the div to get a horizontal scroller whenever the menu exceeds the width of the <div>. i tried using these CSS definitions for my <div>: position: absolute; width: 380px; overflow: auto; overflow-y: hidden; height: 30px; but than realized that since the menu is LIST, the different list items break the line whenever they reach the width of the <div> and move on to the next line, thus the browser doesnt see the need for a horizontal scroller (it doesnt display a vertical one as well because of the overflow-y: hidden; line) any ideas how i can create a 1 line horizontal menu which will scroll horizontally only? thank you all so much.

• JAutodoc for Eclipse

  Hi, I'm trying to generate javadoc with JAutodoc 1.7 for Eclipse 3.5. I've sucessfully created templates for files, classes, methods. However, on parameters and exceptions I get the default @param and @throws tags generated even if I change the template in preferences/JAutodoc/templates/parameters. This is incompatible with the coding standards they have given us. Any help? Btw, I tried to use the default eclipse comment template but I couldn't find any enclosing_method_arguments variable in my version. Any ideas why that might be?

• How to show a progress report to the user in Google Apps Script?

  - by Jose M Vidal

  I have a simple script that will send out a bunch of emails but these take time to send and I want to show the user a scrolling window with the emails addresses as they are sent (or, a progress bar would be good too). I believe this is possible with the new User Interface Classes, but I can't get it to work. The documentation is kinda sparse. Specifically, the problem is that the GUI window that pops up appears blank until all the emails have been sent (the script ends) and then the text appears. This happens even if I call show(myapp) after every time I update the Label.

  I've developed a website in html/css and it works perfectly fine. Now I'm working with the coder, integrating this to a .NET framework, changing the website to .apsx instead of html, but during the build of the website, the only error that is marked is the load of Cufon , it simply can't load and the structure and syntax of all the commands are the same I used with the html site that actually works. There are no path problems so far. What do you guys think would be this problem ? Thank you for your kind help.

• Scrollable div on iPhone without using 2 fingers?

  - by Brad Parks

  Hi there; I've got a UIWebView embedded in my iPhone app, and I'd like to keep a locked header and footer DIV on the page at all times, with a scrollable center DIV. I know that I could do this using a header/footer that are UIView controls, but I want the header and footer to be HTML divs, as a pure HTML/JS/CSS solution will be easier to port to Android/PalmPre/AdobeAir, which is going to be on my todo list relatively soon. I can do this using techniques like the one mentioned here: http://defunc.com/blog/?p=94 But this requires that the user use 2 fingers to scroll the div, which is not satisfactory to me... Any suggestions on how to do this? Thanks, Brad

• mvc presentation model best-practices

  - by Andrew Florko

  Hello, everybody How do you usually convert business objects to presentation? For example: Business object Person { Id, FirstName, LastName, Patronymic ... } should be presented as "LastName F. P. " in html layout. We use Presentation classes hierarchy to represent data ready for output from Business model. Questions: Will you keep presentation model completely separated from Business Model. For example, can strong-typed views (MVC ASP.NET) aggregate formatted business data as well as raw business objects (that leads toward <%=Html.Encode(PersonHelper.ToShort(Model.Person))% html layout injections) What architecture layer do you choose for conversion (mvc controllers that formats business data from business layer, for instance). Thank you in advance

• Breaking changes in .NET 4.0

  - by Andrei Taptunov

  There is a lot of information about new features and classes in new 4.0 however there are also changes that may affect esixting applications, for example Timespan now implements IFormattable and old string.Format() with invalid options will throw exception instead of calling simple ToString(). However, CLR team provides a nice feature to enable behaviour from previous version with configuration setting - TimeSpan_LegacyFormatMode . CLR Inside Out Access to events inside the class where they are declared using += or -= will lead to call add/remove generated accessors that return void. Some code wan't even compile in 4.0. Chris Burrows Blog CAS is deprecated and to enable it one still need to use special setting in configuration - NetFx40_LegacySecurityPolicy So I wonder what are other changes and is it possible to find at least preliminary list of changes that will or may break existing functionality with release of .NET 4.0 ?

• Bullet Physics, when to choose which DynamicsWorld?

  - by Sqeaky

  I have a few general questions about the bullet physics library. Here is my current understanding in a nutshell: btDiscreteDynamicsWorld - Simplest physics world, only handles rigid bodies, maybe it has better performance. btSoftRigidDynamicsWorld - The only physics world that can work with large jello moulds btContinuousDynamicsWorld - If you have really fast objects this will prevent them from prenetrating each other or flying through each other, but is otherwise like a btDiscreteDynamicsWorld. Is my understanding of the btDiscreetDynamicsWorld, btContinuousDynamicsWorld and btSoftRigidDynamicsWorld classes in terms of functionality, purpose, and performance correct? Why does the user manual recommend the btDiscreteDynamicsWorld class? btSoftRigidDynamicsWorld appears to be the only world that can handle soft bodies, so what if we wanted Continuous Physics integration and Soft bodies? How fast is fast enough to consider using a btContinuousDynamicsWorld, and what are the drawbacks of using one? Edit: My Buddy Mako also posted this question on The Bullet forums: http://www.bulletphysics.org/Bullet/phpBB3/viewtopic.php?f=9&t=4863

• Does business logic belong in the service layer?

  - by antony.trupe

  I've got a set of classes, namely, a data transfer object, a service implementation object, and a data access object. I currently have business logic in the service implementation object; it uses the dao to get data to populate the dto that is shipped back to the client/gui code. The issue is that I can't create a lightweight junit test of the service implementtion object(it's a servlet); I think the business logic should be elsewhere, but the only thing I can think of is putting business logic in the dao or in yet another layer that goes between the dao and the service implementation. Are there other options, or am I thinking about this the wrong way? It's a GWT/App Engine project.

• How to display image in grails GSP?

  - by Walter

  I'm still learning Grails and seem to have hit a stumbling block. Here are the 2 domain classes: class Photo { byte[] file static belongsTo = Profile } class Profile { String fullName Set photos static hasMany = [photos:Photo] } The relevant controller snippet: class PhotoController { ..... def viewImage = { def photo = Photo.get( params.id ) byte[] image = photo.file response.outputStream << image } ...... } Finally the GSP snippet: <img class="Photo" src="${createLink(controller:'photo', action:'viewImage', id:'profileInstance.photos.get(1).id')}" /> Now how do I access the photo so that it will be shown on the GSP? I'm pretty sure that profileInstance.photos.get(1).id is not correct. Thanks!!

• Controllling Drupal's active/active-trail with duplicate menu items

  - by Mark

  I'm developing a site that requires some duplication of links within the menu: Section A -- Introduction -- Testimonials Section B -- Introduction -- Testimonials Testimonials -- Section A -- Section B So 'Section A Testimonials' and 'Testimonials Section A' point to the same node. But regardless of which menu link people use, I want the person to be in Section A. The problem is that D6 doesn't like duplicate menu items, and it assigns the active and active-trail classes rather unpredictably. So my thought was to create a placeholder node for each item in the Testimonials menu, and then set the URL to something like "testimonials/redirect/section-a", and then use mod_rewrite to redirect over to "section-a/testimonials". With this solution, I will have no duplicate paths in the menu. I'm just hoping this doesn't somehow hurt my SEO. Does anyone know a better solution?
