• How to import a WCF web service using a Java client

  - by JRP

  I have a WCF web service using wsHttpBinding that I am consuming from a Java client. I generated code from the WSDL using wsimport. The java client appears to be creating the service fine but when I call a method on the service the client just spins. MyService s = new MyService(); IMyService i = s.getWSHttpBindingIMyService(); returnedValue = i.getSomething(2); // method call Can a java client communicate with a WCF webservice that is using wsHttpBinding? I have read that I might need to use WSIT (Metro) but am confused on how to proceed with that. Any help will be appreciated.

• How to get a list of items when using cassandra

  - by Blankman

  When using a nosql type datastore like Cassandra, how would you return a result set based on a column? e.g. SELECT * FROM Articles WHERE category='blah' ORDER BY datetime DESC is this something that you would store in a sql db and then pull the data from cassandra? Or can cassandra handle this type of query? (assuming millions of rows in a db) From what I understand, cassandra is great at key based lookups, confused if it can and should be used for getting a list of data back and paging that data also (and if it is highly performant)

• Simple Properties in Objective-C Classes

  - by tarnfeld

  Hey, I've bene working with Objective-C for a while now, and so far I have never really needed to craft my own classes, properly. I am a bit confused with the two arguments you can give the @property(a, b) declaration in a header file. When creating outlets to Interface Builder I usually do @property(nonatomic, retain) but I have no idea what this means. I'm writing a simple class which has a set of properties which will be set from the outside, like [instance setName:@"Bla Bla Bla"]; or I guess like instance.name = @"Bla@" but I would rather the first option. How would I declare this kind of property on a class? Thanks in advanced! Sorry for the n00bish question :-)

• Trouble setting up php Zend include path

  - by behrk2

  Hello, I am trying to set up a PHP path to my Zend Framework. I am very confused on how to do this. My Zend Framework is located at the following location on my server: amazon/ZendFramework-1.10.3-minimal I am going to be creating a couple of php files in the amazon/ directory that will require the Zend Framework. My include path is: include("ZendFramework-1.10.3-minimal/library/Zend/Service/Amazon.php"); This works, however inside of Amazon.php is the line require_once 'Zend/Rest/Client.php'; ...and then Client.php has more dependencies set up like that, and so on. How can I set up my include path so that Amazon.php and Client.php (and so on) can correctly reference the location of the Zend Framework? Thanks

• JBoss Seam: components injected into POJOs, but not Session Beans

  - by purecharger

  I have a Seam component that handles login, with the name "authenticator": @Name("authenticator") public class AuthenticatorAction implements Authenticator { @PersistenceContext private EntityManager em; @In(required=false) @Out(required=false, scope = SESSION) private User user; public boolean authenticate(){ ... } } This works just fine, Seam injects the EntityManager instance. However, as soon as I add the @Stateless annotation, none of the injection happens! In this case, the EntityManager instance is null upon entry to the authenticate() method. Another interesting note is that with a separate stateful session bean I have, the Logger instance in that class is only injected if I make it static. If i have it non-static, it is not injected. Thats fine for the logger, but for stateless session beans like that, I obviously can't have static member variables for these components. I'm confused because this authenticator is exactly how it is in the Seam booking example: a stateless session bean with a private member variable being injected. Any ideas?

• .htacces file. Can I block access to a directory without blocking access to the files within it?

  - by steph

  I'm building a website, but I'm not entirely sure what to do with the .htaccess file. Say for example I have a folder called pages which holds all my pages, can i deny access to someone if they type in www.website.com/pages so that they can't see the directory? I've tried putting the .htaccess file in the pages folder with the "deny from all" line and although it denies access, it's also denying access to the actual pages. Is there a way to do this without denying access to see the pages on the website, just denying access to the directory? Sorry if this doesn't make much sense, I'm so confused lol. Thanks for any help.

• Java Backgroundworker: Scope of Widget to be updated unclear

  - by erlord

  Hi all, I am trying to understand the mechanism of org.jdesktop.swingx.BackgroundWorker. Their javadoc presents following example: final JLabel label; class MeaningOfLifeFinder implements BackgroundListener { public void doInBackground(BackgroundEvent evt) { String meaningOfLife = findTheMeaningOfLife(); evt.getWorker().publish(meaningOfLife); } public void process(BackgroundEvent evt) { label.setText("" + evt.getData()); } public void done(BackgroundEvent evt) {} public void started(BackgroundEvent evt) {} } (new MeaningOfLifeFinder()).execute(); Apart from the fact that I doubt the result will ever get published, I wonder how label is passed to the process method, where it is being updated. I thought it's scope is limited to the outside of the BackgroudListener implementation. Quite confused I am ... any answers for me? Thanks in advance

• Verify mail server connection programmatically in ColdFusion

  - by Sergii

  I'm using custom SMTP servers and would like to verify the connection when user enters his own server credentials. Exactly the same type of check as Adobe CF and Railo allow to do when adding mail server. Sure, this does not guarantee that delivery will be working, but at least to check that entered server/username/pass are valid. I can see one tricky way: try to send the email with cfmail and check the mail log. But I believe that it can be done with more elegant. Is there any Java library available with standard ACF/Railo distro to help me? How would I use them? Examples are highly appreciated. Thanks in advance. EDIT: Please don't be confused with Java tag present. Solution needed in CFML. Though it can use some Java libraries, if applicable.

• Simple object creation with DIY-DI?

  - by Runcible

  I recently ran across this great article by Chad Perry entitled "DIY-DI" or "Do-It-Yourself Dependency Injection". I'm in a position where I'm not yet ready to use a IoC framework, but I want to head in that direction. It seems like DIY-DI is a good first step. However, after reading the article, I'm still a little confused about object creation. Here's a simple example: Using manual constructor dependency injection (not DIY-DI), this is how one must construct a Hotel object: PowerGrid powerGrid; // only one in the entire application WaterSupply waterSupply; // only one in the entire application Staff staff; Rooms rooms; Hotel hotel(staff, rooms, powerGrid, waterSupply); Creating all of these dependency objects makes it difficult to construct the Hotel object in isolation, which means that writing unit tests for Hotel will be difficult. Does using DIY-DI make it easier? What advantage does DIY-DI provide over manual constructor dependency injection?

• How do I set the bake command to use a different template in cakephp

  - by Gaurav Sharma

  Hi all, I wanted bake command to bake a view of my liking. So I searched bakery and found this Modify-default-HTML-produced-by-baked-templates. But after reading this I was not able to modify the template because I wanted to define some CSS in it and those files are not containing any CSS code (they contain only php code inside them). Also if I have designed my own CSS file for the new template then how do I tell bake command to pick that specified css file for new template ? I am totally confused over here. Has anybody done this similar kinda work using cakePHP. Any help would be greatly appreciable. NOTE: I am using cakePHP v 1.3 latest stable release. Thanks

• Where to start with Direct2d?

  - by ShrimpCrackers

  Interested in learning Direct2d to create a Windows 8 app, but after 2 hours of research I'm thoroughly confused. Samples like this (Creating a Simple Direct2D Application) seem to assume you know what an HWND and HRESULT is, and how the Windows API works in general. My question is this: do you need an understanding of the Win API, COM, OLE, and all this other Windows stuff in order to get a good grasp on Direct2d/3d? All the other barebones tutorials assume that you know all this stuff and I don't really know where to start. The startup D2D project in VS 2012 gives you a bunch of files but there's no main or WinMain... How does this program even start?

• Choose Graph API or old REST API for Facebook application

  - by Andree

  Hi there! I should have asked this in Facebook developer forum instead, but somehow I can't register to the forum and the Facebook connect feature is not working at the time I'm writing this. Anyway, I am still confused whether to use Graph API or the old REST API for my Facebook app. Generally, this is what I want to achieve in my app: Get profile picture and name of the user. Get profile picture and name of the user's friends who are also using my app. Post into the user's stream. Allow users to invite their friends to use the application. Can someone provide me an insight, which one is better for my application?

• issue in list of dict

  - by gaggina

  class MyOwnClass: # list who contains the queries queries = [] # a template dict template_query = {} template_query['name'] = 'mat' template_query['age'] = '12' obj = MyOwnClass() query = obj.template_query query['name'] = 'sam' query['age'] = '23' obj.queries.append(query) query2 = obj.template_query query2['name'] = 'dj' query2['age'] = '19' obj.queries.append(query2) print obj.queries It gives me [{'age': '19', 'name': 'dj'}, {'age': '19', 'name': 'dj'}] while I expect to have [{'age': '23' , 'name': 'sam'}, {'age': '19', 'name': 'dj'}] I thought to use a template for this list because I'm gonna to use it very often and there are some default variable who does not need to be changed. Why does doing it the template_query itself changes? I'm new to python and I'm getting pretty confused.

• Should I Return "500" or "404" if a Requested Image is not Found?

  - by Michael Robinson

  I work with code written by other people, occasionally I am left somewhat confused and at these times Stack Overflow saves me. Please, save me again. Our site allows people to upload images and later embed them within text in our site like so: <img src="http://site.com/image_script.php?p=some_image_identifier"/> My question is: If the identifier, "p", does not lead us to an image should the server return "500" or "404"? I would have thought it should be "404", but that's not what is happening right now.

• Adding a dynamic-height UITableView into a scrolling view?

  - by Greg

  Hello all – I'm getting into iPhone development and have hit my first confusing UI point. Here's the situation: My app is tab-based, and the view that I'm confused about has a static featured content image at the top, then a dynamic list below into which X headlines are loaded. My goal is to have the height of the headline table grow as elements are added to it, and then to have the whole view scroll (both featured image on top and headline list below). So, I guess my question comes in two parts: 1) First, how do you set up a dynamic-height table view that will grow as cells are added to it. So far I've only been able to have my tables handle their own scrolling. 2) Then, what is the root NIB view that the featured image and the table should live in to enabled scrolling? I've dropped oversized content into a UIScrollView now, although did seem to have any success with having it automatically scroll. Thanks in advance for any help on this subject!

• How do i redirect to a GET request from a POST request on GAE

  - by user259349

  Hello everyone, i am writing an FBML app on facebook hosted in GAE. Facebook will talk to your hosted app only vai POST (im sure this is the cause, but please do correct me if i'm wrong). So im faced with the issue that inside of my POST method, i need to redirect to facebook OAuth authroize URL. But i can only send a GET request. How can i do that? At the moment i'm doing class OauthHandler(webapp.RequestHandler): def post(self): # blablablab request.redirect(oauth_uri) Which is wrong since the oauth_uri is only responding to GET. Further more, OAuth will redirect back to my redirect handler through GET, but i cant! i can only do post. So i'm confused. ideas? Thanks in advance

• Classes, constructor and pointer class members

  - by pocoa

  I'm a bit confused about the object references. Please check the examples below: class ListHandler { public: ListHandler(vector<int> &list); private: vector<int> list; } ListHandler::ListHandler(vector<int> &list) { this->list = list; } Here I would be wasting memory right? So the right one would be: class ListHandler { public: ListHandler(vector<int>* list); private: vector<int>* list; } ListHandler::ListHandler(vector<int>* list) { this->list = list; } ListHandler::~ListHandler() { delete list; }

• How do I blur (ios7 style) a section of an image in a UITableViewCell?

  - by George McKibbin

  I've got a UIImageView that takes up the whole cell and shows an image. I'd like to blur the bottom third of the view in the iOS7 style (we're targeting iOS7). There will be a label over the blurred part. The issue seems to be that I can't "screenshot" the UIImageView right as I am setting up the cell in tableView:cellForRowAtIndexPath: as it hasn't loaded yet. Although i've even tried setting up a timer for a 0.1 second delay and that also doesn't work. I've tried the stuff on http://damir.me/posts/ios7-blurring-techniques I've tried https://github.com/justinmfischer/7blur I'd like to use the new screenshotting API drawViewHierarchyInRect:afterScreenUpdates: I'd also like to use apple's sample code UIImage+ImageEffects The only thing that has worked so far has been to just put a UIToolbar in but the performance is really slow. I don't need dynamic updates. I've managed to get the following effect a few times but it has just tinted the view and hasn't actually blurred anything so I'm a bit confused.

• xml with special character, encoding utf-8

  - by Sergio Morieca

  I have a few simple questions, because I got confused reading all difference responses. 1) If I have an xml with prolog: and I'm going to unmarshall it with Java (for example: JaXB). I suppose, that I can't put CROSS OF LORRAINE (http://www.fileformat.info/info/unicode/char/2628/index.htm) inside, but I can put "\u2628", correct? 2) I've also heard that UTF-8 doesn't contain it, but anything in Unicode can be saved with encoding UTF-8 (or UTF-16), and here is an example from this page: UTF-8 (hex) 0xE2 0x98 0xA8 (e298a8) Is my reasoning correct? Can I use this form and put it in the xml with utf-8 encoding?

• Drupal Customizing User Registration Form

  - by Asif Mulla

  Hi All, I am newbie in Drupal 6. I am looking for customizing User registration form. Apparently found that while adding user using Admin login allows registration form to have fields like email address, username, password,confirm password, etc with validations. But when anonymous use wants to register, then only fields like email address and username are displayed. I tried with Profile module available. But now how could I add some fields (password, confirm password, terms & condition check and receive news letter check box)and behavior (password, confirm password validation etc.)? If I am adding such fields they are also get visible in AdminAdd user form resulting duplicate fields like Password,Confirm password. Could you please suggest me how can I do this? I tried googling but confused me a lot as I am beginner to Drupal.

• Prototype's Ajax.Request not working in Chrome

  I am just doing a simple Ajax.Request call using the newest version of Prototype. It works fine in Firefox, Internet Explorer, and even Safari... but not in Chrome. Here is my code... alert(url); new Ajax.Request(url, { method: 'get', onSuccess: function(transport) { alert('test'); } }); It pops up he URL alert but the test alert never comes up. Like I said it does in every other browser. I am not getting any javascript errors and I have used Firebug. I did a console.log on each event and it gets to the onLoading stage of Ajax.Request but never onLoaded. Very confused... ?
