  • Trying to Unit Test A Class That Makes DB Queries Using Hibernate And Can't Get Session Created...

    - by Jared Michaels
    I am trying to implement JUnit tests for a class that performs DB queries using Hibernate. When I create the class under test, I get access to the session through the factory by doing the following: InitialContext context = new InitialContext(); sessionFactory = (SessionFactory) context.lookup(hibernateContext); This works fine when I deploy this to JBoss 5.1. I am trying to figure out how to get this to work with my JUnit test. I keep getting an exception stating that I "Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial". I've searched high and low but haven't been able to find any information about what specifically I need to do to get this to work. I am not using Spring or any frameworks, just plain old Java and JUnit.

  • Overriding properties of child view controller vs setting them via parent view controller

    - by robinjam
    If you want to modify the default behaviour of a View Controller by changing the value of one of its properties, is it considered better form to instantiate the class and set its property directly, or subclass it and override the property? With the former it would become the parent View Controller's responsibility to configure its children, whereas with the latter the children would effectively configure themselves. EDIT: Some more information: The class I am referring to is FetchedTableViewController, a subclass of UITableViewController that I made to display the results of a Core Data fetch operation. There are two places I want to display the results of a fetch, and they each have different fetch requests. I'm trying to decide whether it's better to create a subclass for each one, and override the fetchRequest property, or make it the responsibility of the parent controller to set the fetchRequest property for its children.

  • How do I read the cache of Chrome and Firefox programmatically on the Mac?

    - by John Gallagher
    Background I want to access the cache of Chrome and Firefox in my Cocoa application. I need to get the HTML for pages accessed recently. Safari is a piece of cake - all this information is available in SQLite data stores, but not so in Chrome and Firefox. The Problem For Firefox, the cache is in /Library/Caches/Firefox/Profiles/xxx.default/Cache with filenames _CACHE_001_ _CACHE_002_ _CACHE_003_ and _CACHE_MAP_ For Chrome, the cache is in /Library/Caches/Google/Chrome/Default/Cache with filenames data_0 data_1 data_2 and data_3 What I've tried The only article I can find that sheds any light on what format these caches are in is here. It recommends a Cache Viewer tool, but doesn't explain how one might do this programmatically. Questions Is there any way of reconstructing this data using command line tools or the Cocoa framework? Or is it much too low level? Is there another way of getting at the HTML of recent web pages that I don't know about?

  • Hos to group the complex list objects by using Linq

    - by Daoming Yang
    I want to select and group the products, and rank them by the number of times they occur. For example, I have an OrderList each of order object has a OrderProductVariantList(OrderLineList), and each of OrderProductVariant object has ProductVariant, and then the ProductVariant object will have a Product object which contains product information. A friend helped me with the following code. It could be compiled, but it did not return any value/result. I used the watch window for the query and it gave me "The name 'query' does not exist in the current context". Can anyone help me? Many thanks. var query = orderList.SelectMany( o => o.OrderLineList ) // results in IEnumerable<OrderProductVariant> .Select( opv => opv.ProductVariant ) .Select( pv => p.Product ) .GroupBy( p => p ) .Select( g => new { Product = g.Key, Count = g.Count() });

  • Javascript: Link with Chinese characters in Internet Explorer

    - by Dennis Coretree
    I have a problem with a link containing Chinese characters that is send to a javascript file in Internet Explorer. Generally that link is created by PHP and looks like this in IE: www.example.com/%E6%B7%AC%E7%81%AB%E6%B2%B9_ASIN5034CN.pdf In firefox it looks like this: www.example.com/???_ASIN5034CN.pdf Both work in that direct way. I need to pass that link to a javascript that popups on the page and it will be displayed after the user entered her/his contact information. This also works on firefox and other browsers but in IE that link is transfered to this which does not work anymore: www.example.com/æ·¬ç«æ²¹_ASIN5034CN.pdf I tried to do some encoding on it with encodeURIComponent but still no success. So the link is passed correctly to the javascript but it is totally screwed up only by IE. Thx for any advice on that problem.

    - by cmedeiros

  • GenerateBootstrapper fails to create a working setup.exe

    - by Darren
    I’m seeing some odd behaviour I can’t explain. I'm using wix to generate a msi and using the msbuild GenerateBootstrapper task to handle pre-requisites. It all seems to build correctly i.e. there are no error or warnings but the generated setup.exe won’t run. It gives a nice blank error dialog and the event log gives about the same information. The kicker is that if I drop to the command line and run msbuild manually on the project and specify the bootstrapper target it generates a correct and working setup.exe. I've used this wix article as a base and a number of questions on StackOverflow to no avail. Has anyone seen this behaviour before, better still a fix?

  • Checked equivalent to IllegalArgumentException?

    - by jv1975oid
    I have a method that takes an enum as a parameter and returns some information dependent on that parameter. However, that enum contains some values which should not be handled, and should raise an error condition. Currently the method throws an IllegalArgumentException but I would like this to be a checked exception to force callers to catch it (and return gracefully, logging an error). Is there something suitable or should I create my own Exception subclass? I'm open to other patterns as well. A reasonable reaction would be that all values of the enum should be handled, but that isn't the case. When a new value is added to the enum, I want to make sure that this method does the right thing - alerting a human is preferable to using some default return value in this case. Thanks for any advice.

I've succesfully run Joomla on the same server so I'm pretty sure the following information are correct: host: localhost user: user pass: pass databaseName = servername_databasename I've set the following line in settings.php file: $db_url = 'mysql://user:password@localhost/servername_databasename'; but what I get is this: If you are the maintainer of this site, please check your database settings in the settings.php file and ensure that your hosting provider's database server is running. For more help, see the handbook, or contact your hosting provider. I don't get any other error message such as: database doesn't exist, user/pass wrong.. just this. The database is running, I can access with phpmyadmin. I've tried both "mysql" and "mysqli". The host is a private server (IIS Microsoft), the database is Mysql The database and website files upload have also been succesfull.. so I dunno what to do to fix this issue. thanks

  • Flex 3 / ColdFusion Session Issue?

    - by dcolumbus
    Alright so this is an odd one... I have an application built in ColdFusion with a lot of the interactivity done with Flex. When a user logs in, there are session variables, as well as the client session that is evoked. When you browse to any given Flex Application, the variables are read in a used accordingly... however, on Windows (it seems XP and maybe others) for some reason session information like USER are randomly undefined... Could this be an issue with the session timing out? Even if I force a logout and log back in, it doesn't really seem to fix the issue... mind you, I cannot duplicate the bug myself, but it constantly happens on PCs.

  • Stack trace for C++ using gcc

    - by dimba
    We use stack traces in proprietary assert like macro to catch developer mistakes - when error is caught, stack trace is printed. I find gcc's pair backtrace()/backtrace_symbols() methods insufficient: Names are mangled No line information 1st problem can be resolved by abi::__cxa_demangle. However 2nd problem s more tough. I found replacement for backtrace_symbols(). This is better than gcc's backtrace_symbols(), since it can retrieve line numbers (if compiled with -g) and you don't need to compile with -rdynamic. Hoverer the code is GNU licenced, so IMHO I can't use it in commercial code. Any proposals?

  • Programming and art

    - by user353874
    Specialized software does play a major role in every business field. Games provide new realities and are proved child development tools. Communication got a new meaning. Information never traveled so fast. And programming is never referred to as an art form. Why is that? Programming is not romantic and not natural so we don't feel naturally attached to it. Basically, our emotions don't fit programming. But it's really cool and better than art. :D

  • How do I sync Dreamweaver site definitions across 2 computers?

    - by baritoneuk
    I use Dreamweaver on my laptop and Desktop PC and frequently change between them. I keep all my sites synced using Syncplicity (similar to Dropbox, which indecently I also use) I want my site definitions to be synced across the two computers. If I add a new site on one computer I want it to appear on the other one. I know I can export all sites on one computer and then get Syncplicity to sync the files to the other computer at which point I can import them. However this relies on me remembering to do this each time I add a new site, and it's also quite time consuming. As far as I can tell, Dreamweaver (at least upto CS4- not sure about CS5) stupidly stores the site definitions in the registry. I really don't know why they do this- if they stored it in xml files then I could easily sync the information. Does anyone know if what I am asking is possible?

  • ASP MVC Populate drop down list on jQuery add table row

    - by Jacob Huggart
    I have a page with several drop down lists that all have the same contents. The page starts out with only three ddls, but more need to be added based on user input. There is also other information associated with the drop down lists that is all in a table. So, when the user clicks a link I add a new row of textboxes and drop down lists to a table. When I add a row to my table, the new drop down lists are empty because there is no view data associated with them. How can I use ajax or jquery to pull the viewdata that I need to populate new drop down lists?

  • Project design / FS layout for large django projects

    - by rcreswick
    What is the best way to layout a large django project? The tutuorials provide simple instructions for setting up apps, models, and views, but there is less information about how apps and projects should be broken down, how much sharing is allowable/necessary between apps in a typical project (obviously that is largely dependent on the project) and how/where general templates should be kept. Does anyone have examples, suggestions, and explanations as to why a certain project layout is better than another? I am particularly interested in the incorporation of large numbers of unit tests (2-5x the size of the actual code base) and string externalization / templates.

  • JavaScript - Textarea Selection

    - by brad
    The Problem I am working on an in-browser editor within a textarea. I have started looking for some information on dealing with textarea selection and found this jQuery plugin that does some simple manipulation. However, it doesn't explain what's going on. The Question Where can I find a good resource on Textarea Selection in JavaScript, preferably with a description of both pre-DOM3 and post-DOM30 scenarios? [Edit] In a great answer from Borgar, I have found several different places to start with contentEditable, selectionStart, and selectionEnd. I'll be looking into these things and posting any good tutorials I might find.
