  • Débat Java : Quelles sont les limites du framework Web Apache Wicket ? Confrontez vos points de vue

    Bonjour Bien qu'appréciant beaucoup wicket, il n'en est pas moins que ce framework présente des limites. C'est d'ailleurs l'intitulé d'un post sur "Tom's Quest" : les limites de Wicket. Les points évoqués sont (le détail sur le blog):Le markup n'est pas toujours prévisualisable Wicket ne tient pas la charge Tester une application Wicket est difficile Les URLs générées sont moches Spring Security s'intègre mal à Wicket Wicket n'est pas un framework managé Wicket n'est pas outillé L'intégrable avec des frameworks JavaScript est difficile A noter que l'auteur ne fait pas que lister d'...

  • Develop web site from existing software or cherry pick and use a web framework?

    - by erisco
    A small team and I are tasked with developing a web site. The client has referenced a particular open source project (we'll call it X) when describing some of the features. Because of this, the team wants to start with X and adapt it to satisfy the client. I have looked at X and its code and, in my opinion, it would be unwise. However, my experience is limited, and could really benefit from the insights of others so that I can figure out what I should be asserting as the right direction for the team. My red flags are going up and this is why. X was developed in the earlier days of PHP; 500 line blocks of code are the norm; global variables are abundant; giant switch cases are the norm for switching between which page is shown. There is no clear mapping between URL and where the code for that page sits. From a feature-set standpoint, X is actually software specialized for a different task and has dozens of features we don't need or have use for that come as core assumptions. We will be unable to adapt X through its plugin system. That said, there are a few features which can be mapped, with some modification, to suit our purposes. I believe this is the attraction the team feels. I would feel comfortable if, instead of using X directly, we lifted what is salvageable and useful to us. We can then use that code, and the same 3rd party libraries X is using, in a new code base built on top of a PHP web framework (particularly Agavi, so you understand what I mean by 'web framework'). The web framework gives us a strong MVC structure and provides the common facilities for web development, or adapters to work with 3rd party libraries that do so. We will also have a clean slate feature-wise to work from, which means we can work additively instead of subtractively. Because the code base is better structured, and contains none of what we don't need, it will be easier to document, which is a critical requirement of our client. So to summarize, the team wants to use X, whereas I want to take the bits we can from X and use a web framework instead. I want to bounce this opinion off of other's experiences so that I can be more informed. Thanks for your insight.

  • Allow different headers on different servers using WFF

    - by Brian
    We've got multiple web servers configured in a cluster using Microsoft's Web Farm Framework. One of the things I like to do to help debugging is to create a header in IIS that identifies the server that handled the request. Unfortunately when I try to do this, WFF sets the headers to the same value on all the servers. Is there a way around this? I tried looking into using skipDirectives, but I can't find any documentation on it (other than a little bit showing how to use it to skip directories and bindings). If there is documentation on this, please link to it! I would like to be able to read up more on it in case I need to do other things as well.

  • License compatibility question

    - by Ivaylo Slavov
    I have a question regarding software licenses. I plan to put a license to a framework that I have written. My intention is that the license should be open, in order to maintain a community. Also I want to control when a new version is released and which changes will be included. The license should allow the framework to be used with commercial products, therefore respecting their own license. I have done some quick research and I decided to double license my work under the Apache License 2.0 (ASL) and Eclipse Public License (EPL). My point is that the EPL will provide me the ability to control the release cycle as well as the contributions to the project and the Apache license will take care for any patents a 3rd party might want to use in a derived work. Also both are open licenses. My question is related to the GLP and LGPL licenses. If I have the above licenses to my framework, will it be possible and legal, for someone to create a derived work of my framework, that is also a derived work of, or links a library that is under the LGPL license? Thanks in advance. EDIT: To be clear I will explain how I expect things to work. The framework will define some common API for certain functionalities as well as a Wrapper class that will invoke an implementation of that API. The Wrapper will be part of the framework, but it will internally call the actual implementation. This implementation should be in a separate library, and such libraries I would like to be developed and maintained by community. Surely the community will have to access the framework but I want to limit changes to the framework by the community but I want to provide freedom for any API implementation (a derived work of the framework). The framework will enable flexible configuration mechanisms that will tell which implementation of an API will be used.

  • What is a proper server for this website

    - by zaidfarekh
    We are using zend framework, doctrine on our website, that will have the minimum of 2000 users daily, please consider that we prefer that the server has opcode caching. And any available technology that speeds up php performance. We have heard that zend server offers an optimal performance for php. Please recommend a hosting server or a vps plan, that can handle such an application. given that our application has some kind of social networking and it applies alot of ajax requests even in minimal usage of the website, for example in 30 min we may have up to 400 requests from an individual user. Thank you in advance

  • Mapping and metadata information could not be found for EntityType Exception

    - by dcompiled
    I am trying out ASP.NET MVC Framework 2 with the Microsoft Entity Framework and when I try and save new records I get this error: Mapping and metadata information could not be found for EntityType 'WebUI.Controllers.PersonViewModel' My Entity Framework container stores records of type Person and my view is strongly typed with class PersonViewModel which derives from Person. Records would save properly until I tried to use the derived view model class. Can anyone explain why the metadata class doesnt work when I derive my view model? I want to be able to use a strongly typed model and also use data annotations (metadata) without resorting to mixing my storage logic (EF classes) and presentation logic (views). // Rest of the Person class is autogenerated by the EF [MetadataType(typeof(Person.Metadata))] public partial class Person { public sealed class Metadata { [DisplayName("First Name")] [Required(ErrorMessage = "Field [First Name] is required")] public object FirstName { get; set; } [DisplayName("Middle Name")] public object MiddleName { get; set; } [DisplayName("Last Name")] [Required(ErrorMessage = "Field [Last Name] is required")] public object LastName { get; set; } } } // From the View (PersonCreate.aspx) <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<WebUI.Controllers.PersonViewModel>" %> // From PersonController.cs public class PersonViewModel : Person { public List<SelectListItem> TitleList { get; set; } } // end class PersonViewModel

  • How to debug MySQL/Doctrine2 Queries?

    - by jiewmeng
    I am using MySQL with Zend Framework & Doctrine 2. I think even if you don't use Doctrine 2, you will be familiar with errors like SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ASC' at line 1 The problem is that I don't see the full query. Without an ORM framework, I could probably echo the sql easily, but with a framework, how can I find out what SQL its trying to execute? I narrowed the error down to $progress = $task->getProgress(); $progress is declared // Application\Models\Task /** * @OneToMany(targetEntity="TaskProgress", mappedBy="task") * @OrderBy({"seq" = "ASC"}) */ protected $progress; In MySQL, the task class looks like CREATE TABLE `tasks` ( `id` int(11) NOT NULL AUTO_INCREMENT, `owner_id` int(11) DEFAULT NULL, `assigned_id` int(11) DEFAULT NULL, `list_id` int(11) DEFAULT NULL, `name` varchar(60) NOT NULL, `seq` int(11) DEFAULT NULL, PRIMARY KEY (`id`), KEY `tasks_owner_id_idx` (`owner_id`), KEY `tasks_assigned_id_idx` (`assigned_id`), KEY `tasks_list_id_idx` (`list_id`), CONSTRAINT `tasks_ibfk_1` FOREIGN KEY (`owner_id`) REFERENCES `users` (`id`), CONSTRAINT `tasks_ibfk_2` FOREIGN KEY (`assigned_id`) REFERENCES `users` (`id`), CONSTRAINT `tasks_ibfk_3` FOREIGN KEY (`list_id`) REFERENCES `lists` (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1$$

  • Magento resource model for table with compound primary key

    - by sdek
    I am creating a custom module for a Magento ecommerce site, and the module will center around a new (ie, custom) table that has a compound/composite primary key, or rather the table has two columns that make up the primary key. Does anybody know how to create your models/resource models based on a table with a compound key? To give a few more details, I have looked up several tutorials and also used the excellent moduleCreator script. But it seems like all the tutorials revolve around the table having a PK with just one column in it. Something like this: class <Namespace>_<Module>_Model_Mysql4_<Module> extends Mage_Core_Model_Mysql4_Abstract { public function _construct(){ $this->_init('<module_alias>/<table_alias>', '<table_primary_key_id>'); } } Also, I just noticed that looking at the database model almost all tables have a single primary key. I understand this has much to do with the EAV-style db structure, but still is it possible to use a table with a compound PK? I want to stick with the Magento framework/conventions if possible. Is it discouraged? Should I just change the structure of my custom table to have some dummy id column? I do have the ability to do that, but geez! (Another side note that I thought I would mention is that it looks like the Zend Framework provides a way to base a class on a table with compound primary key (see Example #20 on this page - about half-way down), so it seems that the Magento framework should also provide for it... I just don't see how.)

  • ZF2: Get url parameters in controller

    - by koko
    I have experienced Zend Framework 1 and I've build some apps with that framework. Now, I'm experimenting Zend Framework 2, but I'm stuck on the url parameters. I've setup my routing like this: // Setup for router and routes 'Zend\Mvc\Router\RouteStack' => array( 'parameters' => array( 'routes' => array( 'default' => array( 'type' => 'Zend\Mvc\Router\Http\Segment', 'options' => array( 'route' => '/[:slug]', 'constraints' => array( 'slug' => '[a-zA-Z][a-zA-Z0-9_\/-]*' ), 'defaults' => array( 'controller' => 'Htmlsite\Controller\BootController', 'action' => 'index', 'slug' => 'home' ), ), ), 'home' => array( 'type' => 'Zend\Mvc\Router\Http\Literal', 'options' => array( 'route' => '/', 'defaults' => array( 'controller' => 'Htmlsite\Controller\BootController', 'action' => 'index', ), ), ), ), ), ), As you can see, I've tried to make a variable slug. How can I access this variable?

  • Alpha blending colors in .NET Compact Framwork 2.0

    - by Adam Haile
    In the Full .NET framework you can use the Color.FromArgb() method to create a new color with alpha blending, like this: Color blended = Color.FromArgb(alpha, color); or Color blended = Color.FromArgb(alpha, red, green , blue); However in the Compact Framework (2.0 specifically), neither of those prototypes are valid, you only get: Color.FromArgb(int red, int green, int blue); and Color.FromArgb(int val); The first one, obviously, doesn't even let you enter an alpha value, but the documentation for the latter shows that "val" is a 32bit ARGB value (as 0xAARRGGBB as opposed to the standard 24bit 0xRRGGBB), so it would make sense that you could just build the ARGB value and pass it to the function. I tried this with the following: private Color FromARGB(byte alpha, byte red, byte green, byte blue) { int val = (alpha << 24) | (red << 16) | (green << 8) | blue; return Color.FromArgb(val); } But no matter what I do, the alpha blending never works, the resulting color always as full opacity, even when setting the alpha value to 0. Has anyone gotten this to work on Compact Framework?

  • Cannot figure out how to take in generic parameters for an Enterprise Framework library sql statemen

    - by KallDrexx
    I have written a specialized class to wrap up the enterprise library database functionality for easier usage. The reasoning for using the Enterprise Library is because my applications commonly connect to both oracle and sql server database systems. My wrapper handles both creating connection strings on the fly, connecting, and executing queries allowing my main code to only have to write a few lines of code to do database stuff and deal with error handling. As an example my ExecuteNonQuery method has the following declaration: /// <summary> /// Executes a query that returns no results (e.g. insert or update statements) /// </summary> /// <param name="sqlQuery"></param> /// <param name="parameters">Hashtable containing all the parameters for the query</param> /// <returns>The total number of records modified, -1 if an error occurred </returns> public int ExecuteNonQuery(string sqlQuery, Hashtable parameters) { // Make sure we are connected to the database if (!IsConnected) { ErrorHandler("Attempted to run a query without being connected to a database.", ErrorSeverity.Critical); return -1; } // Form the command DbCommand dbCommand = _database.GetSqlStringCommand(sqlQuery); // Add all the paramters foreach (string key in parameters.Keys) { if (parameters[key] == null) _database.AddInParameter(dbCommand, key, DbType.Object, null); else _database.AddInParameter(dbCommand, key, DbType.Object, parameters[key].ToString()); } return _database.ExecuteNonQuery(dbCommand); } _database is defined as private Database _database;. Hashtable parameters are created via code similar to p.Add("@param", value);. the issue I am having is that it seems that with enterprise library database framework you must declare the dbType of each parameter. This isn't an issue when you are calling the database code directly when forming the paramters but doesn't work for creating a generic abstraction class such as I have. In order to try and get around that I thought I could just use DbType.Object and figure the DB will figure it out based on the columns the sql is working with. Unfortunately, this is not the case as I get the following error: Implicit conversion from data type sql_variant to varchar is not allowed. Use the CONVERT function to run this query Is there any way to use generic parameters in a wrapper class or am I just going to have to move all my DB code into my main classes?

  • HTML-like GUI Framework in Java

    - by wintermute
    I was recently brought onto a project where we are developing a lot GUI elements for BlackBerry devices. The standard RIM APIs are pretty basic, almost never do what is required and are difficult or impossible to extend, so we end up re-implementing chunks of it. Currently the code we have isn't super organized and factored so there are lots of little tricks that get implemented over and over again. I had a thought about how to aid development efforts on this platform and wanted to see if the community could tell me if I'm still sane or if I've gone totally nuts. By far, the biggest organizational problem I've run into is making sure that each screen is laid out properly with proper padding and such. The current approach is to manually keep track of padding like so: protected void sublayout(int width, int height) { final int padding = 5; int y = padding; int x = padding; layoutChild(_someChild, width - padding * 2, height / 3 - padding * 2); setPositionChild(_someChild, x, y); y += _someChild.getHeight() + padding; // Calculate where to start drawing next. /* ... snipped ... */ } As you can see, positioning elements on a screen is a nightmare due to the tedium. I have investigated other GUI frameworks but, for a variety of reasons, it is difficult to find one that suites our purposes. One potential solution that came to me is to create a GUI framework who's API resembles HTML/CSS. This would allow for things like padding, margins, borders and colours to be handled through a sort of CSS API while the content would be organized using the HTML part of the API. It might look something like this: public class OptionsScreen extends Document { public OptionsScreen() { // You would set the style (like CSS style) through the constructor. Div content = new Div(new Style(new Padding(5), Color.BLACK)); // Then build up a tree of elements which can each have their own style's. // Each element knows how to draw itself, but it doesn't have to worry about // manually handling things like padding. // content.addChild(new P("This is a paragraph", new Style(new Padding(), Color.RED))); Ul list = new Ul(); list.addChild(new Li("item 1")); list.addChild(new Li("item 2")); content.addChild(list); addChild(content); } } I can imagine this making it easier to customize the UI of our app (which is very important) with different fonts, colours and layouts. Does this idea belong on The Daily WTF or do you think there is some promise?

  • .NET Framework generates strange DCOM error

    - by Anders Oestergaard Jensen
    Hello, I am creating a simple application that enables merging of key-value pairs fields in a Word and/or Excel document. Until this day, the application has worked out just fine. I am using the latest version of .NET Framework 4.0 (since it provides a nice wrapper API for Interop). My sample merging method looks like this: public byte[] ProcessWordDocument(string path, List<KeyValuePair<string, string>> kvs) { logger.InfoFormat("ProcessWordDocument: path = {0}", path); var localWordapp = new Word.Application(); localWordapp.Visible = false; Word.Document doc = null; try { doc = localWordapp.Documents.Open(path, ReadOnly: false); logger.Debug("Executing Find->Replace..."); foreach (Word.Range r in doc.StoryRanges) { foreach (KeyValuePair<string, string> kv in kvs) { r.Find.Execute(Replace: Word.WdReplace.wdReplaceAll, FindText: kv.Key, ReplaceWith: kv.Value, Wrap: Word.WdFindWrap.wdFindContinue); } } logger.Debug("Done! Saving document and cleaning up"); doc.Save(); doc.Close(); System.Runtime.InteropServices.Marshal.ReleaseComObject(doc); localWordapp.Quit(); System.Runtime.InteropServices.Marshal.ReleaseComObject(localWordapp); logger.Debug("Done."); return System.IO.File.ReadAllBytes(path); } catch (Exception ex) { // Logging... // doc.Close(); if (doc != null) { doc.Close(); System.Runtime.InteropServices.Marshal.ReleaseComObject(doc); } localWordapp.Quit(); System.Runtime.InteropServices.Marshal.ReleaseComObject(localWordapp); throw; } } The above C# snippet has worked all fine (compiled and deployed unto a Windows Server 2008 x64) with latest updates installed. But now, suddenly, I get the following strange error: System.Runtime.InteropServices.COMException (0x80080005): Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)). at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck) at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache) at System.RuntimeType.CreateInstanceDefaultCtor(Boolean publicOnly, Boolean skipVisibilityChecks, Boolean skipCheckThis, Boolean fillCache) at System.Activator.CreateInstance(Type type, Boolean nonPublic) at Meeho.Integration.OfficeHelper.ProcessWordDocument(String path, List`1 kvs) in C:\meeho\src\webservices\Meeho.Integration\OfficeHelper.cs:line 30 at Meeho.IntegrationService.ConvertDocument(Byte[] template, String ext, String[] fields, String[] values) in C:\meeho\src\webservices\MeehoService\IntegrationService.asmx.cs:line 49 -- I googled the COM error, but it returns nothing of particular value. I even gave the right permissions for the COM dll's using mmc -32, where I allocated the Word and Excel documents respectively and set the execution rights to the Administrator. I could not, however, locate the dll's by the exact COM CLSID given above. Very frustrating. Please, please, please help me as the application is currently pulled out of production.

  • Does anyone have database, programming language/framework suggestions for a GUI point of sale system

    - by Jason Down
    Our company has a point of sale system with many extras, such as ordering and receiving functionality, sales and order history etc. Our main issue is that the system was not designed properly from the ground up, so it takes too long to make fixes and handle requests from our customers. Also, the current technology we are using (Progress database, Progress 4GL for the language) incurs quite a bit of licensing expenses on our customers due to mutli-user license fees for database connections etc. After a lot of discussion it is looking like we will probably start over from scratch (while maintaining the current product at least for the time being). We are looking for a couple of things: Create the system with a nice GUI front end (it is currently CHUI and the application was not built in a way that allows us to redesign the front end... no layering or separation of business logic and gui...shudder). Create the system with the ability to modularize different functionality so the product doesn't have to include all features. This would keep the cost down for our current customers that want basic functionality and a lower price tag. The bells and whistles would be available for those that would want them. Use proper design patterns to make the product easy to add or change any part at any time (i.e. change the database or change the front end without needing to rewrite the application or most of it). This is a problem today because the Progress 4GL code is directly compiled against the database. Small changes in the database requires lots of code recompiling. Our new system will be Linux based, with a possibility of a client application providing functionality from one or more windows boxes. So what I'm looking for is any suggestions on which database and/or framework or programming language(s) someone might recommend for this sort of product. Anyone that has experience in this field might be able to point us in the right direction or even have some ideas of what to avoid. We have considered .NET and SQL Express (we don't need an enterprise level DB), but that would limit us to windows (as far as I know anyway). I have heard of Mono for writing .NET code in a Linux environment, but I don't know much about it yet. We've also considered a Java and MySql based implementation. To summarize we are looking to do the following: Keep licensing costs down on the technology we will use to develop the product (Oracle, yikes! MySQL, nice.) Deliver a solution that is easily maintainable and supportable. A solution that has a component capable of running on "old" hardware through a CHUI front end. (some of our customers have 40+ terminals which would be a ton of cash in order to convert over to a PC). Suggestions would be appreciated. Thanks [UPDATE] I should note that we are currently performing a total cost analysis. This question is intended to give us a couple of "educated" options to look into to include in or analysis. Anyone who could share experiences/suggestions about client/server setups would be appreciated (not just those who have experience with point of sale systems... that would just be a bonus).

  • Windows 2012 Server: Enable .NET 3.5

    - by Meengla
    I have a Windows 2012 Server which needs .NET 3.5 installed. For background info/solutions, please see this: http://sqlblog.com/blogs/sergio_govoni/archive/2013/07/13/how-to-install-netfx3-on-windows-server-2012-required-by-sql-server-2012.aspx I have tried this but it doesn't work for me. Here is what I am trying: Using a Windows 2012 ISO file, 'mount' on the 2012 Server as 'D' drive and then tried both GUI and Command prompt. In case of GUI, I specified the 'alternate source' path to the D drive's 'source/sxs folder but that failed without giving enough info. In case of the command prompt, here is what's happening: dism /online /enable-feature /featurename:NetFx3 /source:d:\sources\sxs I get error: Installed but Parent feature not enabled. So I tried another approached: dism /online /enable-feature /featurename:NetFx3 /all /source:d:\sources\sxs the above command, per http://blogs.technet.com/b/askcore/archive/2012/05/14/windows-8-and-net-framework-3-5.aspx is supposed to enable parent elements; but running this I get error like 'source not found'. Is there some error in my second command? What else I could do? This is Windows 2012 Server Standard edition. Thanks!

  • .NET 2.0 Application now running slow on IIS 7.5

    - by Valien
    I recently moved (and still in testing) an application from a Windows 2003 Server (Physical box) running IIS 6.x to a Windows 2008 R2 Standard (VM) IIS 7.5 server. The application is a .NET framework 2.0 application and is running under a 2.0 App Pool. This site works great except for one thing: Takes forever to get a request back. I've been tracking it with Chrome Inspect Element and it queries the site and can take up to 45 seconds to answer. Now when it does the page(s) render instantly but it's that initial request that's killing it. I see no error logs or issues with the application or Windows Event Viewer or even IIS logs so not sure where to start looking next. Some new changes was that previously the app resided behind a Pix firewall and now is behind a larger network environment in a DMZ zone (and I believe NetScaler is also being used to manage the network). I do not have rights/abilities to look at the network itself but can contact the Data center folks to look deeper into this but I wanted to make sure it's not my application that might be causing the slowdown or IIS. In summary: .NET 2.0 application works great in IIS 6.x Application moved to an IIS 7.5 server and now slow on rendering but when it does render responds back with pages instantly. Edit for solution Found out that it was the SOAP calls that were slowing the site down. In the new datacenter my application cannot request SOAP calls and so they time out after 40-45 seconds or so. Now trying to find out if I can install a proxy server to redirect this...

  • Ruby XMLRPC::CLIENT issue under Rails 2.3.5 with Ruby 1.8.6

    - by TallGreenTree
    I'm trying to implement a ping to an xmlrpc server written in PHP under CodeIgniter. The system currently works as expected when receiving pings from WordPress-based blogs, but I'm unable to generate a successful ping from Rails. The code I'm using to generate the ping is: server = XMLRPC::Client.new("digital466.local", "/schafercondoncarter/xmlrpc") result = server.call_async("ping", BLOG_CONFIG['title'], "http://digital466.local:3000") The code runs fine in Console, and retrieves a correctly formatted response from the server, but when I integrate the code into a rails observer or controller, I receive the following error message: Timeout::Error in PostsController#update execution expired RAILS_ROOT: /Users/digital466/Sites/sccblog Application Trace | Framework Trace | Full Trace /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/timeout.rb:60:in `rbuf_fill' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/protocol.rb:132:in `rbuf_fill' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/protocol.rb:116:in `readuntil' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/protocol.rb:126:in `readline' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:2020:in `read_status_line' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:2009:in `read_new' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:1050:in `request' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:992:in `post2' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/xmlrpc/client.rb:529:in `do_rpc' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:543:in `start' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/xmlrpc/client.rb:528:in `do_rpc' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/xmlrpc/client.rb:435:in `call2_async' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/xmlrpc/client.rb:425:in `call_async' /Users/digital466/Sites/sccblog/app/controllers/posts_controller.rb:89:in `update' Any assistance would be appreciated.
