• How to model has_many with polymorphism?

  - by Daniel Abrahamsson

  I've run into a situation that I am not quite sure how to model. Suppose I have a User class, and a user has many services. However, these services are quite different, for example a MailService and a BackupService, so single table inheritance won't do. Instead, I am thinking of using polymorphic associations together with an abstract base class: class User < ActiveRecord::Base has_many :services end class Service < ActiveRecord::Base validates_presence_of :user_id, :implementation_id, :implementation_type belongs_to :user belongs_to :implementation, :polymorphic = true delegate :common_service_method, :name, :to => :implementation end #Base class for service implementations class ServiceImplementation < ActiveRecord::Base validates_presence_of :user_id, :on => :create has_one :service, :as => :implementation has_one :user, :through => :service after_create :create_service_record #Tell Rails this class does not use a table. def self.abstract_class? true end #Default name implementation. def name self.class.name end protected #Sets up a service object def create_service_record service = Service.new(:user_id => user_id) service.implementation = self service.save! end end class MailService < ServiceImplementation #validations, etc... def common_service_method puts "MailService implementation of common service method" end end #Example usage MailService.create(..., :user_id => user.id) BackupService.create(...., :user_id => user.id) user.services.each do |s| puts "#{user.name} is using #{s.name}" end #Daniel is using MailService, Daniel is using BackupService So, is this the best solution? Or even a good one? How have you solved this kind of problem?

• GeoTrust SSL brand name used by re-sellers

  - by Christopher

  I feel like a I got the bait-and-switch from my web host provider since they advertise "GeoTrust SSL" for $99. I purchased it, thinking the certificate is issued from geotrust.com, but then I get an email from Comodo saying they are providing it. My host provider says they get a discount by using Comodo. I purchased the certificate with the understanding it would be issued by GeoTrust. I called the host provider and they said they usually expect it from GeoTrust, but someone from email support responded saying the product name is "GeoTrust SSL" but they use Comodo to get a discount. I think this is bogus and unfair trade practice. However, searching for "GeoTrust" on google brings up a ton of websites selling "GeoTrust" certificates. How can companies get away with this? Since the host provider is part of BBB I plan to inform my host to update the purchase page on their website to state clearly that... "This certicate is provided at a discount and may be issued by a provider other than GeoTrust.com, such as Comodo.com" Any feedback on this is appreciated.

• Introduction to WebCenter Personalization: &ldquo;The Conductor&rdquo;

  - by Steve Pepper

  There are some new faces in the town of WebCenter with the latest 11g PS3 release.  A new component has introduced itself as "Oracle WebCenter Personalization", a.k.a WCP, to simplify delivery of a personalized experience and content to end users.  This posting reviews one of the primary components within WCP: "The Conductor". The Conductor: This ain't just an ordinary cloud... One of the founding principals behind WebCenter Personalization was to provide an open client-side API that remains independent of the technology invoking it, in addition to independence from the architecture running it.  The Conductor delivers this, and much, much more. The Conductor is the engine behind WebCenter Personalization that allows flow-based documents, called "Scenarios", to be managed and executed on the server-side through a well published and RESTful api.      The Conductor also supports an extensible model for custom provider integration that can be easily invoked within a Scenario to promote seamless integration with existing business assets. Introducing the Scenario Conductor Scenarios are declarative offline-authored documents using the custom Personalization JDeveloper bundle included with WebCenter.  A Scenario contains one (or more) statements that can: Create variables that are scoped to the current execution context Iterate over collections, or loop until a specific condition is met Execute one or more statements when a condition is met Invoke other scenarios that exist within the same namespace Invoke a data provider that integrates with custom applications Once a variable is assigned within the Scenario's execution context, it can be referenced anywhere within the same Scenario using the common Expression Language syntax used in J2EE web containers. Scenarios are then published and tested to the Integrated WebLogic Server domain, or published remotely to other domains running WebCenter Personalization. Various Client-side Models The Conductor server API is built upon RESTful services that support a wide variety of clients able to communicate over HTTP.  The Conductor supports the following client-side models: REST:  Popular browser-based languages can be used to manage and execute Conductor Scenarios.  There are other public methods to retrieve configured provider metadata that can be used by custom applications. The Conductor currently supports XML and JSON for it's API syntax. Java: WebCenter Personalization delivers a robust and light-weight java client with the popular Jersey framework as it's foundation.  It has never been easier to write a remote java client to manage remote RESTful services. Expression Language (EL): Allow the results of Scenario execution to control your user interface or embed personalized content using the session-scoped managed bean.  The EL client can also be used in straight JSP pages with minimal configuration. Extensible Provider Framework The Conductor supports a pluggable provider framework for integrating custom code with Scenario execution.  There are two types of providers supported by the Conductor: Function Provider: Function Providers are simple java annotated classes with static methods that are meant to be served as utilities.  Some common uses would include: object creation or instantiation, data transformation, and the like.  Function Providers can be invoked using the common EL syntax from variable assignments, conditions, and loops. For example:  ${myUtilityClass:doStuff(arg1,arg2))} If you are familiar with EL Functions, Function Providers are based on the same concept. Data Provider: Like Function Providers, Data Providers are annotated java classes, but they must adhere to a much more strict object model.  Data Providers have access to a wealth of Conductor services, such as: Access to namespace-scoped configuration API that can be managed by Oracle Enterprise Manager, Scenario execution context for expression resolution, and more.  Oracle ships with three out-of-the-box data providers that supports integration with: Standardized Content Servers(CMIS),  Federated Profile Properties through the Properties Service, and WebCenter Activity Graph. Useful References If you are looking to immediately get started writing your own application using WebCenter Personalization Services, you will find the following references helpful in getting you on your way: Personalizing WebCenter Applications Authoring Personalized Scenarios in JDeveloper Using Personalization APIs Externally Implementing and Calling Function Providers Implementing and Calling Data Providers

• How to Resolve a Transformation Service with BRE that occurs after an Orchestration in an Itinerary?

  - by Maxime Labelle

  In trying to implement simple integration patterns with Biztalk ESB Toolkit 2.0, I'm facing a problem trying to resolve a Transformation Itinerary Service that occurs after an Orchestration. I'm using the BRE Resolver to execute rules that need to inspect the Context Message Type property to determine the appropriate map to use. However, once the message reaches the step in the Itinerary associated with the Transformation Service, the map fails to execute. From careful investigation, it appears that the message type is not supplied to the "Resolution" object that is used internally by the BRE resolver. Indeed, since the message leaving the preceding Orchestration is typed System.Xml.XmlDocument, the type of the message is "demoted" from the context. By tracking rules engine execution, I can observe that the type of the message is indeed lost when reaching the BRE resolver. The type of the message is empty, whereas the strongly-typed of the document is Microsoft.XLANGs.BaseTypes.Any. The Orchestration service that I use is taken straight from the samples that ship with ESB Toolkit 2.0. Is there a way to perform Context-Based BRE resolution after an Orchestration in an Itinerary?

• How do you keep SOA DRY?

  - by TaylorOtwell

  In our organization, we've shifted to a more "service oriented architecture". To give an example, let's assume we need to retrieve a "Quote" object. This quote has a shipper, a consignee, phone numbers, contacts, email addresses, and other location information. In other words, a Quote object is made up of many other objects. So, it seems like it would make sense to make a "Quote Retrieval Service". In our situation, we've accomplished this by creating a .NET solution and writing the service. The service API looks something like this (in pseudo-code): Function GetQuote(String ID) Returns Quote So, so far so good. Now, when this service is consumed, to keep things "de-coupled", we are creating essentially a duplicate of the Quote object and mapping from the QuoteService version of the Quote into the consumer's version of the Quote. In many cases, these classes will have the exact same properties. So, if the Quote service is consumed by 5 other applications, we would have 6 definitions of what a "Quote" is. One for each consumer, and one for the service. This feels wrong. I thought code was supposed to be DRY, but it seems like our method of SOA is forcing us to create tons of duplicated class definitions. What are we doing wrong, or is the code duplication just a "necessary evil" of SOA?

• Constituent Experience Counts In Public Sector

  - by Michael Seback

    Businesses and government organizations are operating in an era of the empowered customer where service  and communication channels are challenged every day.  Consumers in the private sector have high expectations from purchasing gifts online, reading reviews on social sites, and expecting the companies they do business with to know and reward them.   In the Public Sector, constituents also expect government organizations to provide consistent and timely service across agencies and touch points.  Examples include requesting critical city services, applying for social assistance or reviewing insurance plans for a health insurance exchange. If an individual does not receive the services they need at the right time and place, it can create a dire situation – involving housing, food or healthcare assistance. Government organizations need to deliver a fast, reliable and personalized experience to constituents. Look at a few recent statistics from a Government focused survey: How do you define good customer service? 70 % improved services, 48% shortest time to provide information, 44% shortest time to resolve complaints What are ways/opportunities to improve customer service? 69% increased collaboration across agencies and 41% increased customer service channels Are you using data collected to make informed decisionsto improve customer service efforts? 39% data collection is limited, not used to improve decision making Source: Re-Imagining Customer Service in Government, 2012 Click here to see the highlights.  Would you like to get started – read Eight Steps to great constituent experiences for government.

• Solving &ldquo;XmlSchemaException: The global element '&lt;elementName&gt;' has already been declare

  - by ChrisD

  I recently encountered this error when I attempted to consume a new hosted WCF service.  The service used the Request/Response model and had been properly decorated.  The response and request objects were marked as DataContracts and had a specified namespace.   My WCF service interface was marked as a ServiceContract and shared the namespace attribute value.   Everything should have been fine, right? [ServiceContract(Namespace = "http://schemas.myclient.com/09/12")] public interface IProductActivationService { [OperationContract] ActivateSoftwareResponse ActivateSoftware(ActivateSoftwareRequest request); } well, not exactly.  Apparently the WSDL generator was having an issue: System.Xml.Schema.XmlSchemaException: The global element 'http://schemas.myclient.com/09/12:ActivateSoftwareResponse' has already been declared. After digging I’ve found the problem; the WSDL generator has some reserved suffixes for its entities, including Response, Request, Solicit (see http://msdn.microsoft.com/en-us/library/ms731045.aspx).  The error message is actually the result of a naming conflict.  The WSDL generator uses the namespace of the service to build its reserved types.  The service contract and data contract share a namespace, which coupled with the response/request name suffixes I was using in my class names, resulted in the SchemaException. The Fix: Two options: Rename my data contract entities to use a non-reserved keyword suffix (i.e.  change ActivateSoftwareResponse to ActivateSoftwareResp). or; Change the namespace of the data contracts to differ from the service contract namespace. I chose option 2 and changed all my data contracts to use a “http://schemas.myclient.com/09/12/data” namespace value. This avoided a name collision and I was able to produce my WSDL and consume my service.

• Exposing a service to external systems - How should I design the contract?

  - by Larsi

  Hi! I know this question is been asked before here but still I'm not sure what to select. My service will be called from many 3 party system in the enterprise. I'm almost sure the information the service will collect (MyBigClassWithAllInfo) will change during the products lifetime. Is it still a good idea to expose objects? This is basically what my two alternatives: [ServiceContract] public interface ICollectStuffService { [OperationContract] SetDataResponseMsg SetData(SetDataRequestMsg dataRequestMsg); } // Alternative 1: Put all data inside a xml file [DataContract] public class SetDataRequestMsg { [DataMember] public string Body { get; set; } [DataMember] public string OtherPropertiesThatMightBeHandy { get; set; } // ?? } // Alternative 2: Expose the objects [DataContract] public class SetDataRequestMsg { [DataMember] public Header Header { get; set; } [DataMember] public MyBigClassWithAllInfo ExposedObject { get; set; } } public class SetDataResponseMsg { [DataMember] public ServiceError Error { get; set; } } The xml file would look like this: <?xml version="1.0" encoding="utf-8"?> <Message>   <Header>     <InfoAboutTheSender>...</InfoAboutTheSender>   </Header>   <StuffToCollectWithAllTheInfo>   <stuff1>...</stuff1> </StuffToCollectWithAllTheInfo> </Message> Any thought on how this service should be implemented? Thanks Larsi

• Accessing Secure Web Services from ADF Mobile

  - by Shay Shmeltzer

  Most of the enterprise Web services you'll access are going to be secured - meaning they'll require you to pass a user/password in order to get to their data.  If you never created a secured Web service, it's simple in JDeveloper! For the below video I just right clicked on a Java class that I exposed as a Web service, and chose  "Web Service Properties" and then checked the "oracle/wss_username_token_service_policy" box from the list of options (that's the option supported by ADF Mobile right now): In the demo below we are going to use a "remote" login server that does the authentication of the user/pass.The easiest way to "create" a remote login server is to create a "regular" web ADF application, secure it, and deploy it on a server. The secured ADF application can just require ADF Authentication with a simple HTTP Basic Authentication - basically the next two images in the Application->Secure->Configure ADF Security menu wizard. ok - so now you have a secured ADF application - deploy it on a server and get the URL for that application.  From this point on you'll see the process in the video which deals with the configuration of your ADF Mobile app. First you'll need to enable security for your ADF mobile application, so it will prompt users to provide a user/pass combination. You'll also need to configure security on specific features. And you can have them use remote login pointing to your regular secured ADF application. Next define your Web service data control. Right click on the web service data control to "define Web Service Security". You'll also need to define the adfCredentialStoreKey property for the Web Service data control in the connections.xml file. This should be it. Here is the flow: If you haven't already - you can read more about this in the Mobile developer guide, and Andrejus has a sample for you.

• Why does a change of Session State provider lead to an ASPx page yielding garbage?

  - by Rory Becker

  I have an aspnet webapp which has worked very well up until now. I was recently asked to explore ways of making it scale better. I found that seperation of database and Webapp would help. Further I was told that if I changed my session providing mechanism to SQLServer, I would be able to duplicate the Web Stack to several machines which could each call back to the state server allowing the load to be distirbuted better. This sounds logical. So I created an ASPState database using ASPNet_RegSQL.exe as detailed in many locations across the web and changed the web.config on my app from: <sessionState mode="InProc" cookieless="false" timeout="20" /> To: <sessionState mode="SQLServer" sqlConnectionString="Server=SomeSQLServer;user=SomeUser;password=SomePassword" cookieless="false" timeout="20" /> Then I addressed my app, which presented me with its logon screen and I duly logged in. Once in I was presented, not with the page I was expecting, but with: I can change the sessionstate back and forth. This problem goes away and then comes back based on which set of configuration I use. Why is this happening?

• Question about the evolution of interaction paradigm between web server program and content provider program?

  - by smwikipedia

  Hi experts, In my opinion, web server is responsible to deliver content to client. If it is static content like pictures and static html document, web server just deliver them as bitstream directly. If it is some dynamic content that is generated during processing client's request, the web server will not generate the conetnt itself but call some external proram to genearte the content. AFAIK, this kind of dynamice content generation technologies include the following: CGI ISAPI ... And from here, I noticed that: ...In IIS 7, modules replace ISAPI filters... Is there any others? Could anyone help me complete the above list and elabrate on or show some links to their evolution? I think it would be very helpful to understand application such as IIS, TomCat, and Apache. I once wrote a small CGI program, and though it serves as a content generator, it is still nothing but a normal standalone program. I call it normal because the CGI program has a main() entry point. But with the recenetly technology like ASP.NET, I am not writing complete program, but only some class library. Why does such radical change happens? Many thanks.

• How to handle fine grained field-based ACL permissions in a RESTful service?

  - by Jason McClellan

  I've been trying to design a RESTful API and have had most of my questions answered, but there is one aspect of permissions that I'm struggling with. Different roles may have different permissions and different representations of a resource. For example, an Admin or the user himself may see more fields in his own User representation vs another less-privileged user. This is achieved simply by changing the representation on the backend, ie: deciding whether or not to include those fields. Additionally, some actions may be taken on a resource by some users and not by others. This is achieved by deciding whether or not to include those action items as links, eg: edit and delete links. A user who does not have edit permissions will not have an edit link. That covers nearly all of my permission use cases, but there is one that I've not quite figured out. There are some scenarios whereby for a given representation of an object, all fields are visible for two or more roles, but only a subset of those roles my edit certain fields. An example: { "person": { "id": 1, "name": "Bob", "age": 25, "occupation": "software developer", "phone": "555-555-5555", "description": "Could use some sunlight.." } } Given 3 users: an Admin, a regular User, and Bob himself (also a regular User), I need to be able to convey to the front end that: Admins may edit all fields, Bob himself may edit all fields, but a regular User, while they can view all fields, can only edit the description field. I certainly don't want the client to have to make the determination (or even, for that matter, to have any notion of the roles involved) but I do need a way for the backend to convey to the client which fields are editable. I can't simply use a combination of representation (the fields returned for viewing) and links (whether or not an edit link is availble) in this scenario since it's more finely grained. Has anyone solved this elegantly without adding the logic directly to the client?

• Spring MVC: should service layer be returning operation specific DTO's ?

  - by arrages

  In my Spring MVC application I am using DTO in the presentation layer in order to encapsulate the domain model in the service layer. The DTO's are being used as the spring form backing objects. hence my services look something like this: userService.storeUser(NewUserRequestDTO req); The service layer will translate DTO - Domain object and do the rest of the work. Now my problem is that when I want to retrieve a DTO from the service to perform say an Update or Display I can't seem to find a better way to do it then to have multiple methods for the lookup that return different DTO's like... EditUserRequestDTO userService.loadUserForEdit(int id); DisplayUserDTO userService.loadUserForDisplay(int id); but something does not feel right about this approach. The reason do have separate DTO's is that DisplayUserDTO is strongly typed to be read only and also there are many properties of user that are entities from a lookup table in the db (like city and state) so the DisplayUserDTO would have the string description of the properties while the EditUserRequestDTO will have the id's that will back the select drop down lists in the forms. What do you think? thanks

• How do you program a windows service in C# to start an application for a user?

  - by Swoop

  Is it possible to start a program so that it is available to a user with a windows service? I have been working with the Process.Start() in C#. I can get the service to kickoff some sort of process that appears in the Task Manager list under processes. However, the program nevers appears on the screen. By default, it runs under the user name "SYSTEM". I have adjusted the "Log On" option in the service manager to match the person logged into the computer, but this does not cause a window to appear either. I feel like I am either missing a simple setting, or need to take a different direction for this. Below is the code I have been working with to start up Firefox as a test app. private void startRunDap() { ProcessStartInfo startInfo = new ProcessStartInfo(); startInfo.FileName = "Firefox"; startInfo.WindowStyle = ProcessWindowStyle.Normal; startInfo.UseShellExecute = true; Process.Start(startInfo); //Process.Start("Firefox"); }

• supervise/daemontools conflicts with apache -D FOREGROUND

  - by Kevin G.

  Hoping that somebody can help us understand this behavior. We've got a bunch of daemontools services under /etc/service/. One of the services controls apache, and the run script has this in it. exec envdir /var/lib/supervise/wwwproxy/env setuidgid root bash <<-BASH ulimit -n 8192 # also increase the running user's file descriptor limit exec apache2 -f /path/to/demo_apache2.conf -D FOREGROUND BASH We were having the problem that svc -d /etc/service/* actually had the effect of restarting all the services, it didn't take them down. We finally tracked it down to that one service, and found that svc -d /etc/service/apache2 would bring up any other service was down, including itself. Changing FOREGROUND to NO_DAEMONIZE fixes the behavior, but we'd really like to understand what's going on. Can anybody explain why an svc -d on one service would bring an other service up? Thanks for any clue you can offer.

• Why notify listeners in a content provider query method?

  Vegeolla has this blog post about content providers and the snippet below (at the bottom) with this line: cursor.setNotificationUri(getContext().getContentResolver(), uri); I'm curious as to why one would want to notify listeners about a query operation. Am I missing something? Thanks @Override public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) { // Uisng SQLiteQueryBuilder instead of query() method SQLiteQueryBuilder queryBuilder = new SQLiteQueryBuilder(); // Check if the caller has requested a column which does not exists checkColumns(projection); // Set the table queryBuilder.setTables(TodoTable.TABLE_TODO); int uriType = sURIMatcher.match(uri); switch (uriType) { case TODOS: break; case TODO_ID: // Adding the ID to the original query queryBuilder.appendWhere(TodoTable.COLUMN_ID + "=" + uri.getLastPathSegment()); break; default: throw new IllegalArgumentException("Unknown URI: " + uri); } SQLiteDatabase db = database.getWritableDatabase(); Cursor cursor = queryBuilder.query(db, projection, selection, selectionArgs, null, null, sortOrder); // Make sure that potential listeners are getting notified cursor.setNotificationUri(getContext().getContentResolver(), uri); return cursor; }

• How do I consume a self hosted WCF service with Compact Framework client?

  - by pitprog

  Hello - I've been trying to figure out how to consume a self hosted WCF service from a Windows CE device. I've not found any good resources that walk through this process online. I've found some good samples for self hosting, and that part seems to be working fine, but not sure how to go about consuming on the compact framework. In the past I was able to use NetCFSvcUtil.exe, but this doesn't seem to work with a self hosted service. NetCFSvcutil says: The underlying connection was closed: An unexpected error occurred on a receive. Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. I've used Jason Henderson's sample http://www.codeproject.com/KB/WCF/WCFexample.aspx to get started with self hosting and that part works as expected. Can any one point me to a sample where a compact framework client is used to consume a self hosted WCF service? or give a brief explanation of how I create the plumbing on the compact framework side? For the host application I'm using a WinForm .Net 3.5 project and for the client a WinForm Compact Framework 3.5 project. Thanks!

• Is there a free version control server provider for non-public projects?

  - by ttobiass

  I'd like to have a version control server (preferably SVN) accessible on the internet without having to host my own (linux) server. Setting up a home server ala DynDNS is not really an option. Can you have non-public (maybe single-user) projects on one of the OSS project hosting sites? Or are there alternatives? I had a look at Google Code. But that looked very public to me. Any help would be greatly appreciated :-)

  I have a python based server which i start from the terminal. This particular instance of the terminal then gives control to the program, and the program uses it as a kind of logging window, until its closed. Is this normal, or should i somehow try to start the program some other way in which it will simply show as an active process? If i close the terminal from which i started the program, the program dies with it. Thank you

• Objective-C memory management issue

  - by Toby Wilson

  I've created a graphing application that calls a web service. The user can zoom & move around the graph, and the program occasionally makes a decision to call the web service for more data accordingly. This is achieved by the following process: The graph has a render loop which constantly renders the graph, and some decision logic which adds web service call information to a stack. A seperate thread takes the most recent web service call information from the stack, and uses it to make the web service call. The other objects on the stack get binned. The idea of this is to reduce the number of web service calls to only those appropriate, and only one at a time. Right, with the long story out of the way (for which I apologise), here is my memory management problem: The graph has persistant (and suitably locked) NSDate* objects for the currently displayed start & end times of the graph. These are passed into the initialisers for my web service request objects. The web service call objects then retain the dates. After the web service calls have been made (or binned if they were out of date), they release the NSDate*. The graph itself releases and reallocates new NSDates* on the 'touches ended' event. If there is only one web service call object on the stack when removeAllObjects is called, EXC_BAD_ACCESS occurs in the web service call object's deallocation method when it attempts to release the date objects (even though they appear to exist and are in scope in the debugger). If, however, I comment out the release messages from the destructor, no memory leak occurs for one object on the stack being released, but memory leaks occur if there are more than one object on the stack. I have absolutely no idea what is going wrong. It doesn't make a difference what storage symantics I use for the web service call objects dates as they are assigned in the initialiser and then only read (so for correctness' sake are set to readonly). It also doesn't seem to make a difference if I retain or copy the dates in the initialiser (though anything else obviously falls out of scope or is unwantedly released elsewhere and causes a crash). I'm sorry this explanation is long winded, I hope it's sufficiently clear but I'm not gambling on that either I'm afraid. Major big thanks to anyone that can help, even suggest anything I may have missed?
