  • Passing Auth to API calls with Web Service References

    - by coffeeaddict
    I am new to web services. The last time I dealt with SOAP was when I created a bunch of wrapper classes that sent requests and received responses back per some response objects/classes I had created. So I had an object to send certain API requests and likewise a set of objects to hold the response back as an object so I could utilize that 3rd party API. Then someone came to me and said why not just use the wsdl and a web service. Ok, so today I went and created a "Service Reference". I see that this is what's called a "Proxy Class". You just instantiate an instance of this and then walla you have access to all the methods from the wsdl. But this leaves me with auth questions. Back when I created my own classes manually, I had a class which exposed properties that I would set then access for things like signature, username, password that got sent along with the Http request that were required by whatever 3rd party API I was using to make API calls. But then with using a Service Reference, how then would I pass this information just like I had done in my custom classes? For instance I'm going to be working with the PayPal API. It requires you to send a signature and a few other pieces of information like username and password. // Determins if API call needs to use a session based URI string requestURI = UseAuthURI == true ? _requestURIAuthBased + aSessionID : _requestURI; byte[] data = XmlUtil.DocumentToBytes(doc); // Create the atual Request instance HttpWebRequest request = CreateWebRequest(requestURI, data.Length); So how do I pass username, password, signature, etc. when using web service references for each method call? Is it as simple as specifying it as a param to the method or do you use the .Credentials and .URL methods of your proxy class object? It seems to me Credentials means windows credentials but I could be wrong. Is it limited to that or can you use that to specify those required header values that PayPal expects with each method call/API request?

    - by sathya
    Am using google app engine with eclipse IDE and trying to upload a audio file. I used the File Upload in Google App Engine For Java and can able to upload the file successfully. Now am planning to use REST web service for it. I had analyzed in developers.google but i failed. Can anyone suggest me how to implement REST Web services in google app engine using Eclipse. The code google provided is shown below, // file Upload.java public class Upload extends HttpServlet { private BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException { Map<String, BlobKey> blobs = blobstoreService.getUploadedBlobs(req); BlobKey blobKey = blobs.get("myFile"); if (blobKey == null) { res.sendRedirect("/"); } else { res.sendRedirect("/serve?blob-key=" + blobKey.getKeyString()); }}} // file Serve.java public class Serve extends HttpServlet { private BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException { BlobKey blobKey = new BlobKey(req.getParameter("blob-key")); blobstoreService.serve(blobKey, res); }} // file index.jsp <%@ page import="com.google.appengine.api.blobstore.BlobstoreServiceFactory" %> <%@ page import="com.google.appengine.api.blobstore.BlobstoreService" %> <% BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); %> <form action="<%= blobstoreService.createUploadUrl("/upload") %>" method="post" enctype="multipart/form-data"> <input type="file" name="myFile"> <input type="submit" value="Submit"> </form> // web.xml <servlet> <servlet-name>Upload</servlet-name> <servlet-class>Upload</servlet-class> </servlet> <servlet> <servlet-name>Serve</servlet-name> <servlet-class>Serve</servlet-class> </servlet> <servlet-mapping> <servlet-name>Upload</servlet-name> <url-pattern>/upload</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>Serve</servlet-name> <url-pattern>/serve</url-pattern> </servlet-mapping> Now how to provide a rest web service for the above code.

  • Secure WS client with UsernameToken(SOAP security header)

    - by user79163
    Hi, I'm trying to secure my WS client to be able to call the WS. My code looks like this: SendSmsService smsService = new SendSmsService(); SendSms sendSMS = smsService.getSendSms(); BindingProvider stub = (BindingProvider)sendSMS; //Override endpoint with local copy of wsdl. String URL ="";//here is the wsdl url Map<String,Object> requestContext = stub.getRequestContext(); requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, URL); //Set usernametoken URL fileURL = loader.getResource("client-config.xml"); File file = new File(fileURL.getFile()); FileInputStream clientConfig = null; try { clientConfig = new FileInputStream(file); } catch (FileNotFoundException e) { e.printStackTrace(); } XWSSecurityConfiguration config = null; try { config = SecurityConfigurationFactory.newXWSSecurityConfiguration(clientConfig); } catch (Exception e) { e.printStackTrace(); log.warn("Exception: "+e.getMessage()); } requestContext.put(XWSSecurityConfiguration.MESSAGE_SECURITY_CONFIGURATION, config); //Invoke the web service String requestId = null; try { requestId = sendSMS.sendSms(addresses, senderName, charging, message, receiptRequest); } catch (PolicyException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (ServiceException e) { // TODO Auto-generated catch block e.printStackTrace(); } and the config file looks like this: <xwss:JAXRPCSecurity xmlns:xwss="http://java.sun.com/xml/ns/xwss/config" optimize="true"> <xwss:Service> <xwss:SecurityConfiguration dumpMessages="true" xmlns:xwss="http://java.sun.com/xml/ns/xwss/config"> <xwss:UsernameToken name="username" password="password> </xwss:SecurityConfiguration> </xwss:Service> <xwss:SecurityEnvironmentHandler> util.SecurityEnvironmentHandler </xwss:SecurityEnvironmentHandler> </xwss:JAXRPCSecurity> The SecurityEnviromentHandler is a dummy class that implements javax.security.auth.callback.CallbackHandler. Authentication must be in compliance with Oasis Web Services Security Username Token Profile 1.0. But I'm constantly getting "Security header not valid" error. Where am I going wrong, can anyone tell me. I used wsimport(JAX_WS 2.1 to generate classes for my client) Note:Only thing I know about this WS is WSDL URL and user&pass for authentication

  • Best Method to SFTP or FTPS Files via SSIS

    - by Registered User
    What is the best method using SSIS (SQL Server Integration Services) to upload a file to either a remote SFTP (secure FTP with SSH2 protocal) or FTPS (FTP over SSL) site? I've used the following methods, but each has short-comings I would like to avoid: COZYROC LIBRARY Method: Install the CozyRoc library on each development and production server and use the SFTP task to upload the files. Pros: Easy to use. It looks, smells, and feels like a normal SSIS task. SSIS also recognizes the password as sensitive information and allows you all the normal options for protecting the sensitive information instead of just storing it in clear text in a non-secure manner. Works well with other SSIS tasks such as ForEach Loop Containers. Errors out when uploads and downloads fail. Works well when you don't know the names of the files on the remote FTP site to download or when you won't know the name of the file to upload until run-time. Cons: Costs money to license in a production environment. Makes you dependent upon the vendor to update their libraries between each version. Although they already have a 2008 version, this caused me a problem during the CTP's of 2008. Requires installing the libraries on each development and production machine. COMMAND LINE SFTP PROGRAM Method: Install a free command-line SFTP application such as Putty and execute it either by running a batch file or operating system process task. Pros: Free, free, and free. You can be sure it is secure if you are using Putty since numerous GUI FTP clients appear to use Putty under the covers. You DEFINATELY know you are using SSH2 and not SSH. Cons: The two command-line utilities I tried (Putty and Cygwin) required storing the SFTP password in a non-secure location. I haven't found a good way to capture failures or errors when uploading files. The process doesn't look and smell like SSIS. Most of the code is encapsulated in text files instead of SSIS itself. Difficult to use if you don't know the exact name of the file you are uploading or downloading. A 3RD PARTY C# or VB.NET LIBRARY Method: Install a SFTP or FTPS library and use a Script Task that references the library to upload the files. (I've never tried this, so I'm going to guess at the pros and cons) Pros: Probably easy to capture errors. Should work well with variables, so it would probably be easy to use even when you don't know the exact name of the file you are uploading or downloading. Cons: It's a script task combined with .NET libraries. If you are using SSIS, then you probably are more comfortable with SSIS tasks then .NET code. Script tasks are also difficult to troubleshoot since they don't have the same debugging tools and features as regular .NET projects. Creates a dependency on 3rd party code that may not work between different versions of SQL Server. To be fair, it is probably MORE likely to work between different versions of SQL Server than a 3rd party SSIS task library. Another huge con -- I haven't found a free C# or VB.NET library that does this as of yet. So if anyone knows of one, then please let me know!

  • Getting a null reference exception exporting a slightly complex rdlc report to excel

    - by George Handlin
    Have an issue in exporting a slightly complex report to excel from an rdlc. Exporting a simple tabular report works fine, but getting a null reference exception with a more complex one. As is usually the case, it works on the server in the development environment, but not in the test environment. The server in the development environment has iis, sql and sql reporting services on it and test only has iis (I didn't set them up). I'm guessing there is something that gets installed with SSRS that is not installed with just the report viewer. The report has several parameters going into it and a few generic lists going in for datasources. Some tables for display as well as a list. Working with the 2005 version.

  • L2S DataContext out of synch: row not found or changed

    - by awrigley
    The Problem I am getting a number of errors that imply that the DataContext, or rather, the way I am using the DataContext is getting out of synch. The error occurs on db.SubmitChanges() where db is my DataContext instance. The error is: Row not found or changed. The problem only occurs intermitently, for example, adding a row then deleting it. If I stop the dev server and restart, the added row is there and I can delete it no problem. Ie, it seems that the problem is related to the DataContext losing track of the rows that have been added. IMPORTANT: Before anyone votes to close this thread, on the basis of it being a duplicate, I have checked the sql server profiler and there is no "Where 0 = 1" in the SQL. I have also recreated the dbml file, so am satisfied that the database schema is in synch with the schema represented by the dbml file. Ie, no cases of mismatched nullable/not nullable columns, etc. My Diagnosis (for what it is worth): It seems to be a problem related to how I am using the DataContext. I am new to MVC, Repositories and Services patterns, so suspect that I have wired things up wrong. The Setup Simple eLearning app in its early stages. Pupils need to be able to add and delete courses (Courses table) to their UserCourses. To do this, I have a service that gets a specific DataContext instance Dependency Injected into its constructor. Service Class Constructor: public class SqlPupilBlockService : IPupilBlockService { DataContext db; public SqlPupilBlockService(DataContext db) { this.db = db; CoursesRepository = new SqlRepository<Course>(db); UserCoursesRepository = new SqlRepository<UserCourse>(db); } // Etc, etc } The CoursesRepository and UserCoursesRepository are both private properties of the service class that are of Type IRepository (just a simple generic repository interface). Sql Respoitory Code: public class SqlRepository<T> : IRepository<T> where T : class { DataContext db; public SqlRepository(DataContext db) { this.db = db; } #region IRepository<T> Members public IQueryable<T> Query { get { return db.GetTable<T>(); } } public List<T> FetchAll() { return Query.ToList(); } public void Add(T entity) { db.GetTable<T>().InsertOnSubmit(entity); } public void Delete(T entity) { db.GetTable<T>().DeleteOnSubmit(entity); } public void Save() { db.SubmitChanges(); } #endregion } The two methods for adding and deleting UserCourses are: Service Methods for Adding and Deleting UserCourses: public void AddUserCourse(int courseId) { UserCourse uc = new UserCourse(); uc.IdCourse = courseId; uc.IdUser = UserId; uc.DateCreated = DateTime.Now; uc.DateAmended = DateTime.Now; uc.Role = "Pupil"; uc.CourseNotes = string.Empty; uc.ActiveStepIndex = 0; UserCoursesRepository.Add(uc); UserCoursesRepository.Save(); } public void DeleteUserCourse(int courseId) { var uc = (UserCoursesRepository.Query.Where(x => x.IdUser == UserId && x.IdCourse == courseId)).Single(); UserCoursesRepository.Delete(uc); UserCoursesRepository.Save(); } Ajax I am using Ajax via Ajax.BeginForm I don't think that is relevant. ASP.NET MVC 3 I am using mvc3, but don't think that is relevant: the errors are related to model code.

  • SSRS 2008 printing single page renders different for print

    - by user270437
    I have a problem with SSRS 2008 reports rendering differently on the reporting server than the way it renders when you print the report. I’m trying to figure out to print a single page and have the print show that same records as I see on the report on the screen. As a test, I created a simple report with no headers or footers and just added a Tablix table to display the records (no groupings). My data set for this test displays 2 ¼ pages of records when I deploy it to our reporting services server and run it. If I click the print Icon and preview the report is 2 ¾ pages. I haven’t found anything searching on this so it makes me think it is something simple I’m missing. A basically want the report to render the same records on each page in Report Manager as it does when it prints, how do I accomplish this? (In response to answer posted by Chris)…If that is the case then it is disappointing. Customers are accustomed to WYSIWYG and will have a hard time understanding that, I imagine we will be getting a lot of support calls. This still leaves an issue. I tried using print preview and could not find any way to single out a page. If I select a page up front to print, or preview it renders different so I get different records. And if I preview the entire document, I can only print the entire document. You mentioned the Excel render; we have customers that will want that also. The problem I have found with Excel exports is that even a basic report winds up merging some cells and that messes up sorting. I’m going to try your tip about grouping to see if I can get a clean export to a page. It would have been nice if they would have created a property for certain controls like the tablix table called “ExcelSheet”. Then all you would have to do is give it a name and it would create a new sheet for each control with a name, the name becoming the sheet title. Thanks for the information you supplied it is very useful as I’m new to SSRS. If you know how I can Preview in print render and select individual pages to print from the render let me know. Update 02/19/2010 After testing this more I now realize it is just a bad design of Report managers print driver or a limitation because it is server based. The options work differently than Windows apps drivers, But I did find a work around. Here is the test I performed comparing Excel to Report Manager. I bring up a report that will render more than 1 page when printed. I then export to Excel, in Excel I select print preview. I can navigate the pages in preview and then select a single page like page 3. I can then print just page 3 without leaving print preview and it prints just like it rendered. I cannot do this using print in report manager. If I select print preview in report manager then try to print while in preview it always prints the entire document. However if I close out of print preview, I can then select page 3 and print it as rendered. It is just one additional step once you know what to do, but it took some time to figure it out.

Topics Ian covers include the dynamic keyword in C# 4, the AutomationFactory class, the API to check if you are in a trusted application, and communicating with Excel. Module 8 – Advanced Out of Browser and MEF Click here to visit this module. This hands-on lab walks through the creation of a trusted out of browser application and the new functionality that comes with that. You will learn to use COM Automation, handle the window closing event, set custom window chrome, digitally sign your Silverlight out of browser trusted application, create a silent install option, and take advantage of MEF. Link Download Source Download Lab Document Videos Module 8.1 – Custom Window Chrome for Elevated Trust Out of Browser Applications Ian Griffiths discusses how to replace the standard operating system window chrome with customized chrome for an elevated trusted out of browser application. He covers how it is important to handle close, resize, minimize, and maximize events. Ian mentions that the tooling was not ready when he shot this video, but the good news is that the tooling now supports setting the custom chrome directly from the property page for the Silverlight application. Module 8.2 – Window Closing Event for Out of Browser Applications Ian Griffiths discusses the WindowClosing event and how to handle and optionally cancel the event. Module 8.3 – Silent Install of Out of Browser Applications Ian Griffiths discusses how to use the SLLauncher executable to install an out of browser application. He discusses the optional command line switches that can be set including how the emulate switch can help you emulate the install process. Ian also shows how to setup a shortcut for the application and tell the application where it should look for future updates online. Module 8.4 – Digitally Signing Out of Browser Application Ian Griffiths discusses how and why to digitally sign an out of browser application using the signtool program. He covers what trusted certificates are, the implications of signing (or not signing), and the effect on the user experience. Module 8.5 – The Value of MEF with Silverlight Ian Griffiths discusses what MEF is, how your application can benefit from it, and the fundamental features it puts at your disposal. He covers the 3 step import, export and compose process as well as how to dynamically import XAP files using MEF. Summary As you can probably tell from the long list above – this series contains a ton of great content, and hopefully provides a nice end-to-end walkthrough that helps explain how to take advantage of Silverlight 4 (and all its new features).  Hope this helps, Scott

  • Red Hat cluster: Failure of one of two services sharing the same virtual IP tears down IP

    - by js01
    I'm creating a 2+1 failover cluster under Red Hat 5.5 with 4 services of which 2 have to run on the same node, sharing the same virtual IP address. One of the services on each node needs a (SAN) disk, the other doesn't. I'm using HA-LVM. When I shut down (via ifdown) the two interfaces connected to the SAN to simulate SAN failure, the service needing the disk is disabled, the other keeps running, as expected. Surprisingly (and unfortunately), the virtual IP address shared by the two services on the same machine is also removed, rendering the still-running service useless. How can I configure the cluster to keep the IP address up?

    - by mbridge
    What do you need first? Please download SQL Server® 2008 R2 November CTP Reporting Services Add-in for Microsoft SharePoint® Technologies 2010 and please follow this steps: 1. Install a SharePoint technology instance. (Already did this when installing PowerPivot with SharePoint) 2. Install SQL Server 2008 R2 November CTP Reporting Services and specify that the report server use SharePoint Integrated mode 3. Configure Reporting Services 4. Download the Reporting Services Add-in by clicking the rsSharePoint.msi link later on this page. To start the installation immediately, click Run After installing Reporting services and the add-in your reporting server is ready to be integrated with SharePoint, in SharePoint 2010 we have some new admin screens. To integrate go to central admin, general application settings: When you successfully installed the add-in a reporting services icon will be there. Click Reporting Services Integration: Add the report server web service url (To get the URL, open the Reporting Services Configuration tool, connect to the report server, and click Web Service URL. Click the URL to verify it works. Copy the URL and paste it into Report Server Web Service URL.), select your authentication mode (windows authentication is prefered). Add a username and password of your admin account. Click ok to configure and start the integration. After the installation you can set the reporting services default. What is changed in SP2010 is that there isn’t a report library available. You have to add content types to a default library. So go to a site collection, site actions, View all site content. Create a Asset library: Now we have to make sure we can add reports to the library. To do this we have to add content types: Open the library, click on library tools, library settings, Under Content Types, click Add from existing site content types. In the Select Content Types section, in Select site content types from, click the arrow to select Reporting Services. In the Available Site Content Types list, click Report Builder, Report Data Source and Report and then click Add to move the selected content type to the Content types to add list.

  • Are there website monitoring services that can monitor HTTP file download times?

    - by Mark
    The software company I work for would like to monitor how long it takes to download their installers (hosted in several locations and about 30-100mb each) from various countries around the world. I am aware of website monitoring services like Pingdom and Site24x7, and have contacted their customer services, but neither have the facility to monitor download times of such large files via HTTP. For various reasons, we are not able to rely on weblogs. Does anyone know of any third-party services that could help us? Many thanks.

  • Message Buffers in cloud

    - by kaleidoscope
    Message Buffer is WCF queue in the cloud (although currently it does not provide all features of WCF queue). With on-premise WCF, you can take advantage of MSMQ, so that a message is sent to MSMQ by one endpoint, and another endpoint can get the message in a later time. The message is usually a SOAP message so that you can generate a client proxy and invoke the service operations just as invoking a normal WCF operation. Message Buffer is similar, but it also provides a REST API for you to work with the messages. Use it when you need a reliable WCF service. Message buffers can be consumed by non-azure components, "Message  buffers are accessible to applications using HTTP and do not require the Windows Azure platform AppFabric SDK"              How to: Configure an AppFabric Service Bus Message Buffer :    please find below link for more details: http://msdn.microsoft.com/en-us/library/ee794877.aspx http://msdn.microsoft.com/en-us/library/ee794877.aspx   Chandraprakash, S

  • WebLogic Server Weekly for March 26th, 2012: WLS 1211 Update, Java 7 Certification, Galleria, WebLogic for DBAs, REST and Enterprise Architecture, Singleton Services

    - by Steve Button
    WebLogic Server 12c Certified with Java 7 for Production Use WebLogic Server 12c (12.1.1) has been certified with JDK 7 for development usage since December and we have now completed JDK 7 certification for use with production systems. In doing so, we have updated the WebLogic Server 12c (12.1.1) distributions incorporating fixes associated with JDK 7 support as well as some bundled patches that address several issues that have been discovered since the initial release. These updated distributions are available for download from OTN and will be beneficial for all WebLogic Server 12c (12.1.1) users in general. What's New Release Notes Download Here! Updated Oracle WebLogic Server 12.1.1.0 distribution Never one to miss a trick, Markus Eisele was one of the first to notice the WebLogic Server 12c update and post a blog about it. Sources told me that as of Friday last week you have an updated version of WebLogic Server 12c on OTN. http://blog.eisele.net/2012/03/updated-oracle-weblogic-server-12110.html Using WebLogic Server 12c with Java 7 - Video To illustrate the use of Java 7 with WebLogic Server 12c, I put together a screen cam showing the creation of a domain using Java 7 and then build and deploy a simple web application that uses Java 7 syntax to show it working. Ireland OUG Presentation: WebLogic for DBAs Simon Haslam posted his slides from a presentation he gave Dublin on 21/3/12 at the OUG Ireland conference. In this presentation, he explains the core concepts and ideas behind WebLogic Server, walks through an installation and offers some tips and common gotcha's to avoid. Simon also covers some aspects of installing and use Enterprise Manager 12c. Note: I usually install the JVM and use the generic .jar installer rather than using an installer bundled with a JVM. http://www.slideshare.net/Veriton/weblogic-for-dbas-10h Slightly Retro: Jeff West on Enterprise Architecure and REST In this weeks flashback, we look at Jeff West's blog from early 2011 where he provides some thoughtful opinions on enterprise architecture and innovation, then jumps into his views on REST. After I progressed in my career and did more team-leading and architecture type roles I was ‘educated’ on what it meant to have Asynchronous and Long-Running processes as part of your Enterprise Application architecture. If I had a synchronous process then I needed a thread available to service the request and then provide the response. https://blogs.oracle.com/jeffwest/entry/weblogic_integration_wli_web_services_and_soap_and_rest_part_1 Starting Managed Servers without an Administration Server using Node Manager and WLST Blogger weblogic-tips shows how to start a managed server without going through the Administration Server, using the Node Manager and WLST. Connect WLST to a Node Manager by entering the nmConnect command. http://www.weblogic-tips.com/2012/02/18/starting-managed-servers-without-an-administration-server-using-node-manager-and-wlst/ Using WebLogic Server Singleton Services WebLogic Server has supported the notion of a Singleton Service for a number of releases, in which WebLogic Server will maintain a single instance of a configured singleton service on one managed server within a cluster. This blog demonstrates how the singleton service can be accessed and used from applications deployed on the cluster. http://buttso.blogspot.com.au/2012/03/weblogic-server-singleton-services.html

  • SOA Implementation Challenges

    Why do companies think that if they put up a web service that they are doing Service-Oriented Architecture (SOA)? Unfortunately, the IT and business world love to run on the latest hype or buzz words of which very few even understand the meaning. One of the largest issues companies have today as they consider going down the path of SOA, is the lack of knowledge regarding the architectural style and the over usage of the term SOA. So how do we solve this issue?I am sure most of you are thinking by now that you know what SOA is because you developed a few web services.  Isn’t that SOA, right? No, that is not SOA, but instead Just Another Web Service (JAWS). For us to better understand what SOA is let’s look at a few definitions.Douglas K. Bary defines service-oriented architecture as a collection of services. These services are enabled to communicate with each other in order to pass data or coordinating some activity with other services.If you look at this definition closely you will notice that Bary states that services communicate with each other. Let us compare this statement with my first statement regarding companies that claim to be doing SOA when they have just a collection of web services. In order for these web services to for an SOA application they need to be interdependent on one another forming some sort of architectural hierarchy. Just because a company has a few web services does not mean that they are all interconnected.SearchSOA from TechTarget.com states that SOA defines how two computing entities work collectively to enable one entity to perform a unit of work on behalf of another. Once again, just because a company has a few web services does not guarantee that they are even working together let alone if they are performing work for each other.SearchSOA also points out service interactions should be self-contained and loosely-coupled so that all interactions operate independent of each other.Of all the definitions regarding SOA Thomas Erl’s seems to shed the most light on this concept. He states that “SOA establishes an architectural model that aims to enhance the efficiency, agility, and productivity of an enterprise by positioning services as the primary means through which solution logic is represented in support of the realization of the strategic goals associated with service-oriented computing.” (Erl, 2011) Once again this definition proves that a collection of web services does not mean that a company is doing SOA. However, it does mean that a company has a collection of web services, and that is it.In order for a company to start to go down the path of SOA, they must take  a hard look at their existing business process while abstracting away any technology so that they can define what is they really want to accomplish. Once a company has done this, they can begin to factor out common sub business process like credit card process, user authentication or system notifications in to small components that can be built independent of each other and then reassembled to form new and dynamic services that are loosely coupled and agile in that they can change as a business grows.Another key pitfall of companies doing SOA is the fact that they let vendors drive their architecture. Why do companies do this? Vendors’ do not hold your company’s success as their top priority; in fact they hold their own success as their top priority by selling you as much stuff as you are willing to buy. In my experience companies tend to strive for the maximum amount of benefits with a minimal amount of cost. Does anyone else see any conflicts between this and the driving force behind vendors.Mike Kavis recommends in an article written in CIO.com that companies need to figure out what they need before they talk to a vendor or at least have some idea of what they need. It is important to thoroughly evaluate each vendor and watch them perform a live demo of their system so that you as the company fully understand what kind of product or service the vendor is actually offering. In addition, do research on each vendor that you are considering, check out blog posts, online reviews, and any information you can find on the vendor through various search engines.Finally he recommends companies to verify any recommendations supplied by a vendor. From personal experience this is very important. I can remember when the company I worked for purchased a $200,000 add-on to their phone system that never actually worked as it was intended. In fact, just after my departure from the company started the process of attempting to get their money back from the vendor. This potentially could have been avoided if the company had done the research before selecting this vendor to ensure that their product and vendor would live up to their claims. I know that some SOA vendor offer free training regarding SOA because they know that there are a lot of misconceptions about the topic. Superficially this is a great thing for companies to take part in especially if the company is starting to implement SOA architecture and are still unsure about some topics or are looking for some guidance regarding the topic. However beware that some companies will focus on their product line only regarding the training. As an example, InfoWorld.com claims that companies providing deep seminars disguised as training, focusing more about ESBs and SOA governance technology, and less on how to approach and solve the architectural issues of the attendees.In short, it is important to remember that we as software professionals are responsible for guiding a business’s technology sections should be well informed and fully understand any new concepts that may be considered for implementation. As I have demonstrated already a company that has a few web services does not mean that they are doing SOA.  Additionally, we must not let the new buzz word of the day drive our technology, but instead our technology decisions should be driven from research and proven experience. Finally, it is important to rely on vendors when necessary, however, always take what they say with a grain of salt while cross checking any claims that they may make because we have to live with the aftermath of a system after the vendors are gone.   References: Barry, D.
