  • Consuming Web Services in Netbeans

    - by Seven
    Hi. I've setup a project in Netbeans 6.5 with some web services that I've created myself and some web services that I've imported from WSDL files. I've setup a couple of desktop application through Netbeans in order to consume these web services. I'm not too sure where to go from here. I have the GUI setup but not sure how to reference the web services so they can be consumed. I was wondering would anybody be able to guide me through this process or point me in the direction of a relevant tutorial. I'd also like to learn how to consume a web service through a JSP (also created in Netbeans) if possible. Thanks.

  • How do I call exec in psake to an executable with a variable path?

    - by Josh Kodroff
    I can't seem to call this executable correctly in my psake deploy script. If I do this: exec { "$ArchiverOutputDir\NServiceBus.Host.exe /install" } It simply outputs this (and is clearly not calling the executable - just outputting the value of that expression): c:\ReloDotNet2_ServiceEndpoints\Archiver\NServiceBus.Host.exe /install But if I do this: exec { c:\ReloDotNet2_ServiceEndpoints\Archiver\NServiceBus.Host.exe /install } I get the expected output from the executable. How do I correctly call an executable with a variable in the path to the executable in psake? If this is actually a PowerShell issue, please feel free to correct the question to reflect that insight. I

  • Best strategy for moving data between physical tiers in ASP.net

    - by Pete Lunenfeld
    Building a new ASP.net application, and planning to separate DB, 'service' tier and Web/UI tier into separate physical layers. What is the best/easiest strategy to move serialized objects between the service tier and the UI tier? I was considering serializing POCOs into JSON using simple ASP.net pages to serve the middle tier. Meaning that the UI/Web tier will request data from a (hidden to the outside user) web server that will return a JSON string. This kind of JSON 'emitter' seems easily testable. It also seems easily compressible for efficiently moving data over the WAN between tiers. I know that some folks use .asmx webservices for this kind of task, but this seems like there is excess overhead with SOAP, and the package is not as human readable (testable) as POCOs serialized as JSON. Others are using more complex technology like WCF which we have never used. Does anyone have advice for choosing a method for moving data/objects between the data (db) tier and the web (UI) tier over the WAN using .net technologies? Thanks!!!

  • Dealing with dependencies between WCF services when using Castle Windsor

    - by Georgia Brown
    I have several WCF services which use castle windsor to resolve their dependencies. Now I need some of these services to talk to each other. The typical structure is service -- Business Logic -- DAL The calls to the other services need to occur at Business Logic level. What is the best approach for implementing this? Should I simply inject a service proxy into the business logic? Is this wasteful if for example, only one of two method from my service need to use this proxy? What if the services need to talk to each other? - Will castle windsor get stuck in a loop trying to resolve each services dependencies?

  • Can I call make runtime decided method calls in Java?

    - by Catalin Marin
    I know there is an invoke function that does the stuff, I am overall interested in the "correctness" of using such a behavior. My issue is this: I have a Service Object witch contains methods which I consider services. What I want to do is alter the behavior of those services without later intrusion. For example: class MyService { public ServiceResponse ServeMeDonuts() { do stuff... return new ServiceResponse(); } after 2 months I find out that I need to offer the same service to a new client app and I also need to do certain extra stuff like setting a flag, or make or updating certain data, or encode the response differently. What I can do is pop it up and throw down some IFs. In my opinion this is not good as it means interaction with tested code and may result in un wanted behaviour for the previous service clients. So I come and add something to my registry telling the system that the "NewClient" has a different behavior. So I'll do something like this: public interface Behavior { public void preExecute(); public void postExecute(); } public class BehaviorOfMyService implements Behavior{ String method; String clientType; public void BehaviorOfMyService(String method,String clientType) { this.method = method; this.clientType = clientType; } public void preExecute() { Method preCall = this.getClass().getMethod("pre" + this.method + this.clientType); if(preCall != null) { return preCall.invoke(); } return false; } ...same for postExecute(); public void preServeMeDonutsNewClient() { do the stuff... } } when the system will do something like this if(registrySaysThereIs different behavior set for this ServiceObject) { Class toBeCalled = Class.forName("BehaviorOf" + usedServiceObjectName); Object instance = toBeCalled.getConstructor().newInstance(method,client); instance.preExecute(); ....call the service... instance.postExecute(); .... } I am not particularly interested in correctness of code as in correctness of thinking and approach. Actually I have to do this in PHP, witch I see as a kind of Pop music of programming which I have to "sing" for commercial reasons, even though I play POP I really want to sing by the book, so putting aside my more or less inspired analogy I really want to know your opinion on this matter for it's practical necessity and technical approach. Thanks

  • Spring can't find a lib and webapp doesn't start up in tomcat 6

    - by gotch4
    I've this problem using STS: I'm building a simple Spring app, just to try out features like MVC and persistence. Now I've created something very simple, out of a bunch of tutorials for Spring 3, that I'm using. The application fails with this, during server startup: Code: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean] for bean with name 'mySessionFactory' defined in ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]; nested exception is java.lang.ClassNotFoundException: org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean but I've org.springframework.orm in web-inf/classes folder (I even tried putting it in web-inf/lib). As I copied these libs there, the came out in Web App Libraries folder. Building this project in STS works fine as this dependency is set up in build path throught project properties, but how do I transfer the libs to the web app? (I'm using Tomcat 6 as it is the server I'm going to use sometime in the future for production). Is this a config problem of my XML? Or am I just missing the right way to put this lib? (I encountered the same problem before, but adding the needed lib in classes worked it out). More than this I that if I browse inside my workspace to the folder where the working folder of tomcat should be, I can't find any work directory and any commo

  • Does mcrypt support asymmetric encryption?

    - by bryanagee
    I want to use asymmetric encryption of headers in RESTful requests to verify the identity of the system sending the request: i e System A encrypts it's name, timestamp, and the service name using it's public key in a request to System B. System B then uses the public key of System A to decrypt, proving the authenticity of the request. 1) Does php-mcrypt support this? 2) Has anyone benchmarked this type of operation?

  • JSONP Implications with true REST

    - by REA_ANDREW
    From my understanding JSONP can only be achieved using the GET verb. Assuming this is true which I think it is, then this rules out core compliance with true REST in which you should make use of different verbs i.e. GET,PUT,POST,DELETE etc... for different and specific purposes. My question is what type of barriers am I likely to come up against if I where to say allow updating and deleting of resources using a JSONP service using a get request. Is it better practice to offer a JSON service and state that the user will need a server side proxy to consume using JavaScript XDomain? Cheers , Andrew

  • How should my team decide between 3-tier and 2-tier architectures?

    - by j0rd4n
    My team is discussing the future direction we take our projects. Half the team believes in a pure 3-tier architecture while the other half favors a 2-tier architecture. Project Assumptions: Enterprise business applications Business logic needed between user and database Data validation necessary Service-oriented (prefer RESTful services) Multi-year maintenance plan Support hundreds of users 3-tier Team Favors: Persistant layer <== Domain layer <== UI layer Service boundary between at least persistant layer and domain layer. Domain layer might have service boundary between it. Translations between each layer (clean DTO separation) Hand roll persistance unless we can find creative yet elegant automation 2-tier Team Favors: Entity Framework + WCF Data Service layer <== UI layer Business logic kept in WCF Data Service interceptors Minimal translation between layers - favor faster coding So that's the high-level argument. What considerations should we take into account? What experiences have you had with either approach?

  • How to design WCF Contracts?

    - by Amitabh
    We are designing a WCF layer which can be invoked either by a Asp.Net or a WinForm application. Our Application contains too many Entities. If we design WCF Contract around these entities then we get too many Contracts e.g IPartyService, IUserService, IPaymentService etc. So, I may end up with 30-40 Contracts? Is it a good idea or should we go for one huge contracts with around 100 operations? What are the pros and cons of each approach or is there a better way.

  • Creating an n tiered application

    - by aaron
    I am researching architecture for a project that will be started next year. It is mainly a c# web app, but there will be a service layer so that it can talk to our facebook/iphone app. There are a few long running processes, which means that I will be creating a windows process that can handle those. I’m thinking of putting the entire app in the windows service instead of just the long running processes. Asp - wcf - bll Vs Asp - bll I know this will be more scalable. But it is probably overkill as everything will be running on the same box, even the database. This could change down the road if the server can’t handle the traffic like marketing says it will. I don’t have access to production hardware, just my crappy testing box and my local machine. Has anyone decided to go down this route? But mostly, what is the best way to test both methods to get some metrics?

  • Is this the Crudy anti pattern?

    - by miker169
    Currently I am creating a WCF service which has to connect to a DAL which, just connects to a database using ADO.net and stored procedures. The DAl writes its responses from the database to a datacontract which is passed over the wire to the client via the service. I was reading that this may possibly be the anti pattern 'CRudy Interface', but I wasn't sure as I am sharing the datacontract. If I am using an anti pattern, can anyone suggest a better pattern to use for the behavior I require? Thanks

  • Is Domain Anaemia appropriate in a Service Oriented Architecture?

    - by Stimul8d
    I want to be clear on this. When I say domain anaemia, I mean intentional domain anaemia, not accidental. In a world where most of our business logic is hidden away behind a bunch of services, is a full domain model really necessary? This is the question I've had to ask myself recently since working on a project where the "domain" model is in reality a persistence model; none of the domain objects contain any methods and this is a very intentional decision. Initially, I shuddered when I saw a library full of what are essentially type-safe data containers but after some thought it struck me that this particular system doesn't do much but basic CRUD operations, so maybe in this case this is a good choice. My problem I guess is that my experience so far has been very much focussed on a rich domain model so it threw me a little. The remainder of the domain logic is hidden away in a group of helpers, facades and factories which live in a separate assembly. I'm keen to hear what people's thoughts are on this. Obviously, the considerations for reuse of these classes are much simpler but is really that great a benefit?

  • Architect desperately wants to use SOAP over JMS

    - by Aerosteak
    Hello, I have used JMS in the past to build application and it works great. Now I work with Architects that would love to use the Spec : SOAP over Java Message Service 1.0. This spec seams overly complicated. I do not see many implementation (Beside the vendors pushing for the spec). Does anyone here is using this specification in a production environment? What is your main benefit of using this spec? Link: http://www.w3.org/TR/2009/CR-soapjms-20090604/

  • rake test and test_structure.sql

    - by korinthe
    First of all, I have to run "rake RAILS_ENV=test ..." to get the test suites to hit my test DB. Annoying but ok to live with. However when I do so, I get a long stream of errors like so: > rake RAILS_ENV=test -I test test:units psql:/path/to/project/db/test_structure.sql:33: ERROR: function "armor" already exists with same argument types [and many more] It looks like some DB definitions are getting unnecessarily reloaded. I can't find any mention of this on Google, so I was wondering whether others have seen this? I am using a PostgreSQL database with the following in my environment.rb: config.active_record.schema_format = :sql and using Rails 2.3.5 with rake 0.8.7.

  • ADO.net Data Services - Querying

    - by Prajuvan
    Just I started learning ADO.NET Data Services. Some Pages show the querying like (sample) http://localhost:1705/ServiceExample/SomeService.svc/Persons(1)/Name http://localhost:1705/ServiceExample/SomeService.svc/Persons(1)/Name/$value Is it XPath or XQuery? Where can i get complete rules for forming such queries with examples? Thanks in advance.

  • web service data type (contract)

    - by cyberguest
    hi, i have a general design question. we have a fairly big data model that represents an clinical object, the object itself has 200+ child attributes in the hierarchy. and we have a SetObject operation, and a GetObject operation. my question is, best practice wise, would it make sense to use that single data model in both operations or different data model for each? Because the Get operation will return much more details than what's needed for Set. an example of what i mean: the data model has say ProviderId, and ProviderName attributes, in the Get operation, both the ProviderId, and ProviderName would need to be returned. However, in the Set operation, only the ProviderId is needed, and ProviderName is ignored by the service since system has that information already. In this case, if the Get and Set operations use the same data model, the ProviderName is exposed even for Set operation, does that confuse the consuming developer?

  • Can SpringSource Tool Suite build compliant EARs for WebSphere 6.1?

    - by bart
    I read on the website that SpringSource Tool Suite has build targets for WebSphere. Flexible Deployment Targets Support for all the most common Java EE application servers At the moment we are getting grief from infrastructure as we are giving them WARs built in ant. They are used to taking EAR files built straight out of RAD or RSA. Does SS Tool Suite have the capability to build compliant EARs for Websphere 6.1?

  • Is One Tool or a Suite of Tools Better for Scrum?

    - by Rob Wells
    G'day, Edit: We've been using Scrum very successfully for several years on several projects of varying sizes. In fact, our team developed the successful iPlayer project for the BBC using a classical Scrum approach. After using various combinations of tools, some high-tech, some low-tech, across these projects we now wish to try adopting a suitable tool suite. Our manager is to some extent attempting to force the adoption of a single suite of tools for Scrum. I've looked at the SO question "Best Scrum tools" and most people seem to recommend either: a suite of low-tech solutions, e.g. whiteboards, post-its, index cards, etc., or a monolithic tool that tries to satisfy as much as possible of the process, e.g. Agilo, Mingle, ScrumWorks, Target Process, etc. Our team is currently evaluating several different Scrum tools. However, we are looking at selecting a single, monolithic tool, e.g. Agilo. All of the "one-stop" solutions have their strengths and weaknesses with the serious enterprise type solutions being the best sort of fit. But all have some short comings. After reading the paper "Peer Code Review: An Agile Process" over at SmartBear I started wondering if we were trying to force adoption of a tool on a "best fit" basis. I think you can take a couple of reference artefacts of the Scrum development process, say user stories, epics and themes, and the code base which must use a well-known SCM, e.g. SVN, Hg, etc. Then if we take that as the common reference points for the tools employed then we would be able to use a group of tools to handle the different aspects of the Scrum process rather than try forcing a fit of a single tool would is a bit like forcing a square peg into the round hole. In this way, providing you've agreed your common reference points, you can use several tools, each performing their role better than a could be done by a single component in a monolithic tool suite. Is this a more sensible approach? Are the two reference points I mentioned above suitable, or is their a better choice of points where the tools would meet? cheers,

  • How do I install Photoshop CS2 in Wine w/ Creative Suite Installer?

    - by kellishaver
    I'm running Ubuntu 9.10 and wanted to install Photoshop CS2 in Wine (wine1.2). From what I've read, the Photoshop installer and application should both run fine. However, I don't have a specific installer for Photoshop. The setup program on the CD is for the entire Creative Suite 2 bundle. When I try to run it, I get through the splash screen, license agreement, and language selection screens, but when I click the button to start/customize the installation, the installer dies. The Photoshop CS 2 folder on the CD has two exe files, instmsia.exe and instmsiw.exe, and I tried those, hoping to find a stand-alone Photoshop installer, but neither work. I tried downloading a trial, but my license key is apparently for the entire bundle, because it didn't work. Does anyone know of a work-around for this or a way to make the Creative Suite installer work? I'm currently running Photoshop under a WinXP VM, but it would be nice to have the option of using it via Wine, so I don't have to boot the VM every time I want to edit an image (and also reading/writing to my Ubuntu shares is really slow in Virtualbox). Thanks!

  • Why can't I send SOAP requests to Ebay finding API with this php?

    - by Jay
    This is my code: <?php error_reporting(E_ALL); //new instance of soapClient pointing to Ebay finding api $client = new SoapClient("http://developer.ebay.com/webservices/finding/latest/FindingService.wsdl"); //attach required parameters to soap message header $header_arr = array(); $header_arr[] = new SoapHeader("X-EBAY-SOA-MESSAGE-PROTOCOL", "SOAP11"); $header_arr[] = new SoapHeader("X-EBAY-SOA-SERVICE-NAME", "FindingService"); $header_arr[] = new SoapHeader("X-EBAY-SOA-OPERATION-NAME", "findItemsByKeywords"); $header_arr[] = new SoapHeader("X-EBAY-SOA-SERVICE-VERSION", "1.0.0"); $header_arr[] = new SoapHeader("X-EBAY-SOA-GLOBAL-ID", "EBAY-GB"); $header_arr[] = new SoapHeader("X-EBAY-SOA-SECURITY-APPNAME", "REMOVED"); $header_arr[] = new SoapHeader("X-EBAY-SOA-REQUEST-DATA-FORMAT", "XML"); $header_arr[] = new SoapHeader("X-EBAY-SOA-MESSAGE-PROTOCOL", "XML"); $test = $client->__setSoapHeaders($header_arr); $client->__setLocation("http://svcs.ebay.com/services/search/FindingService/v1");//endpoint $FindItemsByKeywordsRequest = array( "keywords" => "potter" ); $result = $client->__soapCall("findItemsByKeywords", $FindItemsByKeywordsRequest); //print_r($client->__getFunctions()); //print_r($client->__getTypes()); //print_r($result); ? And this is the error I receive: Fatal error: Uncaught SoapFault exception: [axis2ns2:Server] Missing SOA operation name header in C:\xampplite\htdocs\OOP\newfile.php:25 Stack trace: #0 C:\xampplite\htdocs\OOP\newfile.php(25): SoapClient-__soapCall('findItemsByKeyw...', Array) #1 {main} thrown in C:\xampplite\htdocs\OOP\newfile.php on line 25 It doesnt make sense, I have already set the operation name in the header of the request...
