  • C# WCF client configuration for X509 secured web service over https

    - by Kam
    Hi guys I been pulling my hair out for the past few days trying to connect to a web service using .Net 3.5 and WCF (have also tried using WSE 3.0) without much luck. The web service is hosted by a 3rd party and we can access via https. They also make use of X509 certificates for security, to sign the message. I've been given some basic info and am able to connect and test the service using SOAP UI 3.5 without any problems, so we know that this is not the issue. Just trying to get it done in code! I've added the X509 certificate into the certificate store using the mmc snap-in, and using tracing and logging i can see that the message is being signed, just unable to see which part i have got wrong. Any healp GREATLY appreciated :) I've been given an offline WSDL file, which I have imported in as a service reference is VS 2008. My calling code looks like so, simple enough: ServicePointManager.ServerCertificateValidationCallback = delegate(object sender,X509Certificate certificate,X509Chain chain, SslPolicyErrors sslErrors) { return true; }; GatewayClient gateway = new GatewayClient(); CheckStatusResponse response = gateway.CheckLineStatus(); And my config looks like so: <basicHttpBinding> <binding name="Gateway_1.0" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="TransportWithMessageCredential"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="Certificate" algorithmSuite="Default" /> </security> </binding> </basicHttpBinding> <customBinding> <binding name="Gateway_1"> <security authenticationMode="CertificateOverTransport" includeTimestamp="true" messageProtectionOrder="SignBeforeEncrypt"> <localClientSettings maxClockSkew="12:00:00" replayWindow="12:00:00" sessionKeyRolloverInterval="12:00:00" timestampValidityDuration="12:00:00" /> <localServiceSettings maxClockSkew="12:00:00" sessionKeyRolloverInterval="12:00:00" timestampValidityDuration="12:00:00" /> <secureConversationBootstrap /> </security> <textMessageEncoding messageVersion="Soap11" /> <sslStreamSecurity requireClientCertificate="true" /> <httpsTransport hostNameComparisonMode="WeakWildcard" /> </binding> </customBinding> <wsHttpBinding> <binding name="Gateway_1" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <security mode="TransportWithMessageCredential"> <message clientCredentialType="Certificate" negotiateServiceCredential="false" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="https://XXX.XX.XXX.XX/SOAP" behaviorConfiguration="ClientCertificateBehavior" binding="wsHttpBinding" bindingConfiguration="Gateway_1" contract="B2BService.Gateway" name="Gateway_1_HTTPSPort"> <identity> <dns value="ext.test.com" /> </identity> </endpoint> </client> <behaviors> <endpointBehaviors> <behavior name="ClientCertificateBehavior"> <clientCredentials> <clientCertificate findValue="mycertificate.com" storeLocation="CurrentUser" storeName="Root" x509FindType="FindBySubjectName" /> <serviceCertificate> <authentication certificateValidationMode="PeerOrChainTrust" /> </serviceCertificate> </clientCredentials> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> Regardless of which config I use, the code fails for one reason or another, causing internal server errors, Error processing message for security, Undefined 'badEncoding' resource property, or expected http URI given https, and a few other! Been going round and round a bit, and I am sure it is very simple once the cofig is set :( I'm sure I've missed loads out, let me know if seeing the SOAP UI generated envelope and the currect WCF generated envelope will help. many thanks.

  • AS11 Oracle B2B Sync Support - Series 2

    - by sinkarbabu.kirubanithi
    In the earlier series, we discussed about how to model "Sync Support" in Oracle B2B. And, we haven't discussed how the response can be consumed synchronously by the back-end application or initiator of sync request. In this sequel, we will see how we can extend it to the SOA composite applications to model the end-to-end usecase, this would help the initiator of sync request to receive the response synchronously. Series 2 - is little lengthier for blog standards so be prepared before you continue further :). Let's start our discussion with a high-level scenario where one need to initiate a synchronous request and get response synchronously. There are various approaches available, we will see one simplest approach here. Components Involved: 1. Oracle B2B 2. Oracle JCA JMS Adapter 3. Oracle BPEL 4. All of the above are wrapped up in a single SOA composite application. Oracle B2B: Skipping the "Sync Support" setup part in B2B, as we have already discussed that in the earlier series 1. Here we have provided "Sync Support" samples that can be imported to B2B directly and users can start testing the same in few minutes. Initiator Sample: This requires two JMS queues to be created, one for B2B to receive initial outbound sync request and the other is for B2B to deliver the incoming sync response to the back-end. Please enable "Use JMS Id" option in both internal listening and delivery channels. This would enable JCA JMS Adapter to correlate the initial B2B request and response and in turn it would be returned as synchronous response of BPEL. Internal Listening Channel Image: Internal Delivery Channel Image: To get going without much challenges, just create queues in Weblogic with the JNDI mentioned in the above two screenshots. If you want to use different names, then you may have to change the queue jndi names in sample after importing it into B2B. Here are the Queue related JNDI names used in the sample, 1. Internal Listening Channel Queue details, Name: JNDI Name: jms/b2b/syncreplyqueue 2. Internal Delivery Channel Queue details, Name: JNDI Name: jms/b2b/syncrequestqueue Here is the Initiator Sample Acme.zip Note: You may have to adjust the ip address of GlobalChips endpoint in the Delivery Channel. Responder Sample: Contains B2B meta-data and the Callout. Just import the sample and place the callout binary under "/tmp/callout" directory. If you choose to use a different location for callout, then you may have to change the same in B2B Configuration after importing the sample. Here are the artifacts, 1. Callout Source SampleCallout.java 2. Callout Binary sample-callout.jar 3. Responder Sample GlobalChips.zip Callout Details: Just gives the static response XML that needs to be sent back as response for the inbound sync request. For a sample purpose, we have given static response but in production you may have to invoke a web service or something similar to get the response. IMPORTANT NOTE: For Sync Support use case, responder is not expected to deliver the inbound sync request to backend as the process of delivering and getting the response from backend are expected from the Callout. This default behavior can be overridden by enabling the config property "b2b.SyncAppDelivery=true" in B2B config mbean (b2b-config.xml). This makes B2B to deliver the inbound sync request to be delivered to backend queue but the response to be sent to remote caller still has to come from Callout. 2. Oracle JCA JMS Adapter: On the initiator side, we have used JCA JMS Request/Reply pattern to send/receive the synchronous message from B2B. 3. Oracle BPEL: Exposes WS-SOAP Endpoint that takes payload as input and passes the same to B2B and returns the synchronous response of B2B as SOAP response. For outside world, it looks as if it is the synchronous web service endpoint but under the cover it uses JMS to trigger/initiate B2B to send and receive the synchronous response. 4. Composite application: All the components discussed above are wired in SOA composite application that helps to model a end-to-end synchronous use case. Here's the composite application sca_B2BSyncSample_rev1.0.jar, you may just deploy this to your AS11 SOA to make use of it. For any editing, you can just import the project in your JDEV under any SOA Application. Here are the composite application screenshots, Composite Application: BPEL With JCA JMS Adapter (Request/Reply):

  • Eloqua API Full Code Example in JAVA

    - by Shawn Spencer
    Is there anyone out there who has mastered to retrieve some data programmatically from Eloqua? First of all, I'm more or less a newbie, as far as JAVA. I can follow tutorials, take directions and will Google till my fingers bleed. I understand the basics and am slightly familiar with OOP. My main problem is that I have a Friday deadline (and tomorrow is Thanksgiving). At any rate, all the Eloqua code snippets (that I've been able to find) illustrate one aspect of a specific issue, and that's it. In my case, I would greatly appreciate a JAVA project of some sort, with all the necessary files to do web services (WSDL, SOAP and perhaps WSIT) and the main class and all that included. No, I don't want you to do my work for me! Just give me enough to find my way around, enter the information I need to retrieve and all that. I'll take it from there. Any pointers, links or suggestions?

  • Demystified - BI in SharePoint 2010

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Frequently, my clients ask me if there is a good guide on deciphering the seemingly daunting choice of products from Microsoft when it comes to business intelligence offerings in a SharePoint 2010 world. These are all described in detail in my book, but here is a one (well maybe two) page executive overview. Microsoft Excel: Yes, Microsoft Excel! Your favorite and most commonly used in the world database. No it isn’t a database in technical pure definitions, but this is the most commonly used ‘database’ in the world. You will find many business users craft up very compelling excel sheets with tonnes of logic inside them. Good for: Quick Ad-Hoc reports. Excel 64 bit allows the possibility of very large datasheets (Also see 32 bit vs 64 bit Office, and PowerPivot Add-In below). Audience: End business user can build such solutions. Related technologies: PowerPivot, Excel Services Microsoft Excel with PowerPivot Add-In: The powerpivot add-in is an extension to Excel that adds support for large-scale data. Think of this as Excel with the ability to deal with very large amounts of data. It has an in-memory data store as an option for Analysis services. Good for: Ad-hoc reporting and logic with very large amounts of data. Audience: End business user can build such solutions. Related technologies: Excel, and Excel Services Excel Services: Excel Services is a Microsoft SharePoint Server 2010 shared service that brings the power of Excel to SharePoint Server by providing server-side calculation and browser-based rendering of Excel workbooks. Thus, excel sheets can be created by end users, and published to SharePoint server – which are then rendered right through the browser in read-only or parameterized-read-only modes. They can also be accessed by other software via SOAP or REST based APIs. Good for: Sharing excel sheets with a larger number of people, while maintaining control/version control etc. Sharing logic embedded in excel sheets with other software across the organization via REST/SOAP interfaces Audience: End business users can build such solutions once your tech staff has setup excel services on a SharePoint server instance. Programmers can write software consuming functionality/complex formulae contained in your sheets. Related technologies: PerformancePoint Services, Excel, and PowerPivot. Visio Services: Visio Services is a shared service on the Microsoft SharePoint Server 2010 platform that allows users to share and view Visio diagrams that may or may not have data connected to them. Connected data can update these diagrams allowing a visual/graphical view into the data. The diagrams are viewable through the browser. They are rendered in silverlight, but will automatically down-convert to .png formats. Good for: Showing data as diagrams, live updating. Comes with a developer story. Audience: End business users can build such solutions once your tech staff has setup visio services on a SharePoint server instance. Developers can enhance the visualizations Related Technologies: Visio Services can be used to render workflow visualizations in SP2010 Reporting Services: SQL Server reporting services can integrate with SharePoint, allowing you to store reports and data sources in SharePoint document libraries, and render these reports and associated functionality such as subscriptions through a SharePoint site. In SharePoint 2010, you can also write reports against SharePoint lists (access services uses this technique). Good for: Showing complex reports running in a industry standard data store, such as SQL server. Audience: This is definitely developer land. Don’t expect end users to craft up reports, unless a report model has previously been published. Related Technologies: PerformancePoint Services PerformancePoint Services: PerformancePoint Services in SharePoint 2010 is now fully integrated with SharePoint, and comes with features that can either be used in the BI center site definition, or on their own as activated features in existing site collections. PerformancePoint services allows you to build reports and dashboards that target a variety of back-end datasources including: SQL Server reporting services, SQL Server analysis services, SharePoint lists, excel services, simple tables, etc. Using these you have the ability to create dashboards, scorecards/kpis, and simple reports. You can also create reports targeting hierarchical multidimensional data sources. The visual decomposition tree is a new report type that lets you quickly breakdown multi-dimensional data. Good for: Mostly everything :), except your wallet – it’s not free! But this is the most comprehensive offering. If you have SharePoint server, forget everything and go with performance point. Audience: Developers need to setup the back-end sources, manageability story. DBAs need to setup datawarehouses with cubes. Moderately sophisticated business users, or developers can craft up reports using dashboard designer which is a click-once App that deploys with PerformancePoint Related Technologies: Excel services, reporting services, etc.   Other relevant technologies to know about: Business Connectivity Services: Allows for consumption of external data in SharePoint as columns or external lists. This can be paired with one or more of the above BI offerings allowing insight into such data. Access Services: Allows the representation/publishing of an access database as a SharePoint 2010 site, leveraging many SharePoint features. Reporting services is used by Access services. Secure Store Service: The SP2010 Secure store service is a replacement for the SP2007 single sign on feature. This acts as a credential policeman providing credentials to various applications running with SharePoint. BCS, PerformancePoint Services, Excel Services, and many other apps use the SSS (Secure Store Service) for credential control. Comment on the article ....

  • How can architects work with self-organizing Scrum teams?

    - by Martin Wickman
    An organization with a number of agile Scrum teams also has a small group of people appointed as "enterprise architects". The EA group acts as control and gatekeeper for quality and adherence to decisions. This leads to overlaps between the team decision and EA decisions. For instance, the team might want to use library X or want to use REST instead of SOAP, but the EA does not approve of that. Now, this can lead to frustration when team decisions are overruled. Taken far enough, it can potentially lead to a situation where the EA people "grabs" all power and the team ends up feeling demotivated and not very agile at all. The Scrum guides has this to say about it: Self-organizing: No one (not even the Scrum Master) tells the Development Team how to turn Product Backlog into Increments of potentially releasable functionality. Is that reasonable? Should the EA team be disbanded? Should the teams refuse or simply comply?

  • Web services, J2EE, Spring, DB integration project ideas - maybe data mining related?

    - by saral jain
    I am a graduate Computer Science student (Data Mining and Machine Learning) and have good exposure to core Java (3 years). I have read up on a bunch of stuff on the following topics: Design patterns, J2EE Web services (SOAP and REST), Spring, and Hibernate Java Concurrency - advanced features like Task and Executors. I would now like to do a project combining this stuff -- over my free time of course -- to get a better understanding of these things and to kind of make an end to end software (to learn the best design principles etc + SVN, maven). Any good project ideas would be really appreciated. I just want to build this stuff to learn, so I don't really mind re-inventing the wheel. Also, anything related to data mining would be an added bonus as it fits with my research but is absolutely not necessary since this project is more to learn to do large scale software development.

  • Common usecases and techniques when integrating a 3rd party application with Oracle Sales Cloud

    - by asantaga
    Over the last year or so I've see a lot of partners migrating and integrate their applications with Oracle Sales Cloud. Interestingly I'd say 60% of the partners use the same set of design patterns over and over again. Most of the time I see that they want to embed their application into Oracle Sales Cloud, within a tab usually, perhaps click on a link to their application (passing some piece of data + credentials) and then within their application update sales cloud again using webservices. Here are some examples of the different use-cases I've seen , and how partners are embedding their applications into Sales Cloud, NB : The following examples use the "Desktop" User Interface rather than the Newer "Simplified User Interface", I'll update the sample application soon but the integration patterns are precisely the same Use Case 1 :  Navigator "Link out" to third party application This is an example of where the developer has added a link to the global navigator and this links out to the 3rd Party Application. Typically one doesn't pass any contextual data with the exception of perhaps user credentials, or better still JWT Token. Techniques Used   Adding Link to Menu Item Using JWT Token in Sales Cloud Use Case 2 : Application Embedded within the Sales Cloud Dashboard Within the Oracle Sales Cloud application there is a tab called "Sales", within this tab its possible to embed a SubTab and embed a iFrame pointing to your application. To do this the developer simply needs to edit the page in customization mode, add the tab and then add the iFrame, simples! The developer can pass credentials/JWT Token and some other pieces of data but not object data (ie the current OpportunityID etc)  Techniques Used Adding a page to the dashboard  Using JWT Token in Sales Cloud  Use Case 3 : Embedding a Tab and Context Linking out from a Sales Cloud object to the 3rd party application In this usecase the developer embeds two components into Oracle Sales Cloud. The first is a SubTab showing summary data to the user (a quote in our case) and then secondly a hyperlink, (although it could be a button) which when clicked navigates the user to the 3rd party application. In this case the developer almost always passes context specific data (i.e. the opportunityId) and a security token (username password combo or JWT Token). The third party application usually takes the data, perhaps queries more data using the Sales Cloud SOAP/WebService interface and then displays the resulting mashup to the user for further processing. When the user has finished their work in the 3rd party application they normally navigate back to Oracle Sales Cloud using what's called a "DeepLink", ie taking them back to the object [opportunity in our case] they came from. This image visually shows a "Happy Path" a user may follow, and combines linking out to an application , webservice calls and deep linking back to Sales Cloud. Techniques Used Extending a SalesCloud application with a custom button Using JWT Token in Sales Cloud Extending Oracle Sales Cloud [Opportnity] with a custom tab exposing External Content Retrieving Data from Oracle Sales cloud using WebServices Coding some groovy script to generate the URLs required (Doc 1571200.1 on MyOracle Support) DeepLinking to specific Oracle Sales Cloud Pages (Doc 1516151.1 on My Oracle Support) Use-Case 4 :  Server Side processing/synchronization This usecase focuses on the Server Side processing of data, in this case synchronizing data. Here the 3rd party application is running on a "timer", e.g. cron or similar, and when triggered it queries data from Oracle Sales Cloud, then it queries data from the 3rd party application, determines the deltas and then inserts the data where required. Specifically here we are calling Oracle Sales Cloud using SOAP/WebServices and the 3rd party application is being communicated to using the REST API, for Oracle Sales Cloud one would use standard JAX-WS WebService calls and for REST one would use the JAX-RS api and perhap the Jackson api for managing JSON objects.. This is a very common use case and one which specifically lends itself to using the Oracle Java Cloud Service as the ideal application server where to host the mediator between the two applications.  Techniques Used Using JWT Token in Sales Cloud Integrating with the Oracle Java Cloud Service Retrieving Data from Oracle Sales cloud using WebServices General Resources The above is just a small set of techniques and use-cases which are used today. There are plenty of other sources of documentation and resources available on the internet but to get you started here are a few of my favourite places  Sales Cloud General Documentation Sales Cloud Customize Tab is useful for general customization of Sales Cloud Sales Cloud Integration Tab focuses on the 3rd party integration techniques  Official Oracle Fusion Developer Relations Blog Official Oracle Fusion Developer Relations YouTube Channel Enjoy integrating!

  • What is the difference between WCF service and a simple Web service in developing using .NET Framework?

    - by Steve Johnson
    My questions are: What is the difference between WCF service and a simple Web service in .NET Framework? What a WCF Service can do which a .NET Web service cant? In other words, what are the limitation of .NET Web services which were overcome in WCF services? I understand that WCF are REST based and .NET web services are SOAP based. But I need to know more than that. How a developer will make a design decision whether to developer a Web service or a WCF service?

  • Imitating Exchange Server's "RBAC AuthZ" in my own application... (is there something similar?)

    - by makerofthings7
    Exchange 2010 has a delegation model where groups of winrm cmdlets are essentally grouped into roles, and the roles assigned to a user. (Image source) This is a great & flexible model considering how I can leverage all the benefits of PowerShell, while using the right low level technologies (WCF, SOAP etc), and requiring no additional software on the client side. (Image source) Question(s) Is there a way for me to leverage Exchange's delegation model in my .NET application? Has anyone attempted to imitate this model? If I must start from scratch, how would I go about imitating this approach?

  • 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

  • Sequence for authentication on a decoupled client?

    - by A T
    Using a sequence diagram and example code could you explain to me how authentication works when the client is completely separated from the server? I.e.: you haven't generated any of the client using a server-side template engine, rather you are communicating using REST (SOAP xor HTTP) xor RPC (XML xor JSON) with javascript on the client-side. Specifically I would like to know the sequence of: Authenticating using basic auth (user+pass) with "my" server Authenticating using OAuth2, e.g.: with Facebook, with facebook's server then whatever extra steps are needed for "my" server And how it could be implemented. (feel free to use psuedo-code [like below] or [preferably] prototyped simply using BackboneJS, AngularJS, EmberJS, BatmanJS, AgilityJS, SammyJS xor ActiveJS. if cookie.status in [Expired, Tampered, Wrong IP, Invalid, Not Found]: try auth(user,pass): if user is in my db: try authenticate(user,pass) if successful: login user # give session-cookie here? else: present user with "auth failed" msg else if user not in db: redirect to "edit-profile" page PS: I have written an example (editable) auth sequence diagram; based on facebooks' documentation.

  • Build Controller status Unavailable issue in TFS2010

    - by jehan
    I ran into this problem few days back, I was not able to run the builds because the Build Controller was showing Status as Unavailable. It was showing the below exception: There was no endpoint listening at http://fullmachinename:9191/Build/v3.0/Services/Controller/2 that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. After trying out few things, I looked at below Build Service Properties.   Then, I did below modifications to the Build Services Properties: 1)      Changed the Local Build Service Endpoint(incoming) from http://machinename.domain.com:9191 to http://machinename:9191 2)      Changed the Connect to Team Project Collection (outgoing) from localhost to machine name. http://localhost:8080/tfs/defaultCollection to http://machinename:8080/tfs/DefaultCollection   After that Started the Build Services and it fixed the issue, the Build Controller was showing Available Status and was able to run the builds.

  • Help me classify this type of software architecture

    - by Alex Burtsev
    I read some books about software architecture as we are using it in our project but I can't classify the architecture properly. It's some kind of Enterprise Architecture, but what exactly... SOA, ESB (Enterprise Service Bus), Message Bus, Event Driven SOA, there are so many terms in Enterprise software.... The system is based on custom XML messages exchanges between services. (it's not SOAP, nor any other XML based standard, just plain XML). These messages represent notifications (state changes) that are applied to the Domain model, (it's not like CRUD when you serialize the whole domain object, and pass it to service for persistence). The system is centralized, and system participants use different programming languages and frameworks (c++, c#, java). Also, messages are not processed at the moment they are received as they are stored first and the treatment begins on demand. It's called SOA+EDA -:)

  • Should I use both WCF and ASP.NET Web API

    - by Mithir
    We already have a WCF API with basichttpbinding. Some of the calls have complex objects in both the response and request. We need to add RESTful abilities to the API. at first I tried adding a webHttp endpoint, but I got At most one body parameter can be serialized without wrapper elements If I made it Wrapped it wasn't pure as I need it to be. I got to read this, and this (which states "ASP.NET Web API is the new way to build RESTful service on .NET"). So my question is, should I make 2 APIs(2 different projects)? one for SOAP with WCF and one RESTful with ASP.NET Web API? is there anything wrong architecturally speaking with this approach?

  • Recommended solutions for integrating iOS with .NET, at the service tier

    I'm developing an application, in iOS, that is required to connect to my Windows Server to poll for new data, update, etc. As a seasoned C# developer, my first instinct is to start a new project in Visual Studio and select Web Service, letting my bias (and comfort level) dictate the service layer of my application. However, I don't want to be biased, and I don't base my decision on a service which I am very familiar with, at the cost of performance. I would like to know what other developers have had success using, and if there is a default standard for iOS service layer development? Are there protocols that are easier to consume than others within iOS? Better ones for the size and/or compression of data? Is there anything wrong with using SOAP? I know it's "big" in comparison to protocols like JSON.

  • web services, J2EE, spring, DB integration project ideas- maybe data mining related?

    - by sj88
    Hey guys, I am a graduate CS student (Data mining and machine learning) and have a good exposure to core JAVA (3 years). I have read up a bunch of stuff on Design patterns J2EE Web services( soap and rest) spring and hibernate Java Concurrency - advanced features like Task and Executors. I would now like to do a project combining this stuff (over my free time of corse) to get a better understanding of these things and to kind of make an end to end software (to learn the best design principles etc + svn, maven). Any good project ideas would be really appreciated. I just wanna build this stuff to learn so I dont really mind re-inventing the wheel. Also, anything related to data mining would be an added bonus (fits with my research) but absolutly not necesary (since this project is more to learn to do large scale software developement)

  • Calling Web Service with Complex Parameters in ADF Mobile

    - by Shay Shmeltzer
    Many of the SOAP based web services out there have parameters of specific object types - so not just simple String/int inputs. The ADF Web service data control makes it quite simple to interact with them. And this applies also in the case of ADF Mobile. Since there were several thread on OTN asking about this - I thought I'll do a quick demo to refresh people memory about how you pass these "complex" parameters to your Web service methods. By the way - this video is also relevant if you are not doing mobile development, you'll basically use the exact same process for building "regular web" ADF applications that access these types of Web services. One more thing you might want to do after you create the page is look at the binding tab to see the method call in there, and notice the parameters for it in the structure property. Go and look at their NDValue property to get the complete picture.

  • What does RESTful web applications mean? [closed]

    - by John Cooper
    Possible Duplicate: What is REST (in simple English) What does RESTful web applications mean? A web service is a function that can be accessed by other programs over the web (Http). To clarify a bit, when you create a website in PHP that outputs HTML its target is the browser and by extension the human being reading the page in the browser. A web service is not targeted at humans but rather at other programs. SOAP and REST are two ways of creating WebServices. Correct me if i am wrong? What are other ways i can create a WebService? What does it mean fully RESTful web Application?

  • Best Practice to return responses from service

    - by A9S6
    I am writing a SOAP based ASP.NET Web Service having a number of methods to deal with Client objects. e.g: int AddClient(Client c) = returns Client ID when successful List GetClients() Client GetClientInfo(int clientId) In the above methods, the return value/object for each method corresponds to the "all good" scenario i.e. A client Id will be returned if AddClient was successful or a List< of Client objects will be returned by GetClients. But what if an error occurs, how do I convey the error message to the caller? I was thinking of having a Response class: Response { StatusCode, StatusMessage, Details } where Details will hold the actual response but in that case the caller will have to cast the response every time. What are your views on the above? Is there a better solution?

  • Best strategy to discover a web service in a local network?

    - by Ucodia
    I am currently doing some research for a project. The setup is simple, I have a computer running a service in my home network and any device connected to that same network should be able to discover the service automatically and use it. I have no specific technology requirement whether it is on the server or client side. The client knows about the service definition. Other than that I have no idea what strategy to use, what technology to look at or whether I should go for a SOAP or a HTTP based service. I think going HTTP with REST API is the best for targeting all devices but I am opened to any suggestions. Thanks.
