The following sections provide information about creating and using SOAP message handlers:Overview of SOAP Message HandlersAdding SOAP Message Handlers to a Web Service: Main StepsDesigning the SOAP Message Handlers and Handler ChainsCreating the GenericHandler ClassConfiguring Handlers in the JWS FileCreating the Handler Chain Configuration FileCompiling and Rebuilding the Web ServiceCreating and Using Client-Side SOAP Message HandlersOverview of SOAP Message HandlersSome Web Services need access to the SOAP message, for which you can create SOAP message handlers.A SOAP message handler provides a mechanism for intercepting the SOAP message in both the request and response of the Web Service. You can create handlers in both the Web Service itself and the client applications that invoke the Web Service.A simple example of using handlers is to access information in the header part of the SOAP message. You can use the SOAP header to store Web Service specific information and then use handlers to manipulate it.You can also use SOAP message handlers to improve the performance of your Web Service. After your Web Service has been deployed for a while, you might discover that many consumers invoke it with the same parameters. You could improve the performance of your Web Service by caching the results of popular invokes of the Web Service (assuming the results are static) and immediately returning these results when appropriate, without ever invoking the back-end components that implement the Web Service. You implement this performance improvement by using handlers to check the request SOAP message to see if it contains the popular parameters.The following table lists the standard JWS annotations that you can use in your JWS file to specify that a Web Service has a handler chain configured; later sections discuss how to use the annotations in more detail. For additional information, see the Web Services MetaData for the Java Platform (JSR-181) specification at 9-1 JWS Annotations Used To Configure SOAP Message Handler ChainsJWS AnnotationDescriptionjavax.jws.HandlerChainAssociates the Web Service with an externally defined handler chain. Use this annotation when multiple Web Services need to share the same handler configuration, or if the handler chain consists of handlers for multiple transports.javax.jws.soap.SOAPMessageHandlersSpecifies a list of SOAP handlers that run before and after the invocation of each Web Service operation. Use this annotation (rather than @HandlerChain) if embedding handler configuration information in the JWS file itself is preferred, rather than having an external configuration file.The @SOAPMessageHandler annotation is an array of @SOAPMessageHandlers. The handlers are executed in the order they are listed in this array.Note; This annotation works with JAX-RPC Web Services only.javax.jws.soap.SOAPMessageHandlerSpecifies a single SOAP message handler in the @SOAPMessageHandlers array.The following table describes the main classes and interfaces of the javax.xml.rpc.handler API, some of which you use when creating the handler

Explore samples on action and search based message extensions. medium overview anclear 01/23/2025 Build message extensionsMessage extensions enable users to engage with your web service through buttons and forms within the Microsoft Teams client. Users can search or initiate actions in an external system from the compose message area, the command box, or directly from a message. The results of these interactions can be returned to the Teams client as a richly formatted card.The article provides an overview of message extensions, use cases, functionality, action and search commands, and link unfurling.The following image displays the locations from where message extensions can be invoked:Note@mentioning message extensions in the compose box isn't supported.Message extension options aren't supported for group chats with external users.Desktop:::image type="content" source="../assets/images/messaging-extension-invoke-locations.png" alt-text="Screenshot shows the message extensions invoke location on Teams desktop.":::Mobile:::image type="content" source="../assets/images/messaging-extension-invoke-location-mobile.png" alt-text="Screenshot shows the message extensions invoke location on Teams mobile.":::Scenarios where message extensions are usedScenarioExampleYou need an external system to perform an action and return the result to your conversation.Reserve a resource and allow the channel to know the reserved time slot.You need to search for something in an external system and share the results with the conversation.Search for a work item in Azure DevOps and share it with the group as an Adaptive Card.You want to complete a complex task involving multiple steps or large amounts of information in an external system and share the results with a conversation.Create a bug in your tracking system based on a Teams message, assign that bug, and send a card to the conversation thread with the bug's details.Understand how message extensions workA message extension is composed of a web service hosted by you and an app manifest that defines the location where your web service is invoked within the Teams client. The web service utilizes the Bot Framework's messaging schema and secure communication protocol, so you must register your web service as a bot in the Bot Framework.NoteThough it's possible to manually create the web service, we recommend to use Bot Framework SDK to work with the protocol.In the app manifest (previously called as Teams app manifest), a single message extension is defined with up to 10 different commands. Each command defines a type, such as action or search and the locations in the client from where the message extension is invoked. The invoke locations include the compose message area, command bar, and message. On invoke, the web service receives an HTTPS message with a JSON payload with all the relevant information. Respond with a JSON payload to inform the Teams client of the next interaction to enable.Message extension commands typesThere are two types of message extension commands, action command and search command. The message extension command type defines the UI elements and interaction flows available to your web service. Certain interactions, such as authentication and configuration, are available for both commands types.Action commandsAction

WebView2Browser makes use of set of very useful WebView2 APIs for this purpose, including PostWebMessageAsJson, add_WebMessageReceived and ICoreWebView2WebMessageReceivedEventHandler.

Windows, Username, and Certificate. Use a Windows service to execute in the background and in its own process space, with a specific user identity. Usually, it does not involve any user interaction. Create a secure SOAP message in the Web service and use the SoapFilter class in the Web service to filter the SOAP message. Create a secure SOAP message in the Web service and use the ReceiveSecurityFilter class in the Web service to handle the receiving and securing of SOAP messages. Create a secure SOAP message in the Web service and use the SendSecurityFilter class in the Web service to handle the transmission and securing of SOAP messages. Develop a Windows application and use Microsoft SQL Server as a backend database to perform declarative and imperative security checks. Use a Web service to implement an application to send messages and create a new object of the SoapSender class, and implement the required namespaces. Create a new handler class that inherits from the SoapReceiver class and override the Receive method, and process the message parameter according to the requirement. Use a Web service to create a SOAP message to define a messaging connection that allows messages to be received from a given endpoint using HTTP with the help of the SoapHttpInputChannel class and perform asynchronous receive operation. Use a Web service to create a SOAP message to define a messaging connection that allows messages to be sent a given endpoint using HTTP with the help of the SoapHttpInputChannel class and perform.
