He was part of an enterprise-level, open source portal application implementation for media and publication houses, portal customization projects, and led a team of developers to achieve the client's requirements on time.

Azaz Desai. He is responsible for implementing, deploying, integrating, and optimizing services and business processes using ESB and BPM tools. He is very enthusiastic and active in understanding client-specific requirements on web service integration.

The generated code provides the interface between the connector and Mule that would otherwise require each connector developer to include extensive boilerplate code, as well as the code and files required to interact with your connector in Anypoint Studio.

Download and install Java 1. Download and install Maven. Check Maven configuration in Anypoint Studio. Install Anypoint DevKit plugin. Clone tutorial repository into your local machine. For example, to clone to a dev folder, run:. The Cookbook is a service that helps users organize ingredients and recipes, so that users can easily find recipes for the foods they like to prepare.

The API also allows you to view recently added recipes. Custom with a username and password that provides a token to send with each request as part of the request. The rest base url is http: You can also run it locally since we provide the source code for the servers already ready to start.

MuleStoreServer class. By default it starts the server on address http: The local Rest Server can be run from the rest-server project by simple executing the com. Main class. This generates a project containing the structure and all required elements including a skeleton connector, images, sample docs file, but no basic tests for your connector. You can customize the icons by replacing the generated ones.

Just make sure that they have the same size so that they look good in Studio. You can check a detailed explanation of the relation between connector structure and Studio.

To solve this, DevKit provides a pair of annotations that let you modularize in different classes:. There are several types of configuration you can use as we will see in this tutorial. When you mark a field with Config, DevKit ensures that you have an initialized object set when the Mule app runs and that requests are made to your connector. Add our client dependency so that we can use it in our connector. On the Configuration ConnectorConfig add a configurable field for the address where the Cookbook service is hosted:.

Add a configurable field in our Configuration component with a default value for the endpoint our client connects to so that users can connect to different sandboxes. When a method is annotated with one of these annotations, DevKit invokes it during the lifecycle phase that the annotation represents.

Change it to reflect the getRecentlyAdded method signature, and there we have our first connector, ready to be tested.

Run the Generate Sources Action. At this point you can install this Connector and try it in Studio if you want. Once you regenerate the sources, the errors will go away as the generated code will be refreshed. When you add an example, use the same name as the name that narrows the example in the file.

Inside of it you have to put an example of the Processor. If you have the Javadoc check enabled, DevKit plugin marks the missing example as an error and provide a quick fix for us to easily add the example. You will do a very simple app that listens to an HTTP endpoint and when we hit it, it will retrieve the list of recently added elements.

Create a mule app and add a simple http listener. If this is your first mule app, take a look at our Hello World Application. If you hit the url http: Tests Automation documentation. The full testing documentation. The client you are using provides a login call that initializes the token and uses it in subsequent requests.

Take into account that the session can expire and cause the connector to make a login request again. DevKit provides a different set of annotations to keep your code clean and handle the connection in a different class for delegating responsibilities. To implement ConnectionManagement, you need to move the initialization to ConnectionManagement, instead of using the Start annotation as we did before.

ConnectionIdentifier - Return a string value. This will only be used when debugging. If you install this version and try to run the mule app we created before, you will see that it fails with a SAXParseException because we need to add a username and password to our configuration. Just open the global configuration of your connector and check that there are 2 new fields, username and password. Configure them and you can run the app again.

Check the Test Connectivity section. DevKit Authentication documentation. The Handler feature, is very useful when you want to avoid duplicated code when handling exceptions, and also so that your connector code is cleaner. When handling messages retrieved from the API, if the message is poor and you know how to improve it, you can use this mechanism, to enrich the error provided to the user. There is no need for users to add custom code in their Mule apps to handle session expiration.

DevKit provides a mechanism to do this in a clean way. In our Mule app, you can configure a reconnection strategy so that our Mule app is ready to handle session expirations.

DataSense improves the user experience at design time when creating Mule applications by enabling your connector to determine the API of your target resource. Even though DataSense is optional, its use enables connector users to acquire metadata of the entities in a service.

Adding DataSense. In this tutorial, we use a static DataSense model, which means that the entities are fixed and known upfront, and do not change. The fields that this model supports are also fixed. Analyze the entities in Mule Cookbook service. Look at how our createIngredient operation looks inside Anypoint Studio, and how it interacts with other components.

We defined the operation so that it receives an Ingredient, and it returns an Ingredient with the extra fields populated from the server. Check the input metadata to see that the expected output is a POJO, with the expected fields our Ingredient has:. Drag and drop a Transform Message element either behind or after our connector.

The Transform Message element automatically picks the input or output:. Because DevKit auto-generates static metadata, DevKit automatically ensures that your connector knows how to propagate metadata information.

The RefOnly annotation is used to tell DevKit that the input can only be specified as a reference due to a DevKit limitations on handling Abstract classes. The full source code of our connector with a create, update, get and delete operation is available here. To implement DataSense using a MetaDataCategory, you need to separate your implementation in two steps, retrieving the keys and describing the keys.

Modify the method annotate with MetaDataRetriever, to retrieve the description. Because we use a static model, we can just create a POJO model:. Annotate our Connector class with the MetaDataScope annotation. In your get operation you need specify that the affect only applies to the output so we modify it just a little:.

Check our new connector looks in Studio. We have a combo after we select the entity type and save it. This automatically refreshes our metadata. In the previous section we covered the scenario when your model is static. There are APIs that provide a way to get entity definitions dynamically.

Salesforce, NetSuite are just some examples of these. In our Connector now we need to add the code to generate the entities from the Map, and return Map in all our operations. Why is this important? To maintain consistency in our API. In our Mule app, we cannot update the metadata and use our connector. And, as you can see, note that we have a map structure instead of a POJO:. In order to show this feature you are going to add a processor that will call the searchWithQuery operation of the SDK.
