WSO2 ESB Training
WSO2 ESB Training Introduction:
WSO2 ESB Training (Enterprise Service Bus) is how applications talk to each other in systems without a WSO2 enterprise Service bus every application talks to other application causing a spaghetti mess. let’s think every application talking to one single application both for sending and retrieving messages, that single application is the enterprise service bus or the ESB. An ESB an can also combine data from multiple applications and act as a single system of record you can also add terabytes of memory as big memory and store the data in cache for quick retrieval. It can provide uninterrupted data to consuming systems even when one or more source systems are down for maintenance. WSO2 ESB Training explains it can expose the data as a set of common services that internal and external consumers can use to get the latest data instantaneously.
Prerequisties Of WSO2 ESB Training:
- Basic programming experience
- Basic understanding of Message Oriented Middleware
- Basic XML understanding
- Basic understanding of Web services and related standards (SOAP, WSDL)

Tooling in WSO2 ESB Training:
Wso2 ESB Training is explaining brief tooling component is a replacement for WSO2 develops at the studio. It provides capabilities of an Eclipse-based development environment for WSO2 ESB Training. You can develop debug and deploy your service features and artifacts and also manage the dependencies through a simplified graphical editor. We are WSO2- ESP tooling is patrolling ensures reusability maintainability and extensibility of ESB artifacts. The ESB tooling has been empowered with visual data mapping and mediation debugger features that are disused in two separate screencasts. Then you have to download ESB tooling 5.0 he servo 5.0 from the ESB product page shown here from WSO2 ESB Training. If you are to install a speed tool in using report you need Eclipse master distribution downloaded and installed. Then let see how we can install you ESB tooling using online PTO repository.
WSO2 ESB Training explains How to install ESB tooling using online PTO repository:
- Eclipse mass to distribution go to select install new software and click on add, do you hear the repository URL.
- This URL is the online p2 repository URL and give the name and click on ok
- Select the all components here and click on next
- On text and how to accept the license agreement and click on finish.
- Now it’s installing these patrolling features and select modules and click on ok
- After restart Eclipse now you will see a new menu appeared here the menu bar as developer studio.
- You can click on it on it and select open dashboard.
How to Create Artifacts: WSO2 ESB Training
If you go to the developer studio dashboard you can see the entire developer studio dashboard you can see all the available option to create the ESB artifacts. If first we select and show you the steps to create an API then the steps to create a registry resource.
- First select the ESB config project then click on next and give the project the name here click on next keep the default
- as it is and clicks on the finish, now you can see the project
- we created and click the right click on API new rest area click on next
- next cue DBA name here and context which is our project and click on finish.
Now we created the API if have a look, the sauce view. We can see the configuration for the API displayed here. We are going to back design if I open the mediator step you can see all available mediators are listing here first. First I will add the same mediator to the created API. Then I will add an endpoint to the same mediator. It is my endpoint if we go to the property section, we can see relevant properties are there. now you can see relevant properties below by default the get methods is in group state. Now done with API configuration and saving this now go to the source view of the create up feel you can see the API configuration here.
Creating Composite Application: WSO2 ESB Training
Create the composite application project, which use to package ESB artifact and also to deploy those as a single file. This enhances reusability and maintainability of ESB artifacts. Go back to the dashboard select composite application project. That project we called it CAR, so I am selecting that option and give some name. You can see the dependencies ESP solution project.
Overview of WSO2 ESB Training:
WSO2 ESB5 consists of 3 main components
You can use the ESB tooling component which is built of Eclipse to develop debug and deploy your services. If you can use the ESB analytics components which are built on top of the device or to dash products to trace and monitor your services. So let’s go and develop our first hello world integration service using the WSO2 ESB tooling component. So once you start the tooling component. So you go to the developer studio main page. Where you can see set of integration project types.
The ESB project solution first step gives the name of this project as echo ESB project. In the ESB solution, we have four types of projects created by default. The first one is the ESB configuration project then there is a register resources project. There is a connect exporter project and a composite application project. In this scenario, I will be one day using ESB config project and a composite application. If you can give your preferred proof id and artifact id I will keep them. It is after filling and click and finish, so once I created this project it is created to configuration project. the first one is an ESB project and the next one is the composite application project.
Create a sample proxy service: WSO2 ESB Training
The sample proxy service we will create a custom proxy for this demonstration in other so once you click on create it will create a proxy service. So then to create an echo service you need to include the respond mediator, so it will basically respond or echo back whatever. the message receives from the client so for the tracing purposes, I will add another mediator log mediator to the proxy service. So once I add all these two mediators I am done with my echo service so in this case, I am going to enable.
So in this use case I am going to monitor the service once it is deployed into the WSO2 ESB Training for that I need to enable the tracing of messages for this particular service ok now. I have created my proxy server and I have enabled tracing and study 6 for the service. I need to create a composite application which includes the proxy service which I already created ok now I have created my website application. Now I am going to the ESB server and start the ESB cell so in this case, I have the wso2 enterprise service bus online training analytics component and the wso2 enterprise service bus runtime component. I will first start to be a little component and also the WSO2 ESB runtime component. So before starting the runtime component enable the statistics and Tracy will he cell. After open synapse node properties file. So in this file, there is a section to enable statistics and tracing. So you can see we have mediation flow statistics enable parameter may it true. And also you can enable the payload collection from this parameter and also you can enable properties collection by enabling this particular parameter. The statistics collect parameter also can enable.
This will make sure that it will collect statistics for all the artifacts expect you of either enable at that fact level or not this is the only configuration. We need to do at the wso2 enterprise service bus runtime so now the wso2 enterprise service bus online training a little cell is already started. Now if going to start the ESB runtime. After starting the WSO2 ESB Training runtime, we can direct deploy my service this runtime. now the server is started so we will be going to create a new server.
