- Have a bug free built connector zip file to upload to the ESB.
- Have an instance of WSO2 ESB server up and running.
- SOAP UI version 4.5 or above to test the request.
Uploading and enabling the connector in ESB
Assuming you have an up and running instance of the WSO2 ESB server, follow the below steps.
Click on Choose File button and browse the connector zip file you have.
Then click on Upload. Note if the upload is successful, the connector file name will be shown in the list and its status will be marked in red as disabled as shown below.
Click on the Status icon to make it enable.
If you get an error message while uploading the connector zip file saying the upload failed, Don't worry just refresh the page few times and retry. If that is not caused by an error thrown by ESB server, this should work for you.
Also, you may need to wait for few seconds to enable the connector after it is uploaded. Note that if you cannot enable the connector even after few attempts, your connector may have issues, you can observe the ESB server log to check whether any exceptions are thrown. If so, carefully handle them in your connector, then build and upload again.
Creating a proxy and getting the WSDLNow we are done with the connector file and need to create a proxy to map the specific function call that we require to test.
You can observe there are several types of proxies shown as above. You can use Custom Proxy to define your own proxy file.
So, Click on Custom Proxy link and switch to source view from where you can handle the source of the proxy easily.
For the demonstrations purpose I am using the Github connector file and Ill focus on getPullRequest method. An example proxy file is shown below.
Proxy file content:
Click on Save. If you created the proxy with no errors, the proxy file will be listed as shown below.
If you face any error while creating the proxy, fix it and save again.
Now, to get the WSDL, you have to simply click on the WSDL1.1 link of the specific proxy.
Making a request through SOAP UIIn the final step, you can use the above WSDL to create a request and make an API call through the WSO2 ESB
Note that I will show how to create a REST request call since I deal with the Github REST API, You can customize your Proxy and the request in any type that suits your requirement (REST(JSON/XML), SOAP etc)
Create a New REST project in SOAP UI using the above WSDL.
Now build the REST request with the necessary parameter and valid values as shown below. Send the request and observe the output
