The "Try It" tool is a tool available with the WSO2 Carbon that allows you to try out your own Web Services Definition Language (WSDL) or any publicly available WSDL of the document/literal style.

"Try It" provides you with a mechanism to test your WSDL by creating endpoints on-the-fly. It helps to test a WSDL before actually coding it, without the need for a third party WSDL validator tool.


The "Try It" tool does not support relative schema imports and WSDL imports at the moment. We will provide this feature in a future release.

Follow the instructions below to use the "Try It" tool in the WSO2 ESB.

1. Sign in. Enter your user name and password to log on to the ESB Management Console.

2. Click the "Tools" button to access the "Tools" menu.

3. From the "Tools" menu, select "Try It."

4. In the "Enter URL" field, type or paste the location of the WSDL. It may be a local file system path or a web URL.

5. Click the "Try It" button.


If your browser has Pop up-Blocking enabled, you will receive a message saying a pop up was blocked. Allow pop ups for the current domain and try again. The available operations in the given WSDL appears. For operations that take arguments you will see primitive argument type fields. The values specified in these fields will be passed to the operations. For no-argument operations you will only see the button that has the same name as the operation.

6. Click the "Send" button to invoke that service operation. The return value immediately appears in the response textarea.

Two text areas can be seen, each for request and response. You can switch the layout using either "Horizontal" or "Vertical" buttons.

Choosing Endpoints

You can change the endpoint for the service, if there are multiple endpoints. You can also specify a customized endpoint.

1. Click the "Using Endpoint - ...." link.

2. Select a new endpoint from the list.

3. Specify the address of the new endpoint.

Viewing the Service Information

1. To view the information about the service click on the "Service Information" link.

Prioritizing Operations

1. Use the small yellow icon with the plus(+) sign to prioritize operation.

2. The chosen operation is added to the "Priority Operations" section.

This will be useful when you have a lot of operations in the Try It page. Then you can add operations you want into this section and switch among them easily.
