WSDL basically defines 4 types of Operation type responses. These are enlisted below
- One-way: Receives a message but does not return response.
- Request-Response: Receives a request and return a response.
- Solicit-Response: Sends a request and wait for a response.
- Notification: Sends a message but does not wait for a response.
Among these, Request-Response is the most common operation type.
