In this sample, the TIBCO StreamBase® Web Input adapter and TIBCO StreamBase® Web Output adapter are used to enqueue and dequeue data using REST input requests and WebSocket clients connected for output.
When this sample is started, a web server is created on port 10090 by default and will contain a webpage at the root which lists all available web input and output URLs along with their associated schemas.
In StreamBase Studio, import this sample with the following steps:
From the top-level menu, select> .
restto narrow the list of options.
Select REST Web Input and Web Socket Stream Output from the StreamBase Standard Adapters category.
StreamBase Studio creates a single project containing the sample files.
In the Project Explorer view, open the sample you just loaded.
If you see red marks on a project folder, wait a moment for the project to load its features.
If the red marks do not resolve themselves after a minute, select the project, right-click, and select Maven> from the context menu.
