HTTP Output Adapter

Adapter type: httpplugin. The SAP Sybase Event Stream Processor HTTP adapter publishes data from Event Stream Processor to external clients.

The HTTP adapter:

• Control Flow
  The adapter loads its configuration from a file (for example, adapter.xml) and validates it against the adapter schema (httpadapter.xsd), which includes the API-wide controller schema (controller.xsd).
• Message Flow
  The message flow between the adapter and an HTTP client is initiated when the client sends a POST request with the start command in it, and a body consisting of a SQL query, to Event Stream Processor.
• Setting the JAVA_HOME Environment Variable
  Set the JAVA_HOME environment variable to point to the Java directory.
• Configuration
  Configuration information for the HTTP adapter.
• Operation
  You can operate the HTTP Output adapter from the command line.
• Example: Sending, Receiving, and Viewing Data
  Use the working example provided in the adapter distribution to learn how to send a SQL query to the adapter, and receive XML-formatted stream data from Event Stream Processor and view it in a Web browser.
