Example: Using the XPathXmlStringWriter ComponentLocate this document in the navigation structure

The XPathXmlStringWriter component writes XML formatted data using XPath rules, and is used with the FileSink component. Associate the AsapSource component, which reads data from the Server and passes it to FileSink, with the FileSink component, which writes out the XML data using XPathXmlStringWriter.

Prerequisites

The cluster database stores configuration information. Ensure that the cluster is running, so that the adapter can interact with the projects on the cluster.

Procedure

  1. Set the user name and password in the example environment:
    Operating System Step
    Windows
    1. Edit the set_example_env.bat script
    2. Set the ADAPTER_EXAMPLE_USERNAME and ADAPTER_EXAMPLE_PASSWORD variables to the desired user name/password combination.
    3. If SSL is enabled, set ADAPTER_EXAMPLE_CLUSTER_NODE_PROTOCOL to esps. If it is disabled, set it to esp.
    UNIX
    1. Edit the set_example_env.sh script
    2. Set the ADAPTER_EXAMPLE_USERNAME and ADAPTER_EXAMPLE_PASSWORD variables to the desired user name/password combination.
    3. If SSL is enabled, set ADAPTER_EXAMPLE_CLUSTER_NODE_PROTOCOL to esps. If it is disabled, set it to esp.
  2. Start SAP Event Stream Processor.
    Operating System Step
    Windows Open a command window:
    1. Start the cluster:

      start_server_cluster.bat

    2. Add project to the cluster, and start it on the cluster:

      start_project.bat
    UNIX Open a terminal window:
    1. Start the cluster:

      ./start_server_cluster.sh

    2. Start the project on the cluster:

      ./start_project.sh
  3. Start streamingsubscribe to subscribe to the project that is running on the cluster.
    Operating System Step
    Windows Open a command window and enter:

    streamingsubscribe.bat
    UNIX Open a terminal window and enter:

    ./streamingsubscribe.sh
  4. Start the AsapSource and FileSink (with XPathXmlStringWriter) components.
    Operating System Step
    UNIX Open a terminal window and enter:

    ./XPathXmlStringWriter.sh
    Windows Open a command window and enter:

    XPathXmlStringWriter.bat
  5. Upload data from the esp_insert.txt file to the Server.
    Operating System Step
    UNIX Open a terminal window and enter:

    ./streamingupload.sh
    Windows Open a command window and enter:

    streamingupload.bat
