Example: Using the XPathXmlStreamReader Component

XPathXmlStreamReader parses a single row of data from a single XML input file and sends the row to the ESP project. Then, the esp-subscribe.sh (Linux, Solaris) or esp-subscribe.bat (Windows) file reads the row and displays it in the console.

Prerequisites

Set JAVA_HOME:

On Linux or Solaris, export JAVA_HOME=$ESP_HOME/lib/jre
On Windows, set JAVA_HOME=%ESP_HOME%\lib\jre

Task

Set the user name and password in the example environment:

Operating System	Step
Windows	Edit the `set_example_env.bat` script Set the ADAPTER_EXAMPLE_USERNAME and ADAPTER_EXAMPLE_PASSWORD variables to `sybase`.
UNIX	Edit the `set_example_env.sh` script Set the ADAPTER_EXAMPLE_USERNAME and ADAPTER_EXAMPLE_PASSWORD variables to `sybase`.

On Windows only, modify the set_example_env.bat file:
- Remove the line:
```
call "%~dp0..\..\..\set_adapter_env.bat"
```
- Add the lines:
```
call set_example_env.bat
call %ADAPTER_EXAMPLE_DEPTH%\set_adapter_env.bat
```
In the XPathXmlStreamReader.props file, append sybase to the following lines to set the user and password variables:
```
adapter.ASAPSINK.User = 
adapter.ASAPSINK.Passwd = 
```

Run the example:

Operating System	Step
UNIX	Open a terminal window and run `./start_server_cluster.sh` to start the server cluster. In a second terminal window, run `./start_project.sh` to start the project. In the same terminal window, run `./esp-subscribe.sh` to subscribe to the project running on the cluster. In a third terminal window, run `./XPathXmlStreamReader.sh` to start the FilePollSource (with XPathXmlStreamReader) and AsapSink components.
Windows	Open a command window and run `start_server_cluster.bat` to start the server cluster. In a second command window run `start_project.bat` to start the project. In the same command window, run `esp-subscribe.bat` to subscribe to the project running on the cluster. In a third command window, run `XPathXmlStreamReader.bat` to start the FilePollSource (with XPathXmlStreamReader) and AsapSink components.

Operating System

Step

UNIX

Open a terminal window and run ./start_server_cluster.sh to start the server cluster.
In a second terminal window, run ./start_project.sh to start the project.
In the same terminal window, run ./esp-subscribe.sh to subscribe to the project running on the cluster.
In a third terminal window, run ./XPathXmlStreamReader.sh to start the FilePollSource (with XPathXmlStreamReader) and AsapSink components.

Windows

Open a command window and run start_server_cluster.bat to start the server cluster.
In a second command window run start_project.bat to start the project.
In the same command window, run esp-subscribe.bat to subscribe to the project running on the cluster.
In a third command window, run XPathXmlStreamReader.bat to start the FilePollSource (with XPathXmlStreamReader) and AsapSink components.

The example runs and the output displays in the second terminal/command window.
