Example: Sending a Subscription Request

Send a subscription request to the adapter, and see a stream record from Event Stream Processor in a Web browser.

Prerequisites

Install a Web server (port default is 80), Flash policy server (default is 843), and a Web browser with the Flash plug-in.
SAP recommends that the Web server and the policy server run on the same machine on which the adapter is installed.
If the Web server and policy server are running on a different machine than the one on which the adapter is installed, ensure the ports listed above are open for TCP connections from the machine where the Web browser is running.
Copy the example.swf file from the adapter example directory to the content area of the Web server.
The Flex Server port default is 23456.
The Web browser can be used on the same machine or on a different machine.

Task

Set the user name and password for the adapter:
1. Edit adapter.xml.
2. In the <User> and <Password> elements, enter sybase.

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`.

Edit the start_adapter.sh script.
Set the JAVA_HOME environment variable to the directory where the Java Runtime Environment (JRE) is installed.

Start Event Stream Processor.

Operating System	Step
Windows	Open a command window: Start the example cluster: `start_server_cluster.bat` Add project to the cluster, and start it on the cluster: `start_project.bat`
UNIX	Open a terminal window: Start the example cluster: `./start_server_cluster.sh` Start the project on the cluster: `./start_project.sh`

Start the adapter.

Operating System Step

Windows Open a command window and enter:
start_adapter.bat

UNIX Open a terminal window and enter:
./start_adapter.sh
Wait five to ten seconds for the adapter to initialize.
Upload a stream record.

Operating System Step

UNIX Open a terminal window and enter:
./upload.sh

Windows Open a command window and enter:
upload.bat
Point the Web browser to the example.swf file. For example:
```
http://localhost:80/sybase/example.swf
```

Operating System	Step
Windows	Open a command window and enter: `start_adapter.bat`
UNIX	Open a terminal window and enter: `./start_adapter.sh`

Operating System	Step
UNIX	Open a terminal window and enter: `./upload.sh`
Windows	Open a command window and enter: `upload.bat`

You see this stream record in the browser window:
