read config from system environment

[soltani...@gmail.com]

Hello,

I want to read the IP address from the system environment in the following file, which is related to jPOS.

In other words, I want to set the values in the operating system environment variables and have them applied automatically in the jPOS configuration file.

<?xml version="1.0" ?>
<channel-adaptor name='bank1-channel-adaptor'
 class="org.jpos.q2.iso.ChannelAdaptor" logger="Q2">
<channel name="nelito-channel"
 class="org.jpos.iso.channel.ASCIIChannel" logger="Q2"
 packager="com.en.datavsn.EFTswitch.atm.common.ShetabISO87APackager">
<property name="host" value="${HOST}" />
<property name="port" value="9999" />
</channel>
<!--Code Added for Echo Message between Switch and HIF wrt Issue#4373 on 12-Feb-2014 -->
<in>bank1-send</in>
<out>bank1-receive</out>
<space>tspace:default</space>
<reconnect-delay>30000</reconnect-delay>
</channel-adaptor>

Thanks

Hi!

Before starting the jPOS application, make sure to set and export the environment variable:

$ export HOST=<the-ip-of-your-host>

After setting the variable, you can start the application:

$ ./q2

For more details, please refer to the documentation: https://jpos.org/docs/tutorial/qbean/configuration/#environments.

Best regards,

I start jPOS inside Oracle WebLogic Server.

My goal is to deploy the application on Kubernetes and have the configuration files loaded from HashiCorp Vault.

Do you have a suitable solution for this?

Alternatively, if the configuration can also be read from the operating system environment variables, that would solve my problem as well.
Thanks

Singleton
@Startup
public class JposService {

private Q2 q2;
private Logger logger = LoggerFactory.getLogger(JposService.class.getName());
public static final String SWITCH_CONFIG_PATH = System.getenv().get("SWITCH_CONFIG_PATH");

@PostConstruct
private void inti() {
q2 = new Q2(new String[]{"-d", SWITCH_CONFIG_PATH + "/q2/deploy"});
startQ2();
}

public void startQ2() {

q2.start();
logger.info("Q2 has been started");
}

@PreDestroy
private void preDestroy() {
q2.shutdown();
logger.info("Q2 has been stopped");
}
}
