Issue with database connection pool

[prashantonkar]

I have created multiple data sources through sling:OsgiConfig nodes in the run mode configuration.

I can also see these configurations in configurations manager screen.

I am trying to get database connection using below code:

@Reference
    private DataSourcePool dspService;
....
getConnection(){
     DataSource ds = (DataSource) dspService.getDataSource("abc-xyz");
.....
}

I get an error:

com.day.commons.datasource.poolservice.DataSourceNotFoundException: No data source found with name 'abc-xyz' (after asking 0 providers).

If I open the config manager and save the configurations again, connection works successfully. Why is the behavior shown ?

I tried the following solution.

I created a bundle activator and put the code to programmatically update the configurations

ServiceReference serviceRef = context
.getServiceReference(ConfigurationAdmin.class.getName());
ConfigurationAdmin configAdmin = (ConfigurationAdmin) context
.getService(serviceRef);
String filter = '(' + ConfigurationAdmin.SERVICE_FACTORYPID + '='
+ "com.day.commons.datasource.jdbcpool.JdbcPoolService"
+ ')';
Configuration[] allLoggerConfigs = configAdmin
.listConfigurations(filter);
for (Configuration conf : allLoggerConfigs) {
conf.setBundleLocation(conf.getBundleLocation());
Dictionary prop = conf.getProperties();
log.info("Initializing : " + prop.get("datasource.name"));
conf.update(prop);

But I think the above is not required and should work without the above code. Please help
