Is it possible access a database within osgi bundle's start method?
public void start(BundleContext context) throws Exception {
ModelService modelService = new ModelService();
context.registerService(ModelService.class.getName(),
modelService, null);
* MLAlgorithmConfiguration mlAlgorithmConfiguration = new
MLAlgorithmConfiguration();
mlAlgorithmConfiguration.loadMLAlgorithmConfigurations();*
logger.info("Model service started");
}
loadMLConfigurations loads some default values to a database. Adding bold
lettered lines throws following exception
INFO {org.wso2.carbon.ml.dataset.DatasetServiceActivator} - Dataset
service started
[2014-11-13 16:48:49,589] ERROR {org.wso2.carbon.ml.model.DatabaseHandler}
