If I move logback to classpath and java code run fine with

final Logger logger = LoggerFactory.getLogger(LogbackExample.class);
logger.info("Hello World");

java code:-----
final Logger logger = LoggerFactory.getLogger(LogbackExample.class);
 LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
 JoranConfigurator configurator = new JoranConfigurator();
 lc.reset(); 
configurator.setContext(lc);
 configurator.doConfigure("lib/logback.xml"); 
logger.info("Hello World");

logback.xml:-----
