He configurado algunos programadores en la primavera. Cuando trato de iniciar mi aplicación web, arroja el siguiente error y se detiene. Mi aplicación no se ha iniciado realmente. Mi planificador se ve así también cuando i cierre Tomcat un poco de hilo de cuarzo no se apaganError al iniciar/detener Tomcat 6.0.29

SEVERE: The web application [/] registered the JBDC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

SEVERE: The web application [/] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [[email protected]]) and a value of type [org.apache.cxf.bus.CXFBusImpl] (value [[email protected]]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
he implementado oyente:
import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import org.quartz.SchedulerException;
import org.quartz.impl.StdSchedulerFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class QuartzServletContextListener implements ServletContextListener {
final Logger log = LoggerFactory.getLogger(QuartzServletContextListener.class);
public static final String QUARTZ_FACTORY_KEY =
"org.quartz.impl.StdSchedulerFactory.KEY";
private ServletContext ctx = null;
private StdSchedulerFactory factory = null;
public void contextInitialized(ServletContextEvent sce) {
ctx = sce.getServletContext();
try {
factory = new StdSchedulerFactory();
// Start the scheduler now
factory.getScheduler().start();
log.info("Storing QuartzScheduler Factory at"
+ QUARTZ_FACTORY_KEY);
ctx.setAttribute(QUARTZ_FACTORY_KEY, factory);
} catch (Exception ex) {
log.error("Quartz failed to initialize", ex);
}
}
public void contextDestroyed(ServletContextEvent sce) {
try {
log.info("shutting down");
factory.getScheduler().shutdown();
Thread.sleep(1000);
} catch (InterruptedException ex) {
log.error("Quartz failed to shutdown", ex);
} catch (SchedulerException ex) {
log.error("Quartz failed to shutdown", ex);
}
}
}
Y añadió en web.xml
<listener>
<listener-class>xx.yy.QuartzServletContextListener</listener-class>
</listener>
Cuando intento utilizar shutdown.sh que puede en sí todavía algunos hilos proceso java activo y Tomcat activo.
También mencionar que tengo un poco de 3 a 4 programadores de trabajo diferente como se mencionó anteriormente en el contexto de aplicación.
