Dear all,
Thank you for your answers! I found problem and fix this. The way to fix
is below:
When using Web Application Listener Template, Netbeans generates code:
public class MyOwnEventListener implements ServletContextListener {
public void contextInitialized(ServletContextEvent sce) {
throw new UnsupportedOperationException("Not supported yet.");
}
public void contextDestroyed(ServletContextEvent sce) {
throw new UnsupportedOperationException("Not supported yet.");
}
}
There are 2 ways to fix this problem:
1) remove throw
or
2) throw must be used in try catch block:
try {
}catch (Exception e){
throw new UnsupportedOperationException("Not supported yet.");
}
It works fine when I apply one of two above solution!
Have a nice day
Best regards,
Mrs.Nga
