8. HI Lokesh, you explain this concurrency topics in a great way, but I cannot find synchronized volatile explained by you.

9. i want know to use apache library in our website it requires some licence if yes then how please reply fast

   • No license is needed.

10. Hi Lokesh,
    for some reason your singleton page captcha is not working well, so I post my comment here.
    In your Lazy initialization part, you named the double checked version implenetation as EagerSingleton.

    public class EagerSingleton {
        private static volatile EagerSingleton instance = null;
     
        // private constructor
        private EagerSingleton() {
        }
     
        public static EagerSingleton getInstance() {
            if (instance == null) {
                synchronized (EagerSingleton.class) {
                    // Double check
                    if (instance == null) {
                        instance = new EagerSingleton();
                    }
                }
            }
            return instance;
        }
    }
    

    Since its not an Eager initialization i would recommand changing the class name. Apart from that I like very much your blog.

    • I will check it. And thanks for letting me know about captcha thing. I will fix it.

11. hi lokesh..I want to uninstall oracle10gxe.while deleting msvcr71.dll and oci.dll it is showing an error msg that “the action can’t be completed because it is open in windows explorer”.please suggest me how i will delete msvcr71.dll and oci.dll??

    • Restart the system and kill all oracle processes from windows services or task manager. You should be able to delete all files now.

12. Just a feedback,… U r awesome! Its a great learning experience for all java developers.

14. hi

    do you have any working examples of spring security using
    KeyBasedPersistenceTokenService?

    My requirement is to use json/rest architecture with Spring MVC 3 annotations, spring security with token exchange.

    thanks

    • I will work on it.

    • yeah,I also want a same example where spring security has been implemented with OAuth protocol.OAuth 2.0 is been used by all sites(FB,G+,ebay) to grant permission 3rd party users to use their data.

      I’m sure Lokesh will help on this.It would be helpful for him also.

15. great job.. really good information.. all at one place..

16. can u explain these problem clearly

    2) If the class contains members of any class type then only the object references to those members are copied and hence the member references in both the original object as well as the cloned object refer to the same object.
