HI Folks,


I am newbie to JBOSS World .

I am trying to migrate my application which has Seam, Ejb, Struts, JSF and JMS from JBoss 4.2.0 to Jboss 5.1.0

Following are my quetsions
  • Can i call EJB exposed in JBOSS 5.1.0 from JBOSS 4.2.0 ?, if not is there any work around like having jars will help them


  • Can i consume EJB exposed in JBOSS 4.2.0 from JBOSS 5.1 ?, if not is there any work around like having jars will help them


  • I had hard time in finding the port where EJB is exposed in JBOSS 5.1.0, I would like to know name of file.


  • can present consumer of JBOSS 4.2.0 from standalone process call EJB exposed in JBOSS 5.1.0?


  • Thanks in advance.

    Hi Folks,

    I would like to give seminar on Restful Services using the Jersey (or) Spring Jersey.

    Could someone guide me some advanced and intersting concepts, which will used for techies who attend the session?

    Some of the concepts which come to my mind

    Reperesting resources as hyperlinks HATEOAS

    Authentication

    Thanks in advance.

    Scenraio is something of this sort ...

    In our project we have couple of Spring beans save POJO ( service layer which talks to dao ...)

    During the spring context startup, i would like to expose configured beans as Restful services ...

    As @Lance said, i need to tweak or extend or customise the spring loading stuff to acieve the same ...

    Any examples or WIKI or idea would be really appreciated.

    Hi Folks,

    I would like introduce some dynamic cabability of exposing the spring bean as restful services

    scenario is

    1) i need to read the list of spring bean id's from fileat runtime( or during the loading time of web app)
    2) based on bean id's i fetch from step 1 , i need to some how expose the beans as restful services

    is there a way to acieve the same ?

    Hi ,

    I had written class which extends “AbstractTransactionalSpringContextTests” for testing my beans instantiated via spring framework .

    I had annotated all java classes eligible for spring to load with @Service,@Autowire,@Qualifier in XML along with component scanning with pkg which has annotated classes .

    Issue I face when I tried to inject properties (with autowire ) for classes which is not apart of component scanning ( I purposefully left those packages in scanning, as I am not interested in testing / loading the class)
    Spring does because required is set to true by default in Autowired class.
    Hence to resolve this issue , I added “default-lazy-init="true" in xml , which resolved my issue .

    Even with “AbstractTransactionalSpringContextTests” we have that option using “setDependencyCheck(false) ".it is not working as expected .

    I prefer way to do in test class level , rather than changing xml ( FYI going fwd we would like to use same XML for application and testing )

    With @Autowired it perfectly works with abstract classes ,Thanks for info

    is there way to create the virtual abstract bean



    in above XML case ,we really dont have real abstract class in java ,instead we call hibernamteTemplate (aka sampleDao )

    Thanks in advance .

    Hi Mark ,

    Thanks for your kind reply .

    We construct abstract bean like

    How this can be changed using annotation ? can it be done if so how ?


    @Scope - i will check this annotation .

    Can you eleborate on this please "I can create the pojo Factory as a bean, then inject it in places that can call the factory method when it needs those objects. "



    Thanks in advance .

    HI Ranchers !!!

    I am working on migration of Spring XML to Spring Annotaions , Since we have limitation we have to use featured upto spring 2.5.6

    As per my idea , we cant achieve all things that we do via XML

    Few Limitations with Annotations
    -------------------------------------

    1) cant declare bean (pojo) as abstract , as we do in XML
    2) Factory way of instantiating beans
    3) Lazy loading
    4) Declaring bean as prototype (or) non prototype
    5) Injecting collections to bean

    Let me know if we have any work around of above mentioned issues .

    Could somebody point out link , where i can see spring annotations limitations .

    Thanks in advance

    Do I need to make my HashMap class as protected then?



    How can you do this ? ( will you extends Hashmap bh any chance if so you do ,but for your requirement it doesnt makes sense for that effort ) .



    In above scenario makes sure while you are retriving from DB , make all other threads in wait stage , else those threads will get the satle data or null values .

    Hope it helps .

    Concepts to use
    Singleton , In memory Caching , Threading ...

    What you are doing is concept called "Caching In Memory" .

    If you are using in Web Appln , store this hashmap instance in Application scope .

    In standalone , as far your instance is alive you have data in hashmap , write the code in such as way , none of other class have access to modify values in hashmap .
