isue in singleton

[guru prasanth]

Hi,
I have a singleton class which is referred in a jar file.Now the jar file is included in multiple ear file.Let's take an example.
I have singleton class which is present in a singleton.jar and this jar file is copied in 4 different ear/war file.Now my requirement is
this class has to be singleton across multiple appliation.But when iam instatiating across application(.ear) file then it creates a different singleton class.Is there any otherway other than making these ear files referring to single jar file.iam using websphere 6.1

Can you clarify why you wish to avoid loading the class from a single jar, and yet you want multiple applications to access the same singleton/instance of the class. In other words, is there a specific reason why you are packaging a copy of the singleton with each application?

Have you looked at deploying the singleton.jar as a shared library:
