I want to access same persistet object from two different applications.
any suggestions on how to do it ?

If you haven't already looked at the Developer's Guides Check out Volume 2, page 88 Blackberry persistent storage. As long as both applications know the correct ID they can each read the data. If you want to share runtime data, look at page 133. Unfortunately these APIs required signing the binary, but I find them useful.

Thanks hrbuckley,
with the help u provided ,I managed to get the shared objects,
but I am not able to retrieve the data from userdefined class objects.

suppose I want to share the vector which contains ABC class's Object

code which put's the data on runtimeshare

class ABC
{
   String msg;
}
class ---{
RuntimeStore store = RuntimeStore.getRuntimeStore();  
        ABC abc=new ABC();
        abc.msg = "Hi";
        Vector vec=new Vector();
        vec.addElement(abc);
        long ID = 0x9e281cf2762efac3L;
        // put() throws an IllegalArgumentException if an object with the same ID exists.
        try {
        store.put( ID, vec);
        } catch(IllegalArgumentException e) {
        // Handle exception - an object with the same ID exists.
        }

}

Code which retrieves the data from runtimeshare

class ABC
{
   String msg;
}
class ---{
 RuntimeStore store = RuntimeStore.getRuntimeStore();
             // Create an object and a unique number to identify the object.        
        long ID = 0x9e281cf2762efac3L;         
        try {
        // get() returns the objectm with the specified ID if it exists; null
        // otherwise.
         Vector vec= (Vector)store.get(ID)
       if(vec.size()>0)
         ABC abc=(ABC)vec.elementAt(0);//gives Error java.lang.ClassCastException

}

can anybody tell me how to solve this Problem?

[Skipper_Joe]

as far as I remember, class ABC should implement interface Persistable

Thanks Skipper_Joe,
I even tried with persistent object Iam getting the same error,but I can
able to get and retrieve the value fo String variable object.

I had an Application1 which puts the data on runtimeshare contains ABC class and another Application2 which receives the data form share also contains the same ABC class,
App1's ABC class doesnot match with App2's ABC class even it contains the same fields .
Is there any solution to solve the above problem?

[Skipper_Joe]

You can't use different classes. 2 different classes are not considered the same even if they have the same set of fields. You need to use the same class definition in both applications.
For example, you can create separate library, which contains definition of class ABS and use it in both App1 and App2.
