Hi all - looking for a bit of help or direction.
I'm having a bit of a problem trying to bind an Object-type implementing Referenceable to JNDI. There's a requirement here that the object can't be saved in a Serialized way, it needs to be a reference so it's kept alive in memory even after I've disconnected to it.
Hopefully someone can help - i've tried to lay it out below as simply as I can.
-> I've got an Object-Type that implements Referenceable (I've implemented the getReference() function appropriately I hope:
public Reference getReference(){
|
| // the ObjectTreeRefAddr is a class I wrote implementing RefAddr
| // so that I can store away a whole "live" object, and not just String props
| ObjectTreeRefAddr refAddr = new ObjectTreeRefAddr("objecttree", this);
| Reference myRef = new Reference(ObjectTree.class.getName(),
| refAddr,
| ObjectTreeFactory.class.getName(), null);
| // debug-code, below will return the Reference correctly
| ObjectTreeRefAddr newRefAddr = (ObjectTreeRefAddr)myRef.get(0);
|
| return myRef;
| }
I've also created the Factory for this ObjectTree class but the problem i'm having is when I go to Bind(), not really at the Lookup part yet.
// Following code breaks...
| context.bind("objecttree", myObj);
|
| // ...With the following error:
| /* Problem binding:
| javax.naming.CommunicationException [Root exception is java.rmi.MarshalException: error marshalling arguments; nested exception is:
| java.io.NotSerializableException: com.company.work.ObjectTree]
| */
I think (hope) i'm doing this correctly - it binds just fine if I use a StringRefAddr instead of trying to bind the Object Reference. I'm also hoping that this is even possible. Again it's got to be a Referenceable and not a Serializable (a forced decision).
Thanks, in advance, to anyone that could offer suggestions.
