Unfortunately, a serialized
graph of interconnected objects can only be accessed as a whole; it’s impossible to
retrieve any data from the stream without deserializing the entire stream. Thus, the
resulting byte-stream must be considered unsuitable for arbitrary search or aggregation.
It isn’t even possible to access or update a single object or subgraph independently.
Loading and overwriting an entire object graph in each transaction is
no option for systems designed to support high concurrency.
Clearly, given current technology, serialization is inadequate as a persistence
mechanism for high concurrency web and enterprise applications. It has a particular
niche as a suitable persistence mechanism for desktop applications.
Your quote in your signature says it all. I don't understand what you are asking.
I am working on application...explanation you can see in swing & jdbc section.
When i run above code..then only last object of array (if array of 9 then 8th) avoid overlapping when other try to overlap on it....
Same time when smaller Array value jpanel dragged on higher value jpanel then it goes behind not upside.(eg if i drag 0th panel on 1st panel from array of 9, then it move from upside of 1st panel...
but when i drag any other panel to 0th panel then it goes behind 0th panel...i dont no why...& also not know how to avid it...all jpanels should move upside of other panels when they drag here & there.
Again, I don't understand what the problem is. It doesn't matter that you want drag and drop in Swing. Do you have a specific question that you are having a problem with? I cannot see what that would be in your post. Just break it down to the simplest part and we can work on it little by little.
