Rmi service pooling

Question

I have a rmi service that searches for products that are stored in a flat file system. The code sets up a key and then sequentially reads through the file returning data objects (if they match the required criteria) via a call back method. Due to what the method has to do I have had to make the method synchronized. My problem is that while this search is going on no other client can make a call to that particular service. Does anybody know a way round this as I have spent all day searching the internet for an answer. Please help

Answer 1

The main point of synchronizing is to "single thread" or "lock"; that is, only allow one thread at a time access to the objects.
Often it is not the method itself that needs locking but selective code within the method. In such a case, you only need to lock that selective code with a synchronized (Object) {} statement rather than a synchronized modifier on the method. There are many examples on how to do this in the archive.
