There is no method to get the size in bytes. You can only approximate. The admin bean used by the JCSAdmin.jsp writes the objects to a counting output stream to get a rough idea of how much memory a region is using, but there is no way to configure the cache to limit the size in bytes of a region.
There is no way to accurately determine how much memory an object takes, at least no way to get close that would not be too expensive to use. We could put some limits on the cache using the memory size fuctions available in the System class in jdk1.4, but this still wouldn't give you the control you want.
