5.1 Reflective Java This protocol =-=[26]-=-[27] makes message sends reflective. A message sent to an object of a reflective class is redirected to a metaobject. That is made without any change in the Java language, its compiler, or in the Virt...Wu, Z. and S. Schwiderski, ...
I'm sort of looking for some collaboration here. I know that java.io.File is cannot be made writeable after it's been setReadOnly(); So I made a class RWFile (Read-Write-File) that extends java.io.File and adds one method: boolean setWriteable(). I have already implemented this fo...

Java IO Manager - a class designed for improving the usage of the Input/Output in your Java programs, making your life easier - Javinator9889/IOManager
Objects are ussually created in the young area. Once an object has survived a couple of GC cycles it is tenured to the old generation. (The JRockit and IBM JVM make exceptions for very large objects, as I will explain later.) After the application has completed its initial startup phase...
If you got both, your annotated bean and the listener in yourweb.xml, you will typically have another problem:how to use a session scoped bean in a normal (not session scoped) service? To solve this problem, Spring provides a proxy mechanism. This means Spring can wire a proxy with the...
