What Class.forName will do while loading drivers? |
 Answer
|
Dynamic loading of Java classes at runtime provides tremendous flexibility in the development of enterprise systems. It provides for the basis of "application servers", and allows even simpler, lighter-weight systems to accomplish some of the same ends. Within Java, dynamic loading is typically achieved by calling the forName method on the class java.lang.Class; however, when Class.forName is naively called from within an Extension, strange errors can occur. This paper describes why those errors occur, and how Java2 provides two facilities, one a modification to the forName syntax, and the other, called the "Thread context ClassLoader", to avoid them. This paper assumes you are passingly familiar with Java Reflection, and have at least a general idea of what Java ClassLoaders are and how they are used within Java code.
It is used to load the jdbc driver dynamically. Without naming of class you can load the driver.
