Spring-IoC Features

1. Spring Framework
   The Spring Framework comes in the form of ZIP file with the necessary jars, examples etc. The Spring framework can be downloaded from http://www.springframework.org. There will be two zip files one with dependencies and other without. The spring framework with dependencies is larger and includes all dependent libraries. Download Spring framework 1.2.9 without dependency and unzip on the hard disk as spring1.2.9.
             
2. Bean factories support two modes of object
     
   • Singleton: In this case, there?s one shared instance of the object with a particular name, which will be retrieved on lookup. This is the default, and most often used, mode. It?s ideal for the stateless service objects.
   • Prototype or non-singleton: In this case, each retrieval will result in the creation of an independent object. For example, this could be used to allow each caller to have its own distinct object reference.
