Why do we use frameworks? Why not? We don't need to reinvent the wheel so we take advantage of them when we can. There are already proven frameworks in JAVA such as spring, hibernate, hibernate annotations, JAXB, Java-RPC, struts, JXTA, JUNIT, log4J, JSF, Joone, Jena - Ontology etc. The same variety exists in the area of C++ or C# (.NET) technologies, for example using SSIS, log4Net, ,Net WWF, Net2.0 -Net 3.5. We take advantage of framework solutions for application integrations such as SSIS, BizTalk or BEA AquaLogic.

What does it give you? It provides more time for talent to perform the solution instead of focusing on reinventions. It speeds up the development cycle and improves change management control process with better quality assurance.
