Excerpts from “Spring in Production” whitepaper.

The Spring Framework and Spring Portfolio products are used in production in mission-critical applications all over the world and in every kind of industry.

For example, almost all of the inter-bank transfers in the United Kingdom are handled by a company called Voca. They process over 80 million items on a peak day, handle bill payments for over 70% of the UK population, and handle salary payments for over 90%. Voca are proud of the fact that they have never lost a single payment. These transfers are powered by Spring.
For example, HSBC recently took out a support contract with SpringSource to support their mission-critical use of Spring in production applications.
For example, 25% of the world’s cargo movement through port and intermodal facilities is managed through a Spring-powered application built by Navis.

Good to know that Spring looks to be here to stay. It’s a vastly superior framework compared to plain-vanilla JEE.
