I have a need to integrate my stand-alone Spring web application with 2 other systems (including COBOL mainframe) and was wondering if Camel can do more than simply serve as a tool for building mainframe services. For example, I would like to use Camel to serve as the underlying framework (running inside a Spring App Context ) so that I can avoid a bunch of Java code (services, DTOs, entities, etc.) written by various hotshot Spring developers.
What EIPs are relevant here since this is around integrating a Web App with a mainframe in real-time while maintaining integrity of data in both systems.

#Current Situation:
I currently have an existing web application that is running stand-alone without integration to any other systems.
The layers & technologies that have been used are:
- UI layer: GWT & ExtGWT
- Server-side layer: GWT RPC endpoints backed by POJO components running inside Spring 2.5.6 app context.
- Persistence layer: JPA entities & DAOs with Hibernate as the provider (still using HibernateTemplate as the dialect rather than pure JPA API).
- Database: DB2 (immaterial to anything meaningful except JDBC drivers).

#Target Situation (including real-time integration with mainframe):
- UI layer: no change
- Server-side layer: Use Camel as the provider of "flows/services" that are called after all business logic code has been executed (triggered either by a user request or system event) and known actions need to be taken. These flows are transactional in nature wherein the flows need to update the mainframe (by invoking real-time CICS programs) and update the Web App Database if the mainframe request is successful.

Achieving all this using basic Spring framework or even Spring Integration is tedious, error-prone and difficult to maintain & test.

How can I use Camel to serve the web requests and perform the transactional integration tasks as well?

Let me know if this is post is longer than it should be and I will happily comply and break it up.
