Spring based configuration

In Camel 1.4 we have introduced the concept of configuration of the error handlers using spring XML configuration. The sample below demonstrates that you can configure transaction error handlers in Spring XML as spring beans. These can then be set as global, per route based or per policy based error handler. The latter has been demonstrated in the samples above. This sample is the database sample configured in Spring XML.

Notice that we have defnined two error handler, one per route. The first route uses the transaction error handler, and the 2nd uses no error handler at all.

The following snippet is the Spring XML configuration to setup the error handlers in pure spring XML:
