Scopes
The error handler is scoped as either
- global
- per route specific
- or policy based (this applies for transactional exchanges only)
The following example shows how you can register a global error handler (in this case using the logging handler)

Spring based configuration
Available as of Camel 1.4
| Info | ||
|---|---|---|
| ||
The error handler is configured a bit differently in Java DSL and Spring DSL. Spring DSL relies more on standard Spring bean configuration whereas Java DSL uses fluent builders. |
In Camel 1.4 the error handler can be configured as a spring bean and referenced as eitherscoped in:
- global (the camelContext tag)
- per route (the route tag)
- per policy (the policy tag)
