Component

The jcr component allows you to add/read

nodes

to/from
...
a
...
JCR
...
compliant
...
content
...
repository
...
(for
...
example,
...
...

)
...
with
...
its
...
producer,
...
or
...
register
...
an
...
EventListener
...
with
...
the
...
consumer.

From Camel 2.10 *onwards you can use consumer as an EventListener in JCR or a producer to read a node by identifier. |
