The

db4o:
...
component
...
allows

you
...
to
...
work
...
with
...
...
NoSQL
...
database.
...
The
...
camel-db4o
...
library
...
is
...
provided
...
by
...
the
...
...
...
project
...
which
...
hosts

all
...
*GPL

related
...
components

Sending

to

the

endpoint
...
Sending
...
POJO
...
object
...
to
...
the
...
db4o
...
endpoint
...
adds
...
and
...
saves
...
object
...
into
...
the
...
database.
...
The
...
body
...
of
...
the
...
message
...
is
...
assumed
...
to
...
be
...
a
...
POJO
...
that
...
has
...
to
...
be
...
saved
...
into
...
the
...
db40
...
database
...
store.
...
Consuming
...
from
...
the
...
endpoint
...
Consuming
...
messages
...
removes
...
(or
...
updates)
...
POJO
...
objects
...
in
...
the
...
database.
...
This
...
allows
...
you
...
to
...
use
...
a
...
Db4o
...
datastore
...
as
...
a
...
logical
...
queue;
...
consumers
...
take
...
messages
...
from
...
the
...
queue
...
and
...
then
...
delete
...
them
...
to
...
logically
...
remove
...
them
...
from
...
the
...
queue.
...
If
...
you
...
do
...
not
...
wish
...
to
...
delete
...
the
...
object
...
when
...
it
...
has
...
been
...
processed,
...
you
...
can
...
specify
...
consumeDelete=false
...
on
...
the
...
URI.
...
This
...
will
...
result
...
in
...
the
...
POJO
...
being
...
processed
...
each
...
poll.
