Subject: What's the Difference between handled(false) and continued(true)
 (and more...)?
MIME-Version: 1.0

With regard to the "onException" Spring DSL, here are my questions based th=
e
following 5 definitions (Example A-E).
Note that I replaced &lt; and &gt; with ( and )

1. What's the difference between handled(false) and continued(true)?
(Example C v.s. D)
According to my experience, only continued(true) will really continue
routing as if the exception has not happend.
handled(false) will break out routing, just like what handled(true) does. I=
s
this normal?

2. Similar to question 1, what's the difference between handled(true) and
continued(false)? (Example B v.s. E)
Should continued(false) also break out the normal routing on exception, jus=
t
like what handled(true) does?

3. A famous book on Camel says "OnException doesn=E2=80=99t handle exceptio=
ns by
default".=20
However, Example A also breaks out normal routing on Exception, just like
what Example B does by my experience.
Is my experience conflicting with the Book's assertion that exception is no=
t
handled by default?

Example A:
       (camel:onException)
            (camel:exception)java.lang.ArithmeticException(/camel:exception=
)
            (camel:process ref=3D"arithmeticExceptionProcessor" /)
       (/camel:onException)

Example B:
       (camel:onException)
            (camel:exception)java.lang.ArithmeticException(/camel:exception=
)
          =20
(camel:handled)(camel:constant)true(/camel:constant)(/camel:handled)
            (camel:process ref=3D"arithmeticExceptionProcessor" /)
       (/camel:onException)
=09  =20
Example C:
       (camel:onException)
            (camel:exception)java.lang.ArithmeticException(/camel:exception=
)
          =20
(camel:handled)(camel:constant)false(/camel:constant)(/camel:handled)
            (camel:process ref=3D"arithmeticExceptionProcessor" /)
       (/camel:onException)

Example D:
       (camel:onException)
            (camel:exception)java.lang.ArithmeticException(/camel:exception=
)
          =20
(camel:continued)(camel:constant)true(/camel:constant)(/camel:continued)
            (camel:process ref=3D"arithmeticExceptionProcessor" /)
       (/camel:onException)
=09  =20
Example E:
       (camel:onException)
            (camel:exception)java.lang.ArithmeticException(/camel:exception=
)
          =20
(camel:continued)(camel:constant)false(/camel:constant)(/camel:continued)
            (camel:process ref=3D"arithmeticExceptionProcessor" /)
       (/camel:onException)
=09 =20
