Exception handling for camel-ftp
Hi,
I am using camel-ftp (2.10.4) in my camel application(camel-route).
If the ftp related error occured like wrong credential or incorrect IP then
it throws
"org.apache.camel.component.file.GenericFileOperationFailedException"
exception.
I want to retry 3 times if FTP error occured, for that i added below code in
route file.
<onException>
<exception>org.apache.camel.component.file.GenericFileOperationFailedException</exception>
<redeliveryPolicy maximumRedeliveries="3" redeliveryDelay="300000" />
<onException>
But what happen here I am also using <from uri="file:src/target" /> in same
file and in someof the case this code also throws the same
"org.apache.camel.component.file.GenericFileOperationFailedException"
exception.
So my question is how do i differe both exception ? I want to retry if FTP
error occrrued else not.

Its the FTP server that returns the errors. So you should go look for
the FTP error codes. There is some standard codes. So google and find
them.
And as said you can use getCode on the exception to get the code, and
use that in your check instead of the error message text.

I can see one more exception now
org.apache.camel.component.file.GenericFileOperationFailedException: File
operation failed: Connection closed without indication
How can I confirm that all exception covered using <onWhen>
Its very difficult for me to find all . Can someone tell me what is the best
way to cover all FTP exception? I don't want to miss any, also don't want to
retry in case of local file error i.e. file:src/target.

Yes I want to do in XML only.
Adding below two lines will cover these two exception. But I am not sure
about other (all) FTP related exception.
Basically I need a list, what all exception will occur in case of FTP used.
So i can add that exception in <onWhen>
org.apache.camel.component.file.GenericFileOperationFailedException: Cannot
connect to <XXX file system location> OR
org.apache.camel.component.file.GenericFileOperationFailedException: Cannot
store file: <XXX file system location>
>>>>>>>>>>>>>>>
<onWhen><simple>${exception.message} contains 'connect to'</simple><onWhen>
<onWhen><simple>${exception.message} contains 'store file'</simple><onWhen>
>>>>>>>>>>>>>>>

Hi
If you have a copy of Camel in Action, then see page 150.
If you want to do in XML then you can possible do
<onWhen><simple>${exception.message} contains 'connect to'</simple><onWhen>
But you can also use a java bean
public static boolean
isConnectError(GenericFileOperationFailedException cause) {
...
}
<bean id="myBean" class="com.foo.MyErrorBean"/>
<onWhen><method ref="myBean" method="isConnectError"/></onWhen>

Thanks clause. Have follow up question.
Currently I see two below exceptions in FTP
org.apache.camel.component.file.GenericFileOperationFailedException: Cannot
connect to <XXX file system location> OR
org.apache.camel.component.file.GenericFileOperationFailedException: Cannot
store file: <XXX file system location>
But I am not sure about which predicate to use in <onWhen> which will make
sure that to retry when FTP exception occurred. I tried few things also
googled but no luck.

You can use <onWhen> in the <onException> and use a predicate to check
if you want to react or not. The GenericFileOperationFailedException
ought to have a getCode / getReason() or something that returns the
FTP error code.
