Message counter

[Pjotr <de...@gmx.net>]

Hi,

first of all I have to say I'm a beginner with ActiveMQ / Camel so please
have mercy on me 

I would like to store ActiveMQ messages in the filesystem with a specific
naming scheme [date]-[id]-[counter] 

Currently I got date and Id working - but I found no way to set a counter
:confused:

ActiveMQ 5.3 camel.xml:

...
<when>
<xpath>/event/qualifier = 'foo'</xpath>
<setHeader headerName="tmp_id"><xpath>/event/id</xpath></setHeader>
<to
uri="file://C:/tmp/?fileName=${date:now:yyyyMMddHHmmssSSS}-${in.headers.tmp_id}-${???}.xml"
/>
</when>
...

Any ideas??

Hi,

are there other possibilities with functions that directly come along with
Camel (ActiveMQ) ?

If not I'll do it that way you described it - but if it was possible to do
it with included functionality, I would prefer this. (Because I assume the
stability and reliability "out-of-the-box" is better, if there are less
dependencies... I guess...)

But thanks a lot for your fast response (and the good idea)!

Hi

You can use a POJO/bean which returns the counter value.

See the last example here
http://camel.apache.org/file-language.html

Then all you do is defining your bean in spring

<bean id="myCounter" class="..."/>

And then you invoke the method on the bean, as shown in that last example.
