Hi
I updated the wiki page for file2 as the option - processStrategy -
was missing and this is the option you need.
http://cwiki.apache.org/confluence/display/CAMEL/File2
from("fp://someserver/inbox?username=foo&password=bar&processStrategy=#myReadyFileStrategy").to("bean:handleFile");
And then you can declare a bean in spring XML (if using this)
<bean id="myReadyFileStrategy" class="com.mycompany.MyReadyFileStrategy"/>
Notice the # syntax on the URI parameter. It tells Camel to go look
for it in the registry.
