Subject Re: Date String Creation
Date Thu, 08 Dec 2011 05:55:50 GMT
For example, lets say I had a value in a route that I could get with some
simple xpath, but I needed to pass that as a parameter to a bean that would
do some calculation on that value and return it, so that I could then set it
as a header or such.  Is there a way this could be done without relying on a
custom processor?

For instance, I know I can do the following to get a value from a bean
method:
<setHeader headerName="lastRunDate">									
	 <method ref="lastRun" method="getLastRunDate"/>
</setHeader>

But what if I want to have a bean that will take in a value thatis not the
entire message body and do something with it?  Such as a value resolved from
this expression:
<xpath resultType="java.lang.String">//s:randomInfo</xpath>


How can that be best accomplished?  I know a custom processor allows you
full access to the headers and body, as would a bean with annotations of the
headers and body, but it seems like overkill if all I would want to do is
set and retrieve a value from a bean such as a singleton to be utilized by
the route.
