Thanks Claus, I was trying to keep out the Camel annotations. I wanted to have all the config/routes in Spring. My example route is:
> <route> > > <from>"ftp://rider.com/orders?username=rider&password=secret";</from> > <filter> > <simple>${bean:xmlFilter?method=match}</simple> > <to uri="log:worked"/> > </filter> > </route> How can I use XPath to pass the user to xmlFilter.match() in the below? <simple>${bean:xmlFilter?method=match}</simple> Thanks -----Original Message----- From: Claus Ibsen [mailto:[email protected]] Sent: Wednesday, February 01, 2012 9:26 AM To: [email protected] Subject: Re: Passing parameter values to bean methods via spring Hi You can use the Camel @Xpath annotation on a 2nd parameter in that method signature public boolean match(String username, @XPath("/Example/User") String user) { You may have to fiddle a bit to get the xpath expression working. Also sometimes you may have to use /text() to tell it to return the text content of the xml node. On Wed, Feb 1, 2012 at 3:05 PM, Gershaw, Geoffrey <[email protected]> wrote: > Thanks for the reply.
