Btw we talked some time ago about letting the method call expression accept a list of expressions in the XML DSL, so each expression maps to the given parameter index. That way you can embed an xpath expression to map the parameter at that index. And for other parameters you can use <simple> <constant> etc. > -- > View this message in context: > http://camel.465427.n5.nabble.com/Date-String-Creation-tp5052753p5057766.html > Sent from the Camel - Users mailing list archive at Nabble.com. -- Claus Ibsen ----------------- FuseSource Email: cib...@fusesource.com Web: http://fusesource.com Twitter: davsclaus, fusenews Blog: http://davsclaus.blogspot.com/ Author of Camel in Action: http://www.manning.com/ibsen/
