I know the standard JSP language doesn't allow for it. I don't know about JSF EL. I'd prefer not to have to learn yet another language (nor try to explain it to the other developers). Clearly, someone came up with the example on that page in the first place, so I'm hoping whoever wrote that might chime in with an explanation of how he got it to work. eric -- View this message in context: http://www.nabble.com/Using-JSP-EL-expression-language-in-camel-tp25228176p25228941.html Sent from the Camel - Users mailing list archive at Nabble.com.
