expressions within HTTP uri not being resolved

ndouglas60 Jun 13, 2012 5:39 PM

I am trying to call a rest service with the following:

<to uri="http://localhost/api/save?param1=$&param2=$" /> but the $ and $ expressions are not being resolved as I would expect and can see when I send them to the log.

Any suggestions?

Thanks,

Nate D.

I just did some test on the trunk, you should define the route like this, to let the property value to be used.

<to uri="http://localhost/api/save?param1={{param1}}&param2={{param2}}" />

Willem,

Thanks for your response, but I didn't explain my situation fully. The parameters are values that I created within the route as headers, so they should read header.param1 and header.param2. This is why I was using ${} to resolve the expression.

Essentially I need to pass header values to the uri.

Thanks,

Oh, you have to set the HTTP URI with the message header this time.
As the expression doesn't work per Endpoint, it only works per Exchange.

Are you using Spring XML and its property placeholders? If so read this FAQ
