ICEFaces 'Content is not allowed in prolog' Error

Question

Hello,

I have an JSF/ICEFaces application that is works fine but I keep getting this error. Although the application continues normally, I still get that error now and then. As far as I understand it's complaining about having something in the file before XML header but I'm not sure why I'm getting this I'm using ICEfaces that generates XML back and forth for AJAX.

Any ideas?

Thanks,

Tam

Answer 1

Could you paste the top of the troublesome line. It might just be extra linefeeds or an erroneous character outside a tag.

Answer 2

This typically occurs if a jspx is not a valid XML file. There should be one root f:view element, and namespace imports should be placed under it.

Check out this file for an example structure of jspx file.
