Question
Anyone know a way to remove these warnings? or solve the problem?

Have you read the actual error? And did you try to use google or one of its friends?
Oh, and read the PLEASE PLEASE PLEASE... topic in this forum, it's almost the first one/top one
Cheers,
Ronald

Have you found a solution for this? I have the same problem. I've read all topics about it on this forum:
viewtopic.php?f=3&t=20323
viewtopic.php?f=3&t=16639
viewtopic.php?f=3&t=16145
viewtopic.php?f=3&t=24403&start=10
viewtopic.php?f=3&t=15271
And still no solution.
The image shows up the first time, but if I refresh the page I get the same error you mentioned.

Hmmm, interesting. Shows up first time? This is similar to the fileDownload behavior/issue that has been discussed many times in this forum. I solved this issue/behavior in my JSF/PrimeFaces web app months ago; solution is to re-call the same code that populates the streamed content (on page refresh requests). See below.

I searched google for the following:
stackoverflow WARNING: JSF1091: No mime type could be found for the file dynamiccontent
Found the following:

I did this BEFORE my previous post/response above.
