Deepak Panda:

Hi,Whenever I am trying to view thumbnail of PDF, after upload it in document and media, it shows below error for each PDF in log. kindly provide the resolution for resolve this issue.

For us to come up with a solution, please start with

information about the exact version of Liferay that you're asking about
the full unabbreviated error message
(if there's a stacktrace: Include it)
Does this happen for any pdf? (try to upload trivial ones, from different sources)
Do you have any specific configuration in your system, e.g. imagemagick (which can be used for preview generation)
