Hello Guys,

   I write some codes to render a pdf file into a view page. For some pfd file, they works fine, while others files got different errors. The errors are like:

    Invalid char `\XXX' in expression, OR     unexpexted tCONSTANT / tIDENTIFIER, expecting 'XX' ...

    Do you guys have any idea how to get ride of these errors?

    --> Here is my action:

def show_pdf     respond_to do |format|       format.pdf do         render :file =>params[:pdfName]+'.pdf', :layout => false      end    end   end

    --> Errors in Log file:
