java - Barbecue barcode generator does not show barcode number with a web app -


i tried barbecue barcode generator in stand alone java application , able print barcodes barcode number displayed in image.

enter image description here

but when execute same method spring web application, generated barcodes not show barcode number in below image. using same file path save images , have full rw permissions directory. have clue on this,

enter image description here

i using below code snippet

barcode = barcodefactory.createcode128a(barcode_id); file f = new file("/opt/rd/barcode/"+barcode_id+".png"); barcodeimagehandler.savepng(barcode, f);

i've fixed issue in grails setting font barcode , overwriting calculatesize() method in barcode:

private dimension calculatesize(){     dimension d = new dimension();     if(environmentfactory.getenvironment() instanceof headlessenvironment)     try     {          if(font == null)         {             d = draw(new sizingoutput(font, getforeground(), getbackground()), 0, 0, barwidth, barheight);         } else         {             java.awt.fontmetrics fontmetrics = getfontmetrics(font);             d = draw(new sizingoutput(font, fontmetrics, getforeground(), getbackground()), 0, 0, barwidth, barheight);         }     }     catch(outputexception e)     {         e.printstacktrace();     }     else     try     {         java.awt.fontmetrics fontmetrics = null;         if(font != null)         fontmetrics = getfontmetrics(font);         d = draw(new sizingoutput(font, fontmetrics, getforeground(), getbackground()), 0, 0, barwidth, barheight);     }     catch(outputexception e) { }     return d; }

this thread in sourceforge can shed more light on issue.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
