Read_image_file command does works on Linux application server

Question

Hello!
I have a form with a new_form_instance Trigger I wrote the read_image_file trigger to read a GIF file in an image item.It works fine on windows XP(development machine).I copied the GIF file to the same location where my fmx files are there in Linux application server.I copied and compilied my fmb file in linux application server.No compilation error is there.But when I run form from Linux the form hangs and my read_image_file command is at new form instance Trigger.I have checked the case sensitivity of the file and the permission etc in Linux.In windows Development machine the form runs successfully.What could be the problem.Please help.......

For me, attempting the following:
  READ_IMAGE_FILE('bullet_ball_glass_blue.gif', 'GIF', 'IMAGE7');
gives this error:
  FRM-47109: Cannot locate image file bullet_ball_glass_blue.gif
Changing my command to:
  READ_IMAGE_FILE('bullet_ball_glass_blue.gif', 'URL', 'IMAGE7');
loads the image successfully.
If you truly are not getting an error message (mine appears in the status bar), then perhaps the file is being found, but the image format is not recognized or otherwise incompatible. Test this by loading one of the the images that load successfully into your iconic buttons. If that image loads successfully into your image item, fix the problem GIF image. (Recreate or open & resave with a graphics program, etc.)
If this does not appear to be the problem, the only things I can think of are for you to confirm that, in formsweb.cfg:
  1. The archive_jini entry includes your image JAR
  2. If imageBase=DocumentBase, change to imageBase=codebase
The second change may temporarily break your iconic buttons. This can be fixed by updating the buttons' Iconic Filename properties specifying only relative paths found within the JAR. Since my image is stored in the root of my JAR, no path need be specified. Had I placed my image in a subdirectory within my JAR, named images, my call would have to be changed to the following:
  READ_IMAGE_FILE('images/bullet_ball_glass_blue.gif', 'URL', 'IMAGE7');
I'm not sure whether any of these suggestions will help, but since I had no problems, I suspect it's simply a matter of differing configurations. The two items that I listed are the only two likely differences I could think of.
