Java.lang.IllegalStateException:Can't Obtain format

Question

Hi,
I am trying to run an image manipulation program on a Tomcat server. When the program deals with PNG images it is fine but everytime it trying to do anything with JPEG2000 images it throws the java.lang.IllegalStateException:Can't Obtain format error. I have placed all the relevent jars in the shared/lib folder of my Tomcat installation and so it shouldn't have any problem finding the format but it is. Can anyone help?

Answer 1

I wrote the program myself using javax.imageio.* and javax.media.jai.* libraries. It's just a program that converts from TIFF to JPEG2000. It works well when I run it locally but as soon as I deploy it on Tomcat it throws the error.
