You didn't mention your platform, and so a missing native library could have been the problem (not sure how much of JAI is native these days). Since it works outside of Tomcat, you're probably okay. I agree with Pid and Thad: try not to install anything extra into the system classpath by putting libraries like JAI into JRE_HOME/anything. It's best to bundle them with your webapp and/or use "-classpath" when launching non-webapp code. Finally, I'd just like to mention that uses of JAI (or really any Java image I/O) tends to reach the limits of scalability rather quickly unless you are careful about things like image size and numbers of simultaneous operations on images. Consider the fact that images are rather large and can consume a lot of memory, especially with many potential simultaneous users. If you are doing operations that don't actually require that you actually decode the entire image (such as determining image metadata, etc.) consider avoiding a full-image operation. Also consider a batch-processing model where your webapp records the desired operations and another process comes along and actually performs those operations. That can often give the user a better experience and also give you a more stable system.
