[udig-devel] tif render error.

[Vince Darley]

We've continued to dig a bit deeper into this, and it's clearly 
caused by our own product build and product runtime 
configuration.  If I take the standalone build of udig rc14, I can 
load our tiff images into it.  I can also replace the jre in it with 
the one we use (based on java 1.6) and it still works just fine.

But, our product whether built and exported from eclipse or run from 
within eclipse just can't find the JAI stuff.  Any pointers to how 
this should be configured?

regards,

Vince.
