Hi Richard.

I use the servlet supplied with FOP (in 
<fopdir>/examples/servlet/build/fop.war) and it works fine.
I'm afraid my Java familiarity is very basic - so can't comment on your 

I use Apache 1.3.27 and Tomcat 5.0.28 and jdk_1_5_0_2

If you are processing an FO file that works fine under FOP 0.20.5 are

(as your example has no attributes on any other table-cells - and the 
produced PDF is what you would get if the 'spanned' attributes were not
