Not really. It's clearly a POI exception and I'd have no idea where to start debugging that.

Compare directory listings, compare jar file sizes & names, compare config files. p > Java version is 1.5.0_18-b02 > Windows version is Windows Server 2003 SP2 > Tomcat version: 5.5.20 > > Libraries: > *http://bit.ly/casaPs* > Shared only has cewcanative.jar > > Any idea of what's causing the problem? > > Thanks in advance. >
