Hi Gerrie,

most time I do see these kind of issues, the reason is class-loading related. 
From what you describe I'd have a look at your tomcat installation and make 
sure that there is no jar file clash:

Tomcat loads classes from different places before it locks up your deployed WAR 
file. Also you may try to purge any files left over from previous deployments, 
before giving it another try. (If you are deploying within an IDE eg. Eclipse, 
there are additional folders you have to be aware of, where file might be left 
over from previous deployments.)

Hope that helps.

Cheers Andi.
