Subject Re: jdbc and tomcat

the SQL error message does not look like if the driver itself could not 
be found, it appears more obvious to me, that the connection URL for the 
database is incorrect. Please check your database connection string, 
maybe the bug hides in there....:-)

To your xml problem: Did you also check, that all tags are correctly set 
with an start-<tag> and end-</tag>?
And remember that stand-alone tags always have to be closed with a final 
/ e.g. <stand-alone-tag/>...
