Re: question

Are you sure you are running under 1.4? It really looks like you are
runing a jdbc1 (i.e. jdk 1.1) version of the sun core java.sql library
(the method java.sql.Statement.getResultSetConcurrency() was added in
jdk1.2 (i.e. jdbc2)). If you are running 1.4, are you sure you don't
have a jdk1.1 set of jars in your classpath that are getting picked up
before the 1.4 ones?
