Single JDBC connection for EJB CMP?

Am I right in thinking that an EJB JAR using CMP can only use a single JDBC
connection? (In my case I'm using JBoss 3.x)

No. CMP is not required to use JDBC for persistence at all. If it
does, then the spec has nothing to say about how many connections will
be used either serially or simultaneously. It must be possible to
configure at least some of these things in the app-server-specific
deployment file, but you should certainly not assume that only one
connection will be used unless you find a documented way of configuring
things that way.
