er, no. esql is not dependent on java at all - there's a perl
implementation out there in axkit. it _is_ an xsp logicsheet though, which
means that esql page authors can rely on having a procedural programming
language available via the xsp:logic and xsp:expr tags. matt's point (with
which i wholeheartedly agree) is that flow control in xsp pages should
always be done using the procedural language.
