Subject Re: [c2] q: howto use ESQL inside own logicsheets?
Date Tue, 04 Dec 2001 17:20:52 GMT

Obviously the ESQL logicsheet is not being applied.  In Cocoon 1 this would
imply that you had removed the declaration of the esql logicsheet from
cocoon.properties, or that your namespace declaration URI didn't match the
one in the logicsheet.  I don't know how this works in Cocoon 2; maybe the
sitemap?  I know some of the namespace URI's have changed; is it possible
that the one for ESQL is something other than "
http://apache.org/cocoon/SQL/v2"?

If either of these is true then you shouldn't be able to even get a simple
XSP using ESQL to work.

If you *can* get ESQL to work using simple XSP, then it suggests that you
are somehow managing to strip out the ESQL namespace declaration with your
logicsheet.  If that is also not true, perhaps you have found a bug, and
should report it to cocoon-dev.

Sorry I can't help more - I haven't yet upgraded to C2.
