Subject [C1] Cocoon SQL vs ESQL: not working?!
Date Mon, 05 Nov 2001 14:09:27 GMT
More clarification:

All the code works OK as is on my test machine (localhost on an NT box), but the ESQL part
does NOT work on a UNIX machine.

The ESQL that is not working, simply ignores the ESQL tags and returns the text between them
(eg. 'org.gjt.mm.mysql.Driver') as though they were XML tags.

So - I do not think its an XSL issue per se.  I have set the path to the ESQL library in the
cocoon.properties file AND checked that the file is physically present.

Currently out of other ideas and quite frustrated!

Any help appreciated...

You don't say in what way the code is not working; do you get an exception,
other error message, or just no data? If the latter, are you sure your XSL
stylesheet matches the structure of the XML you are creating?

Subject:  [C1] Cocoon SQL vs ESQL


I have been struggling to get ESQL working... I had thought it was the
database setup, but turns out that is OK (see below) - now I am stuck
again.

Following previous suggestions, I have tried to get an equivalent of the
sample code shippped wiht Cocoon working.  I could not find any ESQL to
test, so I used the the SQL code instead - it worked!  But the - as far as
I can see - equivalent code in ESQL does not work.

I hope someone with a sharp pair of eyes can see why the first sample would
work, and the next one not??

Thanks!
Derek
