Subject strange database problem
Date Sun, 30 Jun 2002 17:24:06 GMT
Hello,
I had to connect cocoon to msde engine (do not ask why .. it will be ms sql
server in the final distribution) .. while searching for jdbc driver i have
found jadozoom from http://www.infozoom.de/NS/javaado.html

I've bin using win32 tomcat 4.0.1 with cocoon 2.1-dev (some weeks old dev
snapshot - I think it was xml-cocoon2_20020421102223.tar.gz but I'm not sure).
It's been working more than fine. After installing cocoon
xml-cocoon2_20020625041850.tar.gz snapshot strange error occured (I've put the
full stacktrace at the end of the message):

WARN    (2002-06-30) 18:58.08:045   [sitemap] (/cocoon/xspxml/cdn)
HttpProcessor[80][4]/PipelineNode: Error while processing pipeline at
jndi:/localhost/cocoon/sitemap.xmap:645:17
org.apache.cocoon.ProcessingException: Exception in
ServerPagesGenerator.generate(): java.lang.RuntimeException: Error executing
statement: select * from cdn.towary: com.inzoom.adojni.ComException: Current
provider does not support returning multiple recordsets from a single
execution. in ADODB.Recordset code=0 Type=1

First I thought that it's something wrong with msde provider or jdbc driver
but getting back to 2002.04.21 dev snapshot makes the error disappear.

I switched to Inet Opta driver but it does not show polish letters correctly
.. 

I'm really stuck. Could anyone tell me if this is a cocoon bug or maybe a
cause of some functionality extension that will last from now on ? 


The stacktrace is:
