I'm trying to convert a simple XSP application from AxKit to
Cocoon, and ESQL isn't being interpreted.
In my original application, the uninterpreted XML shows up in my
output documents. To simplify my testing, I tried two things:
1) Running a simple example from the request taglib to make sure
taglibs in general were working. They were.
2) Running the sample ESQL from the Cocoon documentation, hoping
I would get some sort of error to indicate that the sample
database configuration wasn't present, but that the esql
taglib was being invoked. No such luck.
For the 2nd test, I used the following XSP page:
---
<xsp:page
language="java"
xmlns:xsp="http://apache.org/xsp";
xmlns:esql="http://apache.org/cocoon/SQL/v2";
>
<esql:connection>
<esql:pool>myConnection</esql:pool>
<esql:execute-query>
<esql:query>SELECT content FROM xml_document where id = 1</esql:query>
<esql:results>
<table>
<esql:row-results>
<tr>
<td><esql:get-string column="content"/></td>
</tr>
</esql:row-results>
</table>
</esql:results>
<esql:no-results>
<p>Sorry, no results!</p>
</esql:no-results>
</esql:execute-query>
</esql:connection>
</xsp:page>
---
The entire contents of the resulting "HTML" page:
---
<esql:connection
xmlns:xspdoc="http://apache.org/cocoon/XSPDoc/v1";
xmlns:esql="http://apache.org/cocoon/SQL/v2";
xmlns:xsp="http://apache.org/xsp";>
---
Note that my original application includes all the ESQL tags and
their contents; I don't know why I'm getting just the connection
tag from the sample app.
My pipeline from sitemap:
---
<map:pipeline>
<map:match pattern="db.html">
<map:generate src="newsletter/xsp/db.xsp" type="serverpages"/>
<map:serialize type="html"/>
</map:match>
</map:pipeline>
---
>From cocoon.xconf:
---
<builtin-logicsheet>
<parameter name="prefix" value="esql"/>
<parameter name="uri" value="http://apache.org/cocoon/SQL/v2"/>
<parameter name="href"
value="resource://org/apache/cocoon/components/language/markup/xsp/java/esql.xsl"/>
</builtin-logicsheet>
---
I'm using Postgres, and it's entirely possible that my JDBC
driver is not set up properly, but this doesn't strike me as a
database configuration problem if the esql tags are showing up in
the output.
Relevant software versions:
Java: 1.4.1 (beta, Blackdown release)
Tomcat: 4.1.18
Cocoon: 2.0.4
Many thanks for any assistance. I started working with Cocoon
this weekend, so it's entirely possible I am overlooking
something obvious.

Incidentally, while experimenting with the JDBC connectivity, I
noticed that the JDBC example in the Cocoon documentation refers
to a class that doesn't exist: org.apache.cocoon.Roles. Is this
a recent change that has not yet been documented?
On the topic of documentation, I also noticed that the API docs
don't link to the org.apache.avalon docs; that would seem to be a
particularly relevant API for cross-referencing.
