The pool is defined for the connection, not the query. ie:
<xsp:page language="java" xmlns:xsp="http://apache.org/xsp"; xmlns:esql="http://apache.org/cocoon/SQL/v2";>
<records>
<esql:connection>
<esql:pool>directory-pool</esql:pool>
<esql:execute-query>
<esql:query>SELECT * FROM department</esql:query>
<esql:results>
<esql:row-results>
<record><esql:get-columns /></record>
</esql:row-results>
</esql:results>
<esql:update-results />
<esql:no-results />
<esql:error-results />
</esql:execute-query>
</esql:connection>
</records>

I am just starting out using cocoon and am trying to use esql database tags.
i have cocoon 2.0.4 running on tomcat 4.1.18 and postgresql 7.3.
i have configured the cocoonc.xconf with the following:
<jdbc name="directory-pool"> <pool-controller min="1" max="60" /> <dburl>jdbc:postgresql://localhost/directory</dburl> <user>user_id</user> <password>mypass</password> </jdbc>
and set-up the web.xml with:
<init-param> <param-name>load-class</param-name> <param-value> <!-- For IBM WebSphere: com.ibm.servlet.classloader.Handler -->
<!-- For Database Driver: --> org.hsqldb.jdbcDriver org.postgresql.Driver <!-- For parent ComponentManager sample: org.apache.cocoon.samples.parentcm.Configurator --> </param-value>
i have an xsp that should connect to the database and create an xml file:
<xsp:page language="java" xmlns:xsp="http://apache.org/xsp"; xmlns:esql="http://apache.org/cocoon/SQL/v2";>
<records> <esql:connection> <esql:execute-query> <esql:pool>directory-pool</esql:pool> <esql:query>SELECT * FROM department</esql:query> <esql:results> <esql:row-results> <record><esql:get-columns /></record> </esql:row-results> </esql:results> <esql:update-results /> <esql:no-results /> <esql:error-results /> </esql:execute-query> </esql:connection> </records> </xsp:page>
but when i try to get the xml document, i get the following error in the access.log
ERROR (2003-08-18) 11:34.19:920 [access] (/test/directory/directory.xml) Thread-8/CocoonServlet: Problem with Cocoon servlet
