Hi,
I am trying to query a mysql database from my cocoon installation. I am
using Cocoon as a webapp of tomcat.
I made the next changes:
I added mysql Driver to web.xml:
<init-param>
<param-name>load-class</param-name>
<param-value>
<!-- For parent ComponentManager sample:
org.apache.cocoon.samples.parentcm.Configurator -->
<!-- For IBM WebSphere:
com.ibm.servlet.classloader.Handler -->
<!-- For Database Driver: -->
<!--org.hsqldb.jdbcDriver-->
<!-- Example for a MySQL database driver -->
com.mysql.jdbc.Driver
<!--org.gjt.mm.mysql.Driver-->
</param-value>
</init-param>
I added an entry to cocoon.xconf:
<jdbc name="mmis2">
<pool-controller max="10" min="5"/>
<auto-commit>true</auto-commit>
<dburl>jdbc:mysql://localhost/mmis2</dburl>
<user>user</user>
<password>user123</password>
</jdbc>
and a match pipeline to sitemap.xmap:
<map:match pattern="index.html">
<map:generate src="style/queries/query.xml"/>
<map:transform type="sql">
<map:parameter name="use-connection" value="mmis2"/>
</map:transform>
<map:serialize type="xml"/>
</map:match>
query.xml is:
<?xml version="1.0"?>
<results xmlns:sql="http://apache.org/cocoon/SQL/2.0";>
<sql:execute-query xmlns:sql="http://apache.org/cocoon/SQL/2.0";>
<sql:query>
select * from collections
</sql:query>
</sql:execute-query>
</results>
I copied the mysql connector (mysql-connector-java-3.0.16-ga-bin.jar) to
cocoon/WEB-INF/lib
I thought everything was well configured but i get always:
"Failed to obtain connection. Made 5 attempts with 5000ms interval"
Any clue, why i am still getting this error?
thanks in advanced for your future feedback and merry christmas!!
