RE: Problem connecting to MySQL - Solved
Problem now solved - it appears that the DB connection parameters needed to be defined in the sitemap, not in the input XML. The answer came from documentation on the SQL Transformer on the Apache Cocoon site - http://cocoon.apache.org/2.1/userdocs/transformers/sql-transformer.html So the sitemap and XML input now read: ***Sitemap.xmap** map:pipeline map:match pattern=sqltest map:generate src=sqlextract.xml/ map:transform type=sql map:parameter name=use-connection value=ward_connect/ map:parameter name=show-nr-of-rows value=true/ map:parameter name=clob-encoding value=UTF-8/ /map:transform map:serialize type=xml/ /map:match /map:pipeline *sqlextract.xml*** page content execute-query xmlns=http://apache.org/cocoon/SQL/2.0; query name=Ward Names select admin_name from wards/query /execute-query /content /page Whereas before they read: **INCORRECT sitemap.xmap*** map:pipeline map:match pattern=sqlconnect map:generate src=sqlextract.xml/ map:transform type=sql map:parameter name=use-connection value=ward_connect/ /map:transform map:serialize type=xml/ /map:match /map:pipeline **INCORRECT sqlextract.xml*** document sql:execute-query xmlns:sql=http://apache.org/cocoon/sql/2.0; sql:use-connectionward_connect/sql:use-connection sql:query select admin_name from wards; /sql:query /sql:execute-query /document Thanks to Tony for your suggestions :) Guy ** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

RE: Problem connecting to MySQL
Hi Tony, Thanks for going through the details and confirming that it is OK. I did restart Tomcat after copying the mysql.jar to the tomcat lib directory. I wondered if the SQL Transformer had 'broken' or I had a bad install, so I reinstalled all the components yesterday, but to no effect. I tried your suggestion, declaring the SQL namespace at the root tag, but again to no effect - this is the output: ?xml version=1.0 encoding=ISO-8859-1 ? - document xmlns:sql=http://apache.org/cocoon/sql/2.0; - sql:execute-query sql:use-connectionward_connect/sql:use-connection sql:queryselect admin_name from wards/sql:query /sql:execute-query /document - which is also the input ;) I forgot to mention that I am working on win 2K - if that makes any difference. If this isn't a problem with cocoon, then could it be with the MySQL database? It is installed on Localhost:3306, but apart from start the MySQL server running, I don't do anything else. I assume that from the connection parameters in cocoon.xconf.. datasources jdbc name=ward_connect pool-controller min=5 max=10/ dburljdbc:mysql://localhost:3306/ward_data?autoReconnect=true/dburl useradministrator/user passwordmypassword/password /jdbc /datasources .cocoon can find the database and connect to it? Although I read an instruction on http://www.candlelightsoftware.com/orion-cocoon.html way down the page under the bullet point Initialize the database using mysql that appears to call mysql from inside cocoon? is it a requirement for MySQL to physically sit inside Tomcat/Cocoon on the directory? I thought that the mysql.jar would find and connect to MySql wherever it is, as long as the connection parameters are OK. I have played around with the access settings to the mysql database (setting access from all locations, from localhost only etc..), but again - no change. In any case, If there was a problem connecting to the database then surely cocoon would throw up a error message to that effect, but according to the access log, there are no problems! So i am still stumped, but have to get this sorted soon! deadlines are approaching fast! gulp If you think of anything else. I will be very grateful for your help, thanks, Guy ** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

Problem connecting to MySQL
Dear Listers, I am a newbie with Apache Cocoon and am trying my hand connecting to a MySQL database, with some difficulty. I have researched alot and still cannot find the answer to this problem. First the background info: Cocoon 2.1.5 Tomcat 5.0.27 mysql-3.23.38 j2sdk1.4.2_04 mysql-connector-java-3.0.11-stable-bin.jar I have adjusted the following files to setup a database connection to MySQL: ***cocoon.xconf** datasources jdbc name=ward_connect pool-controller min=5 max=10/ dburljdbc:mysql://localhost:3306/ward_data?autoReconnect=true/dburl usermyusername/user passwordmypassword/password /jdbc /datasources web.xml init-param param-nameload-class/param-name param-value !--For SQL Database Driver-- com.mysql.jdbc.Driver /param-value /init-param *sitemap.xmap map:pipelines map:pipeline map:match pattern=sqlconnect map:generate src=sqlextract.xml/ map:transform type=sql map:parameter name=use-connection value=ward_connect/ /map:transform map:serialize type=xml/ /map:match /map:pipeline /map:pipelines ..and am using this xml file to describe the SQL query and also to describe the connection parameters again: **sqlextract.xml*** ?xml version=1.0 encoding=UTF-8? document sql:execute-query xmlns:sql=http://apache.org/cocoon/sql/2.0; sql:use-connectionward_connect/sql:use-connection sql:query select admin_name from wards; /sql:query /sql:execute-query /document I have copied the mysql-connector-java-3.0.11-stable-bin.jar file to the C:\jakarta-tomcat-5.0.27\common\lib and set up the JAVA SDK as per instructions BUT when I try and view http://localhost:8080/cocoon-test/sqlconnect in my browser, all I get is an xml replication of the sqlextract.xml document and when I check the Access Log file, there is a message as per the following: ** INFO(2004-06-18) 18:14.38:062 [access] (Unknown-URI) Unknown-thread/CocoonServlet: Reloading from: jndi:/localhost/cocoon-test/WEB-INF/cocoon.xconf INFO(2004-06-18) 18:15.45:500 [access] (/cocoon-test/sqlconnect) http-8080-Processor25/CocoonServlet: 'sqlconnect' Processed by Apache Cocoon 2.1.5 in 1.969 seconds. ** The output is not what I was expecting, which should be a list of names - is there a problem with the way I have set up the database connection? Do I need to add a different serializer to view the output? I was under the impression that the XML serializer would deliver the raw SQL data to the browser. The SQL Query select admin_name from wards works from the MySQL prompt. Any help will be greatly appreciated as I have no idea why this is happening. cheers, Guy ** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

It appears the SQLTransformer is not SQLTransforming :) You said you copied the mysql jar into the tomcat lib directory... did you restart Tomcat after this?

The SQL Query select admin_name from wards works from the MySQL prompt. Any help will be greatly appreciated as I have no idea why this is happening. Hmm, if the SQLTransformer is not transforming, I would think that it has something to do with your namespaces in the source document. What if you try declaring the SQL namespace at the root tag: document xmlns:sql=xmlns:sql=http://apache.org/cocoon/sql/2.0; and then just use: sql:execute-query sql:use-connectionward_connect/sql:use-connection sql:queryselect admin_name from wards;/sql:query /sql:execute-query Regards, Tony - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Ignore the literal text, and just try declaring the sql namespace in the root document tag, and see if it works.
