I'm running
* Tomcat 5.0.18 running as a Wndows service,
* MySQL 4.0.16 running as a Windows service, and
* MySQL Connector/J 3.0.10 stable
all on Windows 2000 Server, which is where I'm also doing the testing (i.e., on localhost).
A number of tomcat-user mailing list denizens have given me snippets of XML to put in various places. Nothing worked. So I tried following the "MySQL Configuration" example from http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html. After all changes were made to server.xml, web.xml and timesheet.xml (the <context> fragment under conf/Catalina/localhost), I restarted Tomcat and tried to login (the first action that would have had to touch the MySQL database).
I got the following errorPage:
> At Timesheet.Util.errorPage(Util.java:550) there occurred a
>
java.lang.Exception: A fatal exception occurred while retrieving login name and pass phrase because...
>
> At Timesheet.Util.getSqlConnection(Util.java:492) there occurred a

OK, that seems to say it doesn't know what the name "jdbc/TimesheetsDB" is. Tomcat has written nothing to stderr.log and stdout.log shows a clean startup, so Tomcat itself isn't too perturbed. stdout.log includes the following line:
> INFO: Processing Context configuration file URL file:C:\Program Files\Apache Group\Tomcat 5.0.18\conf\Catalina\localhost\timesheet.xml
implying that my timesheet.xml context fragment file was found and processed. The Timesheet application log file contains the following:
> 2004-02-10 16:20:05 NamingContextListener[/Catalina/localhost/timesheet]: Resource parameters for jdbc/TimesheetsDB = ResourceParams[name=jdbc/TimesheetsDB, parameters={factory=

org.gjt.mm.mysql.Driver, username=timesheet_app, maxIdle=30}]

> 2004-02-10 16:20:05 NamingContextListener[/Catalina/localhost/timesheet]: Resource parameters for UserTransaction = null
[Blank lines added for clarity.] As per the instructions in the jndi-datasource-examples-howto.html page, my web.xml file has the following addition
> <resource-ref>
> <description>MySql Connection Pool</description>
> <res-ref-name>jdbc/TimesheetsDB</res-ref-name>
> <res-type>
javax.sql.DataSource</res-type>
> <res-auth>Container</res-auth>
> </resource-ref>
immediately after the <error-page> element and immediately before the <security-constraint> element.
Now that I am using the timesheet.xml <context> fragment file, server.xml is unchanged except that I have modified it to use port 80 in place of 8080 and port 443 in place of 8443.
The timesheet.xml <context> fragment file looks like this:
<Context path="/timesheet" docBase="timesheet" debug="9" reloadable="true"
crossContext="true" displayName="ConnectTel Timesheet Application">
<Logger className="
org.apache.catalina.logger.FileLogger"
prefix="localhost_timesheet_log." suffix=".txt" timestamp="true"/>
<Resource name="jdbc/TimesheetsDB" auth="Container" type="
javax.sql.DataSource"/>
<ResourceParams name="jdbc/TimesheetsDB">
<parameter>
<name>factory</name>
<value>
org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>maxActive</name> <!-- max db connections in the pool -->
<value>100</value> <!-- 0 implies no limit -->
</parameter>

</parameter>
<parameter>

</parameter>

<parameter>
<name>driverClassName</name> <!-- Class name for mm.mysql JDBC driver -->
<value>
org.gjt.mm.mysql.Driver</value>
</parameter>
</ResourceParams>
</Context>
I apologize for being so verbose, but I'm trying to provide all of the relevant information in the initial message. Does anyone see what I've missed? The example in jndi-datasource-examples-howto.html does NOT look like the other things I was told to do. (?)
