Grails: Cannot create JDBC driver of class ‘com.mysql.jdbc.Driver’ for connect URL ‘jdbc:hsqldb:mem:grailsDB’

January 20, 2012 by Annyce Davis Leave a Comment

Recently received the following error when attempting to deploy a new war file on my Glassfish server:

Cannot create JDBC driver of class ‘com.mysql.jdbc.Driver’ for connect URL ‘jdbc:hsqldb:mem:grailsDB’

The solution to the issue however, has nothing to do with MySQL and drivers whatsoever.  The problem was that I mistyped the environment name when creating the war file.

I typed grails rstaging war instead of grails staging war.  This is just another example of extremely useful error messages that I’ve encountered while developing for Grails.

Adding HTTP Access Logging to Glassfish 3.0 Server

November 13, 2010 by Annyce Davis Leave a Comment

Recently I had the need to monitor the requests that were being sent to my Glassfish server. Here is the simple configuration change that needed to be done to the domain.xml file:

<configs>
  <config name="server-config">
 <http-service enabled="true"></http-service>
  <access-log format="%client.name% %auth-user-name% %datetime% %request% %status% %response.length% %header.referer%"></access-log>
  <virtual-server id="server" log="/mnt/httpd/logs/access" listeners="http-listener-1"></virtual-server>
  <virtual-server id="__asadmin" listeners="admin-listener"></virtual-server>
 ....
 </config>
 </configs>
