Subject Re: Problem configuring JDBC DataSource Tomcat 5.5.23 / MySQL 5.0
Date Thu, 08 Nov 2007 23:08:26 GMT
For the record I discovered the problem. Somehow there was a
context.xml file located in %TOMCAT_HOME%\conf\Catalina\localhost for
my web apps context which contained an empty <context> node. Once I
deleted that one and redeployed the correct context.xml was put in
there.  Not sure why the one from my webapps META-INF directory wasn't
replacing that one to begin with like it did after I deleted it.
