Referencing Database from Context.xml

Question

In the Context.xml file, I have reference to the database I am using for the application. Here is the Context.xml code.
<?xml version="1.0" encoding="UTF-8"?>
<Context path="ABATE" reloadable="true" docBase="C:\Documents and Settings\koconnor\EclipseWorkspace\ABATE" workDir="C:\Documents and Settings\koconnor\EclipseWorkspace\ABATE\work" >
     <Resource name="jdbc/ABATE" auth="Container" scope="Shareable" type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000"
        username="ccn" password="ccn" driverClassName="com.mysql.jdbc.Driver"
        url="jdbc:mysql://localhost:3306/abate?autoReconnect=true"/>     
</Context>Basically; what I need to know is how I can reference the value stored in "url" within a java class.

Answer 1

The point is that you DON'T access the URL directly. You just look up the datasource by name: jdbc/ABATE, and ask it for a connection. It will use the url to give you a database connection.
It abstracts the connection details from your code.
