I try to set the default datastore via jbosscmp-jdbc.xml
(see the file below):

When deploying, I get this error:

org.xml.sax.SAXParseException: Element "defaults" requires additional elements.

What am I doing wrong?

I am using jboss3.0.7

jbosscmp-jdbc.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jbosscmp-jdbc PUBLIC "-//JBoss//DTD JBOSSCMP-JDBC 3.0//EN" "http://www.jboss.org/j2ee/dtd/jbosscmp-jdbc_3_0.dtd">
