I changed the namespace suffix:
<?xml version="1.0" encoding="UTF-8"?>
<jboss:webservices>
<context-root>/TestProjectEE</context-root>
</jboss:webservices>
You need to define namespace. See below:
<webservices
xmlns="http://www.jboss.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
version="1.0"
xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee http://www.jboss.org/j2ee/schema/jboss_webservices_1_0.xsd">
<context-root>/TestProjectEE</context-root>
</webservices>
