Found the problem. When I hit Ctrl-Shift-F in Eclipse to format my XML in my
xbean.xml file, the following whitespace was introduced and drools didn't
interpret my namespace context correctly. So much for trying to keep my XML
pretty. >-(
From:
<drools:namespace-context id="nxContext">
<drools:namespaces>
<drools:namespace prefix="my">urn:my:ns</drools:namespace>
</drools:namespaces>
</drools:namespace-context>
To:
<drools:namespace-context id="nxContext">
<drools:namespaces>
<drools:namespace prefix="my">
urn:my:ns
</drools:namespace>
</drools:namespaces>
</drools:namespace-context>
