I was going to suggest you raise a bug report in JIRA, but I found there
already was one
(http://opensource.atlassian.com/projects/xdoclet/secure/ViewIssue.jspa?key=XDT-349)
There's a good explanation in there of why the namespace isn't found,
and a workaround that involves subclassing the doclettask to register
the tag handler.
An alternative workaround in your case might be to use Ant's uptodate
task to skip the ejbdoclet call completely if nothing's changed.
