[rules-users] Getting a NamespaceException when building the rule package

[aldrinbondoc]

Hi All,

We are trying to build the rule package in Guvnor via HTTP request, since
compilation is not readily available via RestAPI, we developed a custom web
service that will handle our request and trigger invoke a drools api that
would compile the rule package. 

The problem is when we tried to invoke the compilation via HTTP request we
are encountering this exception:

org.drools.repository.RulesRepositoryException:
javax.jcr.NamespaceException: drools: is not a registered namespace prefix.

Here is what we saw from the log file.

Has anyone encountered the same exception before? Your response would be
very much appreciated. Thanks!

BTW. We have BRMS 5.0 hosted on Jboss EAP 4.3.0 application server.
