[rules-users] Re: Re: JBRMS Query, very imp for me

Wed May 30 14:35:13 EDT 2007

Unfortunately I'm unable to reproduce this error with the latest  
stable build, http://cruisecontrol.jboss.com/cc/artifacts/jboss-rules/ 
drools-4.0.0.SNAPSHOT-brms.zip

I was getting a similar error a couple of weeks ago duo web.xml  
descriptor problems.

Please check your web.xml for the following servlet mapping.

<servlet-mapping>
		<servlet-name>PackageDeploymentServlet</servlet-name>
		<url-pattern>/org.drools.brms.JBRMS/package/*</url-pattern>
</servlet-mapping>

or download the last snapshot.
