I had met your issue,then I had to reset the jetty's properties file,then it can run well.
<bean id="securityConstraint" class="org.eclipse.jetty.util.security.Constraint"> <property name="name" value="BASIC" /> <property name="roles" value="user,admin" /> <property name="authenticate" value="false" /> *update this tag to false* </bean> NOTE: I think you didn't set the security is right,so you need to define user and password of jetty. -- View this message in context: http://activemq.2283324.n4.nabble.com/REST-API-client-ecountering-Status-401-Unauthorized-tp4666184p4694678.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
