javax.jms does not exist - compiling activemq examples

I'm trying to compile the examples that come with activemq

in apache-activemq-5.1.0\example\src\

TopicPublisher.java, CommandLineSupport.java

on compiling thru netbeans it has some referencing problems saying javax.jms does not exist.

I've tried the j2ee.jar, openjms, sun jms but they all give the same error.

its also complaining about org.apache.activemq.util does not exist but I'm referencing activemq-all-5.1.0.jar.

note: all other references to external jars are working fine

any ideas?

Edit: the jars needed to be referenced are

activemq-core-5.1.0.jar
geronimo-jms_1.1_spec-1.1.1.jar
commons-logging-1.1.jar
geronimo-j2ee-management_1.0_spec-1.0.jar

they're in the activemq binary dist in the lib folder
