If I get ColdFusion MX, will I be able to use all of the features in JRun?
ColdFusion MX Standard 6.1 does not provide direct access to the J2EE APIs. Users that need access to the full range of capabilities in the J2EE platform should purchase ColdFusion MX Enterprise 6.1 which comes with a full license of JRun 4. Note: Access to the full set of J2EE APIs is only available when ColdFusion MX Enterprise 6.1 is installed in the J2EE configuration.
