Sorry for few details as this has been a several message question. I have created a Drools plugin that contains EITHER the maximum number of jars and dependencies (i.e. ALL), or the minimum (i.e. those needed for compiler option only processing DRL files), or adding the entire Drools distribution to my Java extensions folder in OS X, and in all instances, I get an error loading dialects. The enigma for me is that all of these plugin options enable me to make a stand alone RCP application that works fine.</div><div><br class="webkit-block-placeholder"></div><div>Here is the test unit code:</div><div><br class="webkit-block-placeholder"></div><div><div style="margin-top: 0px;
