<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">I am having problems with testing Drools rules; the code is JUnit setup code that is shown below. However, I get a problem that the dialect cannot be opened (see after code). This problem persists whether I tell JUnit to use my core plugin, or if I add every piece of code in the Drools distribution. I added the several lines about Java configuration, and this has made no difference. The crash occurs on the first line invoking Drools routines. I know I am having so much trouble with this code that many readers are tiring of my stupidity, but I just don't get this. The core plugin that I am including in the classpath runs completely well in the standalone RCP. Thanks for any assistance.<div><br class="webkit-block-placeholder"></div><div>- Mike<br><div><br class="webkit-block-placeholder"></div><div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px;
