All,<br><br>I am in the process of migrating my 3.0. project to the 4.x series and when I attempt to run my code I get the following exception when I attempt to load my .drl files:<br><br>Caused by: org.drools.RuntimeDroolsException
: Unable to load dialect &#39;org.drools.rule.builder.dialect.java.JavaDialect:java&#39;<br><br>Here is my package builder code:<br><br>static<br>&nbsp;&nbsp;&nbsp; {<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; try<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; {<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; builder = new PackageBuilder();
<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; builder.addPackageFromDrl( new InputStreamReader( RtvDecisionEngine.class.getResourceAsStream(&quot;rtv.drl&quot; ) ) );<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; builder.addPackageFromDrl( new InputStreamReader( RtvDecisionEngine.class.getResourceAsStream
