<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">I have an RCP application that uses Jess and have added code to switch to JBoss. I can create a sample rules project in Eclipse, but when I simply move the rules and the Java source from the JBoss rules project into my RCP, I get extensive errors. I have added the JBoss builder and the JBoss dependencies to the build path. I get extensive errors when I merely try to open, edit, or save the drl file, but I tried to run the code anyway. I guess basic question is how to add JBoss rules to an existing RCP project.<DIV><BR class="khtml-block-placeholder"></DIV><DIV>When the code is executed, it obviously opens the rules because the errors that I get indicate it has opened it. Here is the exception trace.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" color="#FF0000" face="Monaco" size="3"><SPAN class="Apple-style-span" style="font-size: 11px;">org.drools.rule.InvalidRulePackage: Unable to resolve ObjectType 'Message' : [Rule name=Hello World, agendaGroup=MAIN, salience=0, no-loop=false]</SPAN></FONT></DIV><DIV style="margin-top: 0px;
