I tried adding the classloader to the JPA classes to the RuleBaseConfiguration but that had no effect. After much code digging, debugging and research I decided to setShadowProxy(false) on the RuleBaseConfiguration and low-and-behold things worked. No sure why Drools can't create the proxies for the JPA classes. I will save that for the next rainy day.<br><br>Earnie1<br></div><div style="font-family: tahoma,new york,times,serif; font-size: 10pt;"><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><font size="2" face="Tahoma"><hr size="1"><b><span style="font-weight: bold;">From:</span></b> Earnest Dyke <earniedyke@yahoo.com><br><b><span style="font-weight: bold;">To:</span></b> JBoss Rules

<div style="font-family: tahoma,new york,times,serif; font-size: 10pt;"><div>Greetings all,<br><br>I am trying to use Drools 4.0.7 with objects that are retrieved via OpenJPA. So I have a Person entity which is in the package <a target="_blank" href="http://com.my">com.my</a>.company.entity. When I retrieve it via OpenJPA what I get, and subsequently insert into working memory, is a org.apache.openjpa.enhance.com$my$company$entity$Person$pcsubclass. I have tried casting before inserting into working memory but that does not change things. Drools is throwing <span style="font-weight: bold;">java.lang.NoClassDefFoundError: org/apache/openjpa/enhance/com$my$company$entity$Person$pcsubclass</span> exception. <br><br>Any ideas of how to get around this? I really don't want to have to declare the concrete (OpenJPA) classes in my rules if I can help it.<br><br>Thanks in advance for any and all
help!<br><br>Earnie!<br><br><br></div></div></div></div></div></body></html>
