<u></u><u></u></p><p class="MsoNormal" style="margin-bottom: 12pt;">Serializing a compiled package seems a rational thing to do - after all, there is: <resource source="..." type="PKG" /> and it is recognized by the monitor.<br>
<br>However, you can't simply serialize an org.drools.definition.KnowledgePackage as it is usually done by writing it to an ObjectOutputStream: deserialization in the KnowledgeAgent throws a CCE exception. To make it work, you must use a DroolsObjectOutputStream, which is nothing but a rename of ObjectOutputStream. So I have use DroolsObjectOutputStream, but it is not part of the public API.<br>
