Yes I understand how to deserialize a binary serialization of a KnowledgePackage. Let me explain the problem and what I'm trying to solve. <div><br></div><div>The case is that we have rules spread out between many files (not known until run time, these are then serialized and cached based on run keys and reused). Note too that these files have a precedence order from a programming perspective, not from a run perspective. The problem is in adding declared types to be used by these rule sets at a lower level rule (e.g. one that is more generic and more core). Then we put in a set of specialization rules that also need to use this declared type, sometimes this works but sometimes this won't compile because it says the type is not declared. In eclipse we found that if we put a .package file with the declared type in it then this specialization rule set compiles however we can't figure out how to propagate this into the runtime KnowledgeBase. It sounds like what your saying is that I made a wrong assumption. Is this kind of thing not possible? Is there a different mechanism for these generic types besides having them as pre-compiled java POJO's?</div><div><br></div><div><b>Example Rules Source:</b></div><div>I have a <i>blah.drl</i> like the following</div><div><div style="margin: 0px; font-size: 11px; font-family: Monaco; "><div style="margin: 0px; color: rgb(169, 21, 0); ">package<span style="color: #000000"> com.x</span></div><div style="margin: 0px; min-height: 15px; "><br></div><div style="margin: 0px; color: rgb(0, 143, 0); "><span style="color: #a91500">rule</span><span style="color: #000000"> </span>"A Thing"</div><div style="margin: 0px; "> <span style="color: #a91500">when</span></div><div style="margin: 0px; "> <span style="color: #a91500">then</span></div><div style="margin: 0px; "><span class="Apple-tab-span" style="white-space:pre"> </span>Blah blah = <span style="color: #a91500">new</span> Blah();</div><div style="margin: 0px; "><span class="Apple-tab-span" style="white-space:pre"> </span>blah.setX(<span style="color: #008f00">"123"</span>);</div><div style="margin: 0px; "><span class="Apple-tab-span" style="white-space:pre"> </span>blah.setY(<span style="color: #008f00">"321"</span>);</div><p style="margin: 0px; min-height: 15px; "><span class="Apple-tab-span" style="white-space:pre"> </span><br class="webkit-block-placeholder"></p><div style="margin: 0px; "><span class="Apple-tab-span" style="white-space:pre"> </span>System.out.println(<span style="color: #008f00">"X is "</span> + blah.getX());</div><div style="margin: 0px; "><span class="Apple-tab-span" style="white-space:pre"> </span>System.out.println(<span style="color: #008f00">"Y is "</span> + blah.getY());</div><div style="margin: 0px; color: rgb(169, 21, 0); ">end</div></div><div style="margin: 0px; font-size: 11px; font-family: Monaco; min-height: 15px; "><br></div></div><div style="margin: 0px; min-height: 15px; ">and I have a <i>blah.package</i> like the following</div><div style="margin: 0px; font-size: 11px; font-family: Monaco; min-height: 15px; "><div style="margin: 0px; "><div style="margin: 0px; color: rgb(169, 21, 0); ">package<span style="color: #000000"> com.x</span></div><div style="margin: 0px; min-height: 15px; "><br></div><div style="margin: 0px; color: rgb(169, 21, 0); ">declare<span style="color: #000000"> Blah</span></div><div style="margin: 0px; "> x : String</div><div style="margin: 0px; "> y : String</div><div style="margin: 0px; color: rgb(169, 21, 0); ">end</div></div></div><div><br></div><div>Thanks, <br><div apple-content-edited="true"><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px; "><br></span></div><div apple-content-edited="true">
