Yes, you can compile your rules once and save them as binary files. Here is a code snippet to do that:<div><br></div><div><div> <i> KnowledgePackage pkg = (KnowledgePackage) kbuilder</i><span class="Apple-tab-span" style="white-space:pre"><i> </i></span><i>.getKnowledgePackages().iterator().next();</i></div>
</div><div><div><i> FileOutputStream out = new FileOutputStream("/some/file.pkg");</i></div><div><span class="Apple-tab-span" style="white-space:pre"><i> </i></span><i>try {</i></div><div><span class="Apple-tab-span" style="white-space:pre"><i> </i></span><i>DroolsStreamUtils.streamOut(out, pkg);</i></div>
<div><span class="Apple-tab-span" style="white-space:pre"><i> </i></span><i>} finally {</i></div><div><span class="Apple-tab-span" style="white-space:pre"><i> </i></span><i>out.close();</i></div><div><span class="Apple-tab-span" style="white-space:pre"><i> </i></span><i>}</i></div>
</div><div><br></div><div>The code above only uses kbuilder's first package.</div><div>The way you load a binary package is the same as you do for DRL files:</div><meta http-equiv="content-type" content="text/html; charset=utf-8"><div>
<span class="Apple-tab-span" style="white-space: pre; "><br></span></div><div><span class="Apple-tab-span" style="white-space: pre; "> </span><i>kbuilder.add(ResourceFactory.newFileResource("/some/file.pkg", ResourceType.PKG); </i></div>
<div><br></div><div>Hope you find this useful!</div><div><br></div><div>Best,</div><div><br><div class="gmail_quote">2010/5/17 Adeyinka Timi <span dir="ltr"><<a href="mailto:adeyinka.timi@nathean.com">adeyinka.timi@nathean.com</a>></span><br>
