<p class=MsoNormal>Has anyone successfully implemented a push model for
updating rules in a Drools 5.0 application? Here’s what I’d like to
do:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>1.<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Rules will be authored out-of-process, and serialized
KnowledgePackages will be stored in a database.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>2.<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>When the client application starts up (i.e. a regular
servlet-based app) it will fetch the KnowledgePackages from the database and
use them to configure a singleton KnowledgeBase instance.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>3.<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>A special UI in the client application will allow authorized
users to upload new KnowledgePackages. When new packages are uploaded they are
first persisted in the database and then used to update the KnowledgeBase at
runtime. All subsequent calls to fireAllRules() should use the rules in the new
package.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If anyone has done something like this before then I’d
appreciate some advice on how to manage updates to the KnowledgeBase at runtime.<o:p></o:p></p>
