<p>6) Incorrect (well, almost.. read on). "Real time" would imply instant, zero latency, whereas for many use cases "close to real time" is often sufficient. If you read about KieScanner you will find you can have your application poll for updates to JARs*
at a frequency you so desire.<o:p></o:p></p>
<p>(*) There are certain caveats that relate to standard maven best practice; for example if your JAR has a static version number (e.g. 1.0.0) you should not be changing its content (wheras a -SNAPSHOT is expected to change).<o:p></o:p></p>
<p>7) Drools itself does not impose any SDLC; you can use whatever you wish. Others who have used Drools in their applications may detail their experiences.

<p class="MsoNormal">Sorry for follow-on basic questions. I am starting from scratch and therefore<br>
do not have any Drools experience.<br>
<br>
Already answered ...<br>
<br>
1) Drools workbench/Guvnor is not a replacement for Eclipse.* - Correct*<br>
2) Geeks like me develop the applications in Eclipse* - Correct*<br>
3) Drools workbench will be mainly used by the Rule authors (Business<br>
Analysts etc) once I set it up for them.* - Correct*<br>
4) The anslysts will author the rules and test it in the workbench.* -<br>
Correct*<br>
5) They will build the DRLs into a jar and I include it as a dependency in<br>
my POM.xml.* - Correct*<br>
<br>
Additional questions because I am new to Drools<br>
<br>
6) Based on the answer to (5) the concept of "real time rule replacement"<br>
does not exist. After the rules jar has been put into the Maven repository I<br>
need to build my application and deploy it ... i.e. stop the currently<br>
running application, remove it, install the new application and restart it.<br>
<br>
7) If someone can point me at high level documentation related to "the<br>
complete Drools 6.0 rule software development lifecycle" ... i.e. from rule<br>
creation to actually executing in a production environment ... I would<br>
appreciate it.<br>
<br>
I have been asked to do a Proof of Concept. There is the impression I will<br>
be able to prove that "the business will be able to create their own rules<br>
and deploy them into production without any IT intervention". I do not<br>
believe this to be the case ... best SDLC practices not withstanding ... but<br>
have not been able to find a Drools SDLC picture that shows all of the steps<br>
necessary.<br>
<br>
Thanks,<br>
