<div dir="ltr">Micheal is right in that using RMI more tightly couples you to the underlying asset object model, but it also gives you a lot of flexibility. For instance, every time our object model changes, as part of the build process, the package is created/updated to include the updated JARS, updated header section, and updated code for the enumerations. It will then validate the package, build it, and create a new snapshot with the version of the model.<br>
<br>To Micheal's point, I had to update my code to handle the change in the way header is stored in BRMS vs. Guvnor. In BRMS it was a property on the PackageItem, but now it is an AssetItem in the package.<br><br>Here is a sample of connecting to the JCR, then using said session with the Drools API<br>

Is it possible to share the code snippet with us. I don't have any experience of Jackrabbit and RMI. Any concrete example will be helpful.<div class="Ih2E3d"><br>

Hi Leo,<br>
<br>
I use the Drools API to interact with the JCR with I expose over RMI. I have the security on Jackrabbit, so I log into the JCR, not BRMS. But once the session is established I use the org.drools.repository.RulesRepository to work with BRMS artifcacts as opposed to JCR ones.<br>
<br>
hope that makes sense,<br>

Hi David,<br>
<br>
You mean going around Drools Api and acessing the JCR directly?<br>
<br>
I really wanted the BRMS to expose an interface to add things.<br>
That would provide more security on upgrading versions without<br>
breaking functionality.<br>
<br>

Guys,<br>
<br>
I use the Drools API over RMI. Jackrbait provides an RMI<br>
implementation to manipulate the JCR, and the Drools<br>
RulesRepository class works with an open JCR session object.<br>
Really is a pieice of cake; that is if an RMI solution is ok<br>
with you. You can always go RMI over HTTP too.<br>

Hi Leo,<br>
<br>
Thanks for your reply. You are absolutely correct, I<br>
was talking about API to upload rules, either using<br>
Restlet API or WebDav Client API or Drools API. I have<br>
read the article mentioning the support for Restlet Web<br>
Services and Webdav but haven't seen any such example yet.<br>
If only Drools Guvnor supports such features, I am fine<br>
with Drools 5.0.<br>
<br>
Leo, it will be be nice of you if you can share your<br>
homemade customized Servlet. Your sharing of ideas and<br>
experience will be appreciated.<br>
<br>
Cheers<br>

Hi,<br>
<br>
You mean using an api to add rules to the BRMS? If so<br>
i have the same problem. I am using an "homemade"<br>
build that have a custom Servlet that allows me to<br>
pass an DRL to be added to the BRMS.<br>
<br>
I am still searching for a better solution.<br>
<br>

Hi,<br>
<br>
I was wondering if it is possible to create and<br>
upload rules at<br>
runtime to BRMS to be accessed by other users. I<br>
have only seen<br>
the examples where existing packages/rules are<br>
loaded from the<br>
BRMS. Any help and suggestion will be appreciated.<br>
<br>
Cheers<br>
