<b>Subject:</b> [rules-users] Rule Validation/Package Build Error in Guvnor:
ClassNot Found<o:p></o:p></span></p>
</div>
<p class=MsoNormal><o:p> </o:p></p>
<p>Hello,<o:p></o:p></p>
<div>
<p class=MsoNormal>I am new to Drools and have written a rule .DRL file which
contains some <br>
helper function imports from other packages, fact objects imports from <br>
other packages and the rules that act on these facts. The file works well <br>
when I call it from my javacode using the rulebase or knowledgebase approach. <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>The drl file itself is in its own package.<o:p></o:p></p>
</div>
<p>I now have a requirement to call the same rules from within Guvnor.<br>
The goal is to enable business users modify these rules through the <br>
Guvnor UI and also take advantage of the disable individual rules <br>
feature within guvnor.<o:p></o:p></p>
<div>
<p class=MsoNormal>My current difficulty is importing and validating the rules
in guvnor, <br>
along with the associated fact jar files and finally interfacing <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>with guvnor from my code. Any help would be appreciated .<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>The main error happens when I try to build a binary package
and create<br>
a snapshot of the working rule file I imported for deployment.<br>
When I hit the save and validate configuration button, I get<br>
<strong>"class not found"</strong> validation errors for all the
classes imported at <br>
the top of the rule file - includingng the helper import functions<br>
and facts used in the rules. Same thing happens when I try to <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>build the package I get the following errors <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>"Error importing: <list of all classes in import
statement in rule file>"<o:p></o:p></p>
</div>
<p>Here are the steps I followed in importing the rule file and Jar file
containing the classes<br>
into Guvnor<o:p></o:p></p>
<div>
<p class=MsoNormal>(1) First within Guvnor I created a package corresponding to
the package path<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>for for each of the jar files whose classes are
referenced/imported in the rule .DRL file<o:p></o:p></p>
</div>
<p>(2) I created the jar files for each of these packages in eclipse<o:p></o:p></p>
<p>(3) Imported those jars individually into each of the packages created in
guvnor <br>
using upload model jar function and selecting the
appropriate path as<br>
created in step 1 2 above<o:p></o:p></p>
<p>(4) Imported the rule file which is in its own package - using the create
package (upload method)<o:p></o:p></p>
<p>(5) I then try to save and validate the imported rule file in step
5 (this is where the error occurs)<o:p></o:p></p>
<p><br>
I have already setup my code to call guvnor as follows<o:p></o:p></p>
<p>RuleAgent agent = RuleAgent.newRuleAgent("guvnor.properties");<br>
RuleBase masterRuleBase = agent.getRuleBase();<o:p></o:p></p>
<p>guvnor.properties contains only one entry<br>
url = <a
href="http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/SomePackage.drools/LATEST">http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/SomePackage.drools/LATEST</a><o:p></o:p></p>
<p>It is my understanding that after I import the rule file<br>
I need to save and validate and build the package<br>
in order to point the url to the path above. If I point the url to just<br>
the drl file itself will it work?<br>
i.e url=<a
href="http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/SomePackage.drools/LATEST.drl">http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/SomePackage.drools/LATEST.drl</a>
<br>
<o:p></o:p></p>
<p>Any help to resolve the class not found error will <br>
be much appreciated<o:p></o:p></p>
<p>Thanks<o:p></o:p></p>
