    copied!<p>Using Drools 5.5.0.Final with Guvnor 5.5.0.Final with the sample mortgages package.</p> <p>When submitting REST json request with the following Batch Execution Command:</p> <pre><code>{ "batch-execution": { "lookup":"ksession1", "commands":[ { "insert":{ "out-identifier":"outApplicant", "return-object":"true", "object": { "Applicant":{ "age":17 } } } }, { "fire-all-rules":"" } ] } } </code></pre> <p>returns: 500 Internal Server Error</p> <pre><code>com.thoughtworks.xstream.converters.ConversionException: Applicant : Applicant ---- Debugging information ---- message : Applicant cause-exception : com.thoughtworks.xstream.mapper.CannotResolveClassException cause-message : Applicant class : org.drools.command.runtime.rule.InsertObjectCommand required-type : org.drools.command.runtime.rule.InsertObjectCommand converter-type : org.drools.runtime.help.impl.XStreamJson$JsonInsertConverter line number : -1 class[1] : org.drools.command.runtime.BatchExecutionCommandImpl converter-type[1] : org.drools.runtime.help..XSt...$JsonBatchExecutionCommandConverter version : null </code></pre> <p>The Applicant class is defined in the mortgages package within an XSD like so:</p> <pre><code>age:Whole number (integer) applicationDate:Date creditRating:Text name:Text approved:True or False </code></pre> <p><strong>How can I tell drools where to find the Applicant class?</strong> ( <em>which is defined in the mortgage sample as an XSD file</em>) </p> <p>knowledge-services.xml currently looks like this:</p> <pre><code>&lt;drools:grid-node id="node1"/&gt; &lt;drools:kbase id="kbase1" node="node1"&gt; &lt;drools:resources&gt; &lt;drools:resource type="PKG" source="http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/packages/mortgages"/&gt; &lt;/drools:resources&gt; &lt;/drools:kbase&gt; </code></pre> <p>I suspect that changing the REST json request to fully specify the package name for Applicant class might work. </p> <pre><code> ... "object": { "something.somethingelse.Applicant":{ "age":17 } } ... </code></pre> <p>But can't seem to find where the fully qualified package name for Applicant is declared? </p> <p>Acceptable answer must show an example which works without having to write java code, since the whole point of the REST interface is to access drools through a web service interface. </p> <p>Is there a spring configuration , or some other way to write the json request that will work?</p>
