The hibernate mappings were put into the person.hbm.xml file:
<?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.sample.model" auto-import="false" default-access="field"> <class name="Person"> <id name="ssn" column="SSN"><generator class="native" /></id> <property name="lastname" column="LASTNAME" /> <property name="firstname" column="FIRSTNAME" /> </class> </hibernate-mapping>

The path to the missing interface we traced from jbpm-jpdl.jar -> org.jbpm.context.exe -> jbpm.varmapping.xml file contains the following mapping:
<!-- JSR 170 JCR Node -->
<jbpm-type>
<matcher>
<bean class="org.jbpm.context.exe.matcher.JcrNodeMatcher" />
</matcher>
<variable-instance class="org.jbpm.context.exe.variableinstance.JcrNodeInstance" />
</jbpm-type>
This leads to org.jbpm.context.exe.matcher.JcrNodeMatcher.class which imports the class not included in jBPM:
/*
* Snipped the license code.
*/
package org.jbpm.context.exe.matcher;
import javax.jcr.Node; <<<<<<<<<<<<<< MISSING!!!!
import org.jbpm.context.exe.JbpmTypeMatcher;
public class JcrNodeMatcher implements JbpmTypeMatcher {
private static final long serialVersionUID = 1L;
public boolean matches(Object value) {
return (Node.class.isAssignableFrom(value.getClass()));
}
}
My solution: added external jar to projects classpath, jcr-1.0.jar which provides the needed interface interface. Hope this saves you some time!
