I believe that I have successfully integrated jBPM with Spring. However, I am still
having one issue. Section 17 of the jBPM Developer's Guide, seems to indicate that
Spring objects can be referenced in Juel expressions. However, I have not been able to
make this work. I get the stack trace:
Caused by: javax.el.PropertyNotFoundException: Cannot find property boNpcPaProcess
at de.odysseus.el.util.SimpleResolver.get(SimpleResolver.java:106)

My jbpm.cfg.xml looks as follows:

My Spring config is broken into several files. However, the relevant pieces are as
follows:
<bean id="springHelper"
class="org.jbpm.pvm.internal.processengine.SpringHelper" />
<bean id="processEngine" factory-bean="springHelper"
factory-method="createProcessEngine" />
<bean id="dataSource"
class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName"
value="jdbc/ScaGlobalDataSource" />
</bean>
<!-- Hibernate SessionFactory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- This config is for unit tests as the jar will not exist yet. -->
<!-- It does not work at runtime since the files will be located in a jar and
hibernate will not pick them up. -->
<property name="mappingLocations">
<value>classpath*:**/*.hbm.xml</value>
</property>
<!-- This config does not work for unit tests as the jar will not exist yet.
-->
<!-- It does work at runtime since the files will be located in a jar.
-->
<property name="mappingJarLocations">
<list>
<value>classpath*:**/services.jar</value>
<value>classpath*:**/jbpm-pvm-*.jar</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.Oracle10gDialect
</prop>
<prop key="hibernate.show_sql">false</prop>
<prop
key="hibernate.generate_statistics">false</prop>
</props>
</property>
<property name="configLocation"

<property name="eventListeners">

</property>
</bean>
I did see some examples where a "spring.cfg" string was set in the jBPM
configuration. Is this maybe needed?
<string name="spring.cfg"
value="applicationContext-services-pa.xml" />
Any help would be GREATLY appreciated!
Thanks in advance,
Ken
