--------------------------------------------------------------
All,
I have been able to make some progress in terms of integrating my current project with
jbpm, based on the link below:
http://captaincaveman.posterous.com/jbpm-43-spring-3-jboss-jpa-jta-config...
http://captaincaveman.posterous.com/jbpm-43-spring-3-jboss-jpa-jta-config...
With minor modifications, the set up was pretty much close. However, after all the
configuration changes are done, I do face this error during server start-up.

I do have the
jbpm.jar file in the classpath (it's in the WEB-INF\lib folder.)
This is bit of a suprise to me. Has anybody faced similar problem?
System configuration:
RAD 7.5 and WAS 7.0.0.15 Test Environment on Windows XP SP3.
DB server: SQL Server.
I added the following to my already working spring applicationContext.xml file:
<!-- Added for JBPM START -->
<!--
Activates a load-time weaver for the context. Any bean within the context that
implements LoadTimeWeaverAware (such as LocalContainerEntityManagerFactoryBean)
will receive a reference to the auto-detected load-time weaver.
-->
<!-- <context:load-time-weaver aspectj-weaving="on" />-->
<!--
Turn on AspectJ @Configurable support. As a result, any time you
instantiate an object, Spring will attempt to perform dependency
injection on that object. This occurs for instantiation via the "new"
keyword, as well as via reflection. This is possible because AspectJ
is used to "weave" Roo-based applications at compile time. In effect
this feature allows dependency injection of any object at all in your
system, which is a very useful feature (without @Configurable you'd
only be able to dependency inject objects acquired from Spring or
subsequently presented to a specific Spring dependency injection
method). Roo applications use this useful feature in a number of
areas, such as @PersistenceContext injection into entities.
-->
<context:spring-configured />
<!--
This declaration will cause Spring to locate every @Component,
@Repository and @Service in your application. In practical terms this
allows you to write a POJO and then simply annotate the new POJO as an
@Service and Spring will automatically detect, instantiate and
dependency inject your service at startup time. Importantly, you can
then also have your new service injected into any other class that
requires it simply by declaring a field for your service inside the
relying class and Spring will inject it. Furthermore, this turns on
@Autowired, @PostConstruct etc support. These annotations allow you to
use common Spring and Java Enterprise Edition annotations in your
classes without needing to do any special configuration. The most
commonly used annotation is @Autowired, which instructs Spring to
dependency inject an object into your class.
-->
<context:component-scan base-package="com.test" />
<!-- enables interpretation of the @Required annotation to ensure that dependency
injection actually occurs -->
<bean
class="org.springframework.beans.factory.annotation.RequiredAnnotationBeanPostProcessor"/>
<!--
Activates various annotations to be detected in bean classes: Spring's
@Required and @Autowired, as well as JSR 250's @PostConstruct,
@PreDestroy and @Resource (if available) and JPA's @PersistenceContext
and @PersistenceUnit (if available).
-->
<context:annotation-config
transaction-manager="transactionManager" />
<!--
Instruct Spring to retrieve and apply @AspectJ aspects which are
defined as beans in this context.
-->
<!-- <aop:aspectj-autoproxy proxy-target-class="true" />-->
<!--
The JNDI Hibernate session factory will not work for jBPM 4.4 as jBPM is
expecting
a Spring LocalSessionFactoryBean. So we specify our mappings here. This will
only
be used by jBPM. Spring will still inject the container managed persistence unit
anywhere you use @PersistenceContext.
-->
<!-- <jee:jndi-lookup id="sessionFactory"
jndi-name="java:/SquareOneHibernateSessionFactory" /> -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<!-- <property name="configLocation"
value="classpath:/jbpm/jbpm.hibernate.cfg.xml" /> -->
<property name="dataSource" ref="dataSource" />
<property name="mappingResources">
<list>
<value>jbpm.repository.hbm.xml</value>
<value>jbpm.execution.hbm.xml</value>
<value>jbpm.history.hbm.xml</value>
<value>jbpm.task.hbm.xml</value>
<value>jbpm.identity.hbm.xml</value>
</list>
</property>
<!--
Hibernate properties needed to configure the session factory to use JTA.
This will ensure that jBPM can participate in the application's JTA
transactions.
-->
<property name="hibernateProperties">
<props>
<prop
key="hibernate.transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</prop>
<prop
key="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.WebSphereTransactionManagerLookup</prop>

<prop key="hibernate.hbm2ddl.auto">false</prop>
<!-- <prop
key="hibernate.default_schema">dbo</prop>-->
</props>
</property>
</bean>
<!-- jBPM beans.
Based on the jBPM provided way of creating a Spring process engine set up.
This can also be done by calling the Process engine methods with parameters
directly.
However this is the most appropriate way of initializing jBPM.
-->
<!-- <util:properties id="my_jbpm_config"
location="classpath:/resources/my.jbpm.cfg.xml"/>-->
<bean id="springHelper"
class="org.jbpm.pvm.internal.processengine.SpringHelper">
<property name="jbpmCfg"
value="/WEB-INF/resources/my.jbpm.cfg.xml"/>
</bean>
<bean id="processEngine" factory-bean="springHelper"
factory-method="createProcessEngine" scope="singleton"/>
<!-- Added for JBPM END -->
Any pointers will be of great help.
Thanks,
