    integrating spring 2.5.6 with jbpm 4.3

    praneet nandan Newbie

      hello every one

        to configure spring with jbpm 4.0 i used to write following code in applicationcontext.xml

       

      <bean id="jbpmConfiguration" class="org.jbpm.pvm.internal.cfg.SpringConfiguration">

      <property name="sessionFactory" ref="sf"></property>

      <constructor-arg value="jbpm.cfg.xml"></constructor-arg>

      </bean>

       

       

      but the above class (org.jbpm.pvm.internal.cfg.SpringConfiguration)

      is not present in jbpm 4.3 then how to integrate in 4.3

          This appears to have been changed.  I just started with jBPM and seem to have it all up and running under Spring.  My Spring configuration looks like this:

           

           

          <bean id="springHelper" class="org.jbpm.pvm.internal.processengine.SpringHelper" />
          
          <bean id="processEngine" factory-bean="springHelper" factory-method="createProcessEngine" />
          
          <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" value="classpath:jbpm.hibernate.cfg.xml" />
                    
               <property name="eventListeners">
                    <map>
                         <entry key="merge">
                              <bean class="org.springframework.orm.hibernate3.support.IdTransferringMergeEventListener" />
                      </entry>
                    </map>
               </property>
          </bean>

            Hi Praneet,

             

            You also do not specify your persistence needs.  The post above will work if you are using plain hibernate.  You will need a different configuration though if you are using hibernate with JPA.

             

            This thread should be of help in case you need to configure Spring with jBPM 4.3 and you are using JPA:  http://community.jboss.org/thread/147177?tstart=0

             

            Specifically, I wrote about it here:  http://captaincaveman.posterous.com/jbpm-43-spring-3-jboss-jpa-jta-configuration

             

            Hope it helps.

                Could you please post your configuration so we can see what might be wrong?  Please post your applicationContext.xml and jbpm.cfg.xml
