HI Michael,

Thank You for your reply. Even I am having the same configuration in my jbpm.cfg.xml file. Then I have tried with reinstantiate the ExecutionService factory as

executionService = processEngine.getExecutionService();

Then after that it starts working. Before I give the transaction management I was getting the lazyinitialization exception while trying to access the properties of the jbpm process variable objects. But after I configure the transaction management as follows:

<bean id="jbpmContextServiceTarget" class="com.collabera.poc.jbpm.impl.JBPMContextServiceImpl"

            init-method="init">

            <property name="processEngine">

                  <ref bean="processEngine" />

            </property>

            <property name="checking">

                  <ref bean="checking" />

            </property>

<bean id="jbpmContextService" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">

    <property name="transactionManager"><ref bean="transactionManager"/></property>

    <property name="target"><ref bean="jbpmContextServiceTarget"/></property>

    <property name="transactionAttributes">

        <props>

            <prop key="deploy*">PROPAGATION_REQUIRED</prop>

            <prop key="*">PROPAGATION_REQUIRED</prop>

        </props>

    </property>

</bean>

And try to do a transition using executionService  I am getting the exception saying that "

Exception in thread "main"

org.jbpm.api.JbpmException: execution ddrRequest.400008 does not exist

at org.jbpm.pvm.internal.cmd.SignalCmd.execute(

SignalCmd.java:58)

at org.jbpm.pvm.internal.tx.SpringCommandCallback.doInTransaction(

SpringCommandCallback.java:45)

at org.springframework.transaction.support.TransactionTemplate.execute(

TransactionTemplate.java:128)

I am getting this exception when I am using the ExecutionService instance to access the process instance.

In my analysis the problem is as the transaction is active and session is opened the JBPM4_EXECUTION table is not getting updated and the

executionService

processEngine.execute(new Command() {
    public Object execute(Environment env) {
        // do something.
        return null;
    }
});
why do we need this?

Can anybody please send me a solution for the same.

Thank you and regards,
