Hi,
When I am trying to create Local Task Service for jbpm human task using spring framework. It throwing exception.
I have a java class
TaskResourceFactory.java
public class TaskResourceFactory implements ApplicationContextAware {
private static final Logger logger = LoggerFactory.getLogger(TaskResourceFactory.class);
private static ApplicationContext context;
private static TaskService taskService;
private static AbstractPlatformTransactionManager transactionManager;
@Override
public void setApplicationContext(ApplicationContext applicationContext)
throws BeansException {
this.context = applicationContext;
}
public TaskResourceFactory(TaskService tService, AbstractPlatformTransactionManager tManager) {
TaskResourceFactory.taskService = tService;
TaskResourceFactory.transactionManager = tManager;
}
public static LocalTaskService getTaskClient(TaskService taskService, AbstractPlatformTransactionManager transactionManager) {
initializeSessionFactory(transactionManager);
logger.debug("Creating local task service client, based on {}",taskService);
LocalTaskService returnBean = new LocalTaskService(taskService);
logger.debug("Returning task client: {}", returnBean.toString());
return returnBean;
}
public static void initializeSessionFactory(AbstractPlatformTransactionManager transactionManager) {
logger.debug("Initializing the session factory");
TaskSessionSpringFactoryImpl springFactory = (TaskSessionSpringFactoryImpl) context.getBean("springTaskSessionFactory");
logger.debug("Setting the transaction manager, based on {}",transactionManager);
TransactionManager taskTx = new DroolsSpringTransactionManager(transactionManager);
springFactory.setTransactionManager(taskTx);
logger.debug("Initializing");
springFactory.initialize();
}
public TaskService getTaskService() {
return taskService;
}
public void setTaskService(TaskService taskService) {
this.taskService = taskService;
}
public AbstractPlatformTransactionManager getTransactionManager() {
return transactionManager;
}
public void setTransactionManager(
AbstractPlatformTransactionManager transactionManager) {
this.transactionManager = transactionManager;
}
When *springFactory* object is to be create it throwing exception.
my applicationContext.xml is:
<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="transactionManagerName" value="java:jboss/TransactionManager"/>
