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  {
    private static final Logger logger = LoggerFactory.getLogger(TaskResourceFactory.class);
    private static TaskService taskService;
    private static AbstractPlatformTransactionManager transactionManager;
    
    public TaskResourceFactory(TaskService tService, AbstractPlatformTransactionManager tManager) {
        TaskResourceFactory.taskService = tService;
        TaskResourceFactory.transactionManager = tManager;
    }
    public static LocalTaskService getTaskClient(TaskService taskService, AbstractPlatformTransactionManager transactionManager) {
        new TaskResourceFactory(taskService, transactionManager);    

        initializeSessionFactory(transactionManager);
        LocalTaskService returnBean = new LocalTaskService(taskService);       
        return returnBean;
    }

    public static void initializeSessionFactory(AbstractPlatformTransactionManager transactionManager) {
      
        ApplicationContext ctx = AppContext.getApplicationContext();         
        TaskSessionSpringFactoryImpl springFactory = (TaskSessionSpringFactoryImpl) ctx.getBean("springTaskSessionFactory");       
        TransactionManager taskTx = new CustomDroolsSpringTransactionManager(transactionManager);        
        springFactory.setTransactionManager(taskTx);    
        springFactory.initialize();
     }
}

When springFactory.initialize() calling TaskService class it throwing error.

my applicationContext.xml is:

krisverlaenen Sep 26, 2012 10:58 AM (in response to avneesh)

Hi,

I wasn't able to reproduce the exact issue (due to some missing classes and not having the same context setup), but here's an example that successfully loads the human task service:

        ClassPathXmlApplicationContext context =
            new ClassPathXmlApplicationContext("spring-conf.xml");

        TaskSessionSpringFactoryImpl springFactory =
            (TaskSessionSpringFactoryImpl) context.getBean("springTaskSessionFactory");
        springFactory.initialize();

        org.jbpm.task.service.TaskService internalTaskService =
            (org.jbpm.task.service.TaskService) context.getBean("taskService");
        TaskService taskService = new LocalTaskService(internalTaskService);
        System.out.println("Done setting up " + taskService);

With the following spring configuration file

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</bean>

</beans>

Hope this helps.

avneesh Sep 27, 2012 6:39 AM (in response to krisverlaenen)

Thanks krisv,

When I did changes as you told in previuos post. I am facing an error.

in spring-config file code is:

     <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
        <property name="url" value="jdbc:sqlserver://IITC-SRV-DB01:1433=RI" />
        <property name="username" value="***" />
        <property name="password" value="******" />
    </bean>

    <bean id="jbpmEMF" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="persistenceUnitName" value="org.jbpm.persistence.jpa.local" />
    </bean>

     <bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
        <property name="transactionManagerName" value="java:jboss/TransactionManager"/>
    </bean>

     <bean id="taskResourceFactory" class="com.nijhazer.jbpm.quickstart.TaskResourceFactory" factory-method="getTaskClient">
           <constructor-arg type="org.jbpm.task.service.TaskService"  ref="taskService" />
           <constructor-arg type="org.springframework.transaction.support.AbstractPlatformTransactionManager" ref="transactionManager" /> 
    </bean>

Here is TaskResourceFactory.java

public class TaskResourceFactory  {
    private static final Logger logger = LoggerFactory.getLogger(TaskResourceFactory.class);
    private static TaskService taskService;
    private static AbstractPlatformTransactionManager transactionManager;

    public TaskResourceFactory(TaskService tService, AbstractPlatformTransactionManager tManager) {
        TaskResourceFactory.taskService = tService;
        TaskResourceFactory.transactionManager = tManager;
    }
    public static LocalTaskService getTaskClient(TaskService taskService, AbstractPlatformTransactionManager transactionManager) {
        new TaskResourceFactory(taskService, transactionManager)
        initializeSessionFactory(transactionManager);
        LocalTaskService returnBean = new LocalTaskService(taskService);
        return returnBean;
    }

    public static void initializeSessionFactory(AbstractPlatformTransactionManager transactionManager) {
        ApplicationContext ctx = AppContext.getApplicationContext();  
        TaskSessionSpringFactoryImpl springFactory = (TaskSessionSpringFactoryImpl) ctx.getBean("springTaskSessionFactory");      
        springFactory.initialize();
        TaskService internalTaskService = (TaskService) ctx.getBean("taskService"); 
        LocalTaskService taskService = new LocalTaskService(internalTaskService); 
        System.out.println("Done setting up " + taskService)
      }
}

when springFactory.initialize() is called it throws exception:

15:51:36,660 INFO  [stdout] (MSC service thread 1-2) org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'taskResourceFactory' defined in class path resource

anything else I am missing to be change to get out from this exception krisv,

complete exception is attached:

Please suggest me.

krisverlaenen Sep 27, 2012 9:38 AM (in response to avneesh)

Hi,

This definitely seems to be a different error:
Caused by: java.lang.IllegalArgumentException: Named query not found: UnescalatedDeadlines

It's not picking up the query, which is defined in the Taskorm.xml file:
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-human-task/jbpm-human-task-core/src/main/resources/META-INF/Taskorm.xml#L938
This config file should be part of the jbpm-human-task-core jar

In your persistence.xml, do you have a reference to this config file (so it knows to load it), something like:
<mapping-file>META-INF/Taskorm.xml</mapping-file>

Looking at your server log, it seems it's trying to load it, but fails:
15:44:18,871 INFO [org.hibernate.ejb.Ejb3Configuration] (MSC service thread 1-2) HHH00360:Unable to resolve mapping file [classpath:Taskorm.xml]
Could it be that you missed the META-INF folder?

Hi Kris,

I put that file Taskorm.xml in META-INF and it is included in persistence.xml file.

Now it is showing this error:

krisverlaenen Sep 27, 2012 1:20 PM (in response to avneesh)

"org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory" can only happen if you have conflicting dom4j jars in your classpath somewhere. So it's likely you have either multiple versions of this jar in your application, or one in your application and for example one in the server lib folder.
