Can I have acces to custom beans without Spring?

[gsvano]

Hi everyone!
I tried get access to my service to set dueDate in UserTask but.. fail

<userTask id="bidSelection" activiti:dueDate="${dateService.getDueDate()}" …‍

I tried set beans

Map<Object, Object> beans = new HashMap<Object, Object>();
beans.put("dateService", dateService);
((ProcessEngineConfigurationImpl) configuration).setBeans(beans);‍‍‍

but got same exception

Caused by: org.activiti.engine.impl.javax.el.PropertyNotFoundException: Cannot resolve identifier 'dateService'
   at org.activiti.engine.impl.juel.AstIdentifier.eval(AstIdentifier.java:83)

As far I understand I should use Spring for it but my project not use Spring (I use EJB and CDI).
Are there any way to get my services beans in this case?
Maybe I do something wrong?
Thanks!

I suppose you have to set up your bean in your application context, in your spring configuration context you need something like this:

<bean id="dateServicer" class="org.activiti.yourpackage.dateService" />
Read the chapter about Use Activiti with Spring on "Activiti in Action" Book.
Let me know

Yes, you right it will work, but I want find way to set beans without Spring.
I want to use them out of processes.

Maybe you can use a DelegateExpression, it's work but if you'll use this your bean must implement JavaDelegate

Any examles?
I want use it in UserTasks to set DueDate field.

Ok, I found solution

Should add the Expression manager into configuration
ProcessEngineConfiguration configuration = CdiStandaloneProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();
configuration.setExpressionManager(new CdiExpressionManager());and to use standart cdi annotations

@Named
public class DateService {
    public Date getDueDate() {
        …
    }
}
