question about Activit Transactions interfering with other transactions?

[aruna]

Hi,
I am new to Activiti and am writing a simple scenario where I create a service task. This service task  calls a delegate which is turn calls another service which interacts with database. I want my service to be a black box to activiti. All I need is that it calls the service and prints out the objects returned by the service.
My service works when called outside of Activiti. But when I call the service through Activit it throws Lazy Loading exception.
The transaction management is handled within my service and I do not use the transaction created by Activiti.
Activiti uses in memory databse, while my service uses Oracle.
Can Activiti be interfering with the transactions in my service?

This is the exception that is thrown. The Junit test case which the same method in my service works without any problems.

Yes they are annotation driven. and they are all managed within broadleaf, an open source order management system that my services uses.

[frederikherema1]

Yes, but why is that piece of the XML commented out? This way, transactions aren't hooked up in the services you use…

[aruna]

I don't want to pass any transactions from activity to my services. As I mentioned my service should be a black box to Activity. You can assume that my service just returns a String back to Activity. What happens within my services should not matter to activity.

[frederikherema1]

Aruna, If I should consider it as a black box, why are you asking questions about transactions IN your services? I just want to help you and figure out how your services get THEIR transactions wired in, regardless of actviti's transactions… If the black box doesn't work as it should, it's either not configured the way it should or using the wrong transaction-manager.

[aruna]

The reason I was asking was because the service works fine when I call it from a Junit test but when I started calling it from Activiti I started getting the exception I mentioned in my post. I was wondering if somehow Activit's transaction was interfering with my service. Since I don't know the internals of Activiti I thought I would ask to see if that was possible. From what I understand, Activiti would open a connection and then call my service, but my service will create its own connections and transactions, but could the open connection/transaction of Activity cause any problems?

[frederikherema1]

If activiti uses TransactionManager 1 and your services use TransactionManager 2, there is NO way of activiti interfering with the service-transactions. However, in your examples, I don't see how the transactions for your black-box services are configured. Make sure the use a different transaction-manager for the behaviour you're trying to do.

If the JUnit-test works, you should just take that spring-context and throw in the activiti-beans and it should continue to work.

[amenting]

For me, the problem only ceased to exist after i injected the entity manager into the jpaEntityManagerFactory property, but maybe that is just because i am configuring the spring boot way in code (everything else is pretty standard spring boot default setup - transaction management should be set up in boot by default, if i read the documentation correctly, but it did not work for me in version 5.20.0).
