Configuring JTA with Activiti

suad — Sun, 21 Aug 2011 10:30:00 GMT

I am trying to configure activiti (5.6) to use Bitronix as Transaction Manager through JtaProcessEngineConfiguration. I am using MySQL as a database. Currently I am running the application as a standalone. I am getting the below exception.[2011-08-21 13:57:06,579] DEBUG main java.sql.PreparedStateme

for me setting the properties RelaxAutoCommit and ElideSetAutoCommits to true in the JDBC MySQL connection pool in Glassfish helped with this issue

Thanks for mentioning this Chris. I'd think the error was obvious as would have been searching for the answer in a glassfish forum or something. But thanks anyway

Hi Chris/Ronald,

I have tried setting the properties but I am still getting the same exception. Please note that I am using the XA datasource and not the regular datasource.

moreover, the same configuration (MySQL XA datasource + Bitronix) works fine in my application without using activiti. But once I integrate it with activiti I get the exception?

just one thought, because i have no other idea

did u try setting:


<property name="transactionsExternallyManaged" value="true" />

in the processEngineConfiguration?

when i asked regarding this problem at the Glassfish mailinglist i got answer
that it is defined in JDBC4 spec that after closing a transaction a JDBC driver
should set autocommit to true again, so statements executed outside of an
transaction gets commited immediately. So this behavior is ok i think. Maybe
setting the properties RelaxAutoCommit end ElideAutoCommit… did not work?

Does a Spring managed JTA transaction(with an implementation of Bitronix) and a Application Service (Glassfish) managed JTA transaction make any difference for Activiti?

If thay are not the same transaction manager, sure it makes a difference, not only for activiti, but for any system. 2 jta transaction managers does not make any sense at all to me

I think you misunderstood my question. The question should have be like this

Does a Spring managed JTA transaction(with an implementation of Bitronix) OR an Application Server (Glassfish) managed JTA transaction make any difference for Activiti?

So I did not misunderstand your question 😉 at least not fully

For Activiti, both need to be spring wrapped I would think. I've not seen a directly used jta manager in Activiti, but that can be a lack of knowledge from my side.

Hi Chris,

Thanks…. setting the property solved the issue.
