[rules-users] Transaction problems in high concurrency JBPM+Drools+Hibernate instalation

[lautaro.chiarle]

Hi jwest,

I've uploaded a .zip file (sancor-test-cases.zip) with a "mavenized" project
you can use as example.

It includes a JUnit test called ar.com.sancor.test.ConcurrentServiceTest,
which builds an Spring context to start a JBPM engine and attemps to start 2
processes simustaneously.

The DB used is Derby, but you can change it to any robust DBMS you want.


The result we are getting is:
org.springframework.transaction.UnexpectedRollbackException: JTA transaction
unexpectedly rolled back (maybe due to a timeout);


Please let me know any issue you find executing the Test Case.

Thanks in advance,

sancor-test-cases_v3.zip
