EJB transactional method unable to commit when invoked from CDI bean with MariaDB --------------------------------------------------------------------------------- Key: WFLY-11543 URL: https://issues.jboss.org/browse/WFLY-11543 Project: WildFly Issue Type: Bug Components: JPA / Hibernate Affects Versions: 15.0.0.Final Environment: WildFly 15.0.0.Final MariaDB 10.1.19 Reporter: Michal Jurc Assignee: Scott Marlow Priority: Blocker Attachments: logs.zip, server-trace.zip Issue cloned from the [community forum|https://developer.jboss.org/thread/279303] for tracking. {quote}Hello, We are having issues after deploying our application in the latest Wildfly 15.0.0 Final recently released with the following exception: java.sql.SQLException: XAER_RMFAIL: The command cannot be executed when global transaction is in the IDLE state The error occurs when our code calls a transactional EJB method that itself calls a couple more injected SessionBean that handles the database persistence through an EntityManager The issue only seems to affect the MariaDB port and not oracle.{quote} {quote}I have hit the same problem, migrated from Wildfly 10.0.0. to 15.0.0, using MySQL, same error, similar situation, cdi managed bean that invokes 2 EJBs that use different persistent units. I dont seem to have the problem in 14.0.1 either. Another error that has surfaced is this (apologies for the weird formatting but struggled to define a simple type-up without cluttering) "javax.persistence.TransactionRequiredException: no transaction is in progress" Managed bean with injected ejb (with datasource2) and injected entitymanager for datasource1, code is nested as follows Managed bean method save @Transactional(value = TxType.REQUIRED) { ejb save @TransactionAttribute(TransactionAttributeType.MANDATORY) { persist flush } find with lock => LockModeType.PESSIMISTIC_WRITE at this point the "no transaction is in progress" exception is fired } Did notice that error does not occur if the invocation is purely ejb rather that cdi managed bean {quote}
