Database queries result in NoClassDefFound for org/wildfly/transaction/client/ContextTransactionManager ------------------------------------------------------------------------------------------------------- Key: WFLY-10996 URL: https://issues.jboss.org/browse/WFLY-10996 Project: WildFly Issue Type: Bug Components: JPA / Hibernate Affects Versions: 14.0.1.Final, 14.0.0.Final Environment: CentOS 7/Mac OS WildFly 14.0.0 / WildFly 14.0.1 Reporter: Rakesh K. Cherukuri Assignee: Scott Marlow Priority: Blocker Attachments: error.log, jpa-war.tar.gz, pgsql.driver.tar.gz, standalone-full.diff Basically WildFly is unable to either build the persistence context or it fails to query postgres db. The changes are so minimal that it should basically work. Attached: # error.log - exception in the server log # jpa-war.tar.gz - maven module that can be used to reproduce the issue # pgsql.module.tar.gz - postgres driver module that can be unpacked under modules/system/layers/base/org/postgresql # standalone-full.diff - diff that can be applied to standalone-full.xml to define required datasource Note: - Tested same steps with wildfly 13 and there its woking fine. - Tested with latest postgres driver and issue exists with v14.0.0 (and v14.0.1). Postgres driver is thus ruled out.
