[jboss-jira] [JBoss JIRA] Issue Comment Edited: (JBAS-9155) jboss processes only one persistence.xml file per war file

jboss processes only one persistence.xml file per war file ----------------------------------------------------------- Key: JBAS-9155 URL: https://issues.jboss.org/browse/JBAS-9155 Project: Legacy JBoss Application Server 6 Issue Type: Bug Security Level: Public(Everyone can see) Components: JPA / Hibernate Affects Versions: 6.0.0.Final Reporter: Vincent A Assignee: Ales Justin Labels: deployment, jboss, jpa, persistence, war Fix For: 6.1.0 If a war file contains several Persistence Archive jars, JBoss starts only the persitence unit(s) defined in the first jar it scans, ignoring the remaining ones. For instance, given the following war file: {code} my-war +-- WEB-INF +-- lib +-- pu1.jar +-- META-INF + persistence.xml // <persistence-unit name="pu1" >...</persistence-unit> +-- pu2.jar +-- META-INF + persistence.xml // <persistence-unit name="pu2" >...</persistence-unit>}} {code} Jboss will only starts the pu1 persistence unit. And if the war file has the following structure: {code} my-war +-- WEB-INF +-- classes +-- META-INF + persistence.xml // <persistence-unit name="pu0" >...</persistence-unit> +-- lib +-- pu1.jar +-- META-INF + persistence.xml // <persistence-unit name="pu1" >...</persistence-unit> +-- pu2.jar +-- META-INF + persistence.xml // <persistence-unit name="pu2" >...</persistence-unit> {code} Jboss starts pu0, and skips the PU's defined in pu1.jar and pu2.jar. This behaviour is non-compliant. Section 6.2 of the spec states that: {quote} A persistence unit may be packaged within one or more jar files contained within a WAR or EAR, as a set of classes within an EJB-JAR file or in the WAR classes directory, or as a combination of these as defined below. {quote} [...] {quote} It is not required that an EJB-JAR or WAR containing a persistence unit be packaged in an EAR unless the persistence unit contains persistence classes in addition to those contained in the EJB-JAR or WAR. {quote} And from section 7: {quote} 7.1.1 Responsibilities of the Container At deployment time the container is responsible for scanning the locations specified in Section 6.2 and discovering the persistence.xml files and processing them. When the container finds a persistence.xml file, it processes the persistence unit definitions that it contains. {quote}
