POJBoss 7 throwing Entity is not mapped when using @PersistenceContext
text
Body
copied!<p>I'm using Spring/JPA/Hibernate 3 in an application that <em>runs just fine in Tomcat 7</em> but fails in JBoss AS 7. I'm using the @PersistenceContext annotation to inject my entity manager in the DAOs but I get the <strong>"Entity is not mapped"</strong> exception when running a query. I DO NOT want JBoss to manage my persistence context and I'm using classpath scanning to construct my LocalContainerEntityManagerFactoryBean. I've tried disabling the jpa module from the JBoss standalone.xml and even adding a jboss-deployment-structure.xml with this content:</p> <pre><code><jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0"> <deployment> <exclusions> <module name="org.hibernate"/> </exclusions> </deployment> </jboss-deployment-structure> </code></pre> <p>It still doesn't work. What's the cause of this exception? Why does JBoss still try to manage my persistence context?</p> <p>P.S.: By default I get a strange PU definition (the PU root url is not my war!)</p> <pre><code>(MSC service thread 1-3) insurance-module 17:51:41.456 [MSC service thread 1-3] DEBUG org.hibernate.ejb.Ejb3Configuration - Processing PersistenceUnitInfo [ 17:51:41,456 INFO [stdout] (MSC service thread 1-3) name: default 17:51:41,456 INFO [stdout] (MSC service thread 1-3) persistence provider classname: null 17:51:41,456 INFO [stdout] (MSC service thread 1-3) classloader: ModuleClassLoader for Module "deployment.insurance-module-0.1-SNAPSHOT.war:main" from Service Module Loader 17:51:41,457 INFO [stdout] (MSC service thread 1-3) Temporary classloader: org.springframework.instrument.classloading.SimpleThrowawayClassLoader@13acaabd 17:51:41,457 INFO [stdout] (MSC service thread 1-3) excludeUnlistedClasses: true 17:51:41,457 INFO [stdout] (MSC service thread 1-3) JTA datasource: null 17:51:41,457 INFO [stdout] (MSC service thread 1-3) Non JTA datasource: com.mchange.v2.c3p0.ComboPooledDataSource [ acquireIncrement -> 3, acquireRetryAttempts -> 30, acquireRetryDelay -> 1000, autoCommitOnClose -> false, automaticTestTable -> null, breakAfterAcquireFailure -> false, checkoutTimeout -> 0, connectionCustomizerClassName -> null, connectionTesterClassName -> com.mchange.v2.c3p0.impl.DefaultConnectionTester, dataSourceName -> z8kfsx8l1ikdpo61c3bmxu|6b5638a, debugUnreturnedConnectionStackTraces -> false, description -> null, driverClass -> com.mysql.jdbc.Driver, factoryClassLocation -> null, forceIgnoreUnresolvedTransactions -> false, identityToken -> z8kfsx8l1ikdpo61c3bmxu|6b5638a, idleConnectionTestPeriod -> 60, initialPoolSize -> 3, jdbcUrl -> jdbc:mysql://localhost:3306/insurance, maxAdministrativeTaskTime -> 0, maxConnectionAge -> 0, maxIdleTime -> 60, maxIdleTimeExcessConnections -> 0, maxPoolSize -> 5, maxStatements -> 0, maxStatementsPerConnection -> 0, minPoolSize -> 1, numHelperThreads -> 3, numThreadsAwaitingCheckoutDefaultUser -> 0, preferredTestQuery -> select 1, properties -> {user=******, password=******}, propertyCycle -> 0, testConnectionOnCheckin -> false, testConnectionOnCheckout -> false, unreturnedConnectionTimeout -> 0, usesTraditionalReflectiveProxies -> false ] 17:51:41,457 INFO [stdout] (MSC service thread 1-3) Transaction type: RESOURCE_LOCAL 17:51:41,457 INFO [stdout] (MSC service thread 1-3) PU root URL: file:/home/mircea/jboss-as-7.0.2.Final/modules/sun/jdk/main/service-loader-resources/ 17:51:41,457 INFO [stdout] (MSC service thread 1-3) Shared Cache Mode: UNSPECIFIED 17:51:41,457 INFO [stdout] (MSC service thread 1-3) Validation Mode: AUTO 17:51:41,457 INFO [stdout] (MSC service thread 1-3) Jar files URLs [] 17:51:41,457 INFO [stdout] (MSC service thread 1-3) Managed classes names [] 17:51:41,457 INFO [stdout] (MSC service thread 1-3) Mapping files names [] 17:51:41,457 INFO [stdout] (MSC service thread 1-3) Properties [] 17:51:41,459 INFO [stdout] (MSC service thread 1-3) insurance-module 17:51:41.459 [MSC service thread 1-3] DEBUG org.hibernate.ejb.Ejb3Configuration - Detect class: true; detect hbm: true 17:51:41,462 INFO [stdout] (MSC service thread 1-3) insurance-module 17:51:41.462 [MSC service thread 1-3] DEBUG o.h.ejb.packaging.AbstractJarVisitor - Searching mapped entities in jar/par: file:/home/mircea/jboss-as-7.0.2.Final/modules/sun/jdk/main/service-loader-resources/ </code></pre>
