Spring 4, Hibernate JPA JarInputStreamBasedArchiveDescriptor Error on Websphere 8.5.5

Question

I have a Spring MVC/Spring-Data-JPA (with Hibernate) application running perfectly on the Websphere 8.5.5 Liberty Profile. However, when I deploy to the full version of Websphere 8.5.5. I get the error pasted below.

My other beans naturally rely on the EntityManagerFactory, so this kills me. Have been googling all day to no avail.

• Environment: Websphere 8.5.5
• Spring Version: 4.0.4.RELEASE
• Hibernate EntityManager Version: 4.3.5
• IDE: IBM RAD (Version: 8.5.5) (Eclipse 3.6.3)

I'm taking an all-JavaConfig approach to Spring as well as JPA (i.e. I have no persistence.xml file.).

I found the following question, but it doesn't resolve my situation:

JPA entities as a shareable jar not working in a WAR file unde Tomcat 7.0.27

Any ideas?

Answer 1

Try the following configuration.

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages="com.mycompany.myapp.repository")
@ComponentScan(basePackages={"com.mycompany.myapp.service", "com.mycompany.myapp.domain", "com.mycompany.myapp.transformer"})
public class AppConfig {

    private static final Logger logger = LoggerFactory.getLogger(AppConfig.class);

    @Bean
    @Autowired
    public PlatformTransactionManager transactionManager(EntityManagerFactory emf){
        JpaTransactionManager txManager = new JpaTransactionManager();
        txManager.setEntityManagerFactory(emf);
        txManager.setDataSource(dataSource());
        return txManager;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(){
        LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
        //DATA SOURCE
        emf.setDataSource(dataSource());
        //JPA VENDOR ADAPTER
        logger.debug("About to create HibernateJpaVendorAdapter.");
        emf.setJpaVendorAdapter(jpaVendorAdapter()));
        //PACKAGES TO SCAN
        emf.setPackagesToScan("com.mycompany.myapp.domain", "com.mycompany.myapp.transformer.rule");
        //JPA PROPERTIES
        emf.setJpaProperties(jpaProperties());
        return emf;
    }

    public Properties jpaProperties() {
        Properties jpaProps = new Properties();
        jpaProps.put("hibernate.max_fetch_depth", 3);
        jpaProps.put("hibernate.jdbc_fetch_size", 50);
        jpaProps.put("hibernate.jdbc_batch_size", 10);
        jpaProps.put("hibernate.dynamic-update", "true");
        //https://hibernate.atlassian.net/browse/HHH-6962 TRYING TO AVOID HIBERNATE ERROR: HHH015010
        jpaProps.put("hibernate.exclude-unlisted-classes", "true");
        jpaProps.put("hibernate.archive.autodetection", "false");
        return jpaProps;

        adapter.setDatabasePlatform("org.hibernate.dialect.Oracle10gDialect");

    public DataSource dataSource(){
        final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
        dsLookup.setResourceRef(true);
        DataSource dataSource = dsLookup.getDataSource("jdbc/myapp");
        return dataSource;
    }

}
