SDN null on DelegatingGraphDatabase.getIndex(DelegatingGraphDa tabase.java:131)

[bytor99999]

I have seen a couple threads on this.

We are using Spring 3.1.3

We are also configuring everything in Java Based Configuration. @Configuration.

Caused by: java.lang.NullPointerException: null

Here is our configuration class

@ComponentScan(useDefaultFilters = false,
    basePackages = {"com.blah.account"},
    includeFilters = {
        @ComponentScan.Filter(type = FilterType.ANNOTATION, value = AccountServerApp.class)
    },
    excludeFilters = {
        @ComponentScan.Filter(type = FilterType.ANNOTATION, value = Controller.class)
    }
)
@ImportResource(value = {"classpath*:META-INF/spring/applicationContext-security-account.xml," +
    "classpath*:META-INF/spring/applicationContext-graph.xml"})
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = {"com.blah.account.repository.jpa"})
@EnableNeo4jRepositories(basePackages = {"com.blah.account.repository.neo4j"})
@PropertySource({"classpath:META-INF/spring/neo4j.properties"})
public class BlahApplicationConfiguration extends Neo4jConfiguration {

  @Autowired
  Environment env;

  @Bean
  public PersistenceAnnotationBeanPostProcessor persistenceTranslator() {
    return new PersistenceAnnotationBeanPostProcessor();
  }

  @Bean
  public DataSource dataSource() {
    EmbeddedDatabaseBuilder embeddedDatabaseBuilder = new EmbeddedDatabaseBuilder();
    embeddedDatabaseBuilder.addScript("classpath:META-INF/sqlscripts/create-account-tables.sql");
    return embeddedDatabaseBuilder.build();
  }

  @Bean public EntityManagerFactory entityManagerFactory() {
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    vendorAdapter.setDatabase(Database.HSQL);
    vendorAdapter.setGenerateDdl(true);

    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
    factory.setJpaVendorAdapter(vendorAdapter);
    factory.setPackagesToScan("com.hdpoker.account");
    factory.setDataSource(dataSource());

    factory.afterPropertiesSet();

    return factory.getObject();
  }

  @Bean public JpaDialect jpaDialect() {
    return new HibernateJpaDialect();
  }

  @Bean public PlatformTransactionManager transactionManager() {
    JpaTransactionManager txManager = new JpaTransactionManager();
    txManager.setEntityManagerFactory(entityManagerFactory());
    return txManager;
  }

  @Bean(destroyMethod = "shutdown")
  public GraphDatabaseService graphDatabaseService() {
    return new EmbeddedGraphDatabase(env.getProperty("neo4j.location"));
  }
}

Thanks

Again, I just gave up and went back to using xml for all that configuration and now it works.
