Spring-Data-jpa with Spring XD

Question

I have my Configuration class with Beans as mentioned below

  @Bean(name = "entityManagerFactory")
  public LocalContainerEntityManagerFactoryBean  entityManagerFactory(@Qualifier("sqlServerDataSource") DataSource dataSource) {
      LocalContainerEntityManagerFactoryBean lef = new    LocalContainerEntityManagerFactoryBean();
      lef.setDataSource(dataSource);
      lef.setJpaVendorAdapter(jpaVendorAdapter());
      lef.setPackagesToScan("de.id.dih");
      return lef;
  }

  private JpaVendorAdapter jpaVendorAdapter() {
      HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
      hibernateJpaVendorAdapter.setShowSql(true);
      hibernateJpaVendorAdapter.setDatabase(Database.SQL_SERVER);
      hibernateJpaVendorAdapter.setDatabasePlatform("org.hibernate.dialect.SQLServer2008Dialect");
      return hibernateJpaVendorAdapter;
  }

  @Bean
  public PlatformTransactionManager   transactionManager(LocalContainerEntityManagerFactoryBean emf) {
      JpaTransactionManager transactionManager = new JpaTransactionManager();
      transactionManager.setEntityManagerFactory(emf.getObject());
      return transactionManager;
  } 

and Maven dependancies look like:

<dependency>
    <groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
    <!--<scope>provided</scope>-->
</dependency>

<dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>tomcat-jdbc</artifactId>
</dependency>

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.6</version>
</dependency>

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <version>4.0</version>
</dependency> 

And when I deploy my module in Spring XD, I get the following exception

ERROR DeploymentsPathChildrenCache-0 server.ContainerRegistrar - Exception deploying module

Is it possible to have Configuration class with above mentioned Beans in Spring XD environment ??

Any sooner help is greatly appreciated.

Thanks

Seems like a classloader issue. Make sure that your module lib/ directory does not contain any jars (same or different version) that are already in XD's global lib/ directory.

If you want to automate this and are ok with gradle, you could draw inspiration from https://github.com/pperalta/spring-xd-source-template build file (this is for a source module, but you can derive the same thing for other kind of module I bet)
