Camunda supports MyBatis only. So don’t add explicitly any Hibernate dependencies for transaction management. Might be in future release it could support Hibernate.

  1. Create a Bean called Datasource and inject oracle connection properties.
  2. create a DatasourceTransactionManager bean and inject the above Datasource bean.

Before process engine kick starts this 2 beans should be instantiated and configured. Add the below implementation any of the class which has @Configuration annotation or else create one.

@Bean(name = "dataSource")
  public DataSource dataSource() {   
    SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
    try {     
        dataSource.setDriver("");
        dataSource.setUrl("");
        dataSource.setUsername("");
        dataSource.setPassword("");
    } catch (InstantiationException | IllegalAccessException e) {
     //handle exception
    }
    return dataSource;
  }

  @Bean(name = "transactionManager")
  public DataSourceTransactionManager transactionManager() {    
    return new DataSourceTransactionManager(dataSource());
  }

Then you are good to go :slight_smile:
