For your first test with the NullPointerException result. What's the log of the full startup? Could you create a unit test and create a JIRA issue so I could try to reproduce the issue?

Best regards,

I solved the problem, i was declaring the wrong way of @Beans in my @Configuration. If we choose no use xml, we should declare @Beans the another way:

<java>
package br.gov.mprj.mgp2;

import org.activiti.engine.*;
import org.activiti.engine.impl.history.HistoryLevel;
import org.activiti.spring.ProcessEngineFactoryBean;
import org.activiti.spring.SpringProcessEngineConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.SimpleDriverDataSource;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.JpaVendorAdapter;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import javax.persistence.EntityManagerFactory;
import javax.sql.DataSource;
import java.util.Properties;

@Configuration
@EnableTransactionManagement
public class ApplicationTestConfiguration {

    @Bean
    public DataSource dataSource() {
        SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
        dataSource.setUsername("sa");
        dataSource.setPassword("");
        dataSource.setUrl("jdbc:h2:mem:activiti;DB_CLOSE_DELAY=1000");
        dataSource.setDriverClass(org.h2.Driver.class);

        return dataSource;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean(DataSource dataSource) {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactoryBean.setDataSource(dataSource);
        entityManagerFactoryBean.setPackagesToScan("domain");
        JpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
        entityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter);
        entityManagerFactoryBean.setJpaProperties(hibernateProperties());

        return entityManagerFactoryBean;
    }

    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.setProperty("hibernate.show_sql", "true");
        properties.setProperty("hibernate.format_sql", "true");

        return properties;
    }

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

    @Bean
    public SpringProcessEngineConfiguration processEngineConfiguration(DataSource dataSource,
                                                                       PlatformTransactionManager transactionManager,
                                                                       EntityManagerFactory entityManagerFactory) {
        SpringProcessEngineConfiguration engineConfiguration = new SpringProcessEngineConfiguration();
        engineConfiguration.setDataSource(dataSource);
        engineConfiguration.setTransactionManager(transactionManager);
        engineConfiguration.setJpaEntityManagerFactory(entityManagerFactory);
        engineConfiguration.setHistory(HistoryLevel.FULL.getKey());
        engineConfiguration.setDatabaseSchemaUpdate(SpringProcessEngineConfiguration.DB_SCHEMA_UPDATE_CREATE_DROP);

        return engineConfiguration;
    }

    @Bean
    public ProcessEngine processEngine(SpringProcessEngineConfiguration springProcessEngineConfiguration) throws Exception {
        ProcessEngineFactoryBean processEngineFactoryBean = new ProcessEngineFactoryBean();
        processEngineFactoryBean.setProcessEngineConfiguration(springProcessEngineConfiguration);
        return processEngineFactoryBean.getObject();
    }

    @Bean
    public RepositoryService repositoryService(ProcessEngine processEngine) {
        return processEngine.getRepositoryService();
    }

    @Bean
    public RuntimeService runtimeService(ProcessEngine processEngine) {
        return processEngine.getRuntimeService();
    }

    @Bean
    public HistoryService historyService(ProcessEngine processEngine) {
        return processEngine.getHistoryService();
    }

    @Bean
    public ManagementService managementService(ProcessEngine processEngine) {
        return processEngine.getManagementService();
    }

    @Bean
    public IdentityService identityService(ProcessEngine processEngine) {
        return processEngine.getIdentityService();
    }

    @Bean
    public FormService formService(ProcessEngine processEngine) {
        return processEngine.getFormService();
    }

    @Bean
    public TaskService taskService(ProcessEngine processEngine) {
        return processEngine.getTaskService();
    }
}
</java>

I suggest you put on activiti docs a example with how to configure activiti without xml.

Thanks!
