我正在使用Wildfly 9.X玩JTA交易 .

我能够得到UserTransaction

ut = (UserTransaction)new InitialContext().lookup("java:comp/UserTransaction");

然后我想用我的实体经理在我的dao类中使用它：ut.begin（）; em.joinTransaction（）; em.persist（NEWUSER）; ut.commit（）;

但我希望得到这个例外：

Caused by: org.h2.jdbc.JdbcSQLException: Table "MAP_USER" not found; SQL statement:
insert into MAP_USER (ADS_USER, BAD_PASSWORD_COUNT, COST_CENTRE, DB_PASSWORD, DB_USER, department, email, ENABLED_YN, EXPIRING_DATE, EXTERNAL_ID, EXTERNAL_LAST_SYNC, EXTERNAL_REPOSITORY , fax, FULL_NAME, LAST_BAD_PASSWORD, LAST_LOGIN, LAST_PASSWORD_CHANGE, password, PASSWORD_HISTORY, PROFILE_CODE, PROFILE_CODE_COMMENT, PROFILE_USER_YN, tel, USER_COMMENT, username) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

这是我的数据源：

                </driver>
            </drivers>

我已成功安装ojdbc6驱动程序作为wildfly模块 .

为什么误差会因h2而上升？它试图连接的数据源是什么？

EDITED

我通过以下代码行声明了我的实体管理器：

Context ctx = new InitialContext();
            EntityManagerFactory emfByJoss = (EntityManagerFactory)ctx.lookup(dao.getPersistenceJNDIUnitName());

EntityManager em = emfByJoss.createEntityManager(getJPAPropertiesForJboss(principal.getDataSource()));

private Properties getJPAPropertiesForJboss(String dataSourcePath) {  
    Properties properties = new Properties(); 
    properties.put ("hibernate.dialect", "org.hibernate.dialect.Oracle10gDialect");
    properties.put("javax.persistence.provider", "org.hibernate.jpa.HibernatePersistenceProvider"); 
    properties.put("javax.persistence.transactionType", "JTA");
    properties.put("javax.persistence.jtaDataSource", dataSourcePath); 
    return properties;  
}

数据源路径是我在wildfly中创建的数据源的jndi名称，而持久性xml是：

<persistence version="2.1"
xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="KAS-Mapping-AppHandled">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

        <class>com.my.MapUser</class>
        <properties>
            <!-- Bind entity manager factory to JNDI at java:jboss/myEntityManagerFactory -->
            <property name="hibernate.show_sql" value="true" />
            <property name="jboss.entity.manager.factory.jndi.name" value="java:jboss/EntityManagerFactory" />
        </properties>
    </persistence-unit>
</persistence>

我不得不这样做，因为数据源必须是动态的，并在运行时更改 .
