無法獲取數據源。不能在JBoss 5.1上使用JPA EntityManager（EclipseLink）

Question

我在JPA（EclipseLink）在JBoss服務器上工作時面臨很多困難。我通常使用Tomcat和它很簡單......

1. 我複製的mysql-ds.xml中從/jboss-5.1.0.GA/docs/examples/jca到/jboss-5.1.0.GA/服務器/默認/部署/然後我配置它。

的mysql-ds.xml文件：

<?xml version="1.0" encoding="UTF-8"?> 
<datasources> 
    <local-tx-datasource> 
    <jndi-name>EDeliveryUnit</jndi-name> 
    <connection-url>jdbc:mysql://localhost:3306/edelivery_db</connection-url> 
    <driver-class>com.mysql.jdbc.Driver</driver-class> 
    <user-name>root</user-name> 
    <password>root</password> 
    <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name> 
    <check-valid-connection-sql>SELECT * FROM systemuser</check-valid-connection-sql> 
    <metadata> 
     <type-mapping>mySQL</type-mapping> 
    </metadata> 
    </local-tx-datasource> 
</datasources> 

1. 然後我在WebApplication的配置persistence.xml中。

的persistence.xml：

<?xml version="1.0" encoding="UTF-8" ?> 
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" 
version="2.0" xmlns="http://java.sun.com/xml/ns/persistence"> 
<persistence-unit name="edeliveryPU" 
    transaction-type="RESOURCE_LOCAL"> 
    <jta-data-source>jdbc/EDeliveryUnit</jta-data-source> 
    <non-jta-data-source>jdbc/EDeliveryUnit</non-jta-data-source> 
    <class>pt.inov.spocs.board.server.model.entity.SystemUser</class> 
    <class>pt.inov.spocs.board.server.model.entity.UserSession</class> 
    <properties> 
     <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" /> 
     <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/edelivery_db" /> 
     <property name="javax.persistence.jdbc.user" value="root" /> 
     <property name="javax.persistence.jdbc.password" value="root" /> 
     <property name="eclipselink.jdbc.batch-writing" value="JDBC" /> 
     <property name="eclipselink.ddl-generation" value="drop-and-create-tables" /> 
    </properties> 
</persistence-unit> 

結局我實例化的EntityManager：

private EntityManagerFactory emf; 
private EntityManager em; 

public Controller() { 
    System.out.println("Begin.."); 

    emf = Persistence.createEntityManagerFactory("edeliveryPU"); 
    em = emf.createEntityManager(); 

    user = em.find(SystemUser.class, new Long(1)); 
    System.out.println("Username: " + user.getUsername() + " | pass: " 
      + user.getPassword()); 
} 

當我部署我得到了這些錯誤在我的JBoss：

我嘗試了很多不同的方式，但我不能把這些工作。

任何人都可以幫助我嗎？

Answer 1

我找到了解決方案。

的JBoss迫使我們定義一個非JTA數據源，如果我們不希望使用交易或JTA數據源，如果你想使用它 ..

無論是不管我們是否想要使用事務，問題在於大多數信息提示我們要用jdbc/JNDI-NAME指定這些信息，當我們想要使用的是java：/ JNDI-NAME。

總之，如果你想使用的EclipseLink JPA與JBoss，而不是數據源，你需要確保你指定：

• transaction-type="RESOURCE_LOCAL"
• <non-jta-data-source>java:/JNDI-NAME</non-jta-data-source>或<jta-data-source>java:/JNDI-NAME</jta-data-source>

這裏是我的持久性的修正。xml：

<persistence-unit name="persistenceSamplePU" transaction-type="RESOURCE_LOCAL">  
    <non-jta-data-source>java:/EDeliveryUnit</non-jta-data-source> 

    <!-- Entities must be specified for EclipseLink weaving --> 
    <class>pt.inov.spocs.board.server.model.entity.SystemUser</class> 
    <class>pt.inov.spocs.board.server.model.entity.UserSession</class> 

    <properties> 
     <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" /> 
     <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/edelivery_db" /> 
     <property name="javax.persistence.jdbc.user" value="root" /> 
     <property name="javax.persistence.jdbc.password" value="root" /> 
    </properties> 
</persistence-unit> 

謝謝你的寶貴幫助@Chris。

您在指定「javax.persistence.jdbc.x」屬性，它們不會與數據源混合使用。你應該指定要使用的數據源，或JDBC連接url等，但不能同時使用。你想使用JTA嗎？還有一個警告，說明您正在使用transaction-type =「resource-local」並定義了JTA數據源 - 您需要爲要使用的JTA數據源指定「JTA」事務類型，並且將需要它，以便它可以掛鉤到JBoss事務管理器。數據源查找也可能需要設置目標服務器。
