我正在部署一个非常简单的helloworld风格的EJB应用程序。这样做我得到......

看起来我需要在某处添加一个include，我的代码非常简单...... 

package server;

import java.io.IOException;
import java.io.PrintWriter;

import javax.ejb.EJB;
import javax.persistence.EntityManagerFactory;
import javax.persistence.PersistenceUnit;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import model.MyUser;

/**
 * Servlet implementation class HelloServlet
 */
@WebServlet("/HelloServlet")
public class HelloServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;


    @EJB HelloBean bean;
    @PersistenceUnit
    EntityManagerFactory emF;
    /**
     * @see HttpServlet#HttpServlet()
     */
    public HelloServlet() {
        super();
        // TODO Auto-generated constructor stub
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter out = response.getWriter();
        out.print("<html><body>");
        MyUser user = (MyUser)emF.createEntityManager().createQuery("select * from  myuser").getResultList().get(0);
        out.println("Username = " + user.getName());
        out.print("</body></html>");
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
    }

}

Persistance.xml如下所示...... 

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/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">
    <persistence-unit name="HelloWorld">
        <jta-data-source>EjbMySql</jta-data-source>
        <class>model.MyUser</class>
    </persistence-unit>
</persistence>

modules / com / mysql / main / Modules.xml如下......

Standalone.xml具有以下条目...... 

<subsystem xmlns="urn:jboss:domain:datasources:1.0">

            <datasource jndi-name="java:jboss/datasources/EjbMySql" pool-name="EjbMySql" enabled="true" use-java-context="true">

        </drivers>
        </datasources>
        </subsystem>

在我的项目中，我在/WebContent/META-INF/services/mysql-connector-java-5.1.18-bin.jar中有MySQL jar

有没有人有任何想法？

谢谢！

编辑：试过...... 

<datasource jndi-name="java:jboss/datasources/EjbMySql" pool-name="EjbMySql" enabled="true" use-java-context="true">
                    <connection-url>jdbc:mysql://localhost:3306/ejbdb</connection-url>
                    <driver>com.mysql.jdbc.Driver</driver>
                    <security>
                        <user-name>root</user-name>
                        <password>root</password>
                    </security>

带来同样的错误。

答案 0 :(得分：6)

在<JBOSS_HOME>/standalone/configuration/standalone.xml中找到<subsystem xmlns="urn:jboss:domain:datasources:1.0">标记，并在<datasources>元素中添加以下内容：

<datasources>
    <datasource jndi-name="java:jboss/datasources/MysqlDS" pool-name="MysqlDS" enabled="true" use-java-context="true">
        <connection-url>jdbc:mysql://localhost:3306/DATABASE_NAME</connection-url>
        <driver>com.mysql</driver>
        <security>
            <user-name>USERNAME</user-name>
            <password>PASSWORD</password>
        </security>
    </datasource>
    <drivers>
        <driver name="com.mysql" module="com.mysql">
            <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
        </driver>
    </drivers>
</datasources>

以适当方式替换DATABASE_NAME，USERNAME和PASSWORD。

在<drivers>元素内添加以下内容：

<driver name="com.mysql" module="com.mysql">
    <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
</driver>

现在，转到<JBOSS_HOME>/modules并创建路径com/mysql/main将驱动程序的jar放在那里（例如mysql-connector-java-5.1.18-bin.jar）并创建文件{{1含有以下内容：

module.xml

这应该可以解决问题。

答案 1 :(得分：3)

我认为您需要将standalone.xml中的数据源与驱动程序模块关联，如下例所示（取自here：

     <datasources>
            <datasource jndi-name="java:jboss/datasources/ExampleDS" enabled="true" use-java-context="true" pool-name="H2DS">
                <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1</connection-url>
                <driver>h2</driver>
                <pool></pool>
                <security>
                    <user-name>sa</user-name>
                    <password>sa</password>
                </security>
                <validation></validation>
                <timeout></timeout>
                <statement></statement>
            </datasource>
            <drivers>
                <driver name="h2" module="com.h2database.h2">
                    <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
                </driver>
                <driver name="mysql" module="com.mysql.jdbc"> <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class> </driver>
            </drivers>
      </datasources>

此处数据源中的driver-element引用drivers-element中的驱动程序定义，该定义本身引用了您定义的模块和类。这就是我使用它的方式，它适用于JBoss 7.1。

答案 2 :(得分：0)

在JBoss 7中，为了创建数据源和安装JDBC驱动程序，更改了一些配置细节。在“定义数据源”和“安装JDBC驱动程序”部分中查看此迁移guide。

答案 3 :(得分：0)

是驱动程序的版本。更改新版本。相信，只有它！ 我将驱动程序mysql-connector-java-5.0.4-bin.jar更改为mysql-connector-java-5.1.25-bin.jar，然后问题解决了。
