找不到mysql.jdbc.Driver - MySQL和JBoss的

我無法部署我與MySQL 5.5.11後端到JBoss 5的Web應用程序我得到這個錯誤：找不到mysql.jdbc.Driver - MySQL和JBoss的

引起：java.lang中.ClassNotFoundException：來自BaseClassLoader的com.mysql.jdbc.Driver @ 262b2310

我在下面粘貼了我的堆棧跟蹤。

這裏是我做了什麼......

我添加使用mysql-connector-java的5.1.14-bin.jar到{JBOSS_HOME}/lib目錄（即連接器應與MySQL 5.5.11的工作權利？）。我還將mysql-ds.xml添加到{JBOSS_HOME}/server/default/deploy。

<datasources> 
    <local-tx-datasource> 
     <jndi-name>MySqlDS</jndi-name> 
     <connection-url>jdbc:mysql://localhost:3306/my_libl_db</connection-url> 
     <driver-class>com.mysql.jdbc.Driver</driver-class> 
     <user-name>root</user-name> 
     <password>test</password> 
     <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name> 
    </local-tx-datasource> 
</datasources>

而且，我在web應用程序的classpath確信使用mysql-connector-java的5.1.14-bin.jar在我的lib文件夾中是。在JBoss管理控制檯的Resources/Datasources下，我確實看到MySqlDS狀態爲up。

我的項目（在Eclipse Indego發佈中）是一個帶有1個動態Web項目的企業應用程序項目。 Web應用程序有一個@Entity bean和一個@Stateless bean。 @Stateless被注入一個servlet（使用@EJB）。這裏是我的persistence.xml：

<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0"> 
    <persistence-unit name="ContactBookPersistUnit" transaction-type="JTA"> 
     <provider>org.hibernate.ejb.HibernatePersistence</provider> 
     <jta-data-source>java:/MySqlDS</jta-data-source> 
     <class>com.contact.model.Contact</class> 
     <properties> 
      <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/> 
      <property name="hibernate.hbm2ddl.auto" value="create-drop"/> 
     </properties> 
    </persistence-unit> 
</persistence>

我能做什麼錯？

文檔的此位說，你需要將JAR添加到/ lib目錄的文件在默認的服務器配置：

http://docs.jboss.org/jbossas/getting_started/v4/html/db.html

UPDATE：JBOSS 6，更新已被重寫，更模塊化。您必須將JBDC驅動程序添加到您的/ module目錄。

真棒！我的.ear現在已部署，我正在體驗新的Probs。謝謝您的幫助。 – AR3Y35

我複製了mysql-connector-java-5.0.7-bin.jar，但仍然無法正常工作。你能列出我已經複製到lib文件夾的jar文件的名稱 –

同樣的問題在這裏我將連接器jar複製到lib仍然有連接問題，任何解決方案？威廉斯？ – Ameya
