我無法將我的Web應用程序與

MySQL 5.5.11后端部署到JBoss 5.我收到此錯誤：

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

我在下面粘貼了我的堆棧跟蹤.

這就是我所做的……

我將mysql-connector-java-5.1.14-bin.jar添加到{JBOSS_HOME} / lib(該連接器應該與MySQL 5.5.11配合使用嗎？).我還將mysql-ds.xml添加到{JBOSS_HOME} / server / default / deploy.

MySqlDS

jdbc:mysql://localhost:3306/my_libl_db

com.mysql.jdbc.Driver

root

test

org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter

另外,我確保我的lib文件夾中的mysql-connector-java-5.1.14-bin.jar在我的web應用程序類路徑中.在JBoss管理控制臺的Resources / Datasources下,我確實看到狀態為up的MySqlDS.

我的項目(在Eclipse Indego Release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).這是我的persistence.xml：

org.hibernate.ejb.HibernatePersistence

java:/MySqlDS

com.contact.model.Contact

我能做錯什么？
