我无法将我的Web应用程序与

MySQL 5.5.11后端部署到JBoss 5.我收到此错误：

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

我在下面粘贴了我的堆栈跟踪.

这就是我所做的……

我将mysql-connector-java-5.1.14-bin.jar添加到{JBOSS_HOME} / lib(该连接器应该与MySQL 5.5.11配合使用吗？).我还将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,我确保我的lib文件夹中的mysql-connector-java-5.1.14-bin.jar在我的web应用程序类路径中.在JBoss管理控制台的Resources / Datasources下,我确实看到状态为up的MySqlDS.

我的项目(在Eclipse Indego Release中)是一个带有1个动态Web项目的企业应用程序项目. Web应用程序有一个@Entity bean和一个@Stateless bean. @Stateless被注入一个servlet(使用@EJB).这是我的persistence.xml：

org.hibernate.ejb.HibernatePersistence

java:/MySqlDS

com.contact.model.Contact

我能做错什么？
