使用Spring的Hibernate中的数据源连接错误

当我们试图使用hibernate和数据源（jndi查找）的spging映射连接数据库时，会出现此错误。 我在面板上附加了完整的堆栈跟踪，请帮助它创建我的应用程序暂停

从例外情况来看

Caused by: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null'

很明显，您没有为JDBC指定驱动程序类。

我同意@thekoju。如果没有正确指定驱动程序名，请确保输入与数据库供应商相匹配的正确类名。

数据源配置是正确的
Datasource Configuration is

<Context path="/amsurepremcalc" docBase="amsurepremcalc" crossContext="true" reloadable="true" debug="1">
<WatchedResource>WEB-INF/web.xml</WatchedResource>

<Resource name="inquizzitiveds" auth="Container" type="javax.sql.DataSource" factory="com.max.premcalc.utils.DataSource"

弹簧的配置是

${hibernate.dial}
${hibernate.show_sql}
${hibernate.hbm2ddl.auto}

请发布完整的堆栈跟踪，而不仅仅是前几行。发布Spring和Hibernate数据源的配置Spring配置和数据源配置？
