求指教关于如何查询javabean问题
毕设指导老师给了个mysql连接数据库的例子 web三层框架考虑到jdbc对odbc的问题
我将例子中的驱动替换为在se下可以使用的sqljdbc4
环境：
jre 7
tomcat 6.0
随便写的helloworld.jsp可以运行
以下是错误日志

个人能看出来错误貌似有两个
一个是找不到eclipse生成或者是tomcat可以运行的文件 一开始的那个报警
另外一个是Failed to convert property value of type [java.lang.String] to required type [org.springframework.orm.jpa.vendor.Database] for property 'database'; nested exception is java.lang.IllegalArgumentException: No enum constant org.springframework.orm.jpa.vendor.Database.SQLserver
总感觉mysql和sqlserver2008 org里边不是一个bean的父类
以及两个unknown
at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)
请各位指教下错误出现在那里
创建bean的父类？数据库连接方式？还是xml或者三层框架配置？ bean database exception initialization --------------------编程问答-------------------- Caused by: org.springframework.beans.TypeMismatchException: Failed to convert property value of type [java.lang.String] to required type [org.springframework.orm.jpa.vendor.Database] for property 'database'; nested exception is java.lang.IllegalArgumentException: No enum constant org.springframework.orm.jpa.vendor.Database.SQLserver

类型转换 错误
Failed to convert property value of type [java.lang.String] to required type [org.springframework.orm.jpa.vendor.Database] --------------------编程问答--------------------
你看前边那些字
No enum constant org.springframework.orm.jpa.vendor.Database.SQLserver
类型准换错误是由于找不到转换类型的方式
ex:
xx.valueof(String)
不知道xx是integer还是什么造成的这个错误吧 类似的错误还有很多
补充：Java , Web 开发
