Error creating bean with name 'sqlMapClient' defined in class path resource [appli

我想用自己写的一个基于Servlet的struts2框架 加上 mybatis 加上 spring 加 oracle 做一个小型的货物信息管理 我在数据库中建了表，consumer 也有对应的实体类，想通过mybatis进行查询出结果和输入的结果校验，出现了错误，描述如下： 1.java.lang.reflect.InvocationTargetException 2.Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlMapClient' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse config resource: class path resource [sqlMapConfig.xml]; nested exception is com.ibatis.common.xml.NodeletException: Error parsing XML. Cause: java.lang.RuntimeException: Error parsing XPath '/sqlMapConfig/sqlMap'. Cause: com.ibatis.common.xml.NodeletException: Error parsing XML. Cause: org.xml.sax.SAXParseException: Document root element "sqlMap", must match DOCTYPE root "null". 我导入了ibatis.jar,log4j.jar,ojdbc14.jar,commons-logging.jar,spring aop,spring core,c3p0,spring.jar 我不知道哪里错了。
