[求助]hibernate错误：为什么找不到类？
我用的sql server 2005的数据库，用了ssh框架，hibernate的配置文件集成在applicationContext.xml里面，
exception
javax.servlet.ServletException: Hibernate operation: Cannot open connection; uncategorized SQLException for SQL [???]; SQL state [null]; error code [0]; Cannot load JDBC driver class 'com.microsoft.sqlserver.jdbc'; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class 'com.microsoft.sqlserver.jdbc'
org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:523)
