环境eclipse3.1.1
myeclipse4.03
tomcat5
按照myeclipse的flash demo：Hibernate.swf和源程序BasicDB.zip一步一步进行操作，数据库换成ms sql server结果出现如下错误：
javax.servlet.ServletException: org.hibernate.HibernateException: Not able to obtain connection
org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:545)
