环境运行一直没有问题，不过以前用的驱动不支持JDK1.6所以 下载了最新的驱动程序sqljdbc_4.0 用了其中的 sqljdbc4.jar
因为数据库是windows验证所以WEB-INF\lib 下面也放了sqljdbc_auth.dll 文件
applicationContext.mxl配置文件如下
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"></property>
<property name="jdbcUrl" value="jdbc:sqlserver://192.168.100.56:1433;DatabaseName=RESEARCH;integratedSecurity=true;"></property>
<property name="user" value=""></property>
<property name="password" value=""></property>
<property name="acquireRetryAttempts" value="1"></property>
<property name="idleConnectionTestPeriod" value="100"></property> <!-- seconds -->
<property name="maxPoolSize" value="15"></property>
<property name="minPoolSize" value="5"></property>
<!--JDBC的标准参数，用以控制数据源内加载的PreparedStatements数量。但由于预缓存的statements
属于单个connection而不是整个连接池。所以设置这个参数需要考虑到多方面的因素。
如果maxStatements与maxStatementsPerConnection均为0，则缓存被关闭。Default: 0-->
<property name="maxStatements" value="5"></property>
<!--maxStatementsPerConnection定义了连接池内单个连接所拥有的最大缓存statements数。Default: 0>
<property name="maxStatementsPerConnection"></property-->
</bean>
启动tomcat时候报如下错误信息

实在从日志中看不到什么有价值信息，所以还劳烦各位帮忙看看。
