[求助]Struts连接数据库出错!

我的struts-config.xml是这样配置的!
<data-sources >
<data-source key="DATA_SOURCE" type="org.apache.struts.util.GenericDataSource">
<set-property property="minCount" value="" />
<set-property property="password" value="sa" />
<set-property property="maxCount" value="" />
<set-property property="user" value="sa" />
<set-property property="driverClass" value="com.microsoft.jdbc.sqlserver.SQLServerDriver" />
<set-property property="description" value="datasource for strutstest" />
<set-property property="url" value="jdbc:microsoft:sqlserver://F9BBE496C1104BD:1433;DatabaseName=LoginTest" />
<set-property property="autoCommit" value="false" />
<set-property property="readOnly" value="false" />
<set-property property="loginTimeout" value="" />
</data-source>
在Action中是这样连接的:
ServletContext context = this.servlet.getServletContext();

DataSource ds=(DataSource)context.getAttribute("DATA_SOURCE");
Connection conn=null;
Statement stmt=null;
ResultSet rs=null;
try {
conn=ds.getConnection();
stmt=conn.createStatement();
String sql="select * from usertable";
rs=stmt.executeQuery(sql);
但服务器提示出错!
