J2EE中 苦恼很久的问题!

大脑发晕啊 数据驱动是一定加进去了.
  <data-sources >
    <data-source key="sql" type="org.apache.commons.dbcp.BasicDataSource">
      <set-property property="password" value="sa" />
      <set-property property="minCount" value="2" />
      <set-property property="maxCount" value="10" />
      <set-property property="username" value="sa" />
      <set-property property="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver" />
      <set-property property="url" value="jdbc:microsoft:sqlserver://localhost:1433;databaseName=pubs" />
      <set-property property="readOnly" value="false" />
      <set-property property="autoCommit" value="false" />
    </data-source>
  </data-sources>这是 Struts-config.xml 数据源的配置信息.
