在eclipse下用java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource定义data-source Tomcat无法启动的解决方法

分类: tomcat  |  作者: windowslover 相关  |  发布日期 : 2015-11-30  |  热度 : 1183°
在myeclipse下设置struts的struts-config.xml连接数据库:
<data-source key="mykey" type="org.apache.commons.dbcp.BasicDataSource">
  <set-property property="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
    .
    .
    .
 </data-source>
 
启动tomcat后,发现:

严重: Initializing application data source only

继续添加commons-pool-1.3.jar到lib中,重新启动tomcat,彻底搞定!!!
