Struts通过配置数据源连接数据库产生异常!java.lang.NoSuchMethodError

[benben525]

Struts-config.xml配置情况:使用DB2数据库 数据库名称为:wl
<data-sources>
<data-source key="db2" type="org.apache.commons.dbcp.BasicDataSource">
<set-property property="password" value="123" />
<set-property property="username" value="db2admin" />
<set-property property="driverClassName" value="COM.ibm.db2.jdbc.app.DB2Driver" />
<set-property property="url" value="jdbc:db2:wl" />
</data-source>
</data-sources>

Action-->Addaction中代码:
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request,
HttpServletResponse response){
javax.sql.DataSource datasource;
java.sql.Connection myConnection = null;
java.sql.Statement stmt=null;
//datasource=(javax.sql.DataSource)servlet.getServletContext().getAttribute("db2");
datasource = this.getDataSource(request,"db2");
myConnection=datasource.getConnection();
stmt=myConnection.createStatement();
}catch(Exception sqle){
System.out.println("在连接数据库的时候抛出的异常是:"+sqle.getStackTrace());
}

异常显示:
严重: Servlet.service() for servlet action threw exception
