连接不会关，怎么弄

4 楼 mrsea2010 2012-08-03  

楼主，按照你的方法，点击联接，我都不能显示出页面，直接报404，这是为什么？

3 楼 xiaolicomehere 2011-08-17  

楼主：你好！
我用的是mysql数据库
按照您说的方法改了connection
但是出现了如下问题
ognlException while setting property "connection" on type " org.apache.struts2.views.jasperreports.JasperReportResult"
请问如何解决？

找了N多文章,没有对数据源使用connection的具体描述,都是datasource的..还是楼主的文章帮了大忙
