不能完成网页跳转

这个应该用到的是STRUTS框架，front对应struts的xml配置文件中package标签的name属性值, index对应的是action标签的name属性,index.do的写法表示执行index对应的类中默认方法（excute）

since i am not sure of what version of bw you are on this answer may be off base but ....i would recommend using business content for the 0pa_c01 data target (headcount and personnel actions). it has the necessary characteristics to be able to get the data you are looking to get. this cube comes with prestructured workbooks and queries.deb
