Hi, Joseng: Thanks for you support, I need to do more study to understand your answer. I has a quick try as below http://localhost:8080/jasperserver/flow.html?_flowId=viewReportFlow&_flowId=viewReportFlow&ParentFolderUri=%2Freports%2FshinWorkFlow&reportUnit=%2Freports%2FshinWorkFlow%2FAttendApply&standAlone=true&decorate=no&j_username=jasperadmin&j_password=jasperadmin&ApplyNo=2021040004 it can work, but still has a problem, the [input control windows] will pop up with the param [ApplyNo=2021040004], user need push [apply], then the resault will show. How to skip the [input control] windows and show the report immediately??
