Hi Pioppogatto! Thank you very much, your advice help me well! this promblem solved! Thank you! And here is one more thing,after adding InputControls i pass pTeacherName parameter via url like:http://localhost:8080/jasperserver/flow.html?_flowId=viewReportFlow&standAlone=true&_flowId=viewReportFlow&ParentFolderUri=%2Freports%2FTest&reportUnit=%2Freports%2FTest%2FTeacherInfo&pTeacherName=ain web brower,JasperServer show a web page with a dialog allow me input value for pTeacherName,and in that dialog pTeacherName value is "a"(that has been evalued by url pTeacherName),and i press "apply" button it can query correct result,but notice the last part of url,pTeacherName=a, letter "a" is English letter (EN coding), when i pass pTeacherName with chinese letter (gb2312 coding),the value for pTeacherName in the dialog is a messy code, and i press "apply" button,it find nothing result,that's not correct,but i reinput the chinese letter in the dialog manully and press "apply" button is works fine! So,my second question is how can i pass chinese value (gb2312 coding) for pTeacherName via url and get correct result(without reinputting it manully)? or how can i config JasperServer to support gb2312 coding ? Thank you!
