thanks for hozawa's answer. i have make clear the cause of the problem . it is that: the report that has problems was created in ireport ,it was edited in jasper studio. so ,it has problems when published on the server. when i created a new report in the jasper studio, and re-edit the content ,it can be published on the server successfully. i have also noticed that when you want veiw the report on the server , the report must have a datasource and use at least one field from the datasource.

in the jaspersoft studio's preview viewer,the report is mormal,but when it is published on the server, it becomes blank page,why?
