Hi, When I try to open the report using xls format, it comes up with this message - "The file you are trying to open "jasperservlet", is in a different format than specified by the file extension. Verify that the files is not corrupt and is from a trusted source before opening the file. Do you want to open the file now?" This appears only in Microsoft 2007 edition, 2003 opens fine. why do we get this message? IS there a setting to turn off this message? Thanks! Post edited by: vk01, at: 2008/02/11 15:25
