Ok, excuse me, i might have detailed more my problem. I execute my report from a servlet, and i set the content type to "application/pdf". Then, from my Jsp page i open a window that call to servlet and display the report in PDF format. I have installed Acrobat 7.0 and it works correctly, i can see my report, but when i try it in other machine that it has installed Acrobat 6.0 or less, it don't work, the report is blank, and it don't give me any exception. I don't know if i explain me better, my english isn't good. Thanks. Post edited by: pajarokillo, at: 2006/09/27 13:25
