 i ever had this trouble,
when i develop program using ADF in linux,
in linux, all report that i build can be downloaded as PDF using method that i make in my JSPX program,
after i change my OS, it, can't be downloaded anymore,
the error log says :
"Can not find subreport in /home/reports"

try to check your parameter, if you use parameter subreport (not static), than should be a parameter named "SUBREPORT_DIR" in your report project,
click parameter "SUBREPORT_DIR", than on the properties, change the Default Value Expression,
Example, if you use windows, the default value expression should "D:\\project\\reports\\"
change it to where you place your report in linux, ex : "//home//project//reports//"

i hope it can help ypu solve your problem, :)
