1.Check the log to see whether the file path is correct. 2.I created 2 parameters SUBREPORT_DIR - (Default Value Experession) - "repo:/public/My_Domain/Reports/Reports/" SUBREPORT_EXT - (Default Value Experession) - ".jrxml" and used this in the "Subreport Expression" like $P{SUBREPORT_DIR}+"SampleReport"+$P{SUBREPORT_EXT}.It works. You can make the parameter to popup so that you can enter local values to view in iReports and the defult to be used in Jasper Server.Hope it helps.
