I am using grails 2.3.2 and jasperreport 1.8.0 with iReport 5.5.0 everytime csv and excel export are working but pdf export is not working,I have controller code as:
def reportWithOutComma = params.summaryReportDataTable.split(",")
def inst = Institution.get(session.institutionid.toLong())
def result = [:]
result.data = []
for(int i = 0;i<reportWithOutComma.size();i+=7){
def spaceReplacedData = reportWithOutComma.toString().replace(' ',' ')
def name = reportWithOutComma[i].decodeHTML().toString()
def index1 = name.indexOf("(")
def stdNames = name.substring(0,index1)
result.data << [StudentName:stdNames,
TotalDays:reportWithOutComma[i+1].decodeHTML(),
Holidays:reportWithOutComma[i+2].decodeHTML(),
LeaveDays:reportWithOutComma[i+3].decodeHTML(),
AbsentDays:reportWithOutComma[i+4].decodeHTML(),
LateMins:reportWithOutComma[i+5].decodeHTML(),
EarlyMins:reportWithOutComma[i+6].decodeHTML()]
}
params.InstitutionName = inst.name
params._format = "PDF"
params._file = "summaryReport" // filename of xml file
def report = jasperService.buildReportDefinition(params, request.getLocale(),result)
generateReport(report)
}
where generateReport contains:
def generateReport = { reportDef ->
if (!reportDef.fileFormat.inline && !reportDef.parameters._inline) {
response.setHeader("Content-Disposition", "inline; filename=\"${reportDef.parameters._name ?: reportDef.name}.${reportDef.fileFormat.extension}\"");
response.setHeader("Content-Type", "${reportDef.fileFormat.mimeTyp}");
response.contentType = reportDef.fileFormat.mimeTyp
response.characterEncoding = "UTF-8"
response.outputStream << reportDef.contentStream.toByteArray()
} else {}
}
and i have xml file as created by iReport is:
<?xml version="1.0" encoding="UTF-8"?>

其他提示
If you run grails dependency-report you will probably see that there are 2 versions of itext in the report. The one that Grails uses to generate documentation is probably conflicting. Try and exclude it by modifying your BuildConfig to exlclude the one used by Grails:
inherits("global") {
excludes "itext"
}
