pdf export not working in grails 2.3.2

Question

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('&nbsp;',' ')           
            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:

and during pdf export it shows following error:

URI
/sAttend/report/summaryReport
Class
java.lang.NoSuchMethodError
Message
com.lowagie.text.pdf.PdfWriter.setRgbTransparencyBlending(Z)V

how can i solve this problem please help.

Answer 1

I tried both but it did not work so i added
build "com.lowagie:itext:2.1.7" in BuildConfig.groovy including

inherits("global") {
    excludes "itext"
}

and updated iText 2.0.8 to 2.1.7

Answer 2

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"
}
