I am trying to render html file to pdf using rendering plugin, my controller method is,
def download() { response.contentType = 'application/pdf' response.setHeader("Content-disposition", "attachment; filename=\"download.pdf\"") def items = [] (101..105).each { number-> ByteArrayOutputStream bos = new ByteArrayOutputStream(); items << [number:number, bytes:bos.toByteArray()] } renderPdf (template:'download', model:[items:items]) } And my _download.gsp file is,
<%@ page contentType="text/html;charset=UTF-8" %> <html> <body> <g:each in="${items}" var="item"> <div>This is the barcode for the number: ${item.number}</div> <hr/> </g:each> </body> </html> I have added following dependencies in BuildConfig.groovy file
compile ":rendering:1.0.0" I received following stack-trace,
