unix

grails.plugin.wkhtmltox.binary = "/usr/bin/wkhtmltopdf"

also add the pdf mime type to Config.groovy

    .....
   pdf:         'application/x-pdf'
]

Usage

to stream the content of an controller-action as pdf just call: /context/some/someAction.pdf

class SomerController {
    def someAction = {
        def someInstance = SomeDomainObject.get(params.id)

        render( filename:"File ${someInstance.id}.pdf",
                view:"/some/someGspTemplate",
                model:[someInstance:someInstance],
                header:"/pdf/someHeader",
                footer:"/pdf/someFooter",
                marginLeft:20,
                marginTop:35,
                marginBottom:20,
                marginRight:20,
                headerSpacing:10,
        )
    }
}

Or create binary pdf data and use them for any other purpose

class SomeService implements Serializable {

        def byte[] pdfData = wkhtmltoxService.makePdf(
                view: "/pdf/someGspTemplate",
                model: [someInstance: someInstance],
                header: "/pdf/someHeader",
                footer: "/pdf/someFooter",
                marginLeft: 20,
                marginTop: 35,
                marginBottom: 20,
                marginRight: 20,
                headerSpacing: 10,
        )


        // DO Something e.g. send as mail
        //sendAsynchronousMail {
        //    multipart true
        //    to "mail@mail.de"
        //    subject "see PDF Attachment";
        //    attachBytes "PDF Attachment.pdf", "application/x-pdf", pdfData
        //    body "see my pdf attachment"
        //}
    }
}
