Write the Button And Create A link To this Controller Action In Your GSP like below.

<g:link class="btn btn-info btn-sm" 
      action="downloadMyFile" resource="${instance}" 
                           target="_blank">DOWNLOAD FILE</g:link>

            def file = new File("download/path/to/your/file")
            response.setContentType("application/pdf")
            response.setHeader("Content-disposition", "filename=${file.getName()}")
            response.outputStream << file.newInputStream()

             response.setHeader("Content-disposition", "filename=${file.getName()}")
             response.outputStream << file.newInputStream()  
        }

Note:

resource : You can pass Instance to your download action.

target="_blank" : Open/Download File In New Tab.

action : Action name that is defined in Controller.

How to view a doc/pdf file in grails application?

Assuming that you don't just want to link to some other file on your server (if you do, Rahul's answer is perfectly fine) then you may want to consider something like this in a controller:

def retrieveFile() {
    File fileToReturn = new File("${params.filePath}")
    String filename = "whatever your filename is"
    byteOutput = fileToReturn.readBytes()
    response.setHeader("Content-disposition", "attachment; filename=\"${filename}\"");
    outputStream << byteOutput
}

Then link to that (g.createLink or whatever) with the appropriate file path.

Grails: Render pdf from external location

If you're in grails 2.x, you can configure a target directory in Config.groovy

For instance

grails.datapath.userguides = "C:/Users/user1/userGuides/"

if you want to configure this depending the environment you can do like this :

development {
    grails.datapath.userguides = "C:/Users/user1/userGuides/"
}
test {
    grails.datapath.userguides = "C:/anotherDirectory/userGuides/"
}
production {
    grails.datapath.userguides = "/var/www/${appName}/userGuides/"
}

Then define a controller to access your files, for example a DocumentsController with this action

def downloadUserGuide()
{
    ... // code to get your entity file that you use in your example to do
    ... // file.getValue()

    String path = grailsApplication.config.grails.datapath.userguides
    String label = ... // If you want to display another file name

    render(contentType: "application/pdf", file: new File(path + file.getValue()), fileName: label)
}

Grails downloading pdf file from REST webservice endpoint

This is the adjusted code..but I am still getting the same result.

def generatePDF(){

 String body = documentContents.responseEntity.body
 ByteArrayOutputStream docStream = new ByteArrayOutputStream() 
 docStream.write(body.bytes) /* Write bytes into byte array*/
 response.setHeader(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=test.pdf")
 response.setContentType("application/pdf")
 response.setCharacterEncoding("UTF-8")
 response.contentLength = docStream.size()
 response.outputStream << docStream.toByteArray()
 response.outputStream.flush()
 response.outputStream.close()
}

Indicating in groovy to use the value of textfield named 'A ' at a different position int the same gsp

I used submitButton inside form tag.This is because the data in a text field will only be passed to the server if you submit a surrounding form (unless you use Javascript),and also as Igor Artamonov said link tag generates the link on server side,before user enters value into the text field.

Call controller in Ajax to download a file in Grails

You do not required the Ajax to download a file.

You can simply use window.location to download your file.

Example:

$("#exportAllSelectedData").click(function() {
    window.location="<g:createLink controller="mycontroller" action="exportPreferences" />"
});

If you try with Ajax, you will get(render) file text

Example:

$("#exportAllSelectedData").click(function() {
        $.ajax({
            type: "GET",
            url: "<g:createLink controller="demo" action="exportPreferences" />",
            success: function (data) {
                console.log(data);               
            }
        });
    });

Hope this will helps you.

How can i do a division operation in gsp page.

Try this:

${(odimatches.count / totalmatches.count)}

show custom name in printerqueue with ghostscript

the problem was fixed by displaying the commandline like so: var gsArguments = string.Format("-ghostscript \"{0}\"{1}{2}{3} -noquery -dPDFFitPage -printer \"{4}\" \"{5}\" \"{6}\"",
GhostScript.GetExecutablePath(),
colorSetting,
duplexSetting,
copiesSetting,
_printerRepository.Find(x => x.FirstOrDefault(y => y.Id == printJob.Printer)).PrinterName,
printJob.SourceXml,
outputfilename);

all the variables represent specific settings and in contrary of what the documantion on ghostscript says that one should use /Usersettings and then /Documentname i just put the variable inline with the rest and it displays the name set to display in the printerqueue

if i misunterstood the documentation feel free to correct me, i'm posting this answer to help anyone with the same problem as i did in the future.
