Which grails plugin should I use for large file upload?

Question

which grails plugin should I use to upload large video files, like 20MB, 30MB, 100MB, I want progress bar also to be there, I have tried to use Super file upload plugin for this, but I think I am doing something wrong in it, it ain't working for me, should I go with this, or some other more easy to use plugin available out there, I have seen Jquery plugin too, but as I only have to add one video in one time, I think super file upload plugin will be good for me.

I have tried it, but getting error, please find below for the code.

Although for the error on the super file upload plugin:

in my GSP I have:

    <sfu:generateConfiguration fileSize="300" form="bookForm"  buttonWidth="104" buttonHeight="30"/>

<form class="form-horizontal" id="bookForm" name="saveVideoFile" action="saveVideoFile" onsubmit="return sfuSubmitForm(this);">
        <div class="control-group">
            <label class="control-label" for="inputEmail">Select Category</label>
            <div class="controls">

            <label class="control-label" for="inputPassword">Upload file</label>
        <div class="control-group">
            <div class="controls">
                 Choose file: 
                 <sfu:fileUploadControl></sfu:fileUploadControl>
                    <br/>
                    Progress bar: <sfu:fileUploadProgressBar/>
                    <br/>
            </div>
        </div>
          <input type="submit" value="Save">
    </form>

and then in the controller saveVideoFile action:

def saveVideoFile(){
    String uploadFilename = params.uploadedFileId
    println("params=${params}")

    String fileUploaded

    if ( uploadFilename ) { // get the full path name of the file from the temp directory
        def file = superFileUploadService.getTempUploadFile(uploadFilename)

        fileUploaded = fileUploadService.uploadFile( file, "newFile.jpg", "assets/uploadFile/" );
        println("fileUploaded=${fileUploaded}")

    }else{ // file was not uploaded by flash. User might have javascript off
        def fileStream = request.getFile('sfuFile'); // handle normal file upload as per grails docs
        fileUploaded = fileUploadService.uploadFile( fileStream, "newFile.jpg", "assets/uploadFile/" );
        render "Nothing to upload"
    }


}

and I have a function in the service for saving the file object:

 String uploadFile( File file, String name, String destinationDirectory ) {

        def serveletContext = ServletContextHolder.servletContext
        def storagePath = serveletContext.getRealPath( destinationDirectory )

        def storagePathDirectory = new File( storagePath )

        if( !storagePathDirectory.exists() ){
            println("creating directory ${storagePath}")
            if(storagePathDirectory.mkdirs()){
                println "SUCCESS"   
            }else{
                println "FAILED"
            }
        } 

        // Store file

        println("file In service=${file}")
        //def tempFile = file.getBytes()
        def tempFile = file
        if(!tempFile?.isEmpty()){
            tempFile.transferTo( new File("${storagePath}/${name}") )
            println("Saved File: ${storagePath}/${name}")
            return "${storagePath}/${name}" 
        }else{
            println "File: ${tempFile.inspect()} was empty"
            return null
        }
}

On save it is giving:

No signature of method: java.io.File.isEmpty() is applicable for argument types: () values: [] Possible solutions: identity(groovy.lang.Closure), isFile(), list(), dump(), inspect()

at line:

if(!tempFile?.isEmpty()){

on the service function.

and on printing tempFile variable, I am getting temp storage location path.

I know I am doing something wrong, any help will be useful.

Clearly there is no `isEmpty()` for `File`. Use `if(tempFile.size()){..}` when `tempFile` represents the jpg file. — dmahapatro, Jul 01 '13 at 15:40
but I have to upload video files, and even if I remove that condition then also I will error on the line: tempFile.transferTo( new File("${storagePath}/${name}") ) — Saurabh Dixit, Jul 01 '13 at 15:42
`def file = superFileUploadService.getTempUploadFile(uploadFilename)` returns an absolute file or a file location? — dmahapatro, Jul 01 '13 at 15:49
a file location something like c:\\templocation\789798798-7879-798798 — Saurabh Dixit, Jul 01 '13 at 15:50
Error msg on the console: No signature of method: java.io.File.isEmpty() is applicable for argument types: () values: [] Possible solutions: identity(groovy.lang.Closure), isFile(), list(), dump(), inspect() and file prints: c:\swf_temp\0000013f-9af0-40c4-8087-57dd4fe29610 — Saurabh Dixit, Jul 01 '13 at 15:54

Found the issue with my script, I was trying to invoke file as Multipartfile object, super file uploader gives a temporary location of the file on the disk, now by copy function it can be moved to specified directory:

If I change the conditional block in my service:

if(tempFile?.isFile()){
                String sourceFilePath = tempFile
                String destinationFilePath = "${storagePath}/${name}"
                (new AntBuilder()).copy(file: sourceFilePath, tofile: destinationFilePath)

                println("Saved File: ${storagePath}/${name}")
                return "${storagePath}/${name}" 
            }else{
                println "File: ${tempFile.inspect()} was empty"
                return null
            }

then it will be saved, I had to copy the file from the temporary location to actual directory. some more enhancements will be required, but for the above code it will work this way.

Not sure if it is the best way to do so, please feel free to update enhancements. Thanks — Saurabh Dixit, Jul 02 '13 at 06:18
