I do similar things.
First there is a snippet using the bind functionality.
var image : FileParamHolder = _
bind("widget", xhtml,
"image" -> fileUpload(image = _)
}
Now write out:
val wbos : ByteArrayOutputStream = build(image)
val fout = new File(outputFilename)
if (fout.exists()) {
Log.error("Tried to overwrite existing file")
return "Error: Filename already exists"
}
val foStream = new FileOutputStream(fout)
foStream.write(wbos.toByteArray())
foStream.close()
def build(image : FileParamHolder) : ByteArrayOutputStream = {
val bout = new ByteArrayOutputStream()
val zipout : ZipOutputStream = new ZipOutputStream(bout)
zipout.setMethod(ZipOutputStream.DEFLATED);
zipout.setLevel(Deflater.DEFAULT_COMPRESSION);
writeImage(zos, image)
}
private def writeImage(zos: ZipOutputStream,
image:FileParamHolder):Unit = {
if (image.fileName == "") {
Log.info("Provided image file is null")
return
}
if (image.fileName.lastIndexOf("\\") != -1) //this is needed if
upload is from a windows system
zos.putNextEntry(new ZipEntry("res/" + image.fileName.substring
(image.fileName.lastIndexOf("\\")+1)))
else
zos.putNextEntry(new ZipEntry("res/" + image.fileName))
zos.write(image.file, 0, image.file.length) //make here a loop on
very large files
zos.closeEntry()
}
Cheers
