What did you mean with functions ? Are these client side parser-functions
for csv data ?
But google charts can at the moment not parse csv data directly on the
client side ?
On Server-Side is use Spring MVC.. On my Website someone can upload a csv
as a MultiPart Upload to my server or directly to my website.
on the Server-Side there is a Rest-Service that gets the Multipart csv file:
@RequestMapping(value="/upload", method=RequestMethod.POST)
@ResponseStatus(value=HttpStatus.NO_CONTENT)
public @ResponseBody String
handleFileUpload(@RequestParam(value="name", required=false) String name,
@RequestParam(value="file1") MultipartFile file){
//Reads the CSV File
InputStream inputStream = file.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new
InputStreamReader(inputStream));
}
Is it now possible that i can convert the PartFile with the csv to a
DataTable ?
On the Client Side i have the same csv part file.. i can read it with a
FileReader();
Best regards
