## Java Demo for Resumable.js

This sample might be outdated, note that resumable.js was renamed to flow.js.

This is a resumable.js demo for people who use java-servlet in server side.

`resumable.js.upload.UploadServlet` is the servlet. 

###Upload chunks

UploadServlet accepts Resumable.js Upload with 'octet' type, gets parameters from url like 

```
http://localhost:8080/test/upload?resumableChunkNumber=21&resumableChunkSize=1048576&resumableCurrentChunkSize=1048576&resumableTotalSize=28052543&resumableIdentifier=28052543-wampserver22e-php5313-httpd2222-mysql5524-32bexe&resumableFilename=wampserver2.2e-php5.3.13-httpd2.2.22-mysql5.5.24-32b.exe&resumableRelativePath=wampserver2.2e-php5.3.13-httpd2.2.22-mysql5.5.24-32b.exe
```

and gets chunk-data from http-body.

Besides, UploadServlet uses RandomAccessFile to speed up File-Upload progress, which avoids merging chunk-files at last.


###testChunks

UploadServlet supports Resumable.js's `testChunks` feature, which makes file upload resumable.


###Resumable.js options

UploadServlet only supports 'octet' upload, so make sure method in your resumable options  is 'octet'.

    var r = new Resumable({
                target:'/test/upload',
                chunkSize:1*1024*1024,
                simultaneousUploads:4,
                testChunks: true,
                throttleProgressCallbacks:1,
                method: "octet"
              });
