java - Access a dir in client machine -


i'm developing java web application (jsp-servlet) collage project.

if brief project..

i have read barcodes scanned documents , sort them according particular order , store in server , again show sorted output in jsp page.

  • to scan documents there's separate applet, , output of scanner applet temp_image folder. (i have start reading/decoding process right after applet process.)
  • to decode barcodes use api call zxing.

my issues are..

  • i have set-up application in number of machines so, if upload temp_image files server , decode there network traffic problem.
  • i have no sense of accessing dir in client machine server well
  • i've heard it's not recommended have several applets in same web-application.
  • at same time if use applet won't able store data in server too.

i'm kind stuck matter.. since i'm new java programming i'm not exposed new technologies too.

please suggest me new technology or efficient way this.

thanks in advance :)

web applications not allowed access client's resources (file system) directly.

to access (upload) barcodes client server machine need provide browse button, user can select saved barcode in png or jpeg format. can upload image server using multipart file upload.

if planning scan barcode directly client's camera, need include flash plugin, webcamjs example.
