Hi All I am trying to upload the file of 1kb to 250MB. I had developed 2 applications 1>In Struts framework (one application) 2> and using servlets and JSP (second application)
I am using second application (using servlets and JSP ) when i am trying to upload locally on my machine it is working very fine and able to upload as much as i can so for testing i have to upload MAX till 250MB(because it is client requirement)
All these experiments are on the development server and External IP (using internet) In my application i am splitting the file say example: I am tring to upload 100Mb of file step 1> on the server side i am splitting the file of 100Mb in to 1Mb and saving in the Temporary folder step 2> I am joining the splitted files and then again joining to the orignal file (at the time of upload ) to the destination location step 3 > Deleting the temporay folder after the joining is done
So These are the results on Development Server (L.A.N) local area network For --->>13Mb -------->>(Time Taken) 3 minutes For --->>25Mb -------->>(Time Taken) 6 minutes For --->>56Mb -------->>(Time Taken) 11 minutes For --->>100Mb -------->>(Time Taken) 18 minutes For --->>150Mb -------->>(Time Taken) 30 minutes For --->>250Mb -------->>(Time Taken) 58 minutes
Similiarly These are the results on External IP (through internet) For --->>20Mb -------->>(Time Taken) 5 minutes For --->>56Mb -------->>(Time Taken) 11 minutes For --->>78Mb -------->>(Time Taken) 20 minutes
after that if i am tring to upload more than this i am unable to upload and getting this exception at the server LOG
1>org.apache.commons.fileupload.FileUploadException: Processing of multipart/form-data request failed. Stream ended unexpectedly
2>org.apache.commons.fileupload.FileUploadException: Processing of multipart/form-data request failed. Connection reset
Can any one help me how to make this programm efficient and error free i cannot use FTP because i have to create a port which is not permitted by the client can any one help me out with the execellent solution
Can you explain, in a little more detail how you are doing these things?
