Long Run Report

[stanley1610]

If one of my report will be run in a very long process (e.g. half an hour), it is not suitable for normal Web-based applications.

What should we do, using Servlet/JSP, to handle such case?

It seems difficult to use a batch job because the user's input is required.

The flow is like this:
1. User inputs some data and uploads some files
2. The server processes the input with ~1M records of data
3. The server outputs several reports (~ 20 kinds)

Is there any asynchronized web solution available for this case? Thanks.

Asumming the outputs are not to be sent back to the client, I don't see any problem using a JSP/Servlet: it will upload the files, initiate the process in the server, send a message back to the client saying the process has already started.

Cheers,
