Hi,

I’ve got a code that reads form a text file. (The data is coming from a parallel port every ten minutes, and is getting stored in the text file, every time a new data is read, it overwrites the previous data) this data from the text file is taken by the jsp and displayed onto a browser.

The code I have done, refreshes every 10minutes. The problem is, i don’t no how to save the previous data, so the user will...
