This page is devoted to my old work on Java.
Applet which submitted here is a large and I hope interesting program.
The first purpose for what it was created, was to give the possibility for online users work with some reports by different way than in HTML.
Later it was changed, for what to execute SQL instructions such as UPRATE, INSERT, DELETE.
This applet provides a simple interface to the database, and made in untraditional way.
Firstly, there is wide used multithreads. You can start several reports and they will be load separately.
Secondly, it's what the applet doesn't use JDBC directly, instead of what, it connects to servlet on web server.
The servlet prepares the reports(compress and executes stored SQL procedures) and returns results to the applet.
Thus it's a three-level architecture.
You could look at it, but have in view of, that the size of applet is about 800K, and besides, you need Java Plugin >1.4 on your computer.
It can take some time, but installing is making automatically.
For the "Internet Explorer" don't forget to switch the usage of the Sun Java in the "Internet Options", on "Advanced" tab.
The materials submitted on this page can not be used in any way except of showing.
