Running jconc as an applet

jconc can be run as an applet, i.e. a program that runs within the environment of a web browser. For security reasons, an applet cannot communicate with the host computer (your computer), it cannot read or store data on it. Rather, it must store its data at a secure location on a remote web server.

The i-concrete web site has an integrated version of the jconc applet (called iconc, but it is the same program) that allows saving files from the applet. Anyone can open an account on the i-concrete web server and use jconc from there.

One enormous advantage of using an applet is that there is no need to install anything on your computer, except for the Java runtime environment, like the one freely available from Oracle.

As of mid-2017, there are significant restrictions on the use of Java applets. Most current browsers do not support Java applets anymore and those that still do (Internet Explorer, Safari and some versions of FireFox) do require additional configuration steps for Java applets to run. Please read our regularly updated Configuration for Java applets pages to learn how to configure your computer for running our Java applets.

When running jconc as an applet, all outputs normally sent to the command window are redirected to the Java console, which can be activated usually by right-clicking on the Java icon in the task bar. This is useful, for instance, to check for the convergence of the solution.

IMPORTANT: the “Messages” option of the “Listing” menu gives an instant access to the important messages also displayed in the Java console. Make sure to read these messages to check how your calculation has been executed.
