Ive attached code for a *.class file that runs a 2D heat problem and sets up everything to export a surface plot at the end but I do not know how to tell Eclipse to tell COMSOL to 'Click export' at the end. I have to open the *.class file with COMSOL, and click export. Any suggestions as to how to tell COMSOL to click 'export'?

Im starting the server before running in Eclipse (>COMSOL4.1>Client Server>COMSOL Multiphysics 4.1 Server). When I click 'run' in Eclipse, Im seeing that I connect but the plot does not appear on my desktop. At the end, it disconnects.

(To open file in COMSOL, remove lines 12 and 14)

Thanks
Alex
