I have a question as in the subject line. I have developed a visualization that calls a program from command line, and it works fine on my computer. However, there are difficulties putting it in an applet, because I'd need to have my script running server-side.

After searching the forum, I found one solution which involves POSTing to a URL, which invokes a server-side php script, which does what needs to be done. That is one solution, and needs the following amendments in my visualization:

- implement POSTing to the URL

- put the visualization "on hold", and display some sort of progress bar or spinning indicator showing that it is "thinking", because there may be a considerable delay in getting the program finish server-side

- Continuously test whether the output file has been produced by the server-side script, and upon discovering it, unfreeze and proceed with the visualization.

Are there other solutions?

The reason I am asking this question again, is because developing this may need substantial time because exporting to applet, signing it and uploading to website to test an implementation is a VERY tedious task, especially if needed to do it repeatedly (which it probably will, because it is hard to implement this in one shot).

I would highly appreciate the opinions and experiences of the community. Thank you so much.
