This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Hello all, I�m trying to put an applet to handle a form because the amount of date is huge and the page is very slow (and the data is growing and growing). At the beginning was ok I didn�t have so many records to manage but now the html-page is about 8000 lines long!! I don�t want to reload the page after a selection. This could be a solution: after a selection to send a query to the database and reload the page (instead of having all the data in the page) but it doesn�t look good to reload the page after any new selection (the user makes at least 5 selections before submitting the form). So now I am trying to move all the data to an applet, where I can handle all dynamically and without performance problems (beside all the nice view-features an applet has, comparing it with HTML). I don�t have problems with compatibility or such (applet, JVM, JRE, etc.) so no problems using applets. Any idea on how can I insert an applet in the struts model? Thank you!
I hate 'trial and error'<br />and I am doing it all the time
Struts is mainly for flow control and form processing. I don't think there's anything in Struts that's specific to applets. Just use the same HTML tag. Try breaking up the data and allow the user to page through it. There are a number of opportunities to improve performance if you do this. Have a look at this Java Blueprint for some ideas for improving performance when handling large lists.
thank you Junilu, I was already thinking in dividing the page in two (which is the maximum for my impacient users). Returning to applets: I could I pass the data from the Action to the applet and applet to Action?

I don't think so. Applets run on the client while the Action is running on the server. You might be able to get the two communicating via a component like HttpClient within your applet so that it can communicate with the server. Again, I would try to convince the user that it would be easier if you just break the data up into multiple pages.
