Java Applet, few question

Question

Hi,

i've got a few questions about applets in java.

Let's say that my app is Desktop application using Lucene, database is quite big (2GB, more than 2K elements), and search query is complicated too. I want to make a applet application using source code of my desktop app. And i want to know:

1. How heavy could i make applet? Is 7 MB to much ?
2. How fast can i make it? (Let's say 2 sec search + display results, with server on the same machine, 3GB RAM, 2.5GHz)
3. What with select text with mouse + ctrl+c, i have heard that it is quite hard to accomplished using Swing.
4. Is there any good software to black box GUI testing ?
5. What with OS ? Do i have to change something in app so it can work in Mac OS, Linux, Windows ?
6. What with Browsers ? Are they any problems with IE or any other ? Or is it solution that works fine everywhere?

Thx for help! Lukasz

How heavy could i make applet? Is 7 MB to much ?

7MB is not unusual for an applet nowadays.

What with select text with mouse + ctrl+c, i have heard that it is quite hard to accomplished using Swing.

No, that is very easy using Swing. Create a JTextArea and it will be selectable with the mouse (and Ctrl-C will copy to the clipboard by default.) You do not automatically get a pop-up menu when you right-click however. You will have to add that yourself if you need it.

What with OS ? Do i have to change something in app so it can work in Mac OS, Linux, Windows ? What with Browsers ? Are they any problems with IE or any other ? Or is it solution that works fine everywhere?

Provided the right version of the Java plug-in is installed, it should work fine everywhere.
