Question

Someone ask me to develop for him an Employee Leaves Application and he can carry it in his flash memory so that he can enter data at home, office or his private company.
I’ve chosen Java and SQLite cos they are free.
Can I create a Java standalone application that it can run in Flash memory when he plug it to a Windows XP platform ?
Thanks.

Yes. While the Java Runtime does write things into the registry such as “default JRE” .. you can still include a copy on the flash drive and call the java.exe command directly from the bin folder.

Here’s an example setup. Let’s say the flash drive is mapped to F:\. Your application is located at F:\YourApp.jar

You copy a Java install from Program Files and paste it to F:\Java

You then write a quick batch script to launch your program using the local java command. The batch file would look something like this:

@echo off
Java\bin\javaw.exe -cp .;YourApp.jar YourMainClass

You could name that start.bat or something similar, which should be obvious enough to your client.
