Yes, it does. There's a file called JAlbum.jar which contains the app, and |
| 65 |
it's location is visible to the script. There's no path so I'm assuming the |
| 66 |
file is in the current directory. |
| 67 |
|
| 68 |
A .jar is just a special kind of zip file (much like OOo files are). What's |
| 69 |
inside it? |
| 70 |
|
| 71 |
p.s. I don't know how familiar you are with Java's start-up process and how it |
| 72 |
finds things and how you specify things to find. It's somewhat unusual and |
| 73 |
many traps exist for the unwary :-) |
