Question

I am developing for Blackberry usign phonegap and I need to copy all my app files to a writable location (I assume the app file location is red only).

Setting up the plugin to do this is easy enough using Java, however the problem I am having is finding the location of these files specific to my app so that I can copy and move them.

From previous reseaerch it seems that Class.getResourceAsStream would work e.g.

getClass().getResourceAsStream("/index.html"); 

However do not userstand how this can be specific to my app.

Thanks,

BlackBerry application file is packaged as *.cod file. It is kinda modified java *.jar file with hierarchical structure (folders, packages inside of the archive).

When you run getClass().getResourceAsStream("/index.html"); you get index.html file from the root package of your *.cod file. If there’s a file attached upon compilation process, then you will get it, otherwise the operation fails.

As you want to use a writable media, then consider FileConnections API of the RIM SDK.

cod files are stored to a special location (not the filesystem). But you will need to deal with the filesystem if you want to write files to the device memory or memory card.
