B4J Question Paths Directory Assets and other Mysteries.

[rgarnett1955]

Hi

I open up a map file viz:

    'Read the file and see whether it has any key:value pairs

    dirString = GetCanonicalPath(File.DirAssets) 'For experimentation only
    
    map = File.ReadMap(File.DirAssets, configFileArg)
    
    If map.Size = 0 Then
        Return
    End If

The dirString var returns as: W:\MyProgramFiles_W\PowerMonProgs\pmonDB_uServerJRDC\jRDC_sqLite\jRDCv2_sqLite\Objects\AssetsDir

But there is no such directory on my hard drive.

But the correct map data is returned by the "map = File.ReadMap(File.DirAssets, configFileArg)"

This map file is in: W:\MyProgramFiles_W\PowerMonProgs\pmonDB_uServerJRDC\jRDC_sqLite\jRDCv2_sqLite\Files

I don't understand this.

Does anyone know how all this Java directory/path stuff works? It's driving me nuts.

Also does the File.ReadMap command close the file and unlock it in terms of Windows file locking when the File.ReadMap is completed?

Best regards

Yes.

File.DirAssets is a virtual path. I don't see why it is driving you nuts. Just use File.DirAssets. Don't check if the file exists as you know it exists.

Hi Erel,

That's well and good,

But how do I back up data in virtual paths Java if I don't know where they are?

What are the rules for the "virtualisation" of the path. There must be some. It can't just be random.

I like to know what's going on that's why it's driving me nuts.

1. It has nothing to do with Java.
2. File.DirAssets is read-only. It will only include the files that you added in the IDE. No need to backup anything.

You can see the files inside the jar if you unpack it (in release mode).

Ahhh! Ask and you will find out

Thankyou Erel
