You are giving exactly ZERO Information which could help. Start with providing these infos. The Code used for example.

I would first try to run it non-obfuscated so you know what '_vvvvvv5' is. Maybe some folder is write protected?

Here are the errors after compiled non-obfuscated :

abmapplication._addpage (java line: 41)

Compiled jar file was located in directory d:\data\cr\object.

If I ran this compiled jar directly from this directory, it run OK, but when I copied the contents of d:\data\cr\object to drive H, it gave those errors.

The list of drive H are :
1. compiled jar file
2. copymewithjar.needs file
3. keystore.jks
3. directory of www

That's what I done on Ubuntu server, and it ran OK, but not on Windows. Where did I missing here?

Please post the complete log file (use code tags or upload as a file). The java.io.File error looks like it is unable to read or write a file and maybe the logs before the error can show where it was in the code.

Found the problem !

Drive H is a RAMDisk, use for a temporary disk in Windows. When all files copied to a real disk, it ran OK.

So compiled java file can run from a RAMDisk?

I guess not. Log what File.DirApp returns. Maybe B4J returns something unexpected?

Correction, sorry, it seem that it was not RAMDisk problem!

Tested again on RAMDisk, made a dir H:\ABM, copied all files and www directory to this folder, run jar file from this folder, and it ran OK.

Copied again all files and www directory to a root disk on drive D (this is the real drive), same error raised again.

Seem that the compiled jar file can't run from root directory.

That could make sense. ABM will search if the B4J source code files are available to analyse, and those are located one level below (parent) where the jar is. If it is in the root, this call will fail.

So this is intentionally?
No problem, I will not put ABM's jar file in root directory then.
