Need help to make OpenYabs portable

On Win7 x64 I get the connection wizard prompt, then nothing. Running from the base app works fine.

Have you looked at the error log for the non-working version (in the %USERPROFILE%/Cache folder)?

I get the following:
Tue Mar 19 10:50:53 EST 2013:
Booting Derby version The Apache Software Foundation - Apache Derby - 10.8.2.2 - (1181258): instance a816c00e-013d-7fe9-ae41-00000073b6d8

Also note that setting the OpenOffice path as you are is not a good thing:
1) What happens if the user doesn't have OpenOffice Portable installed?
2) What happens if the user wants to use LibreOffice Portable, or a locally installed OOO or LO? You will overwrite a user-defined setting on every run.
3) Will referencing OOO (or LO) Portable's base executables like this cause that app to run non-portably?

I know next-to-nothing about Java so take this as you will, but from my perspective the problem may lie earlier than the empty derby.database.classpath.

Specifically I think it is either (or maybe both) of these lines that indicate the problem:
user.dir=P:\PortableApps\YabsPortable\App\Yabs
derby.system.home=null

To me user.dir should be the Data directory, not the program directory (unless it is a badly coded/named variable).

Is there maybe an environment variable (or two) that you are missing?

Or maybe even a verbose option you can pass to the base app to produce a similar log from a working copy for comparison?

Apologies if I am leading you off-track though. As I said I may be completely wrong having very little knowledge of Java apart from writing a (so far) barely functioning Android app.

Give me half an hour and I can check on 32 bit Win 7.

EDIT:

Doesn't work on 32bit Win 7 either - exact same error log, so it is something to do with Win 7 (and probably Vista) as opposed to 32 vs 64 bit architecture.

Am looking into a couple of things now, will report what (if anything) I find.

No need to specify JAVA_HOME, it is already created by the launcher (and isn't actually used by Yabs from what I can see).

A few things I can verify:
1. Yabs runs successfully from jPortable when run from the command line - so jPortable vs local Java isn't the issue.
2. All environment variables being passed from Yabs.exe to javaw.exe match those passed from YabsPortable.exe to javaw.exe - except USERPROFILE (which you are setting in the launcher.ini) and TEMP & TMP (which is set by the PortableApps Launcher) - which I have manually overridden to be the same without success.

I've also tried using different permutations of the command line options being passed from Yabs.exe to javaw.exe, all to no avail.

There is something going on in Yabs.exe that we just aren't seeing (even ProcessExplorer couldn't show me any differences than what I listed above).

Unless someone else can shed some light on the problem, my ideas are drained, sorry.

Xp so i would try the combatibility function of windows when a program doesn't work

I've narrowed it down - it is something to do with the USERPROFILE redirect. It works fine from Yabs.exe or javaw.exe using a [DirectoriesMove] on the profile dir instead of the USERPROFILE redirect.

You'll just have to do it that way I think.

It is not (directly) a Windows version issue.

Both the executable and the jar work just fine under Win7 when the app's data is placed in the default location, it only breaks when we redirect the USERPROFILE env var - which means either there is a command line switch we are missing or Yabs has a bug when USERPROFILE is redirected.

This isn't an issue that setting compatibility can fix.
