Application will launch in console, but not via VNC from menu, but will from VNC/shel

I have a problem which I'm hoping someone can help point me in the right direction to solve.

I am running Debian 6, with Fluxbox, XRDP, within a vmware machine.

I have customized the Fluxbox menu to launch the Android AVD Manager and SDK Manager.

[exec] (AVD Mgr) {/home/devdroid/android-sdk-linux/tools/android avd} <>
[exec] (SDK Mgr) {/home/devdroid/android-sdk-linux/tools/android sdk} <>

When I access the machine via the console, these links work beautifully and open the proper application.

When I access the machine via RDP using XRDP (VNC backend) and I click on these links, nothing happens. Yet if I take the same exact command within the XRDP session, and paste it into a terminal window in the same session, it runs properly without an issue. As a result its not an issue generically with the application I'm running. I can also run any other application within the menu without an issue (e.g. Firefox, rox-filer, Eclipse), so it appears to not be something generically with the menu over XRDP.

For the life of me, I can't think what would be different between launching a program from a menu, or via command shell in the same session, or for that mater where I'd look to find the logs/errors I need to troubleshoot.

As a result I have two questions:
1) Do you have any idea what is going on and why this doesn't work?
2) If not, do you have any idea what logs I can lookout to find information as to why things aren't launching, or how to turn on logging that will give me this info?

Thanks for your help!

Looks like it has something to do with the setting of variables, and the fact those two apps require Java.

I'm trying to isolate further now.

Anybody know what scripts (if any) get executed when on a login from XRDP, or how to force their execution?

So I did a tail on the xession errors that I found:

# tail -f .xsession-errors
/home/devdroid/android-sdk-linux/tools/android: 84: java: not found
/home/devdroid/android-sdk-linux/tools/android: 101: java: not found
exec: 114: java: not found

This seems to confirm that Java isn't found.

This seems odd to me since I have JAVA_HOME and JRE_HOME defined in /etc/bashrc, which is called from /etc/profile.

If anyone can help clarify what scripts are run to set variables when using XRDP, I'd love to know that.

In the meantime I created a launcher script for the app which sets the PATH and JAVA_HOME, so that they run properly.
