[Wine] Need Help debugging a Java based windows application to run

[pd1980]

Hi All,

I am trying to run a java based communication client developed for winidows to run on Ubuntu/Wine.

First I tried installing the app without having JRE under Wine, it halted with an error while installing JRE. So, I installed JRE separately under wine and then the application. It installed correctly. 

Now, when I run the application, it starts (I can see it under the process list) and then crashes (the process disappears).

I tried running the app through command line using the following. 
export WINEDEBUG=1 ; wine /path/tp/app.exe

Here is the output.

fixme:reg:GetNativeSystemInfo (0x327800) using GetSystemInfo()
USER.DIR=Z:\home\androit
USER.DIR=Z:\home\androit
java.lang.NullPointerException
	at java.io.File.<init>(Unknown Source)
	at com.company.app.findCurrentVersion(Unknown Source)
	at com.company.app.main(Unknown Source)
	at org.eclipse.equinox.launcher.Main.run(Unknown Source)

Can you please help me with this? What do I need?

Thanks,
PD
