[libreoffice-users] Re: UNO with Libreoffice 5 (64-Bit, Win) and Java

Salve Stephan,

Thanks for your kind reply. I too thought it should work, but to my 
disappointment it doesn't so far, unfortunately.

The exact same configuration runs however when I use Libreoffice (LO) v5 in 
32-Bit being UNO-called from within a JVM 32-Bit. (I'm using the moveable 
32-Bit LO version from Portableapps for that purpose, so I can have both the 
moveable 32-Bit and the installed 64-Bit LO version in one Virtualbox.)

With "Depends tool" do you mean the Depency Walker (depends.exe) ? 
http://www.dependencywalker.com/
I didn't find another tool which would sound similar to what you mentioned.

In any case, I fail to open my Java program with "Depency Walker", since the 
latter wants to open "Windows modules" only, i.e. ".exe", ".dll" files.
However I start my Java program with a ".bat" script which the Depency Walker 
doesn't want to open:
 java -cp myapp.jar;unojarfiles.jar myclass

Do you have any hint please how I could trace my Java program with your 
mentioned Depends tool?

I'm wondering if anybody ever successfully spawned the brand new LO5 64-Bit 
on Windows from within Java and UNO?

Greetings,
Aurelius
