I installed the latest LibreOfficePortable Version 3.4.4 and JPortable1.6.29 on a W7x64 computer.
Starting Scalc I got a lot of warnings that Java is needed to run LibreOffice properly.
Via Extras/Options/Java I tried to choose my portable java installation, but the corresponding button has no effect, no browser window opens to select an installation,...
How to solve that problem.
Normally there is no need to choose the Java installation by hand (maybe iot even breaks things if you do). If java is installed on the local PC, LibreOffice will find it. If it is installed in the proper location, it will find it too.
What path did you install LibreOffice and JPortable to?
Normally, LibreOffice is in X:/PortableApps/LibreOffice and JPortable is in X:/PortableApps/CommonFiles or inside the LibreOffice/App/java folder.

Java is installed in D:\portableApps\LibreOffice\App\java.

While I've yet to encounter a problem running/starting LibreOffice Portable without Java, I always have to manually select jPortable for LibreOffice Portable. Moreover, when it's applicable, I don't like for LibreOffice to use the local Java install.
