You must not install Java package for octave 3.8 or later.
The java facilities are implemented in octave itself from Octave-3.8 
if it is configured.

If you use Octave-3.8.2 from http://mxeoctave.osuv.de/, try the latest one.

If you have 32 bit excel 2010, you can use COM interface.

***************************************************
For the Excel/COM interface:
 A windows computer with Excel installed
 Octave-forge Windows-1.2.1
***************************************************

The above only required for xls file. For xlsx file, there is not required java 
nor COM interface.

I recommend that you to install the latest version of io package by

>> pkg install -forge io

The you can install the latest io package.

Hope the above helps.
