Hi all,
Long in short, my MATLAB R2013a continuously starts with error:
Jul 2, 2013 11:21:08 PM com.almworks.sqlite4java.Internal log
INFO: [sqlite] Internal: loaded sqlite4java-osx from /Applications/MATLAB_R2013a.app/java/jarext/sqlite4java/libsqlite4java-osx.jnilib
Jul 2, 2013 11:21:08 PM com.almworks.sqlite4java.Internal log
INFO: [sqlite] Internal: loaded sqlite 3.6.23.1, wrapper 0.2
This happens on my both MACs which running OS X 10.8.4 and OS X 10.9 DP2 respectively. The java version installed on my computers are:
java version "1.6.0_51"
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-456-11M4508)
Java HotSpot(TM) 64-Bit Server VM (build 20.51-b01-456, mixed mode)
and
java version "1.6.0_51"
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-457-11M4509)
Java HotSpot(TM) 64-Bit Server VM (build 20.51-b01-457, mixed mode)
respectively.
MATLAB are installed on both computer freshly by default options, and I have checked the permission of the file "libsqlite4java-osx.jnilib" is 555. Can anyone help me to resolve this problem? Many thanks!
BTW: I always choose to ignore this error and all MATLAB functions seems running seamlessly.

Hi,
what does this give for you
>>org.apache.log4j.Logger.getLogger('com.almworks.sqlite4java').getLevel
ans =
[]
For me its empty. Maybe you have set some loglevel at some point? In the case its set to something disable it again using:
a = org.apache.log4j.Logger.getLogger('com.almworks.sqlite4java')
a.setLevel(org.apache.log4j.Level.OFF)

It shows
>> a = org.apache.log4j.Logger.getLogger('com.almworks.sqlite4java')
a =
org.apache.log4j.Logger@578ef2b6
on my computer. And your trick actually works! Thanks so much!

Sorry, I did not carefully see the "getLevel" for getting "a", and after the trick it's now empty. Anyway the trick works! Many many thanks!

Hi, it's not an error. It's just an info log. I think you can safely ignore it

the problem comes from that there is a deleted file which is still in your matlab path. so, set the matlab path into its default. you may after add the other path you need to use as well. then restart your matlab and problem is solved.
