Nino,

if you are not already using it, I recommend using the OpenJDK 8 provided for Ubuntu 16.04 as this will have best compatibility with native libraries installed on your system. It is up to date (8u131):
https://packages.ubuntu.com/xenial/openjdk-8-jdk

apt-get update
apt-get install openjdk-8-jdk

OpenJDK is build from the same source as Oracle JDK, and lacks only a few non-free and very new components (fonts, a few audio codecs, and JavaFX). An Oracle JDK for Ubuntu 16.04 should work just as well, so you can skip to the next step if you have one installed.

Likewise, you should be able to install the Ubuntu spatialite libraries with:

apt-get install libspatialite7

The Ubuntu 16.04 version is also up to date (4.3.0a, same a Nuno):
https://packages.ubuntu.com/xenial/libspatialite7

If you use the Ubuntu spatialite libraries, you should not have to set LD_LIBRARY_PATH.

Using the spatialite library compiled for Ubuntu 16.04 will ensure that library loading does not fail because of, for example, missing or renamed dependent libraries.

Kind regards,
Ben.

Hi Nuno,

Really I'm not very practical about java (I have basic knowledge), but I
guess my java installation (JRE) on Ubuntu 16.04 isn't good or it is not
well configured ! So I want to try again.

I'm looking for and I found this guide:
https://www.digitalocean.com/community/tutorials/how-to-install-java-with-apt-get-on-ubuntu-16-04

what do you think about ? .. or have you other tips ?

best regards
Nino

I just give it a try with last GeoServer trunk and is working:



I have two possible differences from your setup, I'm using Oracle JDK 8
and I have spatialite Ubuntu packages installed (this should not make
any difference):

ii  libspatialite-dev:amd64 4.3.0a-5               amd64        Geospatial
extension for SQLite - development files
ii  libspatialite7:amd64      4.3.0a-5               amd64
Geospatial extension for SQLite - libraries
ii  python-pyspatialite        3.0.1-10               amd64        Python
interface to Spatialite
ii  spatialite-bin                  4.3.0-2                 amd64
Geospatial extension for SQLite - tools
ii  spatialite-gui                  2.0.0~devel2-2    amd64
user-friendly graphical user interface for SpatiaLite

If you are curious the code that checks if the JDBC driver and natives
libraries are available:
https://github.com/nmco/geotools/blob/7d4dcbfba9b67ab6aae0b5b65f5366
334249147b/modules/library/jdbc/src/main/java/org/geotools/jdbc/
JDBCDataStoreFactory.java#L402-L410
https://github.com/nmco/geotools/blob/bd04ccd3f3b7f633f596f3ff93464a
8d4a13853c/modules/plugin/jdbc/jdbc-spatialite/src/main/
java/org/geotools/data/spatialite/SpatiaLiteDataStoreFactory.java#L74-L80

Hope this helps.

Yes, I already did . but It does'nt change anything!
I guess that the indications:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
java -Djava.library.path=/usr/local/lib

are incorrect or ambiguous !

I remember vaguely that you may need to define this variable too on Linux:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

Brad is giving you good questions, please share the logs, from the
description it seems that GeoServer is not finding the native library
it's looking for.

This is my system configuration:
- Ubuntu 16.04
- Tomcat 8
- Java 8 openjdk
- Geoserver 2.10.3

I have downloaded native library from:
http://docs.geotools.org/latest/userguide/library/jdbc/spati
alite.html#native-libraries
precisely the linux 64 bit version:
http://ares.boundlessgeo.com/geotools/spatialite-libs-linux-x86_64.zip

Then I have extracted  lib (in zip file) in a folder named
"spatialite-libs"
and I put it in /usr/local/lib/ folder.

I restart Tomcat 8 and run Geoserver; this is the log file:
https://drive.google.com/open?id=0B5Doub2YiDSednFrUGVoVm9Cc1E

... thanks!
Nino
