I'm using GDAL library java as a dependency in Java web application with<br>
Maven dependency:<br>
<br>
<dependency><br>
<groupId>org.gdal</groupId><br>
<artifactId>gdal</artifactId><br>
<version>1.11.1</version><br>
</dependency><br>
<br>
It contains a jar file and runs the native codes in C++ underneath which I<br>
had to install from packages in Centos. All these shared libraries are<br>
installed in<br>
<br>
ls -l /usr/lib/java/gdal/<br>
total 1380<br>

However, the web application cannot link as it has a problem to link<br>
libraries, although what I can see from class loader of Java is:<br>
<br>
System.out.println(System.<wbr>getProperty("java.library.<wbr>path"));<br>
/opt/jdk1.8.0_25/jre/lib/<wbr>amd64:/opt/jdk1.8.0_25/jre/<wbr>lib/i386::/usr/java/packages/<wbr>lib/amd64:/usr/lib64:/lib64:/<wbr>lib:/usr/lib<br>
which contains the /usr/lib folder.<br>
<br>
The error from the GDAL java when I invoke a GDAL API (it does not have<br>
error if I don't invoke GDAL's methods so other methods still work, Web<br>
application can run normally) is:<br>
<br>
*Caused by: java.lang.<wbr>UnsatisfiedLinkError:<br>
org.gdal.osr.osrJNI.new_<wbr>SpatialReference__SWIG_1()J<br>
at org.gdal.osr.osrJNI.new_<wbr>SpatialReference__SWIG_1(<wbr>Native Method)<br>
~[gdal-1.11.1.jar:na]<br>
at org.gdal.osr.SpatialReference.<wbr><init>(SpatialReference.java:<wbr>117)<br>
~[gdal-1.11.1.jar:na]*<br>
<br>
I don't know how to solve this problem, tried to find lots of resources but<br>
no help as I want to deploy this as a Web application in Tomcat server. I<br>
could make it work when setting in NetBeans IDE with JVM option<br>
<br>
-Djava.library.path="/usr/lib/<wbr>java/gdal/"<br>
but I know this is not what web application can run.<br>
<br>
Thanks,<br>
