I am trying to load to Tomcat 7 in linux a java api of a C++ library (freeling). After reading several manuals about how to load a jni library (using LD_LIBRARY_PATH, Wl, rpath in the compilation, ldconfig...) I can't load the library.
I have to say that firstly I wrote a java standalone application and the library is loaded correctly. The problem appears when I transform the standalone application in a axis2 web service. I have followed the pojo axis2 approach to build the service, and them I have embebed axis2 in tomcat. The error appears when I try to run the service. Also, I have to say that the system.loadlibrary works, and the error is returned when the first method of the library is called.
The error that I get when I call the web application is the following:
