When I compile I added the .jar path by the comand:



javac -classpath <path to .jar> LPex1.java



this command works with no errors, but when I write the following command:



java -Djava.library.path=<path_to_shared_library> LPex1



I got the error message that I posted earlied. I think there is a permission problem where the library can not be accessed by the user account! but since I am new to the linux os I don't really know how to solve it!

 Notice that I am specifying the LD_library Path in the java command
 line!
 
 I was serching on the net and I found alot of similar bugs for different
 types of lib files and one suggestion was to download the JDK od SUN
 which I wasn't sure if it would be the solution of my problem.
 
 Please help if you know the solution.
 
Your problem is unrelated to eclipse. Your problem is  probably that you
o not add any jars or folders to your classpath. You are most likely
issing a "-cp $jar1:$jar2:...:$jarN" in your command besides the
Djava.library.path
