I am trying to run a program with cplex on linux server via putty and I get an error because of the cplex.

(on window the program run well).

Project files:

                   ProjectLinux/src/Main.java , Solver.java

                   ProjectLinux/cplex/cplex.jar , x86-64_linux (native library)

The line on the terminal to run:

                        javac -cp ../cplex/cplex.jar *.java

                        java -cp .:../cplex/x86-64_linux Main

(The program run but get error when cplex used)

The error I get:

java.lang.UnsatisfiedLinkError: no cplex1271 in java.library.path
java.library.path must point to the directory containing the CPLEX shared library
try invoking java with java -Djava.library.path=...
Exception in thread "main" java.lang.UnsatisfiedLinkError: ilog.cplex.Cplex.CPXopenCPLEX([I)J

        at Solver.solve(Solver.java:52)

Please if someone know how to solve that problem.

Thanks !

The JAR file is one of two files your application needs to use CPLEX. The other is a runtime file, libcplex1271.so. The line

try invoking java with java -Djava.library.path=...

tells you what you need to do. Add -Djava.library.path=<wherever CPLEX Studio is installed on remote machine>/cplex/bin/x86-64_linux/ to your command line (after making sure that the .so file really exists there).

Thank you for your answer.

I use the line:

        export LD_LIBRARY_PATH=../cplex/x86-64_linux

end it's work !
