    I am trying to get CPLEX Academic version 12.5.1 to work with the Java API on an Ubuntu 12.04 - 64 bit machine.

    CPLEX was installed from the file "cplex_studio1251.linux-x86-64.bin". The installation was successful and it is possible to start Optimization Studio.

    I imported a small tested project into eclipse, added cplex.jar to the classpath. Then I located the binary libraries and started the program with:

    -d64 -Djava.library.path= /opt/ibm/ILOG/CPLEX_Studio1251/cplex/bin/x86-64_sles10_4.1

    as vm arguments.

    This results in the following error message:

    Error: Could not find or load main class .opt.ibm.ILOG.CPLEX_Studio1251.cplex.bin.x86-64_sles10_4.1

    What might be the problem here?

    Do you really have a blank after -Djava.library.path=? If so then I guess this is the error. Try removing that blank.
