Can you please tell me how to set up to run this code(include jar file, and set -Djava.library.path=E:\ibmcplex\cplex\bin\x86_win32) in command ?

example should be like javac --...

                                      java -.....

Thanks

The easiest way probably is to look at how the examples are run from the command line. To see that go to one of these directories

cplex/examples/x86_windows_vs2010/stat_mda
cplex/examples/x86_windows_vs2010/stat_mdd
cplex/examples/x86_windows_vs2010/stat_mta
cplex/examples/x86_windows_vs2010/stat_mtd
cplex/examples/x86_windows_vs2012/stat_mda
cplex/examples/x86_windows_vs2012/stat_mdd
cplex/examples/x86_windows_vs2013/stat_mda
cplex/examples/x86_windows_vs2013/stat_mdd

and look at the file javamake or just type

nmake -f javamake execute

This will compile and run all examples. From the output of nmake it should be simple to figure out how to set java.library.path and classpath on your machine.

Fox example. I already click run.bat  and the result automatically displayed as follows. How can I get the the command lines that running by myself?

Now you are asking about running OPL. If you want to run OPL you should ask the question on the OPL Forum.

In order to see the commands executed by a .bat file you only need to remove the '@echo off' at the beginning of the file.

I dont ask OPL but just supposed click run.data is the way to run java code.

Can you please give me more hint about how to check the command line?

I am really not familiar what you writing below.

and look at the file javamake or just type

nmake -f javamake execute

Sorry, I don't know how to make this any clearer. What you need to do is

1. Open a command prompt
2. Change directory to one of the folders I listed
3. Run 'nmake -f javamake execute'

What exactly is the step you are having trouble with?

I am confused,  the directory you listed cplex/examples/x86_windows_vs2010/stat_mda is for vc++and vc project.

I cannot find any .java file in that. Is that directory same as java example? 

But can you find the file called 'javamake' in that directory?

The java source files are located in a different directory (cplex/examples/src/java) but the javamake file correctly references them by way of relative pathnames.

Yes, I can find the javameke but I dont have vc so I dnot have nmake.

Can you tell me the typical way  to run cplex +java code on unix?

Like how to include cplex.jar and set library path?

I am not clear why you are asking for Unix commands when your OS seems to be Windows?

Anyway, to run CPLEX+Java from the command line you have to

1. Include cplex.jar in the classpath (environment variable $CLASSPATH or command line option -classpath)
2. Include in java.library.path the directory that holds the cplexVERSION.dll (where VERSION is the version number of your CPLEX installation). The java.library.path can for example be set with the -D command line option.

Note that for compiling a class file you only need 1, not 2.

I have tried that successfully in Windows, but failed on OS.

Is there any differences to run cplex java command  between unix and windows?

I don't think there is difference other than the different path names.

What is the command you are trying to execute and what is the error you get?
