Dear all,

I am using maven to build my jjava project. I am trying to give:

-Djava.library.path=/opt/ibm/ILOG/CPLEX_Studio1262/cplex/bin/x86-64_linux

as an argument in the POM file of my maven/java project. I have already added the following lines to the dependencies of my project:

<dependency>

<groupId>cplex</groupId>
<artifactId>cplex</artifactId>
<version>12.6.2</version>
</dependency>

I keep getting this error whenever the code using cplex is about to run: 

java.lang.UnsatisfiedLinkError: no cplex1262 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=...
java.lang.UnsatisfiedLinkError: ilog.cplex.Cplex.CPXopenCPLEX([I)J
    at ilog.cplex.Cplex.CPXopenCPLEX(Native Method)
    at ilog.cplex.CplexI.init(CplexI.java:6608)
    at ilog.cplex.CplexI.<init>(CplexI.java:629)
    at ilog.cplex.IloCplex.<init>(IloCplex.java:10313)
    at ilog.cplex.IloCplex.<init>(IloCplex.java:10328)

Can someone please help me. What code should I put in my POM file and where in order to get rid of this error. 

Thanks you so much. 

I see that you've edited your post a bit (I started by looking at the original text via email).  It seems you are mixing versions of CPLEX (12.4 and 12.6).  As of now, you still have a reference to 12.4 above in the POM file snippet.  I can't help with maven specifically, but I'd make sure you are using the correct cplex.jar file (should be under /opt/ibm/ILOG/CPLEX_Studio1262/cplex/lib, for 12.6), and that you don't have any mixing of versions anywhere else.

Finally, it looks like you're using a 64-bit installation (i.e., from x86-64_linux above).  I think you'll want to use the -d64 switch for java.

I am sorry for the mistake.... i was looking at another file and I think I copied the text from there. Now I have corrected that. I am indeed using the same version of cplex and I have made sure that i am using the correct jar file. Still doesnt work.... I already have d64 switch for java.....

I couldnt find a way to put the cplex library path in the pom file, so I did a work around by changing the java environment variable.

1) open the bash.bashrc file in the etc folder in edit mode

2) add this line to the very end:

    export LD_LIBRARY_PATH=/opt/ibm/ILOG/CPLEX_Studio12xx/cplex/bin/x86-64_Linux

3) you are good to go
