Gurobi Cloud GurobiJni60 unsatisfiedlink error possibility

[Brandon Seet]

Hi,

I've been trying to meddle around with my AWS Gurobi AMI as mentioned in the previous few posts. It has been throwing me the unsatisfiedlink error for the past two days - claiming that i am unable to find the GurobiJni60.jar within the opt/gurobi/linux64/lib folder. so i went to change the name of the gurobi.jar and libGurobiJni60.so files within this files to GurobiJni60.jar and GurobiJni.so files respectively and a error has been reflected to me on my command prompt. (This seems like some improvement/advancement to me, could it be that the Gurobi java stuff on the AMI cloud has not been updated to work properly?)

java -classpath ../../lib/gurobi.jar:.: Callback ../data/p0033.mps

Exception in thread "main" java.lang.NoClassDefFoundError: gurobi/GRBCallback

        at java.lang.ClassLoader.defineClass1(Native Method)

        at java.lang.ClassLoader.defineClass(ClassLoader.java:800)

        at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:14            

In my opinion it might be due to the fact that it's still trying to look for gurobi.jar file instead of the GurobiJni60.jar file. Is there anyway to solve this? or have i done it the wrong way?
