I am using java application to call cplex to build a model. It succeed.

However, when I new the java model above in the servlet with Tomcat, it occurs the following problems:

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

then repeat the same problems in red.

I'm wondering is there any difference between calling cplex with java application and calling cplex with javaweb application on tomcat?
