Hello Luigi, experts,

I am trying to use QantlibSWIGJava for Bond valuation.
I wrote a simple program as under. But when I run I am getting below error.

2019-08-19 15:10:14,294  INFO  MONETA_PERF:37 [http-nio-8080-exec-1] - EVENT=[WEB] TIME=[2376]
2019-08-19 15:10:14,303 ERROR  org.apache.catalina.core.ContainerBase.[Tomcat].[localhost].[/].[dispatcherServlet]:182 [http-nio-8080-exec-1] - Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.RuntimeException: null pricing engine] with root cause

         at org.quantlib.QuantLibJNI.Bond_cleanPrice__SWIG_0(Native Method)
         at org.quantlib.Bond.cleanPrice(Bond.java:131)

Any idea what I am doing wrong.?

Another Q: How do I make same program run both Unix as well as Window env?

Do I load BOTH dll & so file  under

System.loadLibrary("QuantLibJNI");

Thanks,
