Switching from Rhino to Nashorn

Question

I have a Java 7 project which makes a lot of use of Javascript for scripting various features. Until now I was using Rhino as script engine. I would now like to move to Java

Answer 1

To use the importClass method on JDK 8, we need to add the following command:

load("nashorn:mozilla_compat.js");

However, this change affect the execution on JDK 7 (JDK does not gives support to load method).

To maintain the compatibility for both SDKs, I solved this problem adding try/catch clause:

try{
    load("nashorn:mozilla_compat.js");
}catch(e){
}
