Trying to get a JavaScript CBR rule function to instatiate a custom class in Sonic 7.5.2. I've added the jar for the class to the classpath of the container.

function rule () {

...

paramsHashMap = new java.util.HashMap(); // Works

...

java.lang.System.out.println("Trying to create an instance of MyFirstCustomService"); // Works

firstCustomService = new com.cerner.hie.raj.MyFirstCustomService(); // Fails - Exception trace follows

...

}

firstCustomService = new Packages.com.cerner.hie.raj.MyFirstCustomService();

will do the trick. The magic is the Packages. prefix in front of the real package definition.

Thanks. That was the solution that Sonic support came up with after trying different things.

A variation on this is to use the JavaScript function importPackage. This will allow you to import all classes within a particular pkg and not have to fully qualify your name every time, if that is desirable to you.

importPackage(Packages.foo.bar.name)
// "Name" is a class within package foo.bar.name.
function whatever() {
     name = new Name();
}

Thanks. This will be helpful.
