    Frequently Asked Questions about Rhino

     

    How do I create a Java array from JavaScript?

    You must use Java reflection. For instance, to create an array of java.lang.String of length five, do

    var stringArray = java.lang.reflect.Array.newInstance(java.lang.String, 5);
    

    Then if you wish to assign the string "hi" to the first element, simply execute stringArray[0] = "hi". Creating arrays of primitive types is slightly different: you must use the TYPE field. For example, creating an array of seven ints can be done with the code

    var intArray = java.lang.reflect.Array.newInstance(java.lang.Integer.TYPE, 7);
    

    When I try to execute a script I get the exception Required security context missing. What's going on?

    You've likely missed placing the Security.properties file in your class path at org.mozilla.javascript.resources.

    Can I use Rhino in a web browser?

    Rhino is a library for Java use, and not for general web browsers. However, a Java-based browser may use Rhino with scripts from a page in the same manner that any other Java program would.
