how can i get dynamicly the name of the 6th enum-const from the "BOOP"-enum?

${org.java.some.MyClass."$enumName"[5]}

doenst work.

Answer 1

This should work :

public interface MyClass{static enum BOOP{a,b,c,d,e,f}};

${org.java.some.MyClass.BOOP.values()[5]}    // prints f

Additionally, you can't get the element with index 6 due to the array is 0-based and you do not have 7 elements in your enum.

Answer 2

I got it by myself

<%=org.java.some.MyClass.class.getDeclaredClasses().find{it.simpleName=enumName}.values()[5]%>
