Get / Cast a Java Object

Does anybody know how to get (or Cast) a Java Object returned from a Java method call ?

Example:

<cfset someList = object1.method1(someString, JavaCast("float",someNumber),...)>

This method returns a list of Java object of type "Object2". ie. it returns List<Object2>

Now I attempted to loop thru each objects from the returned list, and invoke some method on them, using code similar to below,

<cfset var="#someList[index]#"/>

but ColdFusion does not seem to understand the object "var" as Java "Object2". Is there any way I can cast the "var" to "Object2"?

Thanks in advance.
