The following table lists how ColdFusion converts data returned by Java methods to ColdFusion
data types:
Java

char/Char
short/Short
int/Integer
long/Long
float/Float
double/Double
String
java.util.Date
java.util.List
byte[]
char[]
boolean[]
String[]
java.util.Vector
java.util.Map
Resolving ambiguous data types with the JavaCast function
You can overload Java methods so a class can have several identically named methods. At runtime,
the JVM resolves the specific method to use based on the parameters passed in the call and their
types.
In the section "The Employee class" on page
for the SetJobGrade method. One method takes a string variable, the other an integer. If you
write code such as the following, which implementation to use is ambiguous:
<cfset emp.SetJobGrade("1")>
The "1" could be interpreted as a string or as a number, so there is no way to know which method
implementation to use. When ColdFusion encounters such an ambiguity, it throws a user
exception.
