Usage
To call Java CFXs or Java objects, ColdFusion uses a Java Virtual Machine(JVM) that is
embedded in the process. You can configure JVM loading, location and settings in the
ColdFusion Administrator.
Any Java class available in the class path that is specified in the ColdFusion Administrator can be
loaded and used from ColdFusion, using the
cfobject
tag.
To access Java methods and fields, do the following steps:
1
Call the
cfobject
tag, to load the class. See the example code.
2
Use the
init
method with appropriate arguments, to call a constructor. For example:
<cfset ret = myObj.init(arg1, arg2)>
Calling a public method on the object without first calling the
init
method results in an implicit
call to the default constructor. Arguments and return values can be any Java type (simple, array,
object). ColdFusion makes the conversions if strings are passed as arguments, but not if they are
received as return values.
Overloaded methods are supported if the number of arguments is different.
Calling EJBs
To create and call EJB objects, use the
cfobject
tag. In the second example below, the WebLogic
JNDI is used to register and find EJBHome instances.
