The problem is that the parameters for that method are pointers (by
reference). In CF, you pass by reference to a COM object by enclosing the
variables name in quotes. Javacast won't work there because it's not a
variable, which it needs to be.
Try this:
<cfset myValue = "SomeValue">
<cfset oEVR.Add("myValue", "oEVB")>
See here for more information:

Hope that helps,

Subject: [CFCDev] Problem CFC Method Call with COM Objects
Hi,
I am trying to invoke a COM method within a CFC method which a COM-object(s)
as parameter(s).
e.g.:
<cffunction name="test" access="private" output="false">
<cfset var oER = createObject("COM","Dllone.ER") />
<cfset var oEVR = createObject("COM","Dllone.EVR") />
<cfset var oEVB = reateObject("COM","Dllone.RB") />
...
<cfset oEVR.Add(javacast("string","SomeValue"), oEVB ) />
...
</cffunction>
Error: An exception occurred when executing a Com method.
The cause of this exception was that: AutomationException: 0x80020005 - Type
mismatch..
com.linar.jintegra.NativeObjRef.nativeIDispatchInvoke(Native Method)
The TypeLib Viewer of the DLL outputs:
~~~~~~~~~
Add(
[in, out] unsigned char* SomeValue,
[in,out, optional] _RB** RB);
~~~~~~~~~
As I cannot cast complex types I cannot find a solution to this problem. I
want a native CF implementation with no wrapper written in Visual Basic. Is
there anybody out there who can help me? Thanks in advance!
Magnus
