I'm having some trouble with .Net Integration. I have a .Net
class that has one function that takes a 3 parameters. It works
fine from .Net. However, when I try from ColdFusion, it can
instantiate the object just fine (cfdump dumps the object functions
with the correct data types as parameters), but when I call it, I
just a very generic error. In fact, the error is so generic that it
offers no error details at all. All it gives me is the line number.
I even went so far as to remove 2 of the parameters from the
.Net object so I could remove any possible complexity. But I still
get the same error.
The function basically takes the input strings and creates
another .Net object based on the input, which it then inserts into
the Microsoft Messaging Queue. The functionality of the classes
work perfect in .Net. When I rebuild the solution after I make
changes, the changes are represented in the CFDump, so it doesn't
seem like it is trying to use a cached version of the .Net dll (but
I'm not 100% sure of that -- is there a way of clearing any cached
.net objects? I noticed the following directory:
Y:\ColdFusion8\wwwroot\WEB-INF\cfclasses\dotNetProxy which seems to
have some jar files with dates that match my .Net objects).
I just can't seem to figure out what is causing the error.
The fact that it doesn't tell me anything doesn't help! Here is the
extent of the error message:
---------------------------------------------------------------
The error occurred in D:\Inetpub\NIAC-ANI-Core\TEST\MSMQ.cfm:
line 37
35 :
36 : <!--- send message using the AMS Queue Manager
--->
37 :
<cfset foo = obj_AMSQM.SendMessage( "hello" )>
38 :
39 :
---------------------------------------------------------------
In the past, when I've tried to pass in mis-typed or
unhandled data-types into the function it gave me this error:
------------------------------
Either there are no methods with the specified method name
and argument types, or the Set_MessageBody method is overloaded
with argument types that ColdFusion cannot decipher reliably.
ColdFusion found 0 methods that matched the provided arguments. If
this is a Java object and you verified that the method exists, you
may need to use the javacast function to reduce ambiguity.
------------------------------
So, I don't think it I'm trying to pass a mistyped variable
into the function. But without error details, I'm not sure how to
figure out what's wrong! I've attached the CF code I'm using below.
This is the function output from the CF dump:
==================================================================
Class Name: MessageQueue.AMSQueueManager
Method Return Type
-------------------------------------- ----------------------
SendMessage(java.lang.String) boolean
==================================================================
I've also tried to implement some error logging within the
.Net object to try to capture the error as if it occurs in the .Net
object, but log entries never appear. That makes me think that the
error is in CF before it even gets to the .Net object.
In addition, I've also successfully loaded the other .Net
class into CF (which builds the object to be passed to the message
queue passed on the params passed into the first object). The CF
Dump correctly displays the available functions. Most of the SET
functions work properly. But I have two different SETs that pass in
STRINGS. One of them works just fine, while the other gives me the
same generic, not details error. All of the GETs seem to work just
fine, except the one that is associated with the SET that is
failing.
This is the CFDump info from the second object I tried:
==================================================================
Class Name: MessageQueue.AMSQueueMessage
Method Return Type
-------------------------------------- ----------------------
Get_MessageBody() System.Xml.XmlDocument
Get_MessageBodyStr() java.lang.String
Get_MessageDate() System.DateTime
Get_MessageType() java.lang.String
Set_MessageBody(System.Xml.XmlDocument) void
Set_MessageBodyStr(java.lang.String) void
Set_MessageDate(System.DateTime) void
Set_MessageType(java.lang.String) void
==================================================================
I'm able to use the Set_MessageType just fine, but the
Set_MessageBodyStr fails with the generic, no details error. To me,
they look exactly the same. I had one of our senior .Net guys look
at my code (since I'm mainly CF with only a bit of .Net) and he
says it's perfect. I've attached the CF code I'm using below.
I guess I'm looking for any info on either what I'm doing
wrong or how to track down the error...
Thanks!
Kevin
