How to use COM component in Forms 6.0 ??

Dear All,
We are developing Retail-Chain s/w and have a 3rd party s/w for credit card and
they give a .dll (not a ordinary dll ), .tlb file and sample VB code to integrate the 3rd party s/w.
Now i want to do the same task in my application using Forms 6.0.
Here is the sample code for VB :
' Sample VB code for invoking Plutus from VB-based ECR application
Private Sub Command1_Click()
' This is called when "Pay by card" is pressed in ECR application
Dim strIO As String
Dim lTrackingID As Long
' Add PlutusExchange v1.0 Type Library (TLB) as reference to the project
Dim plutObj As New PlutusExchangeLib.ExchangeObj
lTrackingID = 6 ' For testing, enter the scenario number as given in interchange spec doc
strIO = "T123,156" ' This is input to Plutus -- base amount in paise for Rs. 1.56 and ECR bill number: T123
' Bill number is only used for printing on Plutus chargeslip
plutObj.PL_DoTransactionEx lTrackingID, strIO
MsgBox strIO, vbOKOnly, "Plutus Response String"
' Parse this string to extract Plutus response. Only indication of successful transaction authorization is a valid auth code returned in response
End Sub
Plz. reply.
Note: I already register the .dll file and it showing in import OLE option under Forms 6.0.
Thanks

What are the simple to use COM library in your java code

No, he wants to use Windows COM objects!
@OP
It's not easy. You can try j-integra or ezjcom, which I tried years ago and was not too happy, but maybe
they improved or they are just fine for your needs. $$$ involved!
If you want to do it by yourself, it won't be easy at all, I promise, but it can be done with JNI or JNA.
If your interactions are very few and simple, maybe some workarounds could be found.

Thanks!!

As already suggested, you can display custom messages using AbstractTrace.
trace = (AbstractTrace)param.get( StreamTransformationConstants.MAPPING_TRACE );
trace.addInfo("G1-CYCLE is missing");
For more on coding front refer:
http://help.sap.com/javadocs/NW04/current/pi/com/sap/aii/mapping/api/StreamTransformation.html
To get this trace seen in MONI, set parameter TRACE_LEVEL in SXMB_ADM to 2.

Use COM (Component Object Model) libraries

I am new in Java but can write simple application already.
Now I have a need to write a simple application to manage my Nokia cellphone via a cable. I have downloaded the Nokia PC Connectivities SDK already. In the manual, it states that "all the libraries are implemented as COM (Component Object Mode) Libraries". All examples inside are Visual Basic...
How can I make use of the libraries in Java? What area of Java should I study for this purpose?
Thanks a lot.

Sun has a Java-COM bridge somewhere on the Java website for this purpose. Also, there are a heap of third-party ones too, both commercial and open-source. Just search for 'Java COM bridge' on Google.

So I donot know how to deploy a .properties file to the server and how to access this file in my Java code?
Thans and Best regards
Deyang

Hi,
1) put .properties file to your packege under src\packages folder (src\packages\com\sdn\properties\jco.properties)
2) load property:
     final InputStream is = getClass().getClassLoader().getResourceAsStream("com/sdn/properties/jco.properties");
     final Properties properties = new Properties();
     try
          properties.load(is);
     catch(Exception e)
          wdComponentAPI.getMessageManager().reportException(new WDNonFatalException(e), false);
