Com object implementation in forms 9i

Has anyone actually implemented this? We have a 3rd party application (imaging software) that has .dll's that under forms 5 we have accessed within the forms pl/sql. Under 9i, I understand the need to create a javabean for this com object and then from pl/sql use the fbean package to implement it.
The example I've seen of this is the Microsoft Word one documented in "Client Side OLE Integration from Oracle9i Forms". I find this article to be very confusing. Does anyone have a link to anything that may provide better info?
One particular question I have is do I need to create a javabean on the Jacob package first and then the com objects for my 3rd party application? Or can I just directly create a javabean on my com objects?
Any info in regards to this would be appreciated.

JACOB provides a series of APIs that you can use to call COM methods from within Java So you have to create a JavaBean which does these calls. That JavaBean can import the JACOB classes so you don't have to write that all again.

How to implement Com-Objects?

Hello,
I use an ActiveX software which should be implemented in LabView. Now I want to know, if it is possible to implement Com-Objects from this ActiveX software in my LabView Application. When it is possible, where can I find this Com-Objects? Of course the ActiveX components are already implemented in LabView.

hello mobmon,
create an "Automation refnum" - control on your frontpanel (can be found under the "Refnum" palette), then select your object or browse for it (right klick "Select ActiveX class"). after that you have to wire the control with the "Automation open" and "Close Reference" functions from the "ActiveX" palette. After that you have access to methods an properties.
hope it works

Implementing Objects in Oracle Forms

Am preparing for my Forms exam and would really appreciate it if anybody knew where i could get online info/resource with examples on how to implement and manage objects in Oracle forms. Have downloaded 10g and the associated documentation about 200Mb which has got everything except detailed info on Oracle Forms and implementing objects.
Thanks
Gus

Thank you Rosario, not exactly what i was looking for at this moment but certainly something i will use as i will want to use PJCs, a very valuable link, thank you again :)
What i want to find out is there a similar type of guide to implementing object tables with relational tables in a simple form, as i have given it a try and haven't really got anywhere, so a step wise guide would be great.

GP Interactive form Callable object implementation

Hello experts,
I am trying to use a adobe interactive form as a callable object in guided procedure and when I do the testing the error I am getting is:
"Callable object implementation did not return output parameters"

Sending my callable object as interactive form thru workflow for approval

hai
I have created a sales order form as per the requirement given by sales head.Also i ve created a role in portal and have deployed my application implementing the rfc s required. i need to send my callable object(component1) to the saleshead with approve and reject button where when he approves notification mail should be sent to the required persons and if he rejects it should come back to me.(order initiator).i need to complete this soon and i dont have any idea about _+sending my callable object as interactive form thru workflow+_ .plz guide me with the steps(step bye step process) to be followed which ll help me to complete this project.

Can we know the reason why do you need to extract the Interactive Form from Workflow.When you are calling the workflow try to save the form in a shared folder and save the url of the shared folder in a field and try to acces it by using SAP Activity.You can create a button for that create an SAP activity and when you click on the button the Interactive Form can be opened.
Iam not sure weather i have answered your question or not?

Word 2007 COM object

I am having a heck of a time finding a good example of a word
COM object. I just upgraded from word 2000 to word 2007, in hopes
that would suddenly work for me (which honestly I didn't
expect...). In word 2000, this line worked fine, but not in 2007:
thisDoc.SaveAs("c:\MyDoc.doc");
Here is what I am trying to accomplish: I need to use values
submitted by forms and input it into a word document. The word doc
needs to have different paragraphs in different formats. I thought
I could build the paragraphs somehow, with formatting with
something like para1 = docrange.newparagraph(); then insert the
text and formatting into para1 and then insert para1 into the
document. It does not seem to be working at all. If someone can
link me to a good example I can figure it out from there, but I
don't seem to be able to find it. Here is my code so far:
<cfquery name="getAttorney" datasource="agreement">
Select * from Attorney where ID = #Form.attorney#
</cfquery>
<cfoutput query="getAttorney">
<cfset attornyInfo =
"#Name#
#email#
#Phone#">
</cfoutput>
<CFTRY>

<CFOBJECT
ACTION="CONNECT"
CLASS="Word.Application"
NAME="objWordApp"
TYPE="COM">
<CFCATCH>

<CFOBJECT
ACTION="CREATE"
CLASS="Word.Application"
NAME="objWordApp"
TYPE="COM">
</CFCATCH>
</CFTRY>
<CFSCRIPT>
/* This will open Word if running locally */
objWordApp.Visible = true;
/* This returns the 'Documents' collection the Word Object
thisDoc = objWordApp.Documents.add();
/* Save the document to a location */
thisDoc.SaveAs("c:\MyDoc.doc");
docRange = thisDoc.Range(0);
docRange.Style=-2;
docRange.InsertAfter("Header1");
docRange.InsertParagraphAfter();
docRange.Style=-3;
docRange.InsertAfter("I am the paragraph you requested");
docRange.InsertBreak();
docRange.InsertAfter("check me out... I'm on the second
page!");
para1 = thisdoc.paragraphs.count();
data = docrange.listparagraphs();
data1 = docrange;
/* Save the changes */
thisDoc.Save();
/* Close the document */
thisDoc.Close();
/* Quit Word */
objWordApp.Quit();
</CFSCRIPT>
<cfdump var="#para1#">
<cfdump var="#data#">
<cfdump var="#data1#">
The dumps do dump information on the related objects, giving
me methods, puts and gets, but I need more explantion than what is
actually provided. Para1 used to dump "1" even though I had more
paragraphs than that in the build. Since I upgraded to 2007, I have
not gotten it not to error out, I will try to save it as a docx,
but a doc is really more appropiate for my purposes.
Thank you for your time.

The last time I had to deal with a requirement like this,
which was
about 2000-2001, we eventually scrapped the word COM thing.
Even then
it was such a fragile and perilous solution, fraught with
problems and
headaches.
What we ended up doing, that was much easier, was to create a
.rtf, rich
text format, file. We could do all the required formating in
this
format, and 90% of the uses would have this file open in MS
Word and not
even know they did not get a .doc file.
How we did it was create a .rtf template with dummy text that
had all
the desired formating. Then we could read in the .rtf file,
which is
just a marked-up text file, not a binary, and string replace
the dummy
text with the dynamic text. Save it again and viola a rich
text
formated file with the required content.
These days, I would push for doing this in PDFs and use
ColdFusion's
<cfdocument...> and|or <cfpdf...> functionality.
But if it has to be
Word, I suppose it has to be Word.

Controlling Matlab via TestStand COM Objects

I am attempting to control MATLAB via teststand activex com objects. I set up my module to use the matlab 7 automation server, and when I try to run the sequence, I get this error:
"Create New Object" in automation call failed.
No such interface supported
One reason this can occur is if the interface of your COM server cannot be marshaled. This can happen if your server is not using the default OLE marshaling implementation and does not implement its own proxy and stub code. If you write your server using Visual C++ you can add the oleautomation attribute to your interface in order to use the default OLE marshaling implementation. Alternatively, COM does not require marshaling if the server's threading model is the same as the client thread's apartment. You can try changing your server's threading model or the client thread's apartment to avoid the need to marshal the interface."
Anyone know how to fix this?
-Joey

It turns out this issue was a bug within Matlab itself. The correct registry keys were not being added for the Matlab ActiveX server with version 7.2. The bug report is located here. Once the correct registry keys were added there was no problem calling the Matlab ActiveX interface.

Calling COM objects

I have client HTML forms sending info to the middle tier. On the middle tier are Microsoft COM objects that have the business logic. The middle tier is Windows NT.
Previously, Microsoft IIS was the applications server and ASP was used to access the COM objects.
How can I use Oracle9i Application Server to call the COM objects? I suppose that I could receive the client input in a java servlet and make CORBA calls via a CORBA-COM bridge to the COM objects. Is there a better solution? If I have to do the CORBA-COM, anything I should look out for? I suppose the performance can't be very good over that many layers.

Hi John,
Thanks for the reply.
I have already looked into those topics which talks about Jintegra( com2java tool) and EZ Jcom .Basically these generate the java proxy classes, which is tedious to manage.
In asp we have something like Server.createObject(...). Is there anything similar to this in jspx?

Adobe Plugin not able to access COM object in Protected mode

We have an adobe plugin for our application. The plugin creates a toolbar button in Adobe and on clicking this button, it invokes one of the form from our application to save the document record for the PDF file in the database. The plugin was working fine till Adobe 9. It stopped working in Adobe X with proctected mode ON. However, if we turn off Protected mdoe, it works fine.
I did some research and found that we need to modify the policy rules by creating ProtectedModeWhitelistConfig.txt file and appropriate registry for it. I did those steps and now I am not getting "Access denied" error when protected mode is ON but the plugin is still not working. On further debug, I found that it fails while trying to connect to SQL Server. It gives error "SSL Security Error". This is working perfectly fine without protected mode. Also It is not able to access COM objects. I guess both these things might be related.
Can anyone let me know what are we missing here?

I would recommend that open a formal support case, as working with Protected Mode is quite complex.

Executing plug-in through COM object

Hello,
I have tried to create plugin with ATL COM object for possibility execute the function into plug-in from my application. And have got Runtime Exception which refer to red line in code below ("Expression: gCoreVersion>=CoreHFT_VERSION_2")
The next list is my C# code for invoke function RunReplacen for COM coclass ConnectorToAcrobat
     Type type = Type.GetTypeFromCLSID(guid);
     ConnectorToAcrobat connector = (ConnectorToAcrobat) Activator.CreateInstance(type);
     connector.RunReplace(@"Part1.u3d");
The next C++ code is part of COM object
#ifndef MAC_PLATFORM
#include "PIHeaders.h"
#endif
STDMETHODIMP CConnectorToAcrobat::RunReplace(BSTR filePathToU3D)
      char myPath[MAX_PATH];
      wcstombs(myPath, filePathToU3D, MAX_PATH);
      ASAtom pathType = ASAtomFromString("Cstring");
     // Function of plug-in
      CreatePDFWith3DAnnotation(&name);
      return S_OK;
What is wrong? How can I workarround this problem?

No, plugin and COM object it is a one solid file.
Anyway, I've faced with new problems. The AVDocOpenFromFile(ASPathName , ASFileSys , ASText ) function works perfectly, but if file doesn't containe forms. And when I want to open file with forms I getting crash.
Next, works with multithreading.
ACCB1 ASBool ACCB2 PluginInit(void)
DWORD ThreadID;
HANDLE hThread = CreateThread(0,0, ThreadProc, NULL, 0, &ThreadID);
return MyPluginSetMenu();
DWORD WINAPI ThreadProc(LPVOID lpParam )
BSTR filePathToU3D = SysAllocString(L"Part1.u3d");
char myPath[MAX_PATH];
wcstombs(myPath, filePathToU3D, MAX_PATH);
ASAtom pathType = ASAtomFromString("Cstring");
//Unhandled exception at 0x56230fa0 in Acrobat.exe: 0xC0000005: Access violation reading location 0x00000044.
ASFileSys fileSys = ASGetDefaultFileSysForPath(pathType, myPath);
ASPathName name = ASFileSysCreatePathName(fileSys, pathType, myPath, NULL);
CreatePDFWith3DAnnotation(&name);
    return 0;
(this code works fine in one thread)

Problem instantiating COM+ object

Hi,
I'm trying to instantiate a com+ object using
<cfobject> and I'm getting:
An exception occurred when instantiating a Com object
The cause of this exception was that: AutomationException:
0x80070002
The com object is built in c# .net and implements the
iDispatch interface. We're running mx 7, and using the following
syntax to instantiate the object:
<cfobject type = "com" action = "create" class =
"COMService" name = "myCOMService" context = "local" />
Can anyone suggest any pointers?
Thanks,

Turns out it was a problem with the COM+ component. Googling
the specific error code 0x80070002 helped to uncover the
problem.

Pass a COM object across processes

Hi,
I need to pass a COM object from process A to B. I didn't find a good code example for IMoniker. So I am trying to test a simpler solution. Please refer to the following snippet of code. There is a problem. When the execution
reaches GetActiveObject in B, the system hangs. "HRESULT h" in several places returns S_OK. Does anybody have a clue? Please help me out. Thanks for your help in advance.
// the definition of the COM object
EXTERN_C const IID IID_IUniverse;
#if defined(__cplusplus) && !defined(CINTERFACE)
    MIDL_INTERFACE("91CAF3F6-BD4D-4DDC-9C35-59F5DB20D570")
    IUniverse : public IDispatch
    public:
// PROCESS A:
HRESULT h = RegisterActiveObject (cwApp, IID_IUniverse, ACTIVEOBJECT_STRONG , &dwRegister);
// PROCESS B:
HRESULT h = CoInitialize(NULL);
IUniverse *p = NULL;
HRESULT h = GetActiveObject(IID_IUniverse, NULL, (IUnknown**)&p);
if (p)

Unlikely. If, as I suspect, the problem is that the server thread blocks, then the client won't be able to obtain the interface pointer from it by any means. Any IPC mechanism you might want to use kind of assumes that both parties remain responsive.
WaitForSingleObject() is the opposite of "responsive".
The third party (3rd pty) provides a COM interface. I write a COM server A
In-process (a DLL) or out-of-process (an EXE)? From your description, I would assume in-proc.
that has an implementation for this interface. I believe the 3rd pty must have called CoInitialize(NULL) before it instantiates object A.
It must have, yes. This is only significant if A is an in-proc server.
The 3rd pty passes a COM object of IUniverse to A. I can call IUniverse's methods in A without any problem. The need here is to transfer the IUniverse object to another process B so that B can call IUniverse's methods. The problem
is that B hangs.
My guess is, B hangs because A hangs. In one of your responses, you suggest that you are calling WaitForSingleObject (waiting on process B's handle, I presume). In so doing, you have created a deadlock. B is trying to communicate with A to retrieve the
interface pointer, but A is waiting for B to exit.
After A registers IUniverse pointer (whether in ROT or as active object), it should return to the caller. Said caller likely spins a message pump - but by blocking and not returning, you don't allow it to run.
The thread where A sits is created in the 3rd pty. If I understand you correctly, the 3rd pty must "retrieve and dispatch window messages in a timely manner". I think it does because it calls A when a window button is clicked.
3rd pty would, if only A would let it. By sitting in the message handler, A prevents the caller from retrieving messages in a timely manner.
But I don't know whether I should use Class, File or Item IMoniker.
Item moniker is the easiest to use by far. It just wraps a piece of text. You create one with CreateItemMoniker: pass L"!" (by convention) in the first parameter, and arbitrary string in the second. Both parties (one that registers in ROT, and
one that picks up) should agree on and use the same string, of course.
