Calling 16 bit OLE server from Forte H2

All,
A Forte application loads and makes calls to a 16 bit OLE server. When the
Forte application terminates the 16 bit OLE server remains loaded and is
visible to the task manager.
It is surprising that the OLE automation server is visible after the
calling application has terminated and I have some questions:
1. Has anyone encountered this behaviour?
2. Does it cause problems?
3. Is there a known solution?
4. What is causing this behavior.?
The Forte application executes on a NT 4.0 client using Forte release H2.
The OLE automation server was written in VB. 4.0 and is a 16 bit solution.
Thanks for your help,
Eamonn.

not sure if anyone is watching this thread anymore but i have this scenario. i am using the excel connection manager in SSIS to create an excel spreadsheet with VS 2012. To do this from what I have read I am required to use the 32-bit driver for "Microsoft
Access database engine 2007", if I use the 64-bit driver I cannot connect to the Excel connection manager. i get 0xc020801c message.
i can install the 32-bit "Microsoft Access database engine 2007" and resolve this problem. but i also have a stored procedure that creates a spreadsheet (i use this because i have to leave some cells intact), it appears to require the
64-bit "Microsoft Access database engine 2007". in 32-bit mode i get the following message
Msg 7438, Level 16, State 1, Procedure sp_CreateGRfile, Line 26
The 32-bit OLE DB provider "Microsoft.ACE.OLEDB.12.0" cannot be loaded in-process on a 64-bit SQL Server.
so i need both the 32-bit "Microsoft Access database engine 2007" and 64-bit "Microsoft Access database engine 2007".
any thoughts on getting around this issue?

Calling foreign EJB server from Weblogic

Hi,
I'm trying to invoke an EJB hosted in an old PowerTier EJB Container from an 8.1 SP5 hosted EJB, and I'm running in to problems. (PowerTier is based on the JBroker ORB)
So far the only way I can get it to work is by replacing Weblogic's ORB implementation with the JBroker one:
-Djavax.rmi.CORBA.StubClass=com.sssw.jbroker.rmi.StubDelegate
-Djavax.rmi.CORBA.UtilClass=com.sssw.jbroker.rmi.UtilDelegate
-Djavax.rmi.CORBA.PortableRemoteObjectClass=com.sssw.jbroker.rmi.PortableRemoteObjectDelegate
But I'd like to avoid doing this if possible.
So I'd like to get this to work using the WL RMI-IIOP implementation to integrate with the PowerTier/JBroker server.
After looking at : http://forums.bea.com/bea/message.jspa?messageID=202437541&tstart=0
I tried the following:
Properties config = new Properties();
config.setProperty(

InitialContext context = new InitialContext(config);
URL changed to protect the innocent - but format maintained.
When the server executes this I get the following exception:
javax.naming.InvalidNameException: url does not contain a port

Any idea what is causing this exception? If I replace the '%20' with a normal spaces it makes no difference.

Calling a PL/SQL from Forte code

Hi, We are using the Sun UDS 5.1.3
I need to call directly from the code a PL/SQL stored procedure. It is true that this would defeat the Forte layer purpose but I have a very specific case. Is there an easy way to do so?

I don't remember how after all these years, but I remember that I made a native Informix call in a special way. So it seems logical that you should be able to do the same for Oracle...

Calling LabView ActiveX Server from TCL?

Does anyone have experience calling a LabView ActiveX server vi from
TCL? I created a simple VI with one control (labeled "A") and one
indicator (labeled "B") and a +1 adder between them. I can load and
open the VI from TCL:
package require tcom
set lv [::tcom::ref createobject "LabView.Application"]
set viPath "D:\\National Instruments\\LabView\\Activity\\a.vi"
set vi [$lv GetVIReference $viPath]
$vi FPWinOpen True
But when I try to send in data:
$vi -namedarg Call A 1
I get the error message "unknown parameter A".
I have also attempted to duplicate the "ActiveX Server" example
from the LabView help file, calling "Frequency Response.vi". This
approach encounters the same error message:
% package require t
com
3.0
% set lv [::tcom::ref createobject "LabView.Application"]
::tcom::handle0x013202F4
% set viPath "D:\\National
Instruments\\LabView\\examples\\apps\\freqresp.llb\\frequency
Response.vi"
D:\National Instruments\LabView\examples\apps\freqresp.llb\frequency
Response.vi
% set vi [$lv GetVIReference $viPath]
::tcom::handle0x01335AE8
% $vi FPWinOpen True
% $vi -namedarg Call Amplitude 10
unknown parameter Amplitude
If anyone can point me in the right direction, or give me an
example of how to do this I would greatly appreciate it.
TIA.

Try invoking the Call method without the -namedarg option. The
-namedarg option doesn't work the way you seem to think it works. The
-namedarg option provides a way to specify arguments named from the
method's parameter specification. For example, you discovered that the
Call method take two parameters named "paramNames" and "paramVals".
Tcom returns the error "unknown parameter Amplitude" because "Amplitude"
doesn't match either parameter name.

Getting APPSRV_JNDI_LOOKUP_ERROR while calling CAF Ext Serv from WebDynpro

Hi,
Iam developing a Composite application using CAF External Service & Application Service with a Web Dynpro UI wherein all the business logic is developed and invoked as web services. I do not face any problem in generating project code, building, deploying and running the application in my machine. But when I deploy the relevant .ear files to some other machine, I get APPSRV_JNDI_LOOKUP_ERROR and Iam unable to perform any operation which invokes a web service.
Iam only trying to deploy in some other machine the following .ear files available in my machine available at ...\LocalDevelopment\DCs\sap.com\project\... folder :-
sap.com~project.ear
sap.comprojectmetadata.ear
sap.comprojectpermissions.ear
sap.comprojectwebdynpro.ear
The following is the exception trace that I get :-

Please let me know :-
1) I find that always one more file called .ear is created under ...\LocalDevelopment\DCs\sap.com\project\webdynpro\_comp
But Iam unable to deploy this because it always throws invalid ear error. If I need to deploy this also, how do I do it ?
2) Is my deployment approach correct ? Is there any other simpler approach ?
3) If I need to deliver the project binaries to a third party how do I package them to ensure that it can be re-deployed at the other end ?
Thanks in advance,

Calling DCE RPCs from Forte

Hi all,
We are considering the use of DCE RPC with Forte.
I know that it is possible to both call-in and call-out to DCE from
Forte, and we are primarily interested in calling out, i.e.
presenting an existing set of DCE RPCs as methods in a virtual Forte
service object to be invoked by Forte clients. What we would like to
know is:-
In this scenario, what would be used as the interacting mechanism
between the Forte client and the virtual service object containing
the DCE RPCs? Would it be DCE instead of Forte messaging?
Am I correct to think that we won't be able to use Forte features
such as load balancing, fail-over, and asynchronous method invokation
on this virtual service object? Are there any other Forte features
which we won't be able to utilize?
Anyone can share their experiences on this subject?
Cheers
Michael Chiu.

Michael,
In this scenario where Forte is front-ending the DCE functions
with a service object, the Forte clients would use standard Forte
messaging to send messages to this Forte partition which in turn
would use DCE messaging to call-out to your DCE services. Given
that, the Forte clients could still use the benefits of Forte
messaging such as async, load balance, etc.

Why SCCM 20012 Install fails with remote 64 bit SQL Server but proceeds for remote 32 bit SQL Server

ODBC link to SQL3\SCCM2012,1432
ODBC uses SQL Native Client 10.0 (64 bit)
Both ODBC connections when TESTed pass and suggest connectivity to SQL Servers
Install process doe SCCM2012
Tried to install SCCM 2012 RC2 when logged in to SCCM Server as AD user account
SCCMAdmin, and when utilising the SCCM2012 SQL instance on
32 bit server of SQL install proceeds barring warning about 8GB rec, for SQL Server. Then fails on PKI certificate issue. Installation (chose HTTP for MP). I beleive the PKI failure as install starts is
due to the fact that SCCM 2012 needs its database server to b 64 bit ?
Thus i then tried to install SCCM 2012 RC2 when logged in to SCCM Server as AD user account SCCMAdmin, and
when using the SCCM2012 SQL instance on
64 bit server of SQL install proceeds but fails at checking stage and says:
SQL Server sysadmin rights FAILED SQL3.Domain_Name
Either the user account running Configuration Manager Setup does not have sysadmin SQL Server role permissions on the SQL Server instance selected for site database installation, or the SQL Server instance could not be contacted to verify permissions. Setup
cannot continue.
and
Site System to SQL Server communication WARNING SCCM.Domain_Name
A communication error has been detected between the specified site system and the site database computer. This error can occur when the site database server is offline or if a valid SPN has not been registered in Active Directory Domain Services for the SQL
Server instance hosting the site database. Setup cannot continue.
Why does the install of SCCM 2012 with 32 bit SQL proceed further than the install with 64 bit SQL, with the latter process failing as above error meesages show and yet both servers are set identically (apart from temporary turning off Firewall on the 64
bit server) and during the install the Databse Server specified is accepted ?

Thanks for the reply.
I can connect via ODBC to the the 32 bit SQL Server and the 64 bit SQL Server from the SCCM Server
The SQL Server Unit called SQL3 unit is a 64 bit SQL.
The SQL Server Unit called SQL is only 32 bit, but at least gets past the final checking stage and the error messages about sysadmin rights and Site System to SQL Server communication problem, and then fails with PKI certificate error message.
When trying to install SCCM specifying the 64 bit SQL Server as the Database Server it gives the 2 error messages at the final checking stage of the installation as listed.
So as I said what is confusing is the fact that if the SCCM install uses the remote 32 bit SQL Server it passes the final checking (although fails with PKI certificate message) but the 64 bit SQL Server set up exactly the same apart from the Firewall being
left off for the time being, fails at the final check stage with the 2 listed errors.
If I use a local 64 bit SQL Server the installation is fine.
Still would like to find out what cause the 2 issues for the remote 64 bit SQL Server, when ODBC seems fine, sysadmin rights have been given for the installer account and the SCCM computer account and SPNs have been set for the user account running the SQL
Services.

Calling OLE methods from TOOL

Where can I get an example of how to call Labview.exe (Active X Server) from Visual C++

I would like to Call Labview application (as Active X Server) from Visual C++. I need any type of exemple on how to do this, any input will be greatly apriciated.

In the summer there has been an example in the Developer Zone, but i can't find it again. I can send you the attached zipfile from that example. The example is resricted to single threaded applications. In multi threaded applications you must initialise OLE in the thread where you communicate with the active-X server.

Calling COBOL from Forte

Subject: Calling COBOL from Forte
We have a large complex COBOL program that we've purchased that we
currently run on our mainframe system. We are in the process of re-writing
our system into FORTE but we want to keep this COBOL program. This COBOL
program would need to be called from FORTE and it in turn would need to
call FORTE methods. The interface between FORTE and COBOL would be done by
passing large data structures as parameters containing both Character and
Integer data fields. Can this be done since I'm not looking forward to
having to re-write this entire program in FORTE?

-----------------------------------------------

Another alternative is to use the ExternalConnection class (in the
Framework project).
This would entail developing a "COBOL Function Server" on the mainframe to
"serve" the COBOL functions. I don't know if you can use COBOL for that,
but you should be able to use C, or PERL, or some other scripting language
that you can code a simple socket listener with on the mainframe.
This server would listen for requests to execute a COBOL function at a
designated port, call the COBOL function, and return its results via the
socket. On the Forte side you would use ExternalConnection to connect to,
send requests, and receive responses from the COBOL server. You can also
have a Forte server listen in on another port for requests from the COBOL
program and "serve" it Forte functions.
You would, in essence, be developing a COBOL/Forte gateway.
You would need to think about a simple application protocol to make the
requests/responses work. Something based on paramter=value pairs should
work well, is simple to code for, and simple to synchronize. For example :
request=get_employee_data
employee_no = 12345
<end_of_request>
request=produce_payroll_report
report_no=1705
format_no=1001
output_to=xyz
<end_of_request>
ExternalConnection class is a great way to create general Forte interfaces
to external systems. It does require some setting up, but is is worth the
effort.
Hope this helps.

There are a lot of other middleware supported by Forte like
ObjectBroker&DCE but COBOL is not supported directly by these productseither.

I am not aware of what kind of processing your COBOL and Forte apps

Re: Calling Actuate from Forte

Tanya,
Actuate supplies C-API's to both their report viewer and the report server.
There is also an ActiveX control version of the report viewer that you can
embed with Forte 3. There is example wrapper code lying around somewhere,
look on the Forte Shareware site.

Query 32 bit Access Database from 64 bit Sql Server

Hi All,
I have a task to query the Accessdb from Sql Server and below are the configuration details:
OS: Windows Server 2008 R2 Enterprise( 64 bit)
Sql Server: Sql Server 2012 enterprise (64 Bit)
Access : MS Office 2010 (32 bit)
I used the below queries to reap the data from access db.
SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0','D:\Product.accdb', Product) AS Product
(or)
SELECT * FROM OPENROWSET('MICROSOFT.ACE.OLEDB.12.0','D:\PRODUCT.ACCDB', PRODUCT) AS PRODUCT
following error returnd from both queries.
Error: "Msg 7438, Level 16, State 1, Line 2. The
32-bit OLE DB provider "Microsoft.Jet.OLEDB.4.0" cannot be loaded in-process on a 64-bit SQL Server."
Please help.
Ram MSBI Developer

not sure if anyone is watching this thread anymore but i have this scenario. i am using the excel connection manager in SSIS to create an excel spreadsheet with VS 2012. To do this from what I have read I am required to use the 32-bit driver for "Microsoft
Access database engine 2007", if I use the 64-bit driver I cannot connect to the Excel connection manager. i get 0xc020801c message.
i can install the 32-bit "Microsoft Access database engine 2007" and resolve this problem. but i also have a stored procedure that creates a spreadsheet (i use this because i have to leave some cells intact), it appears to require the
64-bit "Microsoft Access database engine 2007". in 32-bit mode i get the following message
Msg 7438, Level 16, State 1, Procedure sp_CreateGRfile, Line 26
The 32-bit OLE DB provider "Microsoft.ACE.OLEDB.12.0" cannot be loaded in-process on a 64-bit SQL Server.
so i need both the 32-bit "Microsoft Access database engine 2007" and 64-bit "Microsoft Access database engine 2007".
any thoughts on getting around this issue?

Tanya,
Please send any responses to [email protected].
I am currently working on an Invoicing project for Williams Conferencing in Denver, CO. We are using Actuate to generate invoices, in conjunction with an Invoicing application developed in Forte.
You have many options.
As far as integrating with Actuate, you can use their Actuate ActiveX controls, Requestor API or their Report Server API. You can read about the pros and cons of these methods in the "About the APIs" section of the "Actuate Application Programming Interfaces Guide" on page xxxi.
Using the Report Server API gives you more control than using the Requestor API. For example, we are currently unaware of a way of preventing versions of a report from being created when a report is regenerated, using the Requestor API. This can easily be accomplished using the Report Server API. But, the Report Server API is more difficult to use.
I am not familiar enough with ActiveX to comment on the ease and viability of using ActiveX to integrate Forte with Actuate.
Our approach is to create a C DLL using MS Visual C++ and integrate it with Forte. Our C DLL contains high level functions, such as GenerateInvoice(...) and PrintInvoice(...). Our high level functions contain calls to the Actuate Requestor API. Now that our C function are integrated with Forte, we are able to call them directly from our Forte application TOOL code.
For information on integrating C with Forte, read chapter 2 of the Forte book entitled "Integrating with External Systems". I have attached a document I wrote that enumerates the steps to integrate C with Forte.
The method we use to integrate Forte with Actuate is time consuming and tedious. If anyone knows of a better method, please let me know.
Kind Regards,

Calling an C++ Orbix server from an ejb

We have some C++ existing Orbix servers that we wish to call from an ejb. We are not using
Orbixweb. I ran the idl through Sun's idltojava. I was able to interface nicely from a stand-alone
Java client. I then put an ejb wrapper around the client stub. The first time I try to invoke a method,
I get the following exception:
org.omg.CORBA.BAD_OPERATION: The delegate has not been set! minor code: 0 completed: No
at org.omg.CORBA.portable.ObjectImpl._get_delegate(ObjectImpl.java:43)
at org.omg.CORBA.portable.ObjectImpl._request(ObjectImpl.java:92)
at com.manu.demo.any._AnyDemoStub.passSomethingIn(_AnyDemoStub.java:28)
at AnyDemoMenu.doSendChar(AnyDemoMenu.java:237)
at AnyDemoMenu.start(AnyDemoMenu.java, Compiled Code)
at AnyDemoEjbClient.main(AnyDemoEjbClient.java:26)
Any suggestions?

To answer your specific questions:
You asked two questions:
1. If you want to talk to Orbix, why are you trying to bring up the jdk orb?
Answer: We are using Orbix for the C++ server objects. We do NOT use OrbixWeb, Iona'a Java ORB.
We wanted to see if we could get it working just using the JDK ORB. So we have two Orbs talking to
each other. Even if we used OrbixWeb, we would still be using two orbs, although from the same
vendor.
2. Why are you trying to write a CORBA object into an RMI stream?
Answer. Well, I'm not. You are, or rather wls is. I'll review what I did. I have a C++ object defined in
IDL as a "Bank" interface. It is hosted by Orbix. We wanted to be able to reach the server from an EJB.
Running Bank through idlj produces java interfaces Bank and java classes BankHolder, BankHelper,
and BankStub. The client does not invoke methods on BankStub directly. All of these are in a
package I call BankServer. Any java client can use these to communicate with the C++ server object.
I defined an EJB with remote interface IBank, home interface IBankHome, and implementation object
BankBean. These are in package Bank. In the BankBean, I have this code (try-catch stuff ommitted):
package com.manu.demo.Bank;
import com.manu.demo.BankServer.*;
public class BankBean implements SessionBean {
private static Bank bank = null; // in BankServer
public void ejbCreate() throws CreateException {
String filename = "";
InitialContext ic = new InitialContext();
if (bank == null) {
// get file name - defined in deployment descriptor
filename = (String) ic.lookup("java:/comp/env/iorFileName");
// Read the stringified object reference from file.
BufferedReader reader = new BufferedReader
(new InputStreamReader(new FileInputStream(filename)));
String ior = reader.readLine();
reader.close();
// create and initialize the ORB
ORB orb = ORB.init((String[])null, null);
// Create object from stream
bank = BankHelper.narrow(orb.string_to_object(ior));
I now have the Bank (corba) object reference. Other methods in BankBean delegate requests to the
corba Bank. I NEVER invoke the BankStub.objectto_string method with the bad ORB.init() call. Nor
is it called by any of the other methods in the generated BankServer package. Look again at the stack
trace:
java.lang.SecurityException: ORBSingleton: access denied
at com.sun.corba.se.internal.corba.ORBSingleton.object_to_string

at weblogic.rmi.extensions.BasicServerObjectAdapter.invoke
at weblogic.rmi.extensions.BasicRequestHandler.handleRequest
at weblogic.rmi.internal.BasicExecuteRequest.execute
at weblogic.kernel.ExecuteThread.run
And you say you're confused? Since I can look at neither the WebLogic source code nor the wls
generated BankBeanEOImpl_WLSkel, I have no idea what is happening and why. All I can tell you
is that _BankStub.writeObject is not invoked when I use a Java client that is not in a wls ejb.
At any rate, the story has a happy ending. I changed a couple of lines of the generated _BankStub
code and everything works fine now. I notified Sun of the bug.
See http://developer.java.sun.com/developer/bugParade/bugs/4379317.html
Tahnks for your help.
>
The problem is in the code that the idlj compiler generates. Here is the
_BankStub.writeObject method. (generated code)
private void writeObject (java.io.ObjectOutputStream s)
try
String str = org.omg.CORBA.ORB.init ().object_to_string (this);
s.writeUTF (str);
} catch (java.io.IOException e) {}
Now, I'm even more confused. Why are you trying to write a CORBA object into an RMI stream?
>
The call to ORB.init() returns, by default, an instance of
com.sun.corba.se.internal.corba.ORBSingleton
Here is the code for
com.sun.corba.se.internal.corba.ORBSingleton.object_to_string
public String object_to_string(org.omg.CORBA.Object obj) {
throw new SecurityException("ORBSingleton: access denied");
This problem does not occur from a regular Java client to the
Corba object. This is undoubtedly due to the fact that the
writeObject method is called from wls, but not from my other
client.
I will report this problem to Sun. Even though this is not a
problem with wls per se, do you have any ideas as to work-arounds?
Maybe there are different ORB classes I can use.
The ORBSingleton is the Any factory, not the functioning orb. I don't really understand why there are two properties, but I expect what you want it to find out what IONA recommends for such a configuration.

Thanks a lot for your help.

I call my ejb remote, home, and implementation classes IBank, IBankHome,
and BankBean. I generated the Bank package with idlj. The Orbix Bank object writes out a
reference to itself using oject_to_string and writes it to a file. The BankBean.ejbCreate method
reads the file and reconstitutes the Java version of the Bank object by calling
ORB.string_to_object and the narrowing it. Other methods in the BankBean delegeate to
their corresponding corba Bank methods.
I invoke Weblogic with the following script:
set JAVA_CLASSPATH=.\lib\weblogic510sp5boot.jar;.\classes\boot
set JAVA_CLASSPATH=%JAVA_CLASSPATH%;.\eval\cloudscape\lib\cloudscape.jar;
set JAVA_CLASSPATH=%JAVA_CLASSPATH%;d:\classpath;

(Line breaks added for readability). D:\classpath is the location of my stuff.
I don't think the inclusion of the ORBClass and ORBSingleton class really has any effect here,
since I am using the defaults.

(Line breaks added for readability). D:\classpath is the location of my stuff.
I don't think the inclusion of the ORBClass and ORBSingleton class really has any effect here,
since I am using the defaults.
Now I get this:
java.lang.SecurityException: ORBSingleton: access denied
at weblogic.rmi.extensions.AbstractRequest.sendReceive(AbstractRequest.java:76)

I suspect that I need to add something to the Weblogic policy file. Do you concur? If so, what do
I need to do? Here is my current file (with comments removed)
