Problem using BAM 12c with BPEL

Hi All,
i have created a simple BPEL process in 12c. In this process I have defined business indicators ( 1 dimension and one measure). When I deploy the process I can see the data objects <CompositeName> Project and <CompositeName> Activity created, with the right columns. However when I run the BPEL process, the entries are created in the data objects, but sometimes the dimension columns are not filled. When I check in the BAM logs it is full of messages:
Internal Exception: java.sql.SQLIntegrityConstraintViolationException: ORA-00001: unique constraint (DEV_SOAINFRA.BEAM_8_STRING_1_UC) violated

Marc,
I was able to re-produce this issue. I have logged a bug and we will look into it and get back to you.

Problem using SQL Loader with ODI

Hi,
I am having problems using SQL Loader with ODI. I am trying to fill an oracle table with data from a txt file. At first I had used "File to SQL" LKM, but due to the size of the source txt file (700MB), I decided to use "File to Oracle (SQLLDR)" LKM.
The error that appears in myFile.txt.log is: "SQL*Loader-101: Invalid argument for username/password"
I think that the problem could be in the definition of the data server (Physical architecutre in topology), because I have left blank Host, user and password.
Is this the problem? What host and user should I use? With "File to SQL" works fine living this blank, but takes to much time.
Thanks in advance

I tried to use your code, but I couldn´t make it work (I don´t know Jython). I think the problem could be with the use of quotes

if retVal == 1 or retVal > 2:
raise 'SQLLDR failed. Please check the for details '

Problem using CORBA clients with RMI/EJB servers..!!!???

Hi,
I have a question on using EJB / or RMI servers with CORBA clients using
RMI-IIOP transport, which in theory should work, but in practice has few
glitches.
Basically, I have implemented a very simple server, StockTreader, which
looks up for a symbol and returns a 'Stock' object. In the first example, I
simplified the 'Stock' object to be a mere java.lang.String, so that lookup
would simply return the 'synbol'.
Then I have implemented the above, as an RMI-IIOP server (case 1) and a
CORBA server (case 2) with respective clients, and the pair of
client-servers work fine as long as they are CORBA-to-CORBA and RMI-to-RMI.
But the problem arises when I tried using the RMI server (via IIOP) with the
CORBA client, when the client tries to narrow the object ref obtained from
the naming service into the CORBA idl defined type (StockTrader) it ends up
with a class cast exception.
This is what I did to achieve the above results:
[1] Define an RMI interface StockTrader.java (extending java.rmi.Remote)
with the method,
public String lookup( String symbol) throws RMIException;
[2] Implement the StorckTrader interface (on a PortableRemoteObject derived
class, to make it IIOP compliant), and then the server to register the stock
trader with COS Naming service as follows:
String homeName =....
StockTraderImpl trader =new StockTraderImpl();
System.out.println("binding obj <" homeName ">...");
java.util.Hashtable ht =new java.util.Hashtable();
ht.put("java.naming.factory.initial", args[2]);
ht.put("java.naming.provider.url", args[3]);
Context ctx =new InitialContext(ht);
ctx.rebind(homeName, trader);
[3] Generate the RMI-IIOP skeletons for the Implementation class,
rmic -iiop stock.StockTraderImpl
[4] generate the IDL for the RMI interface,
rmic -idl stock.StockTraderImpl
[5] Generate IDL stubs for the CORBA client,
idlj -v -fclient -emitAll StockTraderImpl.idl
[6] Write the client to use the IDL-defined stock trader,
String serverName =args[0];
String symList =args[1];
StockClient client =new StockClient();
System.out.println("init orb...");
ORB orb =ORB.init(args, null);
System.out.println("resolve init name service...");
org.omg.CORBA.Object objRef
=orb.resolve_initial_references("NameService");
NamingContext naming =NamingContextHelper.narrow(objRef);
... define a naming component etc...
org.omg.CORBA.Object obj =naming.resolve(...);
System.out.println("narrow objRef: " obj.getClass() ": " +obj);
StockTrader trader =StockTraderHelper.narrow(obj);
[7] Compile all the classes using Java 1.2.2
[8] start tnameserv (naming service), then the server to register the RMI
server obj
[9] Run the CORBA client, passing it the COSNaming service ref name (with
which the server obj is registered)
The CORBA client successfully finds the server obj ref in the naming
service, the operation StockTraderHelper.narrow() fails in the segment
below, with a class cast exception:
org.omg.CORBA.Object obj =naming.resolve(...);
StockTrader trader =StockTraderHelper.narrow(obj);
The <obj> returned by naming service turns out to be of the type;
class com.sun.rmi.iiop.CDRInputStream$1
This is of the same type when stock trader object is registered in a CORBA
server (as opposed to an RMI server), but works correctly with no casting
excpetions..
Any ideas / hints very welcome.
thanks in advance,
-hari

On the contrary... all that is being said is that we needed to provide clearer examples/documentation in the 5.1.0 release. There will be no difference between the product as found in the service pack and the product found in the 5.1.1. That is, the only substantive will be that 5.1.1 will also
include the examples.

With reference to your and other messages, it appears that one should not

We currently publish an IDL example, even though the IDL programmingmodel in Java is completely non-functional, in anticipation of the support
needs for uses who need to use IDL to talk to the Weblogic server,
generically. This example illustrates the simplest connectivity; it does not
address how
to integrate CORBA and EJB, a broad topic, fraught with peril, imo. I'llnote in passing that, to my knowledge, none of the other vendors attempt
this topic either, a point which is telling if all the less happy to hear.
For the record then, what is missing from our distribution wrt RMI-IIOPare a RMI-IIOP example, an EJB-IIOP example, an EJB-C++. In this you are
correct; better examples are forth coming.
Still, I would not call our RMI-IIOP implementation fragile. I would saythat customers have an understandably hard time accepting that the IDL
programming model is busted; busted in the sense that there are no C++
libraries to support the EJB model, and busted in the sense that there is
simply no
support in Java for an IDL interface to an EJB. Weblogic has nothing to doit being busted, although we are trying to help our customers deal with it
in productive ways.
For the moment, what there is is a RMI (over IIOP) programming model, aninherently Java to Java programming model, and true to that, we accept and
dispatch IIOP request into RMI server objects. The way I look at it is this:
it's just a protocol, like HTTP, or JRMP; it's not IDL and it has
practically nothing to do with CORBA.

Please post request to the news group...
As I said, you must separate the idl related classes (class files and
java
files) from the rmi classes... in the rmic step, you must set a newtarget
(as you did), emit the java files into that directory (it's not clearyou
did this), then remove all the rmi class files from the class path... ifyou
need to compile more classes at that point, copy the java files to theidl
directly is you must, but you can not share the types in any way.
I fear that as soon as the call to narrow succeeds, the remainingapplication will fail to work correctly because it is too difficult otuse
an idl client in java to work.

Hi Eduardo,
Thanks for the help. That is the way I compiled my CORBA client, by

get a

Here's what I did;
+ Define the RMI interfaces, in this case a StockTrader interface.
+ Implement RMI interface by extendingjavax.rmi.PortableRemoteObject
making
it IIOP compliant
+ Implemnnt an RMI server, and compile using JDK1.2.2
+ use the RMI implementation to generate CORBA idl, using RMI-IIOPplugin
utility rmic;
rmic -idl -noValueMethods -always -d idl stock.StockTraderImpl
+ generate Java mappings to the IDL generated above, using RMI-IIOPplugin
util,
idlj -v -fclient -emitAll -tf src stocks\StockTrader.idl
This creates source for the package stock and also
org.omg.CORBA.*
package, presumably IIOP type marshalling
+ compile all classes generated above using JDK1.2.2
+ Implement client (CORBA) using the classes generated above, NOTthe
RMI
proxies.
+ start RMI server, with stockTrader server obj
+ start tnameserv
+ start CORBA client
Then the client errors when trying to narrow the obj ref from the
naming
service, into the CORBA IDL defined interface using,
org.omg.CORBA.Object obj =naming.resolve(nn);
StockTrader trader =StockTraderHelper.narrow(obj); // THIS
ERRORS..!!!
throwing a CORBA.BAD_PARAM exception.
any ideas..?

Please see the post on june 26, re Errors compiling... somewherein
there,
I suspect, you are referring to the rmi class file when you are
obliged
to
completely segregate these from the idl class files.

Problem using iPad mirroring with an Apple TV and 4:3 Projector

I'm a teacher and I've been using my iPad 2 in the classroom for about a year and a half. I would use Apple's VGA Adapter to connect to my projector, which worked fine. I just didn't like being tied down, and the dock connector would come loose very easily and lose connection to the projector, which interrupted the flow of the lesson.
So this summer, I got an Apple TV and a projector with an HDMI port so I could start using Airplay Mirroring to get the iPad screen onto the projector. But I'm having trouble with the aspect ratio. Forgive my drawing, but the genius at the Apple store had a hard time understanding my explanation, so I'm hoping this will help show what I mean.
My projector (ViewSonic DLP PJD5133) can be set to either a 4:3 or 16:9 aspect ratio (4:3, 800x600 is the native resolution). My projector screen in the front of the classroom is 4:3, so when the projector is set to 4:3, the image fills up the screen (which is what I want - it needs to be as big as possible so the entire class can see it clearly; plus it means all the output pixels are being used). When the projector is set to 16:9, the image is letterboxed (not ideal unless I'm showing a widescreen video or image).
The Apple TV's native aspect ratio is widescreen, and the iPad's native aspect ratio is 4:3, so if you use Airplay mirroring on a widescreen TV, the Apple TV will pillarbox the image (add horizontal black bars on each side), so that the image will not be stretched/distorted. (I know that it will show widescreen videos and a few widescreen-ready apps without the pillarbox, but the apps I use in class - Keynote, Noteshelf, etc. - don't fall in that category). The effect on my projector screen is a tiny 4:3 image taking up half the area it would have taken if I had used the VGA connection.
So in the Apple TV, I went to Settings>Audio & Video>TV resolution, and chose 800x600 60Hz (the max 4:3 resolution for my projector). Since the Apple TV is natively widescreen, it seems to accomplish this change be stretching the image vertically; but it basically works because the Apple TV home screen fills up the projector screen. However, when I turn on Airplay Mirroring on my iPad, the image does not fill up the screen. The Apple TV still puts a pillarbox on the image, so I end up with a distorted, square image of my iPad screen. It's the right height - the max 600 pixels for my projector - but it's not as wide as it should/could be.
Is there a setting that I'm missing? I understand that the Apple TV has to stretch its home screen image to accommodate the 4:3 resolution, but I think it should be smart enough to realize that if it's receiving a 4:3 image from the iPad and sending it out to a 4:3 TV, it doesn't need to pillarbox the image.
Before you answer - this is not a problem with the projector settings, and my Apple TV is not defective. You could simulate what's happening on your Apple TV, even if it's hooked up to a widescreen TV. In the Apple TV settings, change the TV Resolution to 800x600 as mentioned above (or any other of the 4:3 options). Now go to the Apple TV home screen, and note the amount of space the image is taking up on your screen (on a widescreen TV, it will be pillarboxed, and it will look like it's been squished horizontally). Then turn on Airplay mirroring on the iPad, and you'll see that the iPad image does not have the same width as the Apple TV home screen and it looks square/squished.
Also, while my projector does have a zoom function, it will not magnify the small iPad mirror image correctly (if I were to leave the Apple TV and projector on a 16:9 setting). It cuts off the top and sides. But even if it didn't crop the image, it's a digital zoom, so that option still won't fix the fact that I'm not getting a full 800x600 image on the projector. The same problem would apply if I were to move the projector farther away from the screen (so that the widescreen image takes up the full height of the projector screen, while spilling off the sides). I'll still have a lower resolution image, which isn't ideal since I'm often showing text on the screen through Keynote. Also, widescreen videos wouldn't fit on the screen, and I can't move the projector easily because it's fixed to the ceiling.
Sorry for the long explanation. Any ideas? I'd really appreciate some insight.

We have the same problem, and not only with ipads. Macbook Air is doing something similar. it can only use airplay with 1080 and 720 resolution, so the image is squeezed on a 4:3 projector. We use AppleTV 3 and Mountain Lion OS. We use ATVPRO from Kanex.
Apple must get its act together and fix this, they promise gold and green forests, but nothing works.
DO SOMETHING!

Problem using Time Machine with Seagate BackUp Plus Pls HELP!!

I have a late 2006 iMac (running OS 10.5.8) & am trying to back up using Time Machine with a new Seagate BackUp Plus drive. When I select the Seagate drive in Time Machine it tells me I msut first erase the (Seagate) disk. When I hit ERASE, I get a Time Machine error : COULD NOT UNMOUNT DISK. I see from various posts that 10,5 & 10,6 have issues with some external drives so want to upgrade to Mavericks (to get around this incompatibility issue): HOwever apparently my iMac is too old (by 1 year) to allow this. Can anyone give me any advice on how to get my iMac content backed up via Time Machine using the Seagate BackUP PLus drive I bought (becasue it is supposedly "compatible with PCs & Macs".
Thank you!!
Wendy

Your Seagate drive should work just fine. If it doesn't have any important data on it, try re-formatting it with Disk Utility to blank it out. Or run the Disk verify/repair and see if you can get it to fix any problems.
I have a Drobo FS too. You probably need a firmware update, they issued one a while back to fix problems with Time Machine. Use the Dashboard or download it from their support site, http://www.drobo.com/support/updates.php
Just curious how long you let it run after it "stalled". If it is a big file it could just be taking a while to copy over, do you see activity lights on the USB drive? The first time you use time machine let it run overnight, it's going to take a while, after that it will update quickly.
While you're at it, you might want to verify your start-up disk too with Disk Utility.

Any problem using PC fonts with Fontbook?

Hi all.
Are there any potential issues using PC fonts with Fontbook? I've downloaded a free internet font, ran the "Validate File" option, then loaded the font into Fontbook. Afterwards, I also ran "Validate Font" and it checked out okay.
It seems to be working, but I'm wondering if there is cause for concern that maybe down the line something funny will happen?
Any insight into this?
B.

It seems to be working, but I'm wondering if there is cause for concern that maybe down the line something funny will happen?
No, a font is just a font. All PC .ttf and .ttc fonts work in OS X. Windows Type 1 PostScript fonts (the ones with matching .pfb and .pfm extensions) do not.
The only real problem with free fonts is that the majority of them are not made well and can cause various problems because of it. Read section 14 of Font Management in OS X to see what those issues can be.

Problems using TFS 2008 with RoboHelp 11?

Adobe has not been able to resolve our company's connection problem with SharePoint thus far.
We do know that we can use TFS 2008 with RoboHelp because they have done that in the past. We are on RH11.
We need to know...Has anyone experienced any problems with using TFS 2008 with RH11? If so, what kind of problem(s)?

I've used TFS 2008/2010/2012 with RoboHelp without problems so far. You will always get the check in dialog, but that is the way it works, not a problem. This will become annoying when you are relocating lots of topics, since you will have to check in files a lot during these operations. But otherwise it works perfect in my experience.
As long as you make sure you have the 32 bit MSSCCI provider for the correct TFS version (MSSCCI 2008 for TFS 2008), you should be fine.

Does anyone have problems using Dragon NaturallySpeaking with Firefox

I have just started using Dragon NaturallySpeaking version 13 premium and I am encountering a few problems using it with Firefox. Completing text fields to login to various websites seems to be a major problem. With the cursor in the actual text field Dragon seems to not recognise the username or password that I dictate. I have made sure that the Dragon add-on within Firefox is activated and most of the other commands within the browser seem to work perfectly well.
Any help would be greatly appreciated.

This is most likely more of a Dragon problem than Firefox. I would suggest also opening a ticket on their end to. Most likely it just is not familiar with new versions of Firefox and has yet to be updated.

Problem using dual monitors with Radeon 9000 Pro and 2 x Samsung SM223BW

Hello all
I really need an expert opinion here:
I am using quite a lot my MDD 1.25Ghz that is still equipped with the OEM ATI 9000 Pro Mac Edition with 64MBs of Video RAM and as most if not all Mac-specific cards it has an ADC and a DVI port. I recently purchased a couple of Samsung monitors; the afore mention in the subject SM223BW. The monitors have two inputs, both DVI and D-SUB (Analog VGA or otherwise plain old RGB).
I have purchased a Formac ADC to DVI converter and connected this output to the DVI input of the first monitor. It works like a charm and the picture quality it is quite good (not as with an Apple Display but I couldn't afford them at this stage). For the second monitor I used a DVI to VGA cable (going from the DVI output of the card to the VGA In of the monitor).
Now here is the problem: The monitor that is connected ADC to DVI has all the available 16:10 ratio option that are suitable for this monitor. The DVI to VGA one gives me only a 1680x1050 and all the rest are 4x3 resolutions.
Would anyone know why this happens? Could it be a monitor issue? Could it be that perhaps TFT monitors offer different resolutions according to the input used. Or could it be the graphics card? Or even perhaps the cable?
Under OS X, same settings and same computer I am given more resolution options. Would that mean that it might be as well my beloved OS 9 in combination with the card?
Or am I stressing this too far?
Please any ideas are more than welcome
PS: I have a dual 2.0Ghz G5 connected to the rest of the DVI and VGA inputs to be able to run both without having to repatch. Otherwise a DVI to DVI connection would have made more sense and solved the problem

Hey Simon
I bought these monitors for their dual input functionality. The reason that I have the G4 connected to VGA is because I have another G5 connected the other way around in order to be able to use both computers, at any given time, with two screens.
Perhaps to make clear the connections I've done (if of course anyone is interested :)) ...
The G4 connects via ADC to DVI to the DVI input of Monitor No.1
The G5 connects via VGA to VGA to Monitor No.1
The G4 connects via DVI to VGA to Monitor No.2
The G5 connects via DVI to DVI to Monitor No.2
Another question would be why simply one mac isn't connected solely via DVI and the other one via VGA? The reason is that the VGA input looks awful on these screens for whatever reason. The image is seriously not sharp, the fonts looks horrendous and even with a lot of tweaking from the monitor settings, still I'd say the image is minging. If anyone knows why a VGA input can look that bad and still a monitor being in the market please let me know. It could be that this monitor is aimed to PC users and with the accompanying PC-only drivers all such are non-existent...Anyway I decided to go with the half DVI-half VGA solution to get the best out of the situation.
But on the question asked, I decided to use a 2 DVI input Avocent KVM that I've got with interesting results. I am pretty sure it is boring to read but if anyone has spare time here it goes:
The G4 connects via ADC to DVI to Monitor 1.
Monitor 2 DVI output connects to DVI KVM Input
The G4 connects via DVI to DVI to KVM Output 1
The G5 connects via DVI to DVI to KVM Output 2
The G5 still connects via VGA to VGA to Monitor 2
In this manner I am guaranteed to utilize the DVI inputs for both monitors, at least on my G4 and the G5 be forced to utilize one VGA. The plus side of the situation is that I can use both systems with the flick of a button without having to get up to change the Source on the monitors plus of course one keyboard and a mouse. Now here is the interesting bit:
Under OS 9, with the resolution 1280x800 on Monitor No.1 (the one connected via ADC to DVI) flips to - I think - 1680x1050 - it could be higher than that - with a thick black frame around the Desktop occupying a good chunk of the screen and the actual OS 9 looking minuscule at the center of it.
Monitor No.2 (the DVI to DVI connected one) looks just fine.
Now on top of that, when the G5 is switched on but the KVM is outputting the G4 desktop on Monitor No.2, whenever the mouse cursor slides on this monitor, it goes black! Just simply black and when I move the mouse cursor back on Monitor No.1 goes Desktop again.
Under OS X, none of the afore mentioned problems exist. Everything runs fine and I am give more 16:10 resolutions as well.
Confused? I am

Problem using Proxie server with Authentication & JEditorPane

I don't know if anyone has done this and if someone has I would really appreciate any help you could give me. I need to display a web page in a JEditorPane but the web page is accessed through a proxie server that uses authentication.

JEditorPane.setPage(new URL(urlStr))
this gives me an exception. The following is the exception message and printStackTrace

Problems using different scope with useBean

Hi all,
I've been trying over and over to place the data from my inputForm.jsp in request, session or even application scope and then try to retrieve the data from my process.jsp.
I can't understand why not the request object (emp) is available in my second jsp file. I'm having the same problem using sessionScope and applicationScope.
inputForm.jsp
<jsp:userBean id="emp" class="Employee" scope="request">
<jsp:setProperty name="emp" property="*" />
</jsp:userBean>
<form method="POST" action="process.jsp>
<input type="text" name="firstName">
<input type="text" name="lastName">
</form>process.jsp
<c ut value="${requestScope.emp.firstName}" />

The useBean tag has to be on the page WHERE THE BEAN IS BEING used.
The jsp:setProperty tag works from request parameters. So it has to be on the page that is RECEIVING the parameters - ie your second page.
You misspelled jsp:useBean.
Also your Employee bean must be in a package, and the useBean tag should use its fully qualified package name.
I will presume that your Employee class has appropriate get/set methods for firstName and lastName - ie getFirstName() and setFirstName()...
Try this:
inputForm.jsp
<form method="POST" action="process.jsp>
<input type="text" name="firstName">
<input type="text" name="lastName">
</form>process.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<jsp:useBean id="emp" class="com.mypackage.Employee" scope="request">
<jsp:setProperty name="emp" property="*" />
</jsp:useBean>
<c:out value="${requestScope.emp.firstName}" />

OWSM problems while associating clientAgent with BPEL process

Hi All,
Refering to the PDF *"Securing Oracle SOA Applications by Using Oracle Web Services Manager (Oracle WSM) Agents.pdf"* we made an clientAgent and associated that with a simple BPEL process. After that we did the following:
1) Change the Configuration Directory (with the component id of the clientAgent)
2) Enable Web Services Agent (which was not mentioned in the pdf).
3) Restart the SOA server.
At the time of executing the BPEL process it is giving an error like "internal server error". Log is not being generated for clientAgent. At BPEL domaim log it is giving the following error:
ORABPEL-02152
Instance not found in datasource.
The process domain was unable to fetch the instance with key "0ec681d22ef098ba:-529c35a1:1220cecf7e4:-7fcf" from the datasource.
Please check that the instance key "0ec681d22ef098ba:-529c35a1:1220cecf7e4:-7fcf" refers to a valid instance that has been started and not removed from the process domain.
Please reslove as early as possible.
Thanks in Advance.
Chandra.

There are a few things you can do when trying to troubleshoot this kind of problem:
1) tunnel the interaction between the BPEL server and the web service to see what SOAP messages are exchanged.
2) try to turn debugging of the ws layer on: BPEL Console>Manage Domain>Logging
2) email us your project, including the WSDL of your service so that we can take a look at it.
Finally, one best practice is to never think in terms of Java object. Instead always start by designing your WSDLs and XSDs thinking of ports and XML documents and then generate the stubs. This will guaranty that your service is interoperable.

Problem using Apple TV with TP-Link Wifi Extender

Hi,
I have been having problems connecting my Macbook Pro to my Apple TV via airplay and I believe it is due to the new wifi extender that I have installed in my home. Basically, the wifi extender uses the powerlines in the walls to extend the connection from my office at one end of the house, to my living room at the other. I am sitting here with my Macbook Pro in front of the TV using Apple TV, both connected to the same wifi SSID but still no option to mirror or extend my desktop onto the Apple TV. Can anyone help? Please? This is also affecting my Homesharing. It's as if the wifi extender is actually technically a second wifi network and my devices are getting confused and not finding each other.

I have the same Activity set up for my Harmony One. (First, I believe you mean "Devices," not "Components.") You appear to have some of your buttons customized wrong for the Apple TV Activity, since you said other Activities work fine, like Watch TV, etc. Within the Harmony software, go to the Activities (NOT Devices) tab, choose Watch Apple TV (or whatever you have named this activity), and then choose Customize Buttons. Then click the Standard Buttons tab, and then go down the whole list (of dropdown menus) to assign, re-assign, or confirm that all the proper Commands are assigned to all the proper Devices. For example, to correct your volume control issue, choose your Receiver to control the volume up and down Commands, etc. If this is done correctly, you won't have to go to Devices (for the receiver) any more on your remote to control the volume. It will all be controlled within the remote's Activity function, as you've requested. It has to work, since your other Activites are finding your receiver properly. If not, then Logitech's Harmony support has been helpful to me in the past, assuming you're still in warranty, etc. I hope this helps. Good luck!

Problem: Using iTunes 6 with multiple user accounts in XP

I recently installed iTunes 6.0.0.18 as an upgrade in Windows XP Professional. After installing the software and a restart, I attempted to use iTunes with success as the Administrator. However as another user, iTunes when launched will prompt the user with the user license agreement. When the user accepts the agreement, iTunes never opens, however I have noticed that the hard drive where the music files are located is continually accessed. When logging out an "End Task" message pops up stating that Quicktime Helper Files are still being used.
After the problem arose I attempted twice to completely uninstall iTunes, restart, cleanup the directories, reinstall, and then give all users full control permissions in both the directory structure of iTunes and the registry, with the exact same results.
Currently I have no fix for this problem, but I suspect that it is an issue with the software (iTunes 6.0.0.18). I have since downgraded back to iTunes 5.0.1.4 and am not having any issues.

Hello B,
So I finally had time to download the latest version of iTunes (ver. 6.0.1.3) and install it (logged on as the Administrator account). Please note that during the install I did get an error message that stated something to the effect that "a program tried to access memory location XXXX which is "READ" only." I believe this to be the new memory lock "virus" deterrent system that Intel has recently introduced with the latest 64-bit processors and motherboards, (which I have) but I am only guessing. In any case the installer finished in the background without incident.
After installing iTunes I launched it as the Administrator, and everything work just fine. I then logged off and logged in as my user account and attempted to run iTunes. I got the license agreement window, clicked "Accept" and nothing happened, but again I noticed that the Network card and my NAS were being accessed. I launched "services.msc" to check, as you suggested, to see if my QuickTime service had started. Much to my surprise the service was not listed. So I figured, well if there is such a service that needs to be launched then perhaps launching QuickTime would start this service, (still baffled to why the service is not listed in Windows Services). I launched QuickTime, and while leaving QuickTime open I then attempted to launch iTunes. Much to my surprise it started! I then closed both apps and have attempted to start iTunes several times since with success. A crazy fluke but, the steps listed above seemed to work for me. I can only hope that it helps others out who may be experiencing the same issue.
So it seems that my issue has been resolved. Thank you for all your time and efforts on this matter, I do appreciate it.
