Is "live" SFP can use also as a light source for testing ?
Hey all
Can anyone recommend an oftic power meter with an LC or SC port? I just need to test for link on singlemode 1550 / 1310
Can i use the end GBIC as a light source?
I mean just to plug one end of the fiber run into the actual network equipment (switch/router with GLC-LH-SM / GLC-ZX-SM GBIC) and at the other side use a power meter to verify link and to check if i got the correct ligth level ?
Thanks!
For a power meter, you might take a look at the products offered by FIS (Fiber Instrument Sales). EXFO tyically make a quality unit, but FIS also has their own private labelled product (less expensive). There are also many other brands, most available with connector adapters to allow LC or SC testing. You could also purchase hybrid test patch cords so you only need one connector type on the power meter.
A GBIC/SFP transceiver can be used as a light source (just stay away from using an EDFA optical amplified output. Follow the test procedure described by THEFOA.ORG.
Hope this helps!

Hello everyone I have a question I use my Apple ID for iMessage but I want to know if I can use my friends Apple ID just for the App Store, can I do that ????
First on a computer try editing your ID to change the payment method to None.
How do I change my Apple ID Name or personal information?
You can change your Apple ID Name at My Apple ID. Click on Manage your Apple ID and sign in with your Apple ID name and password. Click Edit and enter the new information, then click Save Changes. Changes take effect immediately. You can also use My Apple ID to change your personal information, such as your mailing address or email address. See Changing the name you use for your Apple ID if you'd like more information.
If problems see:
Why can’t I select None when I edit my payment information?
Last:
Create a NEW account using these instructions. You have to use an email address not used with Apple before.

Can you use SQL as a data source for a project in the same way you can in Excel?
Excel allows you to create a data source that executes a SQL stored procedure, display that data as a table in a spreadsheet and have that data automatically refresh each time you open the spreadsheet. Is it possible to do the same thing in MS Project, displaying
the data from the stored procedure as a series of tasks?
Here's what I'm trying to do - I have a stored procedure that pulls task data meeting a specific criteria from all projects in Project Server. We're currently displaying this data as an Excel report. However, the data includes start dates and durations so
it would be nice to be able to display it as a Gantt Chart. I've played around with creating a Gantt chart in Excel and have been able to do a very basic one, but it doesn’t quite fit our needs.No, You can not use sql as a data source for a project.
You have 3 options to achieve it:
1. You can create a Sharepoint list with desired column ,fill desired data in that list then you can create a MS project from Sharepoint List.
2. You can create a SSRS report in which you can display grantt chart Joe has given you that link.
3. You can write a macro in MPP which will take data from your excel. In excel you will fetch data from your stored procedure. write a schedule which will run every day to update your data or
create an excel report in which will update automatically and write macro in mpp which will fetch the data then publish it so that it would be available to team members.

I was just wondering if I can use time capsule with my iphone for both back up and to access the hard drive on the capsule?
I don't think backup is supported but you may be able to access the TC's internal drive, from the iPhone, with an application like: NetPortal
Note: I haven't actually tried this app, so if someone else has and was successful in accessing the TC's drive they can certainly chime in.
Follow-up. Just downloaded and installed this app ... and I can now verify that it, indeed, can access both my TC's internal and externally attached USB HDD. -
Where can I get an additional power source for my MacBook Pro?
I am travelling to Europe next week and will be travelling on the road quite often. I would like to get some work done during that time. My laptop battery will inevitably run out of power during that time and I would like to carry an additional power source with me so I can get some extra juice when I am nowhere near an outlet.
I have the latest MacBook Pro where the battery is not removable.
Where can I get an additional power source for my MacBook Pro? I don't mind if it is a 3rd party product.you could get something like this: http://www.amazon.com/Energizer-XP18000-Universal-External-Netbooks/dp/B002K8M9H C
it's about the same cost as an extra battery used to be. there's a range of similiar products at Amazon, i'd check reviews. -
How can get a database like ****.SQL file for test in sqlplus in oracle8i
How can get a database like ****.SQL file for test in sqlplus in oracle8i,I am a beginner,thanks
I'll give it a guess as to what it is you want but I'm afraid you'll have to give some more information to go on. I appreciate it's difficult for people who are beginners or who don't have English as their first language.
Are you trying to run a SQL file? From SQL*plus you can do either of these:
SQL> start my_file
or
SQL> @my_file
N.B.: if th efile has a .sql extension you don't need to include it, but you do for any other file extension e.g.
SQL> @myfile.run

Is there anyway that I can sync this Motorola G5 dual, OS 10.5.8 with my ibook OS 10.6.8 so I can use the quicktime application on the Mororola? I need to network the two computers and if someone could kindly tell me how to do this with either wifi, USB, orFirewire, I'd be very grateful. My ethernet connection is in use and I only have one and no hub. Doing this will give me the ability to work for a site that needs my expertise in recording but I have old equipment right now on the recording end. No chance to upgrade at this point as we're broke and I'm severly injured, so I am trying to find a workaround that will let me access this copmuter, with snow leapord to work with the old one with (Motorola G5 dual w/10.5.8). It means a few bucks to us if I can make it happen, and my family really need to dough. It will keep me from having to convert things to a youtube format, take the extra time involved to do that, when, instead, I could just take screen recordings instead. Unfortunately, I don't have Pro Tools on this computer or all would be fixable.
I'm really hoping that you or someone else can help me get these two macs synced so I can do this. DO you think you can help me? Thanks so much! Scotty GoldbergThanks so much for your reply but that won't help in my current situation. Maybe I didn't make it clear. The latest version of Quicktime as new as it sounds doesn't support screen recording on a powermac G5 Motorola chip with OS 10.5.8 which is the highest os I can go with that machine. If I can sync the two computers so I can get the application to record from my newer computer then I'm ok. I just don't have the recording application for audio that I'm using to demo for the website on the laptop as it's about 10,000 dollars. So, I have to use the older computer to do the audio presentation and try to get the newer computer synced to it so I can use the new version that works on snow leopard to record a screen shot that will hopefully appear on my laptop instead of the old machine. Hope that makes sense. It's a bit confusing but in a nutshell it's like this:
1. I am a Pro Tools Instructor which is the state of the art application and recording device for audio and movie scoring and I have a new job where I make small snippets of tips using Pro Tools which I'd like to record with quicktime on screen as they happen
2. the best version of Quicktime Pro available for the Power Mac, OS 10.5.8 will not do screen recording on it.
3. I can use the Quicktime application from my newer laptop but I need to sync it to the old machine
4. I'm hoping but I don't know, if I do this, that I can record Pro Tools in action from my new machine buy seeing it on this laptop screen and then recording it with the new quicktime.
5. If I can sync the two computers, I'm hoping this can happen but I can't use my ethernet connection as I have it used to connect to my recording console and can't afford to buy anything new like an ethernet hub yo connect the two so I'm hoping that there's another way to connect them.
I hope that makes sense and that possible you or someone else can help. Thanks so much! Scott -
Can Discoverer be used as an XML Data source for XMLP ?
I am wondering if Discoverer can generate an XML Data Source for XMPL.
I have heard that Discoverer Viewer can have XML as an output. Is there a way of using this XML output with XMLP and, if yes, how to batch both steps ?Hi
My understanding is that Discoverer does not generate XML data as an ouput that XMLP can consume. The XML is does generate is actually an XML RDF for Oracle Reports.
XMLP is integrated thou, when you export your Disco report to PDF thats XMLP doing the conversion to PDF for you.

Using an EJB as a source for a Model
Hi,
Before starting with this post content it might be helpful to give you the desired output of what I am trying to do. Basically I need to have an HTML table that is populated from an EJB.
The current proposed solution is as follows: the Model that is associated with a TiledView will be used as client for the EJB. The Model will make use of the methods in the EJB to get different java.util.Collection objects for different Helper classes based on the find criteria.
For example, if the EJB represent a book and there is a home method to retrieve a list of books based of the book category. In this case the Model will act as a client of the EJB, retrieve the list of books and use the different methods in the Model, such as insert and retrieve, to get the list of books and to add a book up on request.
I know that my post might not be clear. But as I said, all that is needed is to have a TiledView that displays books information, which are retrieved from an EJB, and allow a user to select a book to display its information.
My suggested solution could be completely wrong, not visible and reflect a bad design. Please if any one went through such a situation give me a hint.
Regards,
Basil MahdiBasil,
This is some material I snipped from an internal Sun forum I posted to regarding a simple EJB Jato integration example.
I hate to give just any EJB JATO example because frankly there are so many different use cases with EJBs that no one example will match up against your needs. You can use an EJB
- in a Custom Model Operation you can encapsulate an EJB Method invocation
- in a Custom Command you can encapsulate any arbitrary code include calling an EJB
- as the backingstore for a CustomModel
- use a BeanAdapterModel to adapt to the value/transfer beans which are uses as parameters or return values of EJB methods
- use an ObjectAdapterModel to adapt an EJB directly by assigning the EJB reference in setObject() in the constructor of the OAM
As you can see, an EJB is just another business object API...its just that you acquire the reference with a few lines of ugly JDNI and Home interface APIs.
Nevertheless, here is some guidance. I would like to reinforce that there is no direct solution for adapting an EJB from BAM; EJBs are not JavaBeans. What is a solution is to have the parameters or return values of your EJBs use value/transfer object patterns in the form of JavaBeans. The BAM may be used to adapt to these parameters or return value of the EJB.
In short, when using BAM in a tileview to work with an EJB, there is little difference than using BAM at any other time, you the developer, must manage/code the placement of the EJB parameters directly into the BAM or in a scoped attribute to be used by the BAM.
In another example, you may have a SLSB which models an employee called EmployeeSupport. You may have a transfer object (JavaBean) of type EmployeeRecord. You may have operations on the EJB including:
public EmployeeRecord findEmployee(String employeeID);
public EmployeeRecord[] findEmployees(String location);
public void updateEmployee(EmployeeRecord);
One could create a BAM in the studio called EmployeeModel
You would set the JavaBean class to EmployeeRecord
You would run the Design Action to bootstrap the properties of EmployeeRecord as fields on the model
Now you have a model which is ready to adapt to EmployeeRecord bean.
Feel free to add material to the EmployeeModel to make a richer API; for instance you could encapsulate some EJB'ish code in their to act as a service locator for a EmployeeSupprt SLSB.
protected static EmployeeSupport support;
static {
javax.naming.Context context = new javax.naming.InitialContext();
Object objref = context.lookup("ejb/EmployeeSupport");
EmployeeSupportHome home = (EmployeeSupportHome)
javax.rmi.PortableRemoteObject.narrow(objref,EmployeeSupportHome .class);
support = home.create();
public static EmployeeSupport getEmployeeSupport() {
return support;
If you really wanted to hide the EJB'ishness of the EmployeeSupport you could even wrap the behavior and handle exceptions, etc.
public static EmployeeRecord findEmployee(String employeeID) {
return getEmployeeSupport().findEmployee(employeeID);
public static EmployeeRecord[] findEmployees(String location) {
return getEmployeeSupport().findEmployees(location);
public static void updateEmployee(EmployeeRecord record) {
return getEmployeeSupport().updateEmployee(record);
You could even help the view developer latch EJB transfer objects into the model for adaption; saving them from the effort
public void adaptEmployee(String employeeID) {
setBean(findEmployee(employeeID));
public void adaptLocation(String location) {
setBean(findEmployees(location));
public void save() {
updateEmployee((EmployeeRecord)getBean());
Create a search ViewBean, place a text field on it for an EmployeeID and button labeled Find. Leave the EmployeeID model binding default (to use a DefaultModel memory model). Open the handle request event method on the viewbean for the Find button.
public void handleFindRequest....{
EmployeeModel model = .....;
model.adaptEmployee(getEmployeeIDChild().getValue());
// display Edit page which has fields for editing the employee record
Create an edit ViewBean, with editable fields bound to the EmployeeModel; add an button labeled update
public void handleUdpateRequest....{
EmployeeModel model = .....;
model.save();
// do whatever is next ....
Notice that the we are jumping across request boundaries in this example. Using just default model reference configurations, the EmployeeModel will be created brand new during the Update request and there will be no bean currently adapted. Most likely, you would want to have the model (and hence its adapted bean) stored in HttpSession across at least these related requests. In this case the model reference used by the search ViewBean would have "store in session" true. and the model reference in the edit ViewBean would have "look in session" true.
What we recommend is that someone who understands the business tier design take the responsibility to create a set of "business delegates" as JATO models. An advanced technique would be to encapsulate these models in a component library JAR which multiple web applications can reuse. As you can imagine, there are so many ways to do the same thing. You could just as easily make a CustomModel or SimpleCustomModel to adapt to your EJB. You can also, if your EJB uses primitives or JavaBeans (or graphs of JavaBeans) for all parameters, use the ObjectAdapterModel to directly connect to an EJB. -
WIS 10883 using large Excel File as source for report in WebI RichClient
Hi,
I'm trying to use a relatively large Excel 2003 file, say 7000 rows and 19 columns, as a source for a report in WebI Rich Client. When selecting a range of only 1500 records and 19 columns everything works, when accessing the full 7000 (or originally 30,000) I get this error message.
Does anybody know of a size limit for this and if so an option to adjust it? The only resources for this very limited.
Thanks
Norman RuppertTina,
I'm not sure why you are so negative to having Excel in the mix.
Excel is only used at development time - its mearly used as a design interface to build the xcelsius model that feeds data and controls components within the flash file that xcelsius generates.
Excel is not used at run time in any way (unless one uses a third party connector to use an XLS as a data source of course).
If you attempt to use xceslius without using the OLE embeded Excel sheet at design time you will only be able to create VERY simplistic dashboards.
The new connectivity in version 4 just removes a design step to make development simpler my combining direct to components - but behind the sceens i believe it is really only connecting to a hidden part of the model not shown the the Excel interface at design time!
i think we would all agree that having excel can be a pain at design time (especially those that used/use live office!) but it does offer a pretty good interface for building very intuative looking models behind your flash components.
cheers,
Jeremy. -
Use different "fx-border-image-source" for first tab and remaining tabs
Hi,
I'm using something like this
.tab {
-fx-padding: 0px 5px -2px 5px;
-fx-background-insets: 0 -20 0 0;
-fx-background-color: transparent;
-fx-text-fill: #c4d8de;
-fx-border-image-source: url("images/tab5.png");
-fx-border-image-slice: 20 20 20 20 fill;
-fx-border-image-width: 20 20 20 20;
-fx-border-image-repeat: stretch;
-fx-font-size: 22px;
.tab:selected {
-fx-border-image-source: url("images/tab-selected5.png");
-fx-text-fill: #333333;
-fx-background-color: red;*/
to customize the tab appearance of a TabPane.
That worked well. But I need to use a different set of images for just the first tab. Does anyone know a way to accomplish that?
Thanks.How can I "fix up" the first tab of tab panes that are created after I "fixed up" the first tab of the initial tab pane?
My app allows user to create new tab panes at any moment during program execution.Not easy to answer this one.
The best answer would be to use structural pseudoclasses, but (as David points out), they are not yet implemented.
The trick here is how to identify the first tab of each tab pane so that it can be styled separately from the other panes.
Doing the styling without a dynamic lookup is preferrable to using a dynamic lookup (i.e. when the first tab is created give it a specific style, e.g. tab0).
This is how the charts work, where they set style classes based on series of data, e.g. series0, series1 - this allows you to independently style each series of data.
However the chart stuff has all of that built into the implementation, whereas the tabs don't. To achieve that you would likely need to go into the TabSkin code (http://openjdk.java.net/projects/openjfx/) find out where and how it generates the Tab nodes and write a custom tab skin or extension of the existing one which assigns a numeric style class to each new tab in a pane (e.g tab0, tab1, etc). In other words, not particularly easy if you are unfamilar with the tab skin implementation. You could log a javafx jira feature request to have those style classes set on tabs - file it here => http://javafx-jira.kenai.com.
In the meantime a simple alternative is to use the dynamic lookup method in my previous post and a hack such that whenever you add a new tab pane to the scene you do something like the following:
new Timeline(
new KeyFrame(
Duration.millis(50),
new EventHandler<ActionEvent>() {
@Override public void handle(ActionEvent arg0) {
Node tab = newTabPane.lookup(".tab");
if (tab != null) tab.getStyleClass().add("first-tab");
).play();The reason for the Timeline is that I don't really know at what stage the css layout pass is executed. I know that when you initially show the stage and then do a lookup, the css pass seems to have already been done and the lookup will work. But for something that is dynamically added or modified after the scene is displayed - I have no idea when the css layout pass occurs, other than it's some time in the future and not at the time that you add the tabPane to the scene. So, the Timeline introduces a short delay to (hopefully) give the css layout pass time to execute and allow the lookup to work (not return null). Not the best or most efficient solution, but should work for you. -
As many of you i suppose, i have a universal dock and a macbook pro.
Now because this dock and my MBP are often in the same room and both react to the remote, it would be handy if there was a widget which i could use to temporarily turn of my infrared port of the macbook, when i want to use my remote for the dock only.
If i only want to use the remote for my macbook it's simple, i just unplug my iphone, but if i want to do the opposite, use it only for my dock while working on the computer i have to complete several steps in the system preferences before i can get what i want.
So is there an easy way (i was thinking a widget in the dashboard) to get around this?
thx in advance for your thoughts!Unfortunetally, No and no. Apple TV is a closed API so developers are right now unable to create an app that is very compatible to connect to Apple TV. There is also no remote app on the Mac App Store.
Let me know if this solves your questions or if you have any others,
Thanks,
Allen
