Interface with a protected modifier

Can we have an interface with a protected modifier?
For I am getting an error
protected modifoer not allowed
Are there any conditions where we cannot have any protected modifiers?

Interfaces are public. For more information about interfaces please read Java Language Specification.

Developing a User Interface with ADF Faces - Tutorial - Questions

Hello everybody,
I am a forms developer and I am totally new to ADF.
I started from the tutorials : Developing Business Services with ADF BC and Developing a User Interface with ADF Faces...
Everything was easy and very clear, as far as the material covered in the tutorial is concerened.
But when I tried to modify a little bit the application, to perform a different task... disaster!!! :-)
One of the "simple" things that I tried to do -for example- is :
In the login.jspx, where we have created an ADF Parameter form (that accepts as a parameter the customer ID) and
retrieves in the next page the Orders of the specific customer.... to Display a message, such as "+Customer Does Not Exist+"
if the user types in the parameter form an not existent customer ID...
I understand that I should use a validator.... But I cannot find the list validator (from query) in the bind variables not in the ADF Parameter Form Fields....
Does anyone know?
Regards,
Maira Kotsovoulou

Dear Grant,
CustomerID is in the UI Project, and appears as a part of an ADF Parameter Form... and I can not find key exists in the UI Validators....
CustomerID in the .entities is a bind variable in a query. select ... from customers where customer_id = :p_customer_id. Again KEYEXISTS validator is not available in the bind variables sections... Only in the attributes!!!
I understand that the "normal" behavior in a query with bind variables where there is no match is to display nothing as it does!!!
But I was just wondering, if I could even trap that before I display the empty form...? Or could I display a text in my ADF form, that says no rows... (as I can do in an ADF Table???)

JavaBeans can interface with OpenOffice

Hi, I ask you another question: any of you have created or used a JavaBeans can interface with OpenOffice??
I modified the java classes and finally managed to create a document. Odt OpenOffice Writer and launch from Eclipse. If I am not using the libraries oooBeans but there are 2 problems now:
1. For known issues I had to set the Java class path of the folder where you have OpenOffice executables and should be changed ...
2. I created a. Jar file executable, but I do not know how to integrate Oracle Forms and use it as JavaBeans. Perhaps this step you're more prepared

Yes, you'll find the companion app SDK in the normal Photoshop SDK.

Warner/superior electric's SS2000PCi motion controller interfacing with LabVIEW 6i

Sir,
In our application, we are controlling the movement of X-Y arm on the X-Y table. For this we are using superior electric products:
(a) Slo-Syn SS2000PCi Programmable Step Motor Controller
(b) MD808 Motor Drive
We are using two such controllers and motor drives to drive two 2 Amps Sanyo Denki Stepper motors: one each along X-axis and Y-axis. Along with the arm movement a data acquisition also has to be carried out. So, the motion control and Data Acquisition has to be synchronized by means of software. The problem now is to program the controller. Though MCPI Version 4.41 is there, we want to program the controller in LabVIEW 6i so that we can synch
ronize both motion control and Data Acquisition.There is no driver which is compatible to LabVIEW 6i.
Is there any 32-bit DLLs for this controller? If any one has these dll's please let me know. My E-mail ID: [email protected]
So that i can call these DLLs in LabVIEW 6i and program it.Or else send me at least the detailed low level command sets of the controller in pdf format so that i can develop our own drivers.
Regards,
Nagendra

Nagendra,
Unfortunately, I was unable to find any helpful resources for you based on a cursory web search. I recommend that you contact the manufacturer of the hardware and ask them if they have a driver (DLL) that you can use to interface with LabVIEW.
Good luck with your application, and have a good day.
Sincerely,
Darren N.

Spry with DW insert, modify and delete behaviors

I posted this question before and didn't get a response. I'm
wondering if there is any documentation available for using Spry
with DW insert, modify and delete behaviors? I'd like to be able to
perform these functions without having to go from list to master to
detail page as in traditional ASP etc. According to Alex July at
Linecraft this is one of "many hidden features" in Spry.

Here you can find an article that covers data update:

The server-side code is CFML, but the concept is the same.
A more complete demo, with search, insert, update and delete
is available

Multiple interfaces with same IP address?

Can anyone suggest how to configure multiple (logical or physical) interfaces with the same IP address?
There is a teaser in the solaris 8 man page for 'route' that suggests this is possible:
"In a change or add command where the destination and gateway are not sufficient to specify the route (for example, , when several interfaces have the same address), the -ifp or -ifa modifiers may be used to determine the interface or interface address."
I can find no other reference to -ifp or -ifa, and at the moment I cannot seem to bring up two interfaces (logical or physical) with the same ip address.
I realise this is an obscure config. Anyone intimately familiar with route of ifconfig?
AJB

Yes. I could have laid odds that this would be the first response :-)
I know it is unusual, and I am aware of the inherent issues with doing something like this. I have read the multipathing guide, but it wasn't that helpful, because I want the same IP address, not just the same subnet. It is NOT for load balancing, or failover support. I'm afraid I can't give too much detail at the moment because of the nature of research project. What I will add is that I want to do this on an 802.1q enabled NIC, on the same physical port, with different logical interfaces for each VLAN having the SAME IP address.
We can already do this on Linux, and as I said in the original post, the route man page suggests that it can probably be done on Solaris. What I really need to know is how?
Any takers?

Are there any third party pacakages for plant maintenance that can be interfaced with

are there any third party plant maintenance packages that interface with OPM? does Oracle apps have a module for plant maintenance?

I'm working for a leading Food Industry in Kuwait (The Kuwaiti Danish Dairy Co.) We have a massive implementation of OPM with 24 modules, BI tools (OSA, OFA) and Maximo (The only third party package) integrated with Oracle. OPM version is 11.0.3 on database 8.0.5. Now you have option of 11i (eAM) with POC (PM) or Maximo 5i integrated with 11i (and of course any other 3rd party solution which can be integrated with OPM).
You can write to me on: [email protected] or call me on: +965-9650172 for details.
All the best.

Database design to support parameterised interface with MS Excel

Hi, I am a novice user of SQL Server and would like some advice on how to solve a problem I have. (I hope I have chosen the correct forum to post this question)
I have created a SQL Server 2012 database that comprises approx 10 base tables, with a further 40+ views that either summarise the base table data in various ways, or build upon other views to create more complex data sets (upto 4 levels of view).
I then use EXCEL to create a dashboard that has multiple pivot table data connections to the various views.
The users can then use standard excel features - slicers etc to interrogate the various metrics.
The underlying database holds a single days worth of information, but I would like to extend this to cover multiple days worth of data, with the excel spreadsheet having a cell that defines the date for which information is to
be retrieved.(The underlying data tables would need to be extended to have a date field)
I can see how the excel connection string can be modified to filter the results such that a column value matches the date field,
but how can this date value be passed down through all the views to ensure that information from base tables is restricted for the specied date, rather than the final results set being passed back to excel - I would rather not have the server resolve the views
for the complete data set.
I considered parameterisation of views, but I dont believe views support parameters, I also considered stored procedures, but I dont believe that stored procedures allow result sets to be used as pseudo tables.
What other options do I have, or have I failed to grasp the way SQL server creates its execution plans and simply having the filter at the top level will ensure the result set is minimised at the lower level? (I dont really want the time taken for the dashboard
refresh to increase - it currently takes approx 45 seconds following SQL Server Engine Tuning Advisor recommendations)
As an example of 3 of the views,
Table A has a row per system event (30,000+ per day), each event having an identity, a TYPE eg Arrival or Departure, with a time of event, and a planned time for the event (a specified identity will have a sequence of Arrival and Departure events)
View A compares seperate rows to determine how long between the Arrival and Departure events for an identity
View B compares seperate rows to determine how long between planned Arrival and Departure events for an identity
View C uses View A and view B to provide the variance between actual and planned
Excel dashboard has graphs showing information retrieved from Views A, B and C. The dashboard is only likely to need to query a single days worth of information.
Thanks for your time.

You are posting in the database design forum but it seems to me that you have 2 separate but highly dependent issues - neither of which is really database design related at this point. Rather you have an user interface issue and an database programmability
issue. Those I cannot really address since much of that discussion requires knowledge of your users, how they interface with the database, what they use the data for, etc. In addition, it seems that Excel is the primary interface for your users
- so it may be that you should post your question to an excel forum.
However, I do have some comments. First, views based on views is generally a bad approach. Absent the intention of indexing (i.e., materializing) the views, the db engine does nothing different for a view than it does for any ad-hoc query.
Unfortunately, the additional layering of logic can impede the effectiveness of the optimizer. The more complex your views become and the deeper the layering, the greater the chance that you befuddle the optimizer.
I would rather not have the server resolve the views for the complete data set
I don't understand the above statement but it scares me. IMO, you DO want the server to do as much work as possible since it is closest to the data and has (or should have) the resources to access and manipulate the data and generate the desired
results. You DON'T want to move all the raw data involved in a query over the network and into the client machine's storage (memory or disk) and then attempt to compute the desired values.
I considered parameterisation of views, but I dont believe views support parameters, I also considered stored procedures, but I dont believe that stored procedures allow result sets to be used as pseudo tables.
Correct on the first point, though there is such a thing as a TVF which is similar in effect. Before you go down that path, let's address the second statement. I don't understand that last bit about "used as pseudo tables" but that sounds more
like an Excel issue (or maybe an assumption). You can execute a stored procedure and use/access the resultset of this procedure in Excel, so I'm not certain what your concern is. User simplicity perhaps? Maybe just a terminology issue? Stored
procedures are something I would highly encourage for a number of reasons. Since you refer to pivoting specifically, I'll point out that sql server natively supports that function (though perhaps not in the same way/degree Excel does). It
is rather complex tsql - and this is one reason to advocate for stored procedures. Separate the structure of the raw data from the user.
(I dont really want the time taken for the dashboard refresh to increase - it currently takes approx 45 seconds following SQL Server Engine Tuning Advisor recommendations)
DTA has its limitations. What it doesn't do is evaluate the "model" - which is where you might have more significant issues. Tuning your queries and indexing your tables will only go so far to compensate for a poorly designed schema (not that
yours is - just a generalization). I did want to point out that your refresh process involves many factors - the time to generate a resultset in the server (including plan compilation, loading the data from disk, etc.), transmitting that data over the
network, receiving and storing the resultset in the client application, manipulating the resultset into the desired form/format), and then updating the display. Given that, you need to know how much time is spent in each part of that process - no sense
wasting time optimizing the smallest time consumer.
So now to your sample table - Table A. First, I'll give you my opinion of a flawed approach. Your table records separate facts about an entity as multiple rows. Such an approach is generally a schema issue for a number of reasons.
It requires that you outer join in some fashion to get all the information about one thing into a single row - that is why you have a view to compare rows and generate a time interval between arrival and departure. I'll take this a step further and assume
that your schema/code likely has an assumption built into it - specifically that a "thing" will have no more than 2 rows and that there will only be one row with type "arrival" and one row with type "departure". Violate that assumption and things begin to
fall apart.  If you have control over this schema, then I suggest you consider changing it. Store all the facts about a single entity in a single row.  Given the frequency that I see this pattern, I'll guess that you
cannot. So let's move on.
30 thousand rows is tiny, so your current volume is negligible. You still need to optimize your tables based on usage, so you need to address that first. How is the data populated currently? Is it done once as a batch?  Is it
done throughout the day - and in what fashion (inserts vs updates vs deletes)? You only store one day of data - so how do you accomplish that specifically?  Do you purge all data overnight and re-populate? What indexes
have you defined? Do all tables have a clustered index or are some (most?) of them heaps?   OTOH, I'm going to guess that the database is at most a minimal issue now and that most of your concerns are better addressed at the user interface
and how it accesses your database. Perhaps now is a good time to step back and reconsider your approach to providing information to the users. Perhaps there is a better solution - but that requires an understanding of your users, the skillset of
everyone involved, what you have to work with, etc. Maybe just some advanced excel training? I can't really say and it might be a better question for a different forum.
One last comment - "identity" has a special meaning in sql server (and most database engines I'm guessing). So when you refer to identity, do you refer to an identity column or the logical identity (i.e., natural key) for the "thing" that Table A is
attempting to model?

Will somebody provide me with a QBASIC 4.5 PROGRAM for Interfacing with an Anritsu make(model-MS710) RFspectrum analyser through GPIB ( NI-488.2 ) in DOS environment? I would like to aquire data from the instrument and save it in PC for printing purpose.

Hello,
Unfortunately I was unable to find a driver for this instrument. This leaves you with one of a couple options. First, I would like you to submit a request for this driver at:
http://www.ni.com/devzone/idnet/other.htm
We develop drivers in CVI and LabVIEW based on demand and popularity so the more requests we have for it, the greater the possibility that we will develop one. While this would not provide you with a QBASIC program, you may be able to create a DLL that you could call from QBASIC.
If you would like to try developing your own instrument driver (or modify the existing one), we have documentation, model instrument drivers, and driver templates to help at :
http://www.ni.com/devzone/idnet/development.htm
We also have a syndica
te of third party vendors that specialize in National Instruments' products and services. Some of the vendors specialize in driver development. I would suggest contacting one of the Alliance members at:

Creating local interfaces with JDeveloper (release 2)

Hi
Maybe I'm missing something here, but how does one create a local- and a local-home interface with JDeveloper? It only seems to give me the option to create a remote- and a home interface.
I've tried creating the local interfaces by hand and then adding them as <ejb-local-ref> references in the ejb-jar.xml deployment descriptor, but I get the message "local/local-home tag not supported in this version" when trying to test the code with the Embedded OC4J Server.
Now, I've managed to create EJB 2.0-style CMP entity beans by modifying the code and deployment descriptors a little, which made me believe that EJB 2.0 is supported, but that seems to be where it stops.
Am I doing something wrong, or is EJB 2.0 not fully implemented in the Embedded OC4J Server yet?
Hope you can help
Christof

JDeveloper 9.0.2 doesn't have support for local interfaces or any EJB 2.0 features.
Next release of JDeveloper (9.0.3) will have complete support of J2EE 1.3 features including EJB 2.0.
This release is slated for this summer (2002)

Using Digi 003 interface with Logic Studio or Pro

I currently have a modified (Black Lion Audio) Digi 003 Rack interface that I use with Pro Tools, but would like to get Logic Studio (or Pro). I have heard 50% say that the Digi 003R or Mixer won't work (properly) with Logic and I have heard another 50% say that it works fine. Can somebody please end this debate once and for all, so I can make the big $500-$1000 decision. I'm really itching to get Logic so I can use all of its great features. I would like to hear that it works fine, but if not, I'd rather know the facts before wasting my money. Thank you to anybody who can put this question to rest.

Lets clear up some things - Logic Studio comes with Logic Pro. . . so that's $500. Logic Pro 7 is old and you don't need it anymore, it WAS $1000. So, no need to spend a grand on Logic.
Next, 003R works absolutely fine as an interface with Logic. The mixer won't work as a control surface (although it will work fine as an interface) because Digi's control surface stuff is proprietary and isn't made to work with Logic.
So, to sum up - Logic Studio is Logic Pro 8 and a ton of other apps and its only $500.
003 Rack works fine with Logic.

Why interfaces cant be protected

Let's assume for a moment you can have a protected method in an interface.
That would mean that that method MUST be implemented by something that EXTENDS that interface.
Only interfaces can EXTEND other interfaces.
Any class implementing the interface would have to be abstract as it cannot implement the function (it can't even see it after all, as it's protected and thus visible only to things that extend the interface, not to things that implement it).
Any class subclassing your implementing class cannot be anything other than abstract either of course as it also cannot see the protected method and thus cannot implement it.
You've now created an entire class tree of abstract classes with no way to ever get an instance of one, hardly useful.
Even a static method of one of those classes (which you could call) would be unable to use the protected method as it's never implemented and anyway invisible to anything except the interface and any subinterfaces themselves (which the class is definitely not).

How do I use an audio interface with iMovie?

I'm trying to shoot a short clip of a musician playing. I want to use an interface with my higher end mics, and use iMovie '09 to shoot video. I have a Presonus Firebox as my interface. iMovie just doesn't seem to want to recognize it, nor record through it. This isn't something I can share to GarageBand because the timing between the video and audio has to be perfect. Any help?
Thanks

Just buy the proper adapter cord, such as MiniDisplay port to HDMI for example. Plug it in and it will be automatically recognized. Use System Preferences > Displays to set options.
The display can Mirror your primary desktop or Extend the Desktop.
