Question about using Forms in a special project or not

Hi,
We have a project which must be available via internet. The estimated users of this application, in worth case, can be something about 2000. All users belong to a company but are distributed around the country.
All the development team in our company know Forms Builder (up to 10g) and have several years experience in using that in different projects. Two of our developers know APEX and non of us knows java and ADF.
My question is that is it really possible to develop such an application using Forms? Can we just use APEX for that? or we have to jump into Jdeveloper and ADF? Please look at the problem from all aspects if you would like to guide me. What i mean is that if you say we have to use java and ADF, then learning of these is a seperate project itself and we don't have a large time window for project. The budjet of project is also a serious thing.
Thanks in advance,
Alireza Vali

2000 concurrent sessions...now that would require quite a big application server farm if you are using forms for this project. As you have experience in PL/SQL and none in Java/ADF the decision shouldn't be that hard. Java is an Object Oriented language whereas PL/SQL is procedural which means quite different ways of doing things when you e.g. want to write APIs. If you don't have any expierience in any Object Oriented language starting off with a quite big project in java might not be a good idea. This doesn't mean that you shouldn't learn java at all, but when learning a new language you usually start with a "Hello World" application, and not with writing a operating system with that language.
APEX on the other hand is plain PL/SQL and not just for small websites; a good sample is the asktom site; it is written in APEX and I guess it has a fair amount of traffic.
So APEX has some benefits
- you have already knowledge in house
- you are familiar with the language
- APEX doesn't require an application server license; you can use oracle XE and if you don't want to expose the database to the www use a plain apache server to handle the http request
So if it were me, APEX would be the way to go.
cheers

Question about using the JBIBRIDGE in MIDM project

I am in the process of implementing the ESB based MIDM. I am trying to use a JBIBridge in the process. I have 3 different projects that need to the PersonEJB in their JCD's. The question is do I use the same JBIBridge External Application in each of the connection maps? Then do I deploy those JBIBridges to the same JBIBRIDGE External System and add each of thos 3 deployment Profiles to the same Composite Application? Or do you create three seperate JBIBridge External Applications, Systems and Composite Application?

Regarding calls when roaming internationally, the following was copied from this link.
http://www.wireless.att.com/learn/international/roaming/faq.jsp
When your device is on:
Calls that you do not answer that are routed to the AT&T voicemail system will be charged as an international roaming incoming call to your device.
In addition, the foreign carrier's routing of that call to the AT&T voicemail system may generate an outgoing call charge from your device's location to the U.S.
These charges apply even if the caller disconnects from the voicemail system without leaving a message.

Question about using Forms Central for making fillable school worksheets

Can Forms Central be used to create (fillable) school worksheets for my son, that he can then open and type responces to? That is the only thing I need it for. For instance, I would like to make worksheets for spelling that would ask him to type certain spellings words (from a list) where long a is spelled ai, et cetera.

Sure - that sound like a very achievable form to create using FormsCentral. You can/should give it a try by creating a free account and either creating a new form from "blank" (new custom form) or starting with a related Template you would modify. You can see if it would work for you, you can have one form at a time in your free account, you can always delete the one you try out and then try another.
Thanks,
Josh

I have a question about using multiple ipads in our school. Each of our teachers have a iPad and AppleTV in their classroom. The issue is, with our classrooms so close in proximity to one another, is there a way to pair teacher

I have a question about using multiple ipads in our school. Each of our teachers have a iPad and AppleTV in their classroom. The issue is, with our classrooms so close in proximity to one another, is there a way to pair teacher #1 iPad to its AppleTV without effecting/projecting onto the adjacent teachers #2 classroom AppleTV?

Not as such.
Give the AppleTV units unique names and also enable Airplay password in settings with unique passwords for each teacher.

Question about Using PAPI Web Service in PowerBuilder 9

Hi, all.
I Have a simple question about using papiws in power builder 9.
In pb9, I created a new Web Service Proxy Wizard and I input a url for papiws(ex. http://seraphpernote:7001/papiws/PapiWebService) and click next.
But I couldn't get any Service List.
In Eclipse, I used this url for using papiws well.
Does anybody know about this case??
help me plz.

IIRC you must activate PAPI-WS for the engine. In Studio you do it by right-clicking on the project, then "engine preferences". In enterprise/standalone you must activate PAPI-WS in the Admin Center.

Few common questions about Mobile Forms

Hello, everyone!
I have a few questions about mobile forms:
Can a form be integrated with a portal, which is build NOT on Adobe CQ\AEM technology?
I've created a form and loaded it to the server repository via Form Manager. Now I can access it in my browser like this:
http://testlcserver:8080/lc/content/xfaforms/profiles/hrform.html?contentRoot=repository%3 A%2F%2F%2FApplications%2FTest%2F1.0&template=UberForm.xdp&dataRef=
And the question is: what is the right way to share forms to users on a production environment (without integration in a portal pages on so on, let it be just a link to a form which users have to fill in)? I mean, should it be the same link, or it is only for developers need and to share forms to users some other way must be used?

For integrating on custom portal, you would need to integrate with form submit proxy for handling of submission as mentioned @ http://helpx.adobe.com/livecycle/help/mobile-forms/mobile-forms-service-proxy.html.
As far as url of form is concerned, it’s really up you. You can choose to hide the request parameters as couple of other customers are doing. You can find more information about hiding form template and content root from request parameter @ http://blogs.adobe.com/foxes/hide-parameters-from-mobile-form-url/

Hi, I have quick question about use of USEBEAN tag in SP2. When I specify a scope of SESSION for the java bean, it does not keep the values that I set for variable in the bean persistent.Thanks,Sonny

Make sure that your bean is implementing the serializable interface and that
you are accessing the bean from the session with the same name.

Question about using new battery in old Powerbook

I have a pre-intel Powerbook G4, and the battery is pretty much toast (lasts about 15 minutes now). I have ordered a new battery for it, and I have this question about using it:
Am I smarter to keep the new strong battery out of the PB most days (as I usually work with it plugged in at home) and just pop it in when I know I will be out surfing on batteries? Or is it just as good living in my laptop 24/7 and only occasionally being called upon to do its job?
Current bad Battery Information below:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 1144
Remaining Capacity (mAh): 1115
Amperage (mA): 0
Voltage (mV): 12387
Cycle Count: 281
thanks folks, Shereen

Hi, Shereen. Every Powerbook battery wants to be used — drained and then recharged — at least every couple of weeks. If you've always used your Powerbook on AC power nearly all the time, and not followed that pattern of discharging and recharging the battery every week or two, it's possible that your use habits have shortened the lifespan and prematurely diminished the capacity of your old battery. Of course it's also possible that your battery is merely old, as a battery's capacity also diminishes with age regardless of how it's used. You didn't say how old the battery is in years, so this may or may not be an issue. I mention it only because it can be an issue.
For general information on handling a battery for the longest possible lifespan, see this article. My advice on the basis of that article and long experience reading these forums is that it would be OK to do as you propose, but I doubt that you'd derive any significant benefit from it. You would still want to be sure of putting the new battery through a charge/discharge cycle every week or two, even if you didn't have a reason to use the Powerbook away from home or your desk, because sitting unused outside the computer is just as bad for a battery as sitting unused inside it. And you should never remove the battery from your computer when it's completely or almost completely discharged and let it sit that way any longer than a day or two.

Question about using TVARV in an ABAP program

Hello gurus, Im sorry about the silly question.
I have a question about using TVARV in an ABAP program.
A program is presenting a problem and I think that in this code:
SELECT SIGN OPTI LOW HIGH
FROM TVARV
INTO TABLE R_1_163431035_VELOCIDADE
WHERE NAME = '1_163431035_VELOCIDADE'
AND    TYPE = 'S'.
IF ZMM001-VELOCIDADE_B   IN R_1_163431035_VELOCIDADE AND
      ZOPERADORAS-OPERADORA = 'ABCD' AND
      ZMM001-MATERIAL       IN R_1_163431035_PRODUTO.
ELSE.
ENDIF.
What happens is that the value "ZMM001-SPEED" B not exist in "R1_163431035_VELOCIDADE" but the program executes commands under the IF and not under the ELSE, as I imagine it would work. Is this correct ?
I am new to ABAP programming, but I have a lot of XP in other programming languages and this makes no sense to me.
Anyone know where I can find some documentation of the use of "TVARV" in ABAP programs?
I search the Internet if other programmers use TVARV this way, but found nothing, which leads me to think that was a quick and dirty solution that used here.
If this is a bad way to program, what would be the best way?
Regards
Ronaldo.

Hi Ronaldo,
But in this case, the range is not empty, there are 17 records, in this way.:
For the column "SING" all values are "E"
It means that the result is false if ZMM001-VELOCIDADE_B has the same value as one of the 17 records (E = exclude).
For instance, if it has value 'C' and one of 17 records matches C, then the result is false.
The "IF" with "IN" using "TVARV" as used in the program of the post above has the same behavior of a selection screen?
Yes, the same behavior as the selection criterion to be exact. You can press the help key in the complex selection dialog for more info.
I know it's a silly and very basic question, but other language that I used, only the SQL has the "IN" operator, but I think they work in different ways, so I would like to understand how it works in ABAP.
Not silly ;-). Yes they work differently.

Question about using 10g/11g and APEX ...

Hi,
I just recently learned of Oracle's APEX and have a few questions about using it.
Can I use APEX with express, standard, and enterprise editions of 10g and 11g?
Are all of these free to use?

You might want to read about APEX rather than jumping into questions that are reasonably well documented. Info at http://www.oracle.com/technology/products/database/application_express/index.html
Your specific questions:
1) Apex is a package that can be installed into any properly licensed database.
2) The price for the production license of the database varies by edition.
The price for Express Edition is $0 for use in production. Part of the cost for that edition is 'no Oracle Support based support, no patches, data volume limitation, etc.'

Question about using Runtime.getRuntime();

hi all
i have a question about using Runtime.getRuntime(). if i use this to get a runtime reference to run an external program, is it considered as starting a new thread inside the thread that starts it?
is it safe to do it in the Session EJB? if not, what can you recommand to do it? thanks

hi all
i have a question about using Runtime.getRuntime().
if i use this to get a runtime reference to run an
external program, is it considered as starting a new
thread inside the thread that starts it? No. Starting a process, starts a process. Threads have nothing to do with it.
is it safe to do it in the Session EJB? if not, what
can you recommand to do it? thanksSo what? Run another process? If you want to run another process in java then your choices are to use Runtime.exec() or use JNI. And using JNI will probably end up doing exactly the same thing as Runtime.exec().
"Safe" is harder. Typically to correctly use Runtime.exec() you must use threads. And as noted threads ideally should not be used. You can use them but if you do you had better understand why they didn't want you using them in the first place. You had also better be sure that you really want to wait for it to complete.
Other than that Runtime.exec() is safe because it can't crash the VM like other interfaces can (like JNI.)

Questions about using a PDF form online

I have a client who wants to create an online version of a PDF form that they are currently using. I am currently trying to explain to them that this would be best done as an HTML web form, but I may not win this argument. I have only used PDFs for printed forms (either hand-written or using form fields) so I am not familiar with any problems that converting the form for use online would entail.
When the 'Submit' button is pressed on the form, is there a way to redirect to another web page after the data is submitted? (i.e. does the PDF have access to it's outer 'environment'?)
Are there any security issues submitting data using the PDF form as opposed to using a standard web form? (There may be sensitive data being submitted)
I'm not sure how they plan to handle the data that is submitted, but there are several options in the submitForm parameters - I am assuming that using the HTML option would submit the data in the same format as a web form would. Am I correct here?
Can the PDF be prevented from being downloaded or printed? This form should only be used to submit data to their server, not as a printed form.
Are there any other 'gotchas' that I need to look out for? Does anyone have a recommendation for a site which contains any tutorials or guidelines for using PDF forms online?

Thanks for the information.
Yes, I agree that there is less reason for it to be a PDF form (Actually, no real reason other than the original form already exists in PDF), but I am unfortunately in the position that my input in this project is not necessarily being considered (my company is following direct -and inconsistent- directions from the client, and I have no contact with the client to ask questions about what their actual needs are). I have been told to give the client the 'Tomato' that they are asking for, even though they are describing an 'Apple'.
The reason this form is not meant to be printed is that we have replaced the 'Signature' fields from the original form with checkboxes that the user must check to confirm they have 'signed' the document. If they are to print/fax/whatever the document, they should use the original form, not this one. And I am still trying to explain to them that this would be better served with an HTML web form, but I fear I am losing that battle.
I have brought up the fact that it is not 100% guaranteed that Acrobat will be available in the browser, although I can only guess that it is less than likely that anyone will not have some sort of PDF viewer available to their browser.
I will also mention that issues may arise if the file is not submitted from within the browser.
