Offline Mobile PDA application

We are looking to develop an oracle mobile application on PDA's so that data can be entered offline and then later this data synchronized with the main db. After a brief look at Oracle lite docs it seems this may be the answer. As a newbie to both oracle lite and PDA technologies I am trying to determine what application languages we could use. Can oracle forms be used with Oracle lite on PDA's? I've also been looking into HTMLDB for other reasons can this somehow be put onto PDA with Oracle lite? Any suggestions as to application languages would be of much help.

Your best bet is probably .Net and then Java.

Thanks.

You could turn on debugging for your EJB's. Add the following tag to your OC4J start options:
-Dejb.debug=true.
Please also check the following logs:
- $OH\application-deployments\<appName>\OC4J_Namedefault_island_1\application.log
- the opmn logs for your OC4J instance
Furthermore you can add some Sys.out statements to your code to see where the problem lies.
Hope this helps.

High CPU usage with LabVIEW Mobile (PDA)

I just started my first LV mobile (PDA) application and I should be doing something incorrectly. I used a producer/consumer (events) architecture in my first attempt. The only thing my VI has is a stop button that made the app stop; nothing else. When I ran it in the pda it was using between 95 and 100% of the CPU time. I’m aware of, and planning in using, the recomendations about memory usage, buffer allocation, etc. but at this point my app does not have anything but two for loops running in parallel; one of them with the event structure. I wonder if there is any particular framework that is better for mobile apps.I used the default values in the builder to create the executable. My executable was made with LV 8.6, mobile module 8.6 (trial mode) and the PDA is running windows mobile 6.1 Any adivice that helps me understand why a very simple app is soooo cpu hungry will be highly appreciated.

I think this is a very good question. Have you solved the problem?

Existing tools to develop mobile applications( mobile,pda,removable media)

hi java developers,
could anyone answer the question that are asked below
1) what are the existing tools to develop mobile based applications( ex: mobiles, pda , laptop, pocket pc's,smart phones, and removable media )
2)what are the encryption methods present& how to secure communication of files and documents?
awaiting for reply...
thanking you,
vemuri...

this reply is based on what I know,
for mobile I use : Sun's Wireless toolkit , netbeans with mobility pack (best acc ording to me).
for secure data communication: you can use secure server and client sockets, by which you can make your files and documents travel securely between client and server in encrypted form using the personal and public keys.

Run Mobile Infrastructure application(7.0) PDA

Hi
I have developed mobile infrastructure application.Now i want to run that application on PDA.
Please also tell me steps for running application on PDA.
Also give me some link for downloading

Hi,
so you are developing for MI7.1?In that case you have emulator available. Download the SAP Dev Studio first, then add the mobile addOns. The process is described here:
http://help.sap.com/saphelp_nwmobile71/helpdata/en/dd/9427535e5040faa26aa0afd6f0bf87/frameset.htm
and after that, you need to follow the guide here as well:
http://help.sap.com/saphelp_nwmobile71/helpdata/en/45/c9daf9f55c5590e10000000a1553f7/frameset.htm
It is a little bit of a handy process, but once you have done it, the emulator is available under settings -> Mobile -> PDA runtime and you can start it there.
Ths guide shows you as well how to develop apps for mobile.
Hope that helps.
If you deal with MI7.0 - unfortunately there is no emulator and you need to follow pretty much the steps mentioned above.
Regards,
Oliver

How to remove focus from a Ring Control in a PDA application?

Hello,
In a PDA application, i have observed that when we select a pull-down Ring control, the focus is retained in the control and the text of the control appears highlighted. The only way out is to tap an empty portion of the PDA application screen to remove focus from the control. Is there any way to avoid this? Is there a method to remove focus from the control programatically?
Note: Version of LabVIEW that we are using: LabVIEW 8.5 Professional Development System for Windows Vista/XP/2000 and LabVIEW 8.5 PDA Module for Windows Mobile.
Thanks & Regards,
Subhashini

Hi Vsh,
Thanks for ur response. Setting the key focus property node of the ring control to false removed the focus from the control. I guess it was a silly question (have started LabVIEW devp. recently).
Thanks & Regards,
Subhashini

Mobile Phone Application

HI All, Thanks for reading!
I am looking to create an application for my mobile, similar to HANDY apps (to collate info, etc)...
It would be basically something to help me keep record of gym work...
question is, how would i approach this - what would be the best tools to use?
Appreciate ANY help...
Danny

short answer:J2ME
longest answer (I can thing write now): basically this is the package you have to use when developing applications for mobile, pda's etc. There is not much to say about it all, download it and use it, try finding an emulator, you should find one as well for free.

Tutorial for Building Mobile Web Applications Using ADF/BC4J-problem

This is the tutorial for:
Develop a offline, Web-based Disconnected Mobile application
Trying to create an offline mobile application using jdeveloper & oracle lite. I want to be able to update the home database after using the application in a disconnected fashion. I do not have a web site, nor is that a feasible option.
Jdeveloper 10.1.3.4 which should be OK as it is higher than the release specified in the tutorial.
webtogo
oraclie lite 10
oracle 10.
I have tried to follow the tutorial completely and I can not get this to connect from webtogo. It runs fine in the jdeveloper usising the container. I created the war file, did the wtg packaging process, opened the mobile manager and published the application & granted access to user 'john'. The samples provided work fine. The new application appears on the webscreen after installing web 0c4j. When I click on it, the address toolbar shows:
http://localhost/webtogo/bc4jtutorial/faces/CustomerOrders.jsp
When it installed mobile client, it installed the CustomerOrders.jsp into:
E:\mobileclient\mobile_client_oc4j\j2ee\mobileclient\applications\mobileclient\bc4jtutorial
an example of the samples that work shows
http://localhost/webtogo/sample6/list
in the browser address line.
Which looks like it's really
E:\mobileclient\mobile_client_oc4j\j2ee\mobileclient\applications\mobileclient\samples\sample6
on the file system
Any one have any ideas? I'll take another solution if someone has found one. However, i am not a great java programmer so thought jdeveloper was great to create forms and access the database.

Hi,
selecting a session bean, this option shows for me in 11.1.2. Make sure that - by accident - you don't select the local or remote interface class

Using database views in ADF mobile client application

Hi,
I am using Jdeveloper 11.1.1.4 and WLS 10.3.4.
I have developed a POC in ADF mobile client application both with and without synchronization. However, both work with entity objects based on tables.
I need to use database views instead of tables. When I try to include entity object (based on views) in the view object, it shows an error saying "Only the entity objects based on tables can be selected"
Please guide me if there is a work around for this.
Also, please let me know if there is way to develop an ADF mobile client application skipping the use of entity objects at all and using view objects directly to specify the database query and fetch data from the database.
Thanks in advance.

Hi, Ansh:
Currently, out of box, ADF Mobile Client does not support synchronization against Database Views. This is because Mobile Server imposes some schema restrictions to ensure synchronization with multi-table views would work correctly. This schema restriction requires, for example, the view must have a primary parent table with key defined, and also all base table must be included in the data publication. These dependencies requires manual resolution and advanced planning, and is managed outside of the ADF Mobile Client/JDeveloper project.
To continue development, you would need to create server Entity Objects directly against the base tables. You can then create the mobile ADF Business Component (EOs, VOs, etc). You can then create View Objects in your ADF Mobile Client application based on the database views, in order to retrieve the data you need exactly. In other words, instead of basing EO on the database view, create View Objects in the mobile applicaiton to mimic what you had in the View Object.
Is there any other reason why you would need to access data via database views, instead of directly against base tables?
Thanks,
Joe Huang

After installing the 64 bit version of itunes my iphone still won't sync. I get the explantation that I mobile driver application did not download and i need to remove and reinstall itunes (which I have done numberous times). Any help?

After installing the 64 bit version of itunes my iphone still won't sync. I get the explantation that I mobile driver application did not download and i need to remove and reinstall itunes (which I have done numberous times). Any help?

Let's try a standalone Apple Mobile Device Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of why it's not installing under normal conditions.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleMobileDeviceSupport.msi (or AppleMobileDeviceSupport64.msi) to do a standalone AMDS install.
(If it offers you the choice to remove or repair, choose "Remove", and if the uninstall goes through successfully, see if you can reinstall by doubleclicking the AppleMobileDeviceSupport.msi again.)
Does it install (or uninstall and then reinstall) properly for you? If so, does your device connect without that message now?

PDA Application Connect to Database

Hi,
I want to develop application sit on PDA(like iPAQ) eg.Contact Manager (to keep personal contact). this require a database to keep all these information in the PDA so that can be retrieve.
Its there any Micro-Database that can be installed into PDA (free?).
Please show me the link to get this Installaler, JDBC and documentation.
Please show me also the way to create database and table in PDA. and step to install this micro-db into the PDA.
It would be more helpful, if someone can give me some simple example of a PDA Application connect to Database.
Thanks in advance, Regards

Open source one is :
http://sourceforge.net/projects/hsqldb
This one is not absolute free but the price is quite compelling.$995 for unlimited install.
http://www.quadcap.com/home.html
http://www.quadcap.com/purchase/index.html
4. The rights granted pursuant to this Agreement are contingent upon Licensee's payment of the license fees for the QED Software. The License Fee for this Commercial Redistribution License is USD $995.
Even SQL CE from MS is free, as long as you not use it connected to backend system. so if u could work out other sync implementation or u dont need data sync at all, this might be a choice too. The issue is no official JDBC driver for SQL CE though there is for SQL server.
However, I have no hand on experience on those 3. We are evaluating Pointbase Micro, thought not free.l

JBO-27122 error in ADF mobile client application for blackberry

Hi,
I am trying to develop a simple ADF mobile client application for blackberry. Currently, working only with Blackberry 9700 simulator. I am using the following for development:
- Jdev 11.1.1.3
- Oracle database lite 10.3.3
I have done all the steps as given in the oracle demo. But when I try to run the application in blackberry simulator, the page shows the following error:
ERROR: failed to change page
oracle.jbo.server.DBTransactionImpl.createPreparedStatement: JBO-27122: SQL error during statement preparation. Statement: select po_header_id from po_headers_all where po_header_id=1

Please suggest what could have been wrong while developing or deploying the application.
P.S. : The view object (header) shows data successfully when run in the application module. Also, a .db file gets created in the SD card folder. The synchronisation is a success when mSync.exe file is run in the <Oracle_Home>/Mobile/Server/Sdk/bin.

Sorry my content got repeated.
you can go through this thread FOD mobile db sync with base adf server db not working
there is link that you can follow for synchronization (check second last message)

How to debug a Mobile client application

Hi,
How to debug a mobile client application on the laptop, where we dont have any .NET 2003 application installed. (not an MDW)
If we get any error on the application, which could be a UI error on laptop, and if everything is working fine on the MDW, is there any way to debug the application on Mobile client?
Also, please provide me links or tips on how to debug the mobile application, on MDW as well.
Regards,
Praveen.

Hi,
to be able to debug on a local machine you would need at least to install the UI/BOL class files and the project files and make some local settings.
But anyway on all clients there should be the same MSA installation like it is on the MDW so in case of an issue it is normally caused by local (inconsistent) data.
I would suggest to access the laptop IDES database by changing your MDW odbc settings and perform the debug session on the MDW.
Debugging in VB .net is similar to VB6 but you have to notice that changing of the code is NOT possible when being in debug mode.

Wolfhard
