Development of enterprise applications

Hello
What are your advises on using model driven development in developing enterprise applications. LiveCycle Data Services looks very promising, I have found numerous tutorials/videos that shows how fast an application can be build by having methods/functions auto-generated.
What are the best-practices, is it good/bad to use those auto-generated methods, they can really save a lot of time.
All suggestions are welcome, also if you know some existing blog/discussion please let me know.
Thanx

Any generated code is going to follow a specific pattern, and is not a one size fits all solution. Depending on the application, it is important that developers have the ability to customize the generated code to suit their needs. With Data Services, not only can you generate code, you can customize the generated code.
There are a couple of options to customize code:
1. Modify the template: All generated code is backed by a template (we use Freemarker). You can modify the template to fit your application design pattern. The limitation with this approach is that you cannot add/remove templates.
2. Plugin to Modeling plugin: Developers can extend the modeling plugin, and hence the code generation capability. With this approach, developers have full control on what gets generated.
Note: You need to have a good understanding of Fiber core and it's APIs to successful control code generation. These API are in Java and provides you a run-time representation of the data model.
Model driven form follows the same pattern. It is unlikely that you like the generated code as is - I would recommending modifying the template (especially the look and feel) to suit your application design.
However with some application all forms may not have the same consistent look and feel. In such cases, the generated code may be a good starting point, but may require context specific customization.
One of the limitations with LCDS code generation today is that we don't support multiple templates in an application. Developers cannot choose a different template for each entity. We may add this capability in the future. However, if this is really important, you can always extend the plugin to offer this functionality.
Hopefully this provides the information you were looking for.
Thanks,
-Anil

Oracle Solutions for development of enterprise application

Can anyone tell me what my options are in the Oracle world for developing an enterprise application, and what would be needed for deployment?

It appears to me that for a Forms application you HAVE to purchase the Enterprise Edition of the Application server because it is the only edition that has the Forms (and Reports) services, which is needed for a Forms application. This is priced at 30,000 per processor.
Whereas, all you need for a J2EE application is the Java Edition of Oracle's Application Server which is 5,000 per processor.
Is my assessment correct?

Is it legal to use the iPhoto slideshow video inside the third party iPad enterprise application?

Hi,
we are developing one enterprise application specifically for iPad.Kindly advise me is it legal to use the iPhoto slideshow video inside the third party iPad enterprise application (slide show with images)?
Thanks in advance.

Thanks Terence for your reply. I mean for "the iPhoto slideshow video" is : I have collection of my own images , using iPhoto software i created a slideshow based on 'origami' theme and exported as a video file. Can I use that video in my enterprise iPad application?
Thanks.

Problem in building the enterprise application using Ant -Wrkshop

Hi All,
I have developed the enterprise application using workshop and tries to build the application using Ant script and getting the following error.
"An error occurred writing the controls client manifest."

Did you:
a). Ensure you're using the correct version of WLS (it appears to me you're using a standalone WLS)? - correct version is 10.3.3
b). Install the application development runtime 11.1.1.3?
c). Extend the domain with the JRF?

Best development platform for enterprise applications on the Oracle DB

We have been developing enterprise applications for many years based on Oracle technologies, right now we have reached a significant number of systems developed with Oracle Forms 6i and a few ones with Oracle Forms 10g. Although according to Oracle Statement of Direction of March 2012 Oracle remains committed to the support of Oracle Forms and Reports, there won’t be new features added to these products, and we can predict that eventually they are likely to be discontinued. Although we will continue using the Oracle Database, we have started to look for a replacement of our development platform, for the new developments and the migration of our existing Forms applications. Our Oracle database is installed on a Linux server. We are also planning to retain our existing programming staff and most of them have no experience with other tools or languages.
This way, I would like to hear from people who has faced the same problem what development platform (development framework, IDE, programming language, application server) they chose for developing their next generation enterprise applications and what factors they considered in making that decision.
Any suggestions, ideas, recommendations, considerations or advices you can give us would be welcome and really appreciated. Thank you very much for your time and thank you in advance for your answers.

Your question is not an uncommon one. However, my opinion is that which product or technology you use for an application should not be solely based on what is "cool" today. Some of today's most popular product may not be able to do what you need them to do or at least may not allow you to do it easily. You need to use a product and/or technology which falls into this group:
1. Does the product/technology offer the features our application will need?
2. Does the product/technology scale to the level we need? Both in user base and application size?
3. Does the product/technology offer the level of security we need?
4. Does the product/technology fall in line with our development team's skill set?
5. Does the product/technology fall in our budget?
Whether you are speaking of an Oracle product or competitor's product, all have their advantages and disadvantages.
The views expressed in this posting are my own and do not necessarily reflect the views of Oracle.

Regarding Enterprise Application infrastructure development

Hi all,
I am working in a development process of an enterprise application in java. I want help from expertise to develop the infrastructure. I am planning to use STRUTS for the Web Client EJB3 for Application Business Logic in JBOSS AS. In this context i want to know how to send the complex object from the client to the remote EJB server.
thank u

So you are telling if i am having a Entity Bean that also i need to keep in client side to assign value to it,
or i should use a client business bean and send it to Application Server and from there, i should use a
translator for translating from the client business bean to the business entity in the Application server and
send back the client business after reverse translation.that's entirely up to you. there are respected EJB developers who will argue both sides of that debate. i personally prefer not use entities as DTOs because it tends to cause more issues than it solves, but i've written applications both ways.

I have the same problem, when I delete row and after that I use refresh button in internet explorer. What I do is I drag and drop button "removeEntity" and edit it in backing beans adding new bindigs that commit changes and referesh page. Code:
public String commandButton2_action1() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("removeEntity");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
OperationBinding commit1 = bindings.getOperationBinding("Commit");
commit1.execute();
OperationBinding requery = bindings.getOperationBinding("findAllRezerwacja1");
requery.execute();
return null;
In page definition I added "Commit" action and code with methodAction is:
<methodAction id="removeEntity" InstanceName="SessionEJBLocal.dataProvider"
DataControl="SessionEJBLocal" MethodName="removeEntity"
RequiresUpdateModel="true" Action="999">
<NamedData NDName="entity"
NDValue="${bindings.findAllRezerwacja2.currentRow.dataProvider}"
NDType="java.lang.Object"/>
</methodAction>
<action id="Commit" IterBinding="findAllRezerwacja1Iter"
InstanceName="SessionEJBLocal.dataProvider"
DataControl="SessionEJBLocal" RequiresUpdateModel="true"
Action="2"/>
Can sb tell is there is normal that when I delete row in table, and after it I refresh manually by IE page is normal that I get error messages. I this is the same situation using Back in IE. Deleting row that is commited to database works fine, but the problem is with manually refreshing page?
Next question is about using Delete action from node instead of removeEntity, what is the difference? As you can see, I use removeEntitity method. Choosing Delete action instead doesnt works. Why? Rest of the code is the same but instead of dropping method removeEntity I drop Delete action
Sorry for my English, its not my native.
Thank in advance

Hi CV,
Oracle Application Development Framework Mobile (ADF Mobile) browser is a standards-based framework that enables the rapid development of enterprise mobile applications. Oracle Fusion Middleware 11g release 1 of ADF Mobile browser extends Oracle ADF to browsers running on mobile devices. Because ADF Mobile browser is built upon the component model of Java Server Faces (JSF), you can quickly develop applications for mobile browsers. ADF Mobile browser's mobile-specific extensions to JSF enable you to develop mobile applications using the same methodologies for developing JSF applications for the desktop.

Deployment Problems of Enterprise Application in NWDS 7.1

Hello Everyone, 
 
I am having a problem when trying to deploy an application I made to the server. The project consists of two DCs, one which is an Enterprise Application and the other is a Web Module. I have configured the web module to be a dependency of the Enterprise application, so that the .war file generated from the Web Module DC is contained within the .ear file created when the Enterprise Application DC is built. The only dependency that the Web Module DC has is "engine.jee5.facade," which is there by default when it is created. I have not added any code to either DC, because I was just trying to test if I could deploy something to the server before I got into that. When I build the Enterprise Application DC, both DCs build successfully (because of the dependency). When I deploy the Enterprise Application DC, I get an "[ERROR CODE DPL.DC.5089]" error message. When I checked the SDN for what that error code means, I get sent to <a href="http://wiki.sdn.sap.com/wiki/display/JSTSG/(JSTSG)(Deploy)Problems-P58">http://wiki.sdn.sap.com/wiki/display/JSTSG/(JSTSG)(Deploy)Problems-P58</a>, which is pretty vague.
I did try to see if I could deploy the .ear by itself, without the war file within it (by removing the dependency on the Enterprise Application DC) and that seemed to work ok. Its just seems to be when the Web Module is a dependency of the Enterprise Application is when it fails. I have included the error message I get from NWDS below. Thanks in advance for any help you can offer. SUMMARY

Please find my ans to the following points mentioned by you
1) BASIS SWCV must be assigned in the Distribution Model Software Component Version tab of the device.
It is assigned
2) Activate the "DISTRIBUTE_USER_DETAILS" Rule in the admin.
Rule is activated
3) Activate the "DISTRIBUTE_USER_AUTHORIZATIONS" Rule in the admin.
Rule is activated
4) Make sure that you have installed the following components in the following sequence in the PDA
- Creme
- MinDB/DB2e
- PDA_eswt_container
- PDA Runtime.
Client is installed in this sequence only. I referrred to help.sap.com while installing
the application should atleast work in the NWDS PDA simulator. My basic problem is it is not picking up the data. giving the above mentioned error.

Multiple enterprise applications

We are in the process of designing multiple enterprise applications. We want to utilize some of the basic core Java EE patterns i a Websphere environment. My question centers around the architecture of the applications/components and the deployment.
For example, since I have multiple apps, can I deploy multiple web apps (war files) while utilizing an enterprise suite of EJBs to service requests from any/all applications? Let's assume that the web apps are all deployed in the same box (jvm) for now but it may be necessary to deploy them in their own web container (physical server) in the future.
Is this possible and has anyone done this? How should we develop and deploy the war/jar/ear files?
I have done this in the past but with home grown middleware. Thanks.

For example, since I have multiple apps, can I deploy multiple web apps (war files) while utilizing an enterprise suite of EJBs to service requests from any/all applications? Yes. The deployment strategy you're outlining is a good fit for the Remote EJB view. The Remote EJB clients(your web apps) can be packaged within the same .ear as the EJBs themselves, or in separate applications(.wars or .ears) Those separate applications can either be deployed to the same server that hosts the EJBs or to a different tier altogether. Because the Remote EJB view is location transparent, the application behavior will be the same. Of course, performance will differ.

Suitable for big enterprise applications?

Hello,
I am an advocate of Apex in our Oracle Forms shop, but received the following statement: "I am afraid that because of its 2 tier architecture (entire processing is taking place in the DB) it is not suitable for big enterprise applications".
Please help me respond to this.
Not by saying "yes, it is" or "no, it is not, the person is right", but by saying why it is or it is not.
References would be nice too.
Thanks very much, in advance,

As the Director of IT for my company, here's why we use APEX as our main data entry/reporting solution:
1) Centralized data. All the data resides in a single place. No duplication and no wondering "Is this everything?"
2) Anywhere access. Because it is web/browser based, your users can gain access to the system whether at work or on the road. My company operates in the transportation industry across more than 8 states and we support many traveling managers. Web-based access and wireless connectivity enable them to be anywhere and get access to real-time data.
3) Instant deployment and updates. With APEX, content and new functionality can be instantly deployed across an entire organization without the need for expensive software management agents. It also eliminates versioning problems because it ensures everyone is using the same version. You can't do it that simply with a normal enterprise application.
4) Cross-platform Compatability. Again, because everything is browser-/standards-based, users can use Apple, Windows, Linux, smartphones, etc. Most standard applications have to have specific components written to interact with each type of device or operating system. With web applications, you can develop once and deliver everywhere.
5) Rapid development. I can have a basic application developed including table definitions, etc. in a matter of days BY MYSELF.
About the comment, I'd like to know what types of enterprise applications AREN'T 2-tiered or even 3-tiered applications? You have a presentation layer and a data layer in all applications; the application doesn't house the data itself. The main difference between APEX and many other applications is the delivery method: instead of a proprietary/internal transfer of data between the data layer and the presentation layer, it's being run out over the Internet. Frankly, the concern isn't about the tiers, it's about something else and the objector doesn't want to tell you the real reason.

How to deploy enterprise application OTA?

Hello, I am Sungwoo Bae.
I am slightly new to enterprise program, Because I was mainly developing apps for appstore.
Before iOS4 is released, I deployed simple in-house application and certifacate using iTunes.
But our client feel uncomfortable about deployment way which require to use their PC and iTunes.
With relese of iOS4, I heard there is new way to deploy application OTA from my colleague.
I was searching web to find that way, but I can't find.
It is true that there is new way to deploy device configuration, but I cannot find about in-house application anywhere.
I also tried to get apple's support, but I couldn't get the desired answer.
Is there something I missed?
Please let me know if there is any way of deploying enterprise application OTA.
Thanks.
Sungwoo Bae.

For that feature, you need to setup MDM (Mobile Device Management), and some of Apple Engineers told me that MDM infos are only available for Enterprise Program subscriber....Apparently, it does not.....
Any info about MDM is really welcomed from Apple that sold this feature as a major new feature for iOS 4.
