Database Lite and JDeveloper / ADF

Hello,
I'm planning to create a small application which will run on mobile PC in an off-line mode, having synchronization with master DB once connected to the proper network.
The main architecture on the target PC may be :
- Oracle Lite
- GlassFish
- ADF application
I downloaded JDeveloper 11.1.1.3.0 and the latest version of Oracle Lite (10.3.0.3).
I'm looking the tutorials but none of them are talking about the JDeveloper 11g version, they all speak about BC4J/OC4J. Since I'm new to Oracle's product I don't know these "products" (framework ?) and in the 11g version this seems to have disappeared.
Are those versions compatible with each other ?
Will the tutorial work ?
Regards
PS: the same thread is present on the JDeveloper forum

The main thread will be the one on JDeveloper section :)

Connect between database oracle and jdeveloper

i want a simple example to connct database oracle and jdeveloper
to insert record or update or delete or query

The easy way: http://www.oracle.com/technology/obe/obe1013jdev/10131/masterdetail_adf_bc/master-detail_pagewith_adf_bc.htm

Bc4j.xcfg, database connections and deploying ADF apps to oc4j

I'm trying to understand how to enable custom database connections on a JDeveloper ADF application deployed to a stand-alone instance of OC4J.
All entity objects were created as ADF Business Components.
I looks like the db connection information used by the application is stored in a file named "bc4j.xcfg".
How would I change the database connection information between different environments, changing the server, port and password information from an OC4J instance?
I'd like to use an OC4J defined data-sources.xml file, but am looking for the simplest approach for now.

Tomato tomaato, call it what you will, we now have to spend time (money) figuring out how to change from using the recommended use of a "connection" from Oracle tutorials and in Oracle Press books.
Plus, neither I nor our client can get JDeveloper ADF 10.1.3 to work on OAS 10.1.2.
Oracle has been of little help, other than stating to follow documentation. We followed the documentation at least a dozen times and on three different install of OAS 10.1.2.
Why doesn't JDeveloper have a check-box or button that reconfigures the application to run on 10.1.2 (J2EE 1.3), there is a check-box to change JDK versions (1.4)? This is suspect to me.
We are going to be speaking with the client this week, and have to state the ADF application works, but NOT on OAS 10.1.2.
Does ADF work on OAS 10.1.3, absolutely, but the client is in 10.1.2 and can not upgrade at this time.
I've read in blogs where lots of developers have the same issues without resolution and Oracle should just come out and state that 10.1.3 does not work on 10.1.2.
So my experience has been a mixed bag with ADF, both in terms of the software and customer support from Oracle.

Database constraints and Struts ADF

I have a struts ADF project and wish to pick up unique constraint violations from the database(only the database)
How and where to i trap these violations

The toy store demo has two java classes called
toystoreDBtransactionfactory & toystoreDBtransactionimpl.
These are used to overide the default functionality of
DBtransaction and DBtransactionimpl. The configuration
manager (right click your bc4j application module) allows you to set the database transactionfactory class to the overriden classes. The toystore routines basically capture the databse constraints and reformat the messag einto something more meaningful.
When i run the bc4j tester the changed routines function correctly for example when doing an insert.
With a struts jsp program a similar insert doesn't trigger the changed routines so i just get the database error comiing back to the screen.

JDeveloper, ADF, lack of support and bleak future

Hi,
I'm a seasoned Java and .NET developer, used to many environments and frameworks. A happy user of Oracle databases.
For a very Oracle oriented client I started with a team of developer a project using JDeveloper (no choice). After 4 months of using JDeveloper, ADF to build web sites, here are some thoughts I would like to share. This remarks only focus on that products, because I have a lot of respect for the Oracle databases and had a lot of success with them.
I am starting to get depressed about the very few blogs (most from Oracle) talking about JDeveloper and ADF, the lack of books, and the Oracle forums.
Moreover, most of the time you never get an answer to your problems, sometimes untested not working 'solutions', and a very very few times a working solution. Help is sparse, the community is missing.
If Oracle wants to promote its framework, it has to boost the number of tutorials, examples and support.
Googling about ADF is most of the time a non sense since you always land on the same 3 blogs and the Oracle forums.
Proof of non use by the community ?
If you try on www.indeed.com to find statistics about JDeveloper or ADF jobs you get another frightening proof.
Sometimes you find a piece of code or a tutorial that may help, but you realize it works only on some specific release of JDeveloper.
What makes me angry is when you ask why your code works on the x.x.x.x version but not the newest version, and the only answer you get is stay with x.x.x.x version (I won't bother to fix your 10 lines or code or even give you a direction to do it (maybe coz I don't understand myself were the breaking changes are)).
JDeveloper is damn too slow ? You should have a dual-core and at least 2 Go of memory, you poor thing ! Is Java for rich people ?
Debuging is a nightmare. Compared to Eclipse or others it is not practical at all.
I'm happy when I can create a few pages drag and dropping controls. Business components are also a good thing. It speeds up my development. But since development is not just UI and generating business components, I lose a lot of time every time I want to write code, every time I do something "exotic" it becomes a pain in the ass.
My problem here is that the architecture and JDeveloper constraint the developer a lot. I don't even talk about the fact that everything is only Oracle database oriented (openess ?). Even changing your page layout is a pain. Positioning controls is non trivial. As a whole, I would say that this whole thing imposes you to adapt to it, it doesn't adapt to you and your way of working.
Most results I saw look like the Oracle websites.
I could go on about the various bugs and problems that plague JDeveloper. Like the refactoring (when usable) that leave old and annoying stuff in your model XML, like the bugs in the diagrams, like problems related to auto-binding on the page and manually changing controls ID, various synchronization problems between pages and backing beans, adding upload is a mess, OrdDomain types are buggy, regions doesn't work well in the designer, and so on...
My point is that I feel the whole thing is not mature. And Oracle seems to fix some issues with the release of JHeadStart. Sometimes you fix things by integrating JHeadStart stuff. JHeadStart is probably a great thing and a time saver if you don't do too much "exotic" screens and code, but does it means that JDeveloper+ADF and classic development becomes a second class citizen ?
This is sad, since the ADF framework and JDeveloper look good and are worth of a more widespread usage. But marketing and support are way way far behind other commercial and open-source solutions. When I see what is planned for JDeveloper 11 and I compare it to others (Java or not). When I look at the developers needs and expectations, I feel we are losing the race.
Maybe Oracle would like to hand over some of the framework to the community, but my feeling is that the community is already commited on other exciting and less constraining frameworks and tool, and this community may well work in a way that doesn't fit Oracle vision. Future will tell.
Cheers.

Hi,
thanks for the detailed comment. I appreciate the time you spent writing this up as this helps to improve the product. Below is a first - quick and brief response to some of your statements.
... for documentation and tutorials
http://www.oracle.com/technology/products/adf/learnadf.html
Especially the ADF Developer Guide for 4 GL developers earns a lot of praise among J2EE developers.
http://download.oracle.com/docs/html/B25947_01/toc.htm
... for books
http://www.oracle.com/technology/tech/java/jsf.html
Sometimes you find a piece of code or a tutorial that may help, but you realize it works only on some specific release of JDeveloper. What makes me angry is when you ask why your code works on the x.x.x.x version but not the newest version, and the only answer you get is stay with x.x.x.x version
Of course samples need to be created to some point in time with a specific version. We have SRDemo as our main - maintained - reference demo I suggest you download this sample from OTN using help--> check for updates. Note that SRDemo contains code solutions for most developer cases and also is available in 10.1.3.1
I'm happy when I can create a few pages drag and dropping controls. Business components are also a good thing. It speeds up my development. But since development is not just UI and generating business components, I lose a lot of time every time I want to write code, every time I do something "exotic" it becomes a pain in the ***.
What is exotic, and what are the questions you didn't get an answer for ? I see that this is your first posting on OTN, so I am wondering under which account you posted the other questions that did not get an answer.
Googling about ADF is most of the time a non sense since you always land on the same 3 blogs and the Oracle forums. Proof of non use by the community ?
Isn't OTN a community ? I don't think that we need another discussion forum and looking at OTN it appears very active.
I don't even talk about the fact that everything is only Oracle database oriented (openess ?).
Not true. Please prove your claim.
Even changing your page layout is a pain. Positioning controls is non trivial. As a whole, I would say that this whole thing imposes you to adapt to it, it doesn't adapt to you and your way of working. Most results I saw look like the Oracle websites.
Now you are barking up the wrong tree, blaming ADF for what is JavaServer Faces layouting. You don't have to use JSF but can go for JSP /Struts and/or Swing development. What is the view layer technology of your choice that allows you to do better layouting ?
I could go on about the various bugs and problems that plague JDeveloper
Yes, please post them all
... regions doesn't work well in the designer, and so on...
Of course, because regions are not officially supported. JDeveloper 11 - I know you don't want to hear future - will have full templating (going far beyound of what facelets do) and region support
My point is that I feel the whole thing is not mature. And Oracle seems to fix some issues with the release of JHeadStart.
JHeadstart is a consulting offering and not meant to fix the product.
... but does it means that JDeveloper+ADF and classic development becomes a second class citizen ?
No comment for this statement as it is based on a wrong observation
This is sad, since the ADF framework and JDeveloper look good and are worth of a more widespread usage. But marketing and support are way way far behind other commercial and open-source solutions. When I see what is planned for JDeveloper 11 and I compare it to others (Java or not).
Note that only a fraction of new features in JDeveloper 11 leaked out so far or have been mentioned in the recent statement of direction. JDeveloper has many more features that we don't yet promote because the software isn't available.
Please note that we give ADF to the community. Its just we are not giving it to the open soutce community but the J2EE community (JSR-227)

10g database, cluster on aix and jdeveloper

Are there some known incompatibilities between oracle 10g database with cluster on aix and jdeveloper application (jdev 10g) using dynamic jdbc credentials (jsp, bc4j, adf)?

My application vendor advises me that my patch level on AIX should be equivalent to that of the following windows patch level.It may not be available becuase most of them are OS specific..If there is patch for Windows behaviour how are you expecting a patch for an Unix version
Explain your vendor about this buton the other hand if it is a generic issue then you should look for AIX patch

Database Lite License and App Tutorial

Hello,
I'm looking for information regarding oracle database lite licensing and if any one could provide me with demo/tutorial on an application built using oracle jdev with ADF for mobile that uses oracle lite.
Currently I have developed a demo mobile browser application (using oracle ADF) that does not use oracle lite and works only in connected mode. Any documentation on how to go about with oracle lite and work on offline mode/ synchronization would help me.
I have a fair idea on licenses, Please correct me if I'm wrong or require any other,
Oracle Database Enterprise or Standard Edition,
Oracle Mobile Server,
Oracle Weblogic Server,
ADF Runtime licenses
Greatly appreciate your input.
Thanks and Regards

Hi,
Related to Oracle Lite you need to license:
- the Oracle Lite Mobile Server
- the Oracle Lite client (for each device)
If you want to have an aproach check any online store of Oracle, but anyway you will have to contact an Oracle Partner for licensing, discounts, etc... if your partner know about mobile ;-)

How to implement hierarchical structure of managers and reportees using jdeveloper adf

I want to display hierarchical structure(which can be expanded and compressed) with 3 columns(Employeeid, fist Name,lastname) of managers and his reportees on selecting a top level manager.
In this i'm going to use programmatic view objects.
I have employees table.
Here is my detailed requirement:
On selecting a user from drop down list, i want to display the list of users reporting to him.
From the displayed list on selecting a manager, list of users reporting to him has to be displayed in a tree format with the correspoding just being listed below the current selected manager
Example :
Top Manger has been selected from dropdown and clicked submit.
Output(a table as mentioned below):
Manager1
Manager2
NonManager1
Manger 3
On clicking manager1,
output:
Manger 1
Manger11
Manasger12
Nonmanager11
Manger 2
NonManger1
Manger3
on clicking manager1 again, tree has to be compressed and the output has to be just the same as first output.
Please help me on this by sharing information or any references on how can i achieve this implementation using Jdeveloper adf concepts.
Will be waiting for the inputs.
Thank You,
Dev

Obviously, you can only display one picture. So then the question becomes which picture to show. Therefore, you will have to create some sort of preference of one pattern over another.
I would use a FOR loop so that you can loop through your available patters and their possible results. Use the Conditional Terminal on the FOR loop so that you can stop the loop on the first match. Then you just wire up the selected value for the ring outside of the loop.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

REM Create object ORDER_ITEMS_REC

and the error message I got was
------------------------------------------------start
Error report:

------------------------------------------------end
I was wandering whether the error of FOD installation could cause the error of the tutorial?
Any response will be appreciated.

1. you dont have to insall Oracle database at the BO machine side, you just need any database to hold the BO repository.
2. you cant connect directly using BO, only Crystal reports can connect directly to R3 database, you need to have a BW in between.
extract your data into the BW, and let BO connect to BW using the BO integration kit for SAP solutions.
3. no you dont have to have 3 different machines, using one BO machine you connect to them all, but you may need build a BO environment, (Development, Production servers)
good luck

Synchronization of database schema and EJB3 / JPA objects

Hi,
I am evaluating JDeveloper 11g. My goal is to create applications using JPA / EJB3 , ADF in rapid manner. I am stuck on really simple thing. I created my first web application (address book) where User has only 2 fields First and Last names. Now I would like to add an address field in to database (offline and online) and also to my EJB3 bean User. I can only do it manually by doing the same action on the database and ORM level. I consider it pretty serious hurtle for medium+ site projects.
So my question is if there is any way to automate the process of modifying database structure or EJB3 beans to make both in sync (database and beans).
If there is no such function I suggest that it makes sense to implement it.
-- Sergei Rogovskiy

Sergei,
I filed an enhancement request for this, not knowing how difficult this will be to implement
Note that JDeveloper 11 has its own forum: JDeveloper and OC4J 11g Technology Preview

Database Lite with Apex

Hi,
I am looking at developing an integrated system for a client who requires that their off site tablet pc’s are able to synchronize with their central 10g database.
Database Lite looks ideal for this I am just looking for answers on a couple of points.
1. Does Database light allow for the installation of Application Express on the client system? This is our preferred development environment.
2. Can it be installed on Windows XP Professional Tablet PC Edition?
Cheers

If you want a HTML/Web app, you could either go with .Net or Java. You could build a PHP app I suppose as well. Most common use of web technology with Oracle Lite is Java/JSP J2EE (Oracle's ADF). The benefit of going with a Webtogo-OC4J application is that it is the easiest to deploy and maintain from a user deployment perspective. Java and J2EE, though are probably the most difficult in finding resources to build the application though. So there are pros and cons. It really revolves around the skill set of the organization. Frameworks in Java have made development smother than they were in the past and if you have the skills between J2EE and .Net, I would recommend J2EE for Oracle Lite.

OBIEE 11.1.1.7 and JDeveloper integration

Hi all,
I am integrating OBIEE 11.1.1.7 with J Developer. I have installed OBIEE 11.1.1.7 and JDeveloper 11.1.2.3.0 on my machine. Can anyone tell me the further steps to move on.
As per my research, I have to download an extension called Web Center portal in JDeveloper. But it is not getting displayed in the extension list. Is it compatible with this version ? If not, then which versions is it compatible with.
Apart from this I also came across the extensions called BI ADF task extension Bundle, BI ADF Bundle. Can anyone provide me appropriate links that demonstrate use of these extensions (Any tutorials or so).
I am just trying to explore the possibilities of OBIEE with J Developer.

How to connect to 8i Lite from Jdeveloper ?

Hi,
is it possible to use 8i Lite as Database Server within Jdeveloper environment ?
We plan to use a three tier architecture with:
Client : thin client
Middle tier : JSP+BC4J
Database Server : Oracle 8i ( for the central environment ) and 8i Lite for satellite systems (about 100).
The Central system use Oracle Replication technology to refresh data on Satellite environemnt.
Does it make sense to use 8i Lite ?
thank you for your suggestions.
You can also mail to [email protected]
Jean B. Mvuyekure

You can uses the latest version of the 8i Lite driver to connect from within JDev, but only using straight JDBC. None of the wizards nor the BC4J will yet work with anything other than a real Oracle RDBMS.
