JDeveloper ADF Plugin

Hi,
I'd like to realize a JDeveloper plugin which can handle ADF components such as Entity and View Objects.
In the Navigator view, Entity and View Objects are instances of the class:
oracle.jbo.dt.jdevx.ui.JdxNode
and I'd like to handle these objects using this class.
Is it an open-source class?
In which library can I found it?
Thank you in advance,
Daniele

It is not available in JDeveloper PS3/11.1.1.4. We have to wait for longer.
Please have a look into this forum thread for more details - where Oracle guys has given their inputs regarding it

Thanks,

Eclipse ADF plugin

I'm under a big pressure in ordrer to adopt Eclipse.
I like very much ADF and I don't like to loose theese functionalities.
Is there any ADF plugin for Eclipse (I mean something like JDev wizards) in order to manage them ?
Is there any way to use ADF client in that environment ?

Ha ha "lack of speed".
Wasn't there a comparison of speed of IDEs some months ago, where the Eclipse-based IBM IDE pretty much came in last? Or did I imagine that?
Maybe it would have been wiser to wait for the finished product, instead of comparing Eclipse with an EA version!?
I remember a comment that Brian Duff posted in one of his blog entries more than a year ago (and I actually looked it up again so that I can quote it here):
Java is all about choice. That's what distinguishes it from .NET. As a Java developer, you can choose which Java IDE is best suited to your needs.
A lot of people like Eclipse, but there are a substantial number of people who use something else. That's good and healthy: the competition gives rise to innovation. Just look at how features like refactoring have been at the core of many Java IDEs for years, and how Microsoft is only now catching up with these innovations in Whidbey (VS.NET)
I couldn't agree more. In other threads I read some comments that Oracle should give up JDeveloper and "jump on the Eclipse band wagon".
No, they shouldn't! It's good to have a choice, and the current trend of giving up IDEs and shifting everything into the Eclipse direction is plain stupid. Do we really need another monopoly?! Competition is good.
And this SWT thing ... don't get me started.
So instead of criticising Oracle for holding on to JDeveloper, people should be thankful instead. Should Oracle give up one of the key advantages of JDeveloper (the ADF integration)? Now, that would be stupid. Did the Eclipse people program code refactoring extensions for JDeveloper when they were needed? No!? Hmmm ... I wonder why.
Why would we want to switch to Eclipse? Just because Eclipse has some "coder goodies" that JDeveloper hasn't? We started with JDeveloper 9.0.2 and I can tell you, this IDE was pretty basic in the "coder goodies" department. We chose JDeveloper anyway, and we didn't regret this step --- not for one minute. Because JDeveloper isn't just about raw Java coding. JDeveloper truly is the Swiss-Army-knife of IDEs.
Of couse, if you do a lot of screwdriving, a Swiss-Army-knife is probably not the best choice. You choose a real screwdriver instead for that task (that would be Eclipse, a golden screwdriver!).
But if you do a lot of different things, and you need a set of tools integrated and working well together, well then it's the Swiss-Army-knife for you.
(Damn, did I just come up with this brilliant allegory, or did I read it somewhere?)
"I think it is a pitty that when you want to chose a specific framework, you're locked in to a specific IDE."
Well, that's what JSR198 would be good for, isn't it. Oh wait, I believe the Eclipse guys are not participating there and will keep their own plugin model. Or am I wrong?

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

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

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)

'WHEN-NEW-FORM-INSTANCE-trigger' in JDeveloper/ADF/JHeadstart

Hello,
I'm new to JDeveloper/ADF with JHeadstart.
I want to execute a PL/SQL-procedure when the application starts. I've added the method to execute the PL/SQL-procedure to the Application module class.
How can we execute this method?
Thanks in advance.
Richard Teunissen

Richard,
When using security, it is easier to add a servlet filter to your application that only calls the PL/SQL procedure when user just logged in , which is start of new session.
Without security, it is easier to do it each time you enter a new page.
You can drag and drop the app module method on your page, then create an invokeAction in the executables section of your page definition that executes the method binding, and set the refreshCondition of the invokeAction to #{!adfFacesContext.postback}.
See ADF Developers guide, sections 8.4, 17.3 and 10.5.5 for more info:
http://download-west.oracle.com/docs/html/B25947_01/toc.htm
Now, if you are new to ADF this might sounds a bit cryptic, I strongly recommend you take some class on ADF, for example the ADF/JHeadstart workshop:
http://blogs.oracle.com/jheadstart/workshop
JHeadstart is a great help when moving from Forms to ADF, but you still need to learn how ADF works, to be able to fully leverage the power of JHeadstart. It is like generating Forms using Designer, thevbetter you know Forms, the more advanced functionality you can generate using Designer. The JHeadstart generator is very flexbile, using custom templates you can generate almost anything you want, but it requires knowledge of ADF Faces, JSF, ADF bindings and ADF Business Components to create those templates.

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.

Oracle JDeveloper ADF Problem

hi to all,
I encountered a problem while designing a web page using JDeveloper (ADF)...
Firstly i would follow these steps
1. Create DB Connection
2. Create entity tables
3. Create view objects
4. Create face-config.xml
5. Create relevant JSPX pages using ADF core drag and drop function from DataControlPalette
All the steps work out just fine... However, if i try to repeat steps 2, 3, 5 again to add new functions, the JSPX pages created will not display a inputtext box field when being rendered on Internet Explorer (JSPX pages are created using ADF drag and drop function from DataControlPalette)
Its seems that if i take away the bindings from the inputtext box, the inputtext box would be displayed, however it would not pass the values to next page nor add values into DB...
Is there anyway i can keep the bindings approach and remove the error in inputtext??

Hi Frank,
I followed the same steps as in the tutorial of SRDemo to develop the application
It always works on the first use case of the application. However, only if i try to add another new use case(entities, view object and jspx pages) will the inputtext not be rendered on IE...
It seems that if i use a view object created through their sql (Select from DB...), i can obtain information and display it in a adf form where the inputtext box is displayed... However using the view object created programically, the inputtext box does not come out in adf form...

XML validator in Jdeveloper/ADF

Hi,
I have xml in String variable and want to validate again xsd. Any input on how we can do this in Jdeveloper/ADF
Thanks in advance.

This bug has been fixed for the Production Release. There is no manual fix I can give you for the Preview Release. When you say this is a compile-time error, do you mean that this is preventing you from compiling your project in some way? The error should just appear in the editor when you have the Ant buildfile open, and you should be able to safely ignore it.

JDeveloper ADF on other webserver

Hello,
In terms of Technical setup, I have the following questions
Can JDeveloper + ADF work on other webserver than Weblogic? If yes, which?
What does ADF add to JDeveloper?

For ADF Essentials you use the same JDeveloper version.
Note that if you'll search on the Web and this forum you'll also find people who managed to run ADF on Tomcat, and parts of ADF on JBoss and other servers.
So the list that Timo provided is the "official" supported and tested servers.

Configure JDeveloper ADF Project based on user properties

I have my own project code tree and would like to create a JDeveloper Project based on that. Is there a way to instruct JDeveloper to read the source file locations from a properties file.
For example, look into \trunk\jsp_src for all the jsf files ; look into \trunk\config\webWEB-INF for config files like faces-config.xml ...etc.
Thanks
Ramesh

Hi Shay,
I know we can do it this way.
What I would like to find out is if there is a way to tell JDeveloper to read all the configuration information from a user-defined properties file.
That way I can use my code tree checked out into any directory structure from source controls like CVS or Subversion as the code-base for my JDeveloper ADF project.
Thanks
Ramesh

Please, does JDeveloper ADF justify the investment?

Hi everyone, a license for IAS or 100U$ for runtime, seems too much, for a small business (less than 20 clients)
Does JDeveloper ADFjustify the investment or is almost the same, than using Jdeveloper without ADF, which are the real advantages.
Thank you in Advance :)

Hi!!
Im a new JDeveloper - ADF user!
Im using JSF for a short time, but i tried many, many implementations, and i have to say that ADF is the best choice i found, if we mix it with Jdev it gets much more powerfull!
About you question, i wonder if you can use it with tomcat. I know the power of OAS, but in your case, few number of clients, couldnt you use tomcat instead of OAS? JSF generates JSP in the background, doesnt it?
Please forgive me if im saying something stupid!
Best Regards!!!

Are there Any Charting solutions that works with JDeveloper/ADF?

Are there any Charting solutions ( e.g. barchart, piecharts, etc) that works with JDeveloper / ADF ?

This question came up here once before. I think the conclusion is: No, not with vanilla ADF. However, if you're interested, the thread did mention some other library you might want to try.
Good luck,
Brian

JDeveloper & Eclipse Plugins

Hello,
I thought Oracle wrote the specification regarding plugins? If that is true, will Eclipse follow these same guidelines and thus a plugin will be able to work in either JDev or Eclipse? There are so many more Eclipse plugin available it seems much more logical to pick Eclipse over JDev.

The reason Eclipse has so many extensions is because
it is missing so much functionality that is built-in
in JDeveloper.Wow, what an argument Shay..., I'm guessing that is why Collaxa (or should I say Oracle BPEL) made their plug-ins in Eclipse and not JDeveloper.
In my opinion Oracle should drop JDeveloper and start working on opening up their frameworks, like ADF, by building plug-ins like Collaxa did. Focus on what you do best, that being database and application server. I really believe ADF is a great framework, but think you would have a difficult time "selling" it to a prospect who isn't already using some or all of Oracle's stack.
Also have a look at: http://theserverside.com/news/thread.tss?thread_id=27543

Deploying a jdeveloper adf application to a desktop

I need to create an interface to an oracle database system that I set up, and I need to do it posthaste. I got drawn into the offerings of jdeveloper by all the promotion and videos and tutorials that are available on the web page. It does indeed seem like a rapid way to create an interface. I originally liked the idea of creating an adf fusion webapplication, but I couldn't figure out how to get my sample application to run on Tomcat.
So now, I'm interested in developing an interface that can be run on a desktop, in the meantime until I have more time to work on a web interface. My question is does a desktop application need an application server as well if it's using adf? In other words, I'd like to create an application in jdeveloper that I can deploy as a simple executable jar file and send to a user for them to use on their desktop, is this possible? Is web logic required to run on that other users desktop?
I've tried doing this using a "Java Desktop Application (adf)" which creates two projects one for the model and one for the view controller. I created a simple prototype form that connects to my database and everything looks great when I hit the green play button. However when I try and deploy it as an executable jar with the entry point being the one and only form I can't run it. A jar file is created and it says its an executable jar file but when I double click it, the OS simply beeps (I'm using Windows XP).
Thanks.

You should be able to execute the application packaged on the jar file as is. I haven't developed myself anything like it, but as long as your necessary ADF libraries are accessible you shouldn't have any problems running it.

You won't be able to run the jar file that way - unless you package a manifest file with it and set its Main-Class attribute to point to your class containing the main() method. Try instead executing java -jar yourJarFile.jar from the command line.
