DBA learning jdeveloper

I am "self learning" jdeveloper, I have installed the 10g from OTN (dl yesterday) and of course find it a massive ugly beast.
Need a acronym dictionary <G>.
Question, I have looked at all the samples on OTN and ran many of them, but none of them show me what I want.
What I want, to me seems like it should be really freaking simple.
I want a log in page that asks for a user/pass and trys to login to a coded DB.
Then, when successful, a simple page opens that allows users to page up/down a predefined query pumping data into a layout, a dream addition would be search feature.
Nothing Fancy, this can be done in Delphi in about 1 minute, maybe less if your not on the phone at the same time.
Can somebody point me in the right direction please?
Samples I can't find or something like that.

Jeremy,
It is hard to create samples that will fit exactly to what each developer is looking for.
That said here are a couple of things to get you started -
For a simple login procedure check the Reviewer Guide for the simple Struts application -
http://otn.oracle.com/products/jdev/collateral/papers/10g/reviewer/reviewerguide.html
If you want to have a set of predefined queries that people can use the easiest thing would probably be to create an application based on ADF Business Components and with a UIX interface.
One nice thing about Business Components is that you can create view objects that are based on straight SQL (they are refered to as expert mode).
Simply create the views that you want and a default table UIX interface for them.
Again the reviewer guide has a section about building a basic Business Components based application with UIX interface.
For more on the expert mode view objects check out the online help in JDeveloper for:
"Specifying a Custom Query for a View Object Definition "

How necessary is for an ORACLE developer to learn JDeveloper

As you know, the business and programming community has
adopted Java in an unprecedented manner.
Java will be the lifeblood in the infrastructure of many
future (enterprise level) applications and future platforms.
So, I believe it is vital to understand Java!
To develop an enterprise level application without Java,
would be a difficult propositio to sell!
Ofcourse, significant technical expertise in
Designer and Developer, PL/SQL, etc
will continue to be valued for many years to come.
But this is just my personal opinion.

Catch 22: Learning JDeveloper without a db (tutorial requires connection)

I'm trying to build a database model, to use with XE, to create a web-based application with Apex.
I'm on a Mac. I do not have a windows partition so I cannot run XE. I've ordered a windows based laptop but won't have it for several weeks.
Since I don't have a database on my computer to connect to, I cannot use SQL*Developer.
So, someone suggested I use JDeveloper, to create my tables and database model - on my mac. Fine. After several days, I figured out how to get it running, and I'm trying to go thru the Tutorials.
Particularly, the one titled: Database Development with JDeveloper seemed appropriate.
However, the tutorial requires that I've installed the Oracle Fusion schema, FOD Fusion Order Demo Schema. And, of course, the FOD schema requires - you guessed it - access to an Oracle database!!!
Is there a tutorial around for learning JDeveloper that does NOT required being connected to a database????
Thank you
Marion

Hi,
1 way would be to use a placeholder data control. You can create a placeholder data control, with the same structure of your original table, feed in the data, and use it temporarily. However, this has certain limitation (not many data types, manual data entry etc).

I apologize for the delay in responding.
Please check out the DB documentation library for part B19306-01 at URL: http://www.oracle.com/technology/documentation/database10gR2.html. Click on the "View Library" and it should take you to the "Getting Started" tab where you will find documentations on how to get started and further useful information. Hope this helps.

Having problem in learning JDeveloper base on the tutorial

Hi,
I would say I'm new to J2EE and JDeveloper is the first IDE tool that I'm intend to use. I like the tutorial (http://www.oracle.com/technology/obe/obe11jdev/11/ejb/ejb.html) very much as it is easy to understand. I follow the tutorial steps by steps(Note: I create my own schema and tables instead of installing the schema as in the tutorial) and I found that my JDeveloper interfaces are different with the sample in the tutorial. The version that I downloaded is exacly JDeveloper 11g (Preview 2). Is the version different?
When I trying to run HRFacadeClient I encounter errors.
I wish that I can attach document as I have done screenshot of the interfaces. Pls advise how should I further explain my problem? I really need help in order for me to conitnue my learning.
Wen Xi

Hi,
First, really thanks, now I can follow the tutorial with the exact sample interface.
Before I paste my error, first I wish to say that instead of using thr HR Schema that as stated in the tutortial, I use my own schema (wenxi) with two new tables, there are Employee & Department.
After that I just follow the tutorial steps by steps, I have no problem in compiling the classes. I encounter problem when run the HRFacadeClient. Below is my error message. For tracing, I did try to
comment out the for loop corresponding to the queryEmployeeFindAll() method, FAILED. After that I tried to comment out the for loop corresponding to the hRFacade.queryEmployeesFindByName() method and so on. But all FAILED. Below is the message that display after I have commented out hRFacade.queryEmployeesFindByName() & queryEmployeeFindAll() methods.

Fusion Order Demo zip file which works with JDeveloper 11.1.1.3.0

Hi,
Please can anyone tell me where to find the Fusion Order Demo zip file that will work with JDeveloper 11.1.1.3.0 (latest version 13/5/10).
I have downloade OracleXE 10g for Windows on my laptop and now want to create the Fusion Schemas (Tables/Schemas/Procedures etc) for the Demos.
I have downloaded FOD_11.zip, FusionOrderDemo_R1.zip and tryed the instructiion for running Fusion Order Demo here http://www.oracle.com/technology/documentation/jdev.html but each time I get the error
"oracle.javacache_11.1.1 not found"
How can I fix this?
I want to learn Jdeveloper works and use it for Logical and Physical Schema mapping....
Thanks
BP

Hey John,
Thanks for the quick reply, and yes sir, I did follow those instructions.
Let me describe what all I have done so far, maybe someone can figure out where I need to fix anything:
I installed JDeveloper version 11.1.1.3.0, which came with its own WebLogic server, on my windows xp professional OS on my laptop.
I then downloaded the zip file, FusionOrderDemo_R1PS2.zip.
I encountered a problem while unzipping the file, where it was asking me some password for a few files, but Lynn from Oracle helped me figure that out....i had to use 7-zip utility to uninstall....windows default built-in unzip utility does not work.
After unzipping all files, I followed the instructions given on http://www.oracle.com/technetwork/developer-tools/jdev/index-095536.html to import, build and run the application....
And now when it runs....it just open my browser window (IE 7), and shows a "loading..." image in the center of the page....nothing happens after that.
Any idea what might be missing?
a few major errors I see in the wls log window of jdeveloper are:
1) <DCBindingContainer><reportException> [3952] oracle.jbo.JboException: JBO-29000: Unexpected exception caught: java.sql.SQLDataException, msg=ORA-01882: timezone region not found
2) <DCBindingContainer><reportException> [3958] oracle.jbo.JboException: JBO-29000: Unexpected exception caught: java.lang.NullPointerException, msg=null
3) <UIXInclude><tearDownVisitingContext> Tear down of include component context failed due to an unhandled exception.java.util.NoSuchElementException
Please help!

How To: Use ADF Form in "Insert" Mode in jDeveloper 12c

Hi all,
I'm in the process of learning jDeveloper and after going through the basics, a task that I'm trying to accomplish is to have a ADF Form load in "Insert" mode rather than the default "Update" behavior. After significant searches, the closest that I could come to was Create-adf-input-form post. But since that tutorial is based on the 11g version, I'm struggling to find an equivalent of that in 12c.
Can anyone point me in the right directly and help me in determining how I would achieve the same in 12c?
Thanks,
Nisar

Nisar,
If you want the newRow to be readily available when the page loads, you call vo.createRow() in a AM method and expose that method as a client interface. Call this method on the page load.
The below links might help to call method on page load:
Johny's Tips: ADF: How to execute the ViewObject with a ViewCriteria on the PageLoad in ADF Web Application
https://blogs.oracle.com/aramamoo/entry/an_epic_question_how_to
This link helps to know how to create VO row programatically.
http://www.awasthiashish.com/2012/12/insert-new-row-in-adf-viewobject.html
Let us know if you face any issue while implementing.
Cheers

JDeveloper Tutorials

Hi Folks
I installed jdev9033 and started working on it using the tutorials (JDeveloper User Guide Part No A97276-01). To create a user interface, the tutorial on page 3-14 says to right-click on newly created projects node and choose 'New'. In the New Gallery, select Objects in the category pane and Frame in item pane. I don't see any 'Objects' category nor 'Frame' item. I tried to use help menu but landed at the same instructions. Can anybody let me know how I should go about creating a UI with JDeveloper? Can you suggest any other online resources to learn JDeveloper?
Thank you

Here is how I do it.
1. Create a new workspace with an empty project. (right click on the workspace node in the navigator to get this done).
2. Right click on the new empty project and choose New...
3. Expend the client-tier node in the new gallery and choose the Swing/AWT
4. Choose frame on the right side.
Shay,
Oracle.

About jdeveloper

dear friends,
i would like to ask you about jdeveloper version 2.
i am trying to design & develop database that can be access from web brwser.(i.e put the database in the server and no software will be installed in the end user's machine. only the web browser).on my computer i have the following software installed:
1. oracle 8i enterprise edition release 8.1.5 for widows nt.
2.oracle developer and server version 6.0 for windows nt.
3.jdeveloper version 2 for windows nt.
my question :is jdeveloper the right solution to design a database that matches the above conditions?
and if so,can you give me the url of good sites to learn jdeveloper?
thanks a lot and have a nice day.
fatema alhassan.

hi don't know your name,
first of all you should post questions fro JD11 in this forum JDeveloper and ADF
To answer your question, it's all part of JD11, you don't need to download any extension.
From the menu choose file->new; in the dialog select General->Applicaion and click Ok. In the next dialog the part you are looking for is the Application Template. Here you can use 'J2EE Web Application' or 'Fusion Web Application'. Reed the template description to get some hints about the kind of application they are designed for.
