Eclipse differences versus JDeveloper

Folks,
Is there a rundown on the differences between developing using Eclipse and JBoss versus JDeveloper and OC4J, JBoss, WebSphere, etc....? Any pointers to docs or info. on the differences of what is available and not available via one ide and a deployment and the other?
I've read through various docs especially the developers guide and though it makes some references to differences it doesn't seem to be comprehensive. The problem is that I seem to be running up against a wall in building services that ought to be no-brainers as described by the doc., but that do not work as discussed or seem to be incomplete or missing altogether in the JBoss/Eclipse version of the development and deployment environment I'm using.
I may be just grasping at straws and there are no meaningful differences between the JBoss/OC4j/Websphere, etc... deployments and JDeveloper/Eclipse development environments but if there are I would appreciate not having to spend alot of time I don't have in figuring what those are on my own.
If there were a reference like a matrix that lined up the services available via one deployment versus another and via one ide and another that would be very helpful from the get-go as anyone could make alot of setup choices from that alone.
Thanks,

How to import existing eclipse Project to JDeveloper

Hi,
previously I used to use Eclipse IDE. I have started to use Oracle JDeveloper 11.1.2.4.0 now. How can I import my existing Eclipse projects to JDeveloper? Please Note, I already have tried following options -
"Importing Existing Files into a New JDeveloper Project" from here - Working with Applications and Projects.
But, When I import the source files from existing Eclipse Projects to JDeveloper, I am not able to crease similar directory structure in the JDeveloper(in Application Navigator). As a result, I can not use my existing ANT build script to build my project[Though JDeveloper build my project,but I want to use manual ANT build.]
Moreover I don't want to change my existing directory structure as I am working on and existing project and I need to synchronize to my repository(Apache SVN).
Can any one help me in this - How can I import existing Eclipse Project to JDeveloper? Without any significant change in directory structure.
Best Regards
Chandramoulee

Well there are two options - if you have a WAR file with the code in it, then you can use the file->import WAR.
Or you can use the new->Project from source code.
Note that you'll probably need to do some library settings and some directory setting after that.
Have a look at this demo for basic steps:

Differences between jdeveloper&jbuilder

Hello everybody!!!!
I'm trying to understand the difference between jdeveloper&jbuilder but.....no result!!!
I would develop a project wich should connecting on Oracle database and making statistics with data (it have been stored from file with SQLLOAD), and also it should read an UDP messages(port514) and store them to database ,so I can't decide wich programming langage to use...and wich are the better???
Thank you.

thank you for your reply!!!!
so I have installed an Oracle 8i on my PC(OS=XP Pro) ,and I think that is not possible to use jdeveloper (is it necessary to uninstall it and install Oracle9i?what I should do?)and I haven't a big knowledge about jdeveloper (making interfaces"Forms",writing SQL command,connecting to database,it's like developer2000 ?,and also the BIBeans should I install it or it's integrated with Oracle9i?(if you have an example with this tool please send it to me on my e-mail([email protected])and thank you very much
:-)))

Newbie: does ADF install/run with Eclipse instead of JDeveloper?

Hi,
Can ADF install/run with Eclipse instead of JDeveloper?
Thx
-Rob

If you mean can you design ADF applications with Eclipse then yes, you can do that with Oracle Enterprise Pack for Eclipse. It isn't as full-featured as the JDeveloper experience, though.

Importing eclipse projects to JDeveloper

Is there any way to import Eclipse project into JDevelper 10g?
Thanks.

Hi Shay, Frank
Our team is currently using Eclipse 3.1, struts and Oracle 9i DB, Oracle 10g AS to develop a mid size Java application. However we are running into serious constraint in our development as Eclipse does not allow us to debug for OC4J.
To avoid debug issues and associated time loss and inefficiency, we are trying to import the Eclipse project into Jdeveloper. When I import, it only imports the source files and not the associated libraries, config files, web content etc.
If possible please provide a step by step approach that we can follow to import Eclipse struts projects and then build it. If you can point us to some document, book, tutorial etc, it will be highly appreciated.

What is the difference between JDeveloper 9i & JDeveloper 10g

Hello All,
What is the difference between JDeveloper 9i & JDeveloper 10g with respect to OAF?
Regards.

The major differences I identified so far with respect to OA Framework..
1.Creating Business Component Package:
In Jdeveloper10g, there is no option to create business component package in right click context of project.
Rather, you can create a business component package by right click project --> 'New' --> web tier --> OA Components --> Package File
Give the file name as 'server' and give the package structure.
2. Path of deployment scripts:
In Jdeveloper10g, the path of deployment scripts like import.bat, jpximport..etc is <>jdev\jdevbin\oaext\bin instead of <>\jdev\jdevbin\jdev\bin w.r.to Jdeveloper9i

Migrating a Eclipse Project to JDeveloper and use it as a web service

Hi Guys,
I have a problem with migrating a Eclipse Project (EP) to JDeveloper. I know there are several threads about the problem out there but none of these fit my needs.
So, here is the problem:
I didn't had any problems migrating EPs to JDev in the past but this project is neither a .jar/.lib nor could I change it to one of those types. The project hase some additional filesto work. These files areare libs and owl-mappings for Jena/Pellet ( [http://jena.sourceforge.net/|http://jena.sourceforge.net/] ).
My porblem is that I don't know who to migrate the project to JDev and then use it as a web service, while the file structure stays the same plus everything is uploaded to Oracle as a web service. Meaning everything has to be included in one java package. Or am i wrong?
The file structure looks like this (from the EP):
src\*.java
owl\*.owl
lib\*.lib
location-mapping.n3
expdt.props
The Libraries aren't a problem. They are all .jar-files but could be easily included in the project (JDev) but I don't know how to handle the other files. Especially the much needed owl files :(
Maybe I'm doing it all wrong. My Goal is to use the EP as a web servies for a business process to enforce rulings and obligations. I'm kinda stumped...
Greetings,
Sebastian

Thank you very much, Shay. It helped regaining overview of the project files. Before all additional files were in the AppFolder.
I got to a point where I (hopefully) only got a problem with the directory matching (which is needed by jena).
Tanks again.
Sebastian

Eclipse plugin vs JDeveloper plugin

Hi
I recently installed the Oracle BPEL Designer Eclipse plugin and realized that it doesn't have the User Workflow extensions that the Oracle JDeveloper plugin has for almost a year. Any ideas when will the Designer plugin have the latest designer features.

When i import the source code and try to compile i get huge number of compilation errors as below. Below are only few examples. I have set the external libraries and jars for all the related projects. Any idea or pointers why the code with Generics has problem.
Thanks,
Krishna

Strange generic compilation behaviour - also javac/eclipse difference

Hello!
With my friends I've stumbled upon a problem in understanding how the compiler (and Java Language Specification too) treats a specific generic declaration.
public class Main {
    public static void main(String args[]) {
        ArrayList<Integer> inParam2 = new ArrayList<Integer>();
        List<Number> returnValue2 = justDoIt(inParam2);
    public static <E extends Number> List<E> justDoIt(List<? super E> nums) {
        return null;
}The code compiles fine with javac and throws compile error in eclipse. The latter, I believe, is the proper behaviour - what am I missing? The method justDoIt could be possibly resolved in two ways:
public static List<Number> justDoIt(List<Number> nums)or
public static List<Integer> justDoIt(List<Integer> nums)both will give reasonable and well-documented compile time errors. The first is because ArrayList<Integer> can't be passed to List<Number> (and even more - Integer is not a supertype of Number, therefore <? super Number> should fail). The latter is because List<Integer> value can't be assigned to List<Number> na main() for obvious reasons. I suppose from these two the compiler would resolve the mentioned static function as the one with Number throughout the declaration... but what really happens? How come the code compiles?
I would be very grateful for any insights.
Best regards,
Mateusz

I would be very grateful for any insights.*cough* I believe the relevant JLS section is this one: [15.12.2.7|http://java.sun.com/docs/books/jls/third_edition/html/expressions.html#341287]. I'll readily admit I felt a bit too flabby today to read all of it.

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.

Jdeveloper&eclipse

I have developed web services by using jdeveloper. Now I want to use eclipse WTP (as a representative tool of a open source world) to develop a client application. But i get errors :
1. as soon as i include wsdl file into my project, i get "referenced file containes errors (http://xmlns.oracle.com/jdeveloper/webservices)
Then i have decided to develop a new web service through eclipse wtp and in my class code there is an oracle connection. The web service is created but when i want to test it by Web Serviices Explorer and enter the appropriate values for the fields i get :
2. IWAB0135E An unexpected error has occurred.
IOException
Connection refused: connect
i can say that i am a beginner level user for these tools. What am i doing wrong? or is there any type of easy point that i am missing?

Problem creating WebDav connection to review XML schema in JDeveloper 10g

I am trying to review some XML schema and cannot seem to create a WebDav connection. I entered all the relevant info and keep getting the following error :Testing connection...
Connection test failed: unable to connect
Unable to connect to WebDav Connection1 (http://localhost:8080/)
May require proxy to connect to the location,
when I tried to test the connection. The tips given in the help section didn't work either. Could someone please help me?

Thanks for your prompt response.
I had done that before yet, it still doesn't work.
Please, bear with this newbie, for a second.
I think it may be relevant to mention that I am trying to create a connection on my local network.
Had no problems when I try to connect to enterprise manager,or iSQL*plus console, or creating a database connection through Jdeveloper, or even to the HTTP server through the browser. I am using windowsXP platform BTW, if it makes a difference, and Jdeveloper 10g. When I try to create the webDav Connection it still gives me the connection failed error, .....
