Choose a IDE

Should I choose JDeveloper or Workshop for weblogic application server and Java EE 5?
Thanks

If you wish to use an Oracle Eclipse IDE to build JEE5 applications, and assuming you have flexibility to choose the latest WLS releases, Oracle Enterprise Pack for Eclipse (OEPE) is the recommended option. It supports the latest releases of WLS - WLS 10gR3 (aka WLS 10.3) and WLS 11gR1 (aka WLS 10.3.1) and is the going forward Eclipse-based development tool for JEE applications on WebLogic Server. WebLogic Workshop is not supported on WLS 10.3.1 for development of new applications and is only supported for migration purposes from prior WLS versions.
JDeveloper supports these WLS releases as well as David mentions, and supports development of applications on the full Fusion Middleware Stack.

Best way to implement tree like subcategory chooser in GUI on iphone

I need to let user choose subcategory, from a tree like structure, 3-4 level deep.
and the list is veeeery long. I was wondering what would be the best way to show it to user, and let him choose one.
ideas ?

The right solution here is probably a set of UITableViewController subclasses inside a UINavigationController that your application presents modally. If the lists are long even within a level, sort and group them alphabetically and present an index list along the side, the way Contacts does. You should be able to do all this with just a few UITableViewDelegate/DataSource methods.

Do you store IDE-specific files in your repository?

Hi ,
In [Continuous Integration|http://martinfowler.com/articles/continuousIntegration.html] , The author state that
"You must put everything required for a build in the source control system, however you may also put other stuff that people generally work with in there too. IDE configurations are good to put in there because that way it's easy for people to share the same IDE setups."
This is quite contradict with my personal believe that IDE-specific configurations shouldn't be check-in to source repository. Doesn't it mean that team members have no freedom in choosing their IDE? Even they agree to use the same IDE, how can you manage the compatibility of IDE configuration files across various versions. Different team members may prefer different version of the IDE. Even with the same version, the IDE configuration files are very easy to get modified by all sort of actions. Do all those changes should be check-in to the repository?
I am re-organizing my repository so I am interested to know whether you keep your IDE-specific files in your repository. If you do, please share with me how you deal with the above problems.
Thanks very much

The story:
A programmer left the organisation about two years ago. Part of the exit process is to totally wipe the harddisk (stored passwords, history, etc, etc). We lost the only working ant-build-scripts for our production branch... Not long after that the decree came down from on high that every-single-iddy-biddy-farking-file used to build the sucker WILL BE IN VSS.... ABSAPOSITIVELY NO EXCEPTIONS!
I for one agree whole heartedly with that decree, because I was the poor noobie (as in new to the job, java, weblogic, and web-apps) who having just sat in the nice hot seat, had to learn all about "building big complex java projects" really farking soon now, like yesterday... it delayed the release of a "critical" production patch for a month... after two weeks of me trying to get it building (with no real end in sight) we stripped all the high/medium risk RFC's out of the development branch, tested it double time, and shipped it.
It's not fascism... it's professionalism.... McRisk McManagement.

IDE over SATA for Boot Drive

If I have an IDE HD (Hitachi Deskstar 160GB) install along with my WD Sata 250 my BIOS always chooses the IDE drive to boot from. When the IDE drive is detected the sata does not show as available.
How can I have both installed, but boot from the SATA?

Quote from: Maesus on 12-January-07, 22:56:07
can you change the HDD sequence in the BIOS ? Pick the HDD you wanna boot as the 1st HDD.
No, I cannot choose the HDD. If the both the SATA and IDE is physically installed, the SATA does not show .
However if I press F11 during the boot, both the ARE listed. Using F11 to boot, I have booted from the SATA. The IDE shows in WinXP as a "disk drive." I rebooted to see if any subsequent boots would you the SATA (thinking that the F11 function sets it as default), but the boot was with the IDE.

JDev and ADF is difficult

As a new user to ADF I am finding ADF and JDev a little discouraging and hard to use. I did a search on how to improve jdev's performance and found a lot of useful tips and tricks to use, but I pose the question. Shouldn't it just work out of the box? Coming from a web 2.0 background developing EE applications using Spring, JPA/Hibernate, Extjs, and netbeans I keep thinking to myself wow how in the world should I have known that changing this or that table attribute causes this or that to behave differently. For example I read a thread on multi-selecting table rows and in this article multiselect selectedRowKeys must be removed for multi select to perform correctly. Now I realize this is a simple example, but I find myself asking the same types of questions about dragging and dropping views into jdev or mapping bindings to pages so that I can gain access to data. I can relate to some angry posts by some about how difficult it is to develop anything useful in JDev and ADF because of a series of random problems (things like running OOM, or mapping bindings to a page which then for some reason map incorrectly or they think they are mapped to another page, etc...) Now I can already hear the first response... you are new to this world (yes) and you just need time. What if I told you I've been reading so much documentation over the past month that my eyes are bleeding. I've been through countless tutorials on how to use JDev and ADF. I've successfully created "Sample applications" generating useless tables of data. I've read several books on ADF and how to button click my way to creating EE applications, but I find the memorization of button clicking to be exhausting. I keep telling my boss I want to go back to writing code not dragging and dropping items on a page so that JDev can generate/modify .xml files for me.
Now that said I know I am new to this world and I'm trying to find some common ground as my job requires me to develop EE applications in ADF, and I must learn this technology. So I ask all of you ADF and JDev advocates prove me wrong here and point me to the documentation that all of you use to navigate this world of yours.
Thanks for your understand,
Wraith (Newbie and found wanting)

First off thank you for the response Shay!
>
Getting used to the way you build applications with JDev and ADF takes time, but think how much time did it took you to learn Spring, JPA, ExtJS etc to a level where you knew every little setting you needed to manually code in a spring XML file, or JPQL query syntax in your JPA or a javascript in ExtJS - My guess was that getting to a situation where you know everything in those technology wasn't exactly a problem less experience.
>
It is true it took some time to learn the technologies listed above. I guess If I were arguing for them I would say they were easier to use and learn due to most of them being open source and very popular because of this (i.e tons of examples, books, and documentation). Not sure if ADF is there yet?
>
I do like the fact that I can get from 0 to a fully functional page with a few clicks here and there, and then fine tune the results with some property settings in various places.
And then if I need even further customization I can go to the code level when needed.
>
I agree it takes very little time to create something that is at least visually usable. I'm not familiar enough ADF yet to determine now hard it is to actually create a fully functioning application that does more than display data. For example, how would I create a visualization that updates every 10 seconds and allows users to post feedback in a similar manner to this forum?
>
The question of whether the declarative and visual development experience is a good thing or not is to some degree a matter of personal preferences.
I wonder how long would it have taken someone to build something like this: http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/ADF112/ADF112.html
with the stack you mentioned above. How many lines of code would they have needed to write, how many syntax errors while coding, and would the result be as functional so fast.
>
Agree I'm not hear to argue which type of development experience is better or worse. I would point out however that as a JDev/ADF developer in order to develop in the technology it seems you must do most of your development within the JDev environment or have extensive experience in JSF (i.e know which xml files to edit and why I believe there is a reason JSF and JSP are seldom used IMHO because they are difficult. I understand JDev/ADF try to solve this problem) were as in other technologies you as the developer can choose the IDE etc. Another thing I noticed while watching the link you listed was the developer went from place to place to place within jdev making changes. As a newbie it seems that in order to develop ADF in JDev you must just "know things" (ie. for example he pulled in a method in to the task flow so he could invoke some validation or prereq check. As a developer how am I to know how and where and why I can/must do these things? ADF seems to be process based in order to achieve some goal, but the JDev framework gives no clues as to what you should/need to do next. As well as that I needed to create that method within my Application Module in order to do this, which by the way was not mentioned within this video.).
>
We often see the reaction of "I don't get what all those XML files that JDev generate are doing" reaction from people who just start up with JDev and ADF.
But we do try and explain how everything is working in places like the ADF Insider Advanced seminars:
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/adfinsider-093342.html
I think the fact that there is a lot of documentation for ADF, and a lot of blog entries, how-to's etc on the web is actually a good thing.
I often find that if I run into an issue with ADF - a simple google search will show me how someone else solved that issue - and I like this too.
>
I guess my biggest gripe here would be yes there is tons of JDev/ADF documentation on OTN and other places, but none of it is complete, and I would also argue that the organization on OTN is half hazard, and makes learning ADF difficult as well. I find myself drilling down through layers and layers of links only to not be able to get back to were I came from to look at another topic/tutorial I was interested in(maybe we need a ADF train to be added to the documentation wikis).
I would also argue when developing in other frameworks writing the xml is a big part to understanding how your application is tied together. For example, Spring servlet mapping or Spring injection mapping. When JDev does the mapping for me I feel that I know less and less about how my application works and I bet all the advanced ADF developers out there know quite a bit about how ADF xml mapping occurs and why, and I bet they make changes to these xml files manually quite often to get things to work as they desire?
I want to be clear here I am not trying to flaming here, just trying to make a difference for other developers like myself who come along and need to learn ADF to complete some task. Looking at the OTN site I believe creating documentation for ADF development appears to be a top priority, but due to the complexity of the framework there is just so much and it seems to be everywhere. My suggestion would be to include why we are doing such and such with in jdev approach instead of a drag this here to do this approach. For example, I'd like to see a tutorial where it explains when you drag this item in to the content window it creates this xml bind which is the same as what you would normally do in JSF like this (if anyone knows of such a tutorial plz link).
Again thanks for the reply, and I encourage others to give feedback and suggestions on how I too can become a better JDev/ADF developer.

How do I get back the default skyline Y450 7 wallpaper

I just got a Y450 yesterday. I installed Win 7 Home Premium. It came up with this cool skyline wallpaper that changed as the day got later. It started out sort of orange with the sun up and during the day the sun went down, then a blimp came across the sk,y and by night the wallpaper turned blue and there was a moon in the sky.
So my problem, I was playing with the slidenav and it changed the cool wallpaper to one of the installed pictures in the picture library. When I went to put the default paper back that was first installed I couldn't find it. I spent today loading additional software and looking for that wallpaper. I thought I had it last night when I was able to go to the guest account and save the theme, but the only thing it did was save the night picture and it never changed today.
Anyone know how to get the originally installed wallpaper back? Where'd it go?

After you click Personalization, click on the Desktop Background icon on the botton (next to Window Color). In the new window, choose Alive Idea Desktop for Picture Location. It should be located there. It was where I found the theme again.

ADF application deployed to Weblogic producing runtime error

Hi all,
We are trying to deploy a new ADF application built by JDeveloper 11.1.1.5.0 to a standalone weblogic (*version 10.3.1.0*)
The app deploys and runs on integrated wls without any problems, and deploys to the standalone wls without any warnings or errors, but does not run on standalone wls :(
I checked many possible errors and tried many possible solutions, including, but not limited to;
--> Checked tag references and page components on jsp/jspx pages, deleted unused or possibly unsupported tags from pages and taglibs from ui project (trinidad components 1.2), but still I get the error
--> Using 2 different machines with JDev 11.1.1.5 we created test applications with same tech stack, tag libraries and tag references, deployed to standalone wls and they run without problems (!)
--> Checked web.xml, the file contents and references are the same as of other applications whic are deployed from same environment to the same standalone wls and running without problems (these applications are referenced as "other working applications" following this line)
--> In sessions.xml, the db connection is default, the file includes 2 references <server-platform xsi:type="weblogic-10-platform"/> and <primary-project xsi:type="xml">META-INF/tlMap.xml</primary-project>
--> All projects (Model and view) are cleaned and rebuilt, deployment files are recreated, application ear is recreated, runtime application name and context root name ise changed, but still no luck, I get the same error
--> Project technology stacks are checked and all tech stacks are configured same as "other working apllications" (since their technical architectures are the same)
--> Checked application datasources; database connections of this application automatically create datasources, for connection dbconn1 there exists a datasource named dbconn1DS as a module in the deployed application. Other working applications had datasources with same name; to prevent a possible conflict in JNDI names of these datasources I changed the name of the db connection to a unique name, deleted the old connection and datasource. But still no luck, error is still SAME.
--> Test applications (which have trinidad components 1.2 as tag library and there are references to it from page files) run on standalone wls, removing this taglib and the references does not make a difference. But the real application gives error when trinidad is removed from the tag libraries (java.lang.NoSuchMethodError: resetADFContext)
--> Created new jspx pages which are not using backing beans and tried to access these, but I received the SAME error for these pages as well. Removed all jspx pages except the dummy test pages, and still no change.
One final note; html pages in the project open without problems, as their url are different from the jspx files ( "host/appName/Test.html instead" of "host/appName/faces/Test.jspx" ) and when these pages open, the server log and console indicates new sessions created by this request.
This is the famous error I get on the server log every time I try to access a jspx file:

Could anybody please help, where to focus to see the REAL indications and solutions of this annoying error? Soon I will get this application to production environment, so any help would be appreciated.
Thanks in advance...

Ok, I think I should give the update, on how I struggled to solve the problem;
--> I did NOT update the wls, since it is the production server and has many applications and services running on it , I could not take the risk of breaking those.
--> I migrated, or rewrote the application on JDeveloper 11.1.1.1.0, rewrote the toplink map file, descriptors, pageDefs bla bla, to make it compatible with wls 10.3.1.0.
--> Then I tested the app on JDev 11.1.1.1.0 ok, then opened the same application on JDev 11.1.1.5.0 then tested ok....
--> And I deployed the application from JDev 11.1.1.5.0 to the standalone wls, and this is where the magic happened, the app worked without error on standalone wls 10.3.1.0
+( Just a note: I really wonder, where is the backward, or forward compatibility of ide and server runtimes? )+
Anyway, it is a big lesson for me about choosing the ide version for a specific server.
Thank you...

Should I write in Flash Professional or Catalyst?

I have Adobe Design Premium CS5. I'm about to write a simple file web based SWF uploader (with chunking). Should I write my uploader in Flash Professional or in Catalyst, in Flash Player or in Flex. I'm confused, heck I do not even know which Adobe forum to post this question to :-(
Can anyone point me to a list of simple heuristics to help me choose between IDEs and SDKs please.

Just do it in Flash CS5.5. Sounds like you have no experience with Flash or you wouldn't be asking this question. There's no point in getting the Flex framework involved. You could use Catalyst to prototype the UI and then use Flash, but I wouldn't bother.

How to get start CDC with Windows Mobile 5

i have bought new PDA (imate K-JAM) and want to develop CDC on it but i don't know what i need for develop it
i found this site (http://home.elka.pw.edu.pl/~pboetzel/) i need to download all require software ? if no please tell me what i need to download ?
thank you!!

Hi ekkapop,
First you need to find a JVM that support CDC, here are 2 of them for Pocket PC:
-IBM J9
-Creme
Then choose the IDE of your preference (Eclipse, Netbeans...)
I order to keep the best compability use only AWT components and compile with javac 1.4 or lower and jar your project.
It should run just fine on thoses JVMs.
Now this is the way to keep simple, then you can try adding swt or swing libraries to enrich your project and try other packs for IDE.
But using awt components and compiling with javac 1.4 have worked just fine for me.
Now I am also beggining with the J2ME so this is just the first feedback I can give for now.
Regards,
Romain

Mark,
The OCI drivers require some client-side software. The version
of the OCI client must match the version of the OCI driver you
are using from JDeveloper rather than the version of the
database you are connecting to.
For example, if you are using the 8.1.5 JDBC OCI8 driver to
connect to an Oracle 8.0.5 database, then you need the OCI 8.1.5
client running on the same machine as JDeveloper.
The OCI client software is included in the server distribution
(if you have the database running locally), or from the Oracle
Client software distribution.
If you have either of the above installed locally, then make sure
that ORACLE_HOME is set to the correct location in your
registry.
This is what JDeveloper uses to find the ocijdbc8.dll.
If you have multiple Oracle Homes, you can explicitly set which
one to use from JDeveloper by choosing Tools|IDE Options from the
menu. Click the Environment tab, and choose an Oracle Home from
the drop-down list.
The JDBC thin drivers do not require this client-side piece.

Bit of an arbitrary way to choose an IDE, though. Anyways, the Eclipse goal for Maven always works for me. No tiresome importing of dependencies, no downloading third-party plugins, nothing. Just run mvn eclipse:eclipse and it works. SimpleWhere I'm going to run that "mvn eclipse:eclipse"? Same place you run any other Maven goals. A command-line, where the root pom.xml of your project is
Out of topic question: Can I create my class diagram in Eclipse? Or if you know any third party softwares to do that with relationship detector? ThanksThere are tools to do it, yeh. Don't know what they are though

Type tool support, or notepad?

Is it possible to include a type tool or a notepad function to Adobe Debut?
I love the idea that it optimises files for display on the tablet without having to convert to images, and the idea that we can take notations is great. However there is the problem that writing notes on a tablet delivers poor results.
Would it be possible to have a type tool included soon to fix this issue?
Or perhaps an in-file notepad that attaches to the item you're working on and exports as annotations in a PDF?
If I'm showing a designt o a client I'd like to be able to take more extensive notes on the actual file instead of a notebook with me. Otherwise we're all spending $10 on the app and hundreds of dollars on the cloud that could have been spent on a printer and some pens.

You should use the Create Idea function of this forum to make your wishes heard. Just check under Browse and choose Ideas. Then, in the upper right-hand side of the page choose Create Idea.

[Arduino] Best tools for Arduino development

Hello,
The IDE doesn't looks like it fits my needs I'm looking for a more Arch Linux/KISS way to play with my Arduino.
Basically I would like to use the editor of my choice and use some build/upload scripts.
Any advices, recommendations?
Thanks.

I'm not familiar with any other way of working with Arduino code than using the IDE, however if you are feeling somewhat adventurous, you can always use the gcc-avr/avr-libc toolchain and write code for the micro-controller in C. This is advantageous as you would be free to choose the IDE or text editor of your liking for creating the software, and by familiarizing yourself with the C language, you may advance to writing code for other micro-controller platforms.
The down side of this is that you are loosing all of the "rapid and easy" development awesomeness of the Arduino language.

(cannot connect jdev2.0 with oracle 8i) #2

In reply to the question i have Oracle 8.1.5 and NT 4 with SP5. and JDEV 2.0
thanks

I guess I should have also askced you which driver you are using to connect.. thin or OCI.
First thing you should do is select your project and choose Properties from the right-mouse menu. Make sure 'Oracle 8.1.5 JDBC' shows up in the Libraries list. If it doesn't, choose Add to add it.
If you are using the thin driver, try using the Named Host method of connecting (rather than existing TNS Names). This method does not depend on an external Oracle Home like the TNS method does.
If you do want to use the TNS method, choose Tools|IDE Options from the menu. On the Environment tab, you can explictly set which Oracle Home to have JDeveloper look for the TNS entry.
Also, for the thin driver, check the Oracle 8.1.5 JDBC User's Guide and reference. There is a section in Chapter 1 or 2 which provides sample code for testing a JDBC connection from the command line.
If you are using the OCI driver, and your database is on the same machine that you are running JDev from: make sure that the Oracle Home JDev is using is the one where your database is installed.
If you are using the OCI driver and the database is on a different machine, you need to install the Oracle Client software that matches the version of the JDBC drivers you are using (by default, 8.1.5 in JDev 2.0 and 3.0).
