I have 3 apps developed in LWUIT using the Resource editor and adding more functionallity with Netbeans. I want to port them to codenameone. What is the best way to do that?
I see that the navite Componentsfrom LWUIT have an equivalent Componentin codenameone, but J2ME methods and classes , now have to be ported to J2SE, is that right?
The methods in the StateMachineBase have changed too. showForm() for example, doesn't exist now.What further changes are in StateMachineBase?
Thanks
Start by creating a new Codename One project then just copy your source code/resource files and fix the import statements.
You can't use the MIDP API's anymore (and you can't use J2SE either), there are new API's and a new lifecycle object which you can use for pretty much everything. showForm does exist and wasn't modified, I'm not exactly sure why you didn't find it.
Generally Codename One is much simpler since it doesn't have the project hierarchy issue and you don't need to deal with MIDP/RIM/Android differences. Its all handled for you.

I'm working on a product which is an RCP application based on Eclipse 3.x api. Now we are trying to move it to Eclipse 4.x. We are using some internal classes in our code. I've already read the tutorial provided by Vogella about migrating to Eclipse 4.x from 3.x, but I'm still not getting how to start.
We want to take advantage of the new Eclipse features, my main question is that we have good number of views, layouts in our old code, so what should be the approach I should follow. Also is there a way to create an application model from my older application using 3.x API.
I'm stuck and not getting how to proceed.
this really depends what you are trying to do. Do you just want to update your IDE? Or should the project be based on the e4 platform.
I recently updated a project from 3.x to the new IDE. This works very good, the compatibility layer does a good job and you are able to run the application with minimal changes. However if you do this, you cannot use the benefits of the e4 platform.
If you want to move your application to e4, thats more work to do. Mostly you will not want to touch all the old code, so there is a possiblity to have 3.x and e4 plugins run together in your application. Thats done with the e4 bridge and wrapper classes for old code. Most of the IDE views and editor are also still based on 3.x, so if you use them, the e4 bridge is also a good way to incorporate them.

I've read both the tutorial.But I am stucked and got too much confused as to where to start from. Basically 3 features are there
1. css styling of widgets(which i understood and did a bit of it)
2. to introduce dependency injection in my code
3. to put the application model
What approach I should follow?
This document helped me in deciding which strategy to adopt. http://www.eclipse.org/forums/index.php/fa/17403/ for migration.Indicates clearly which strategy you should adopt based on your existing code structure.Hope it helps
I'm trying to create my first xlet project.
Can you help me?
I don't know which library I need to download.
What kind of project I have to create? (I'm using netbeans)
This site has a lot of useful info:
http://www.interactivetvweb.org/tutorials/javatv/first_xlet
You can use XletView to view your Xlet.
http://sourceforge.net/projects/xletview/
You will need to get a hold on the various API's, which is somewhat troublesome (I've heard).
But there are also other ways of getting them. For example, if you own PowerDVD, you'll be able to find BDJ.jar somewhere in that package. Add that to your classpath, and you'll be able to compile your Xlet.
If you're running Windows, you can probably develop Xlets with JavaME SDK 3.0 too (sadly not available for Linux though).
I downloaded Netbeans 7.1 with all bundle from http://netbeans.org/downloads and installed it successfully on Windows 7.
But I can't find Java Desktop Application which should be under Java category when add new project as 7.0 does.
Where is it? Or what is the substitute one in 7.1? I need something to create GUI by dragging components.
Thanks.
Look here: http://netbeans.org/bugzilla/show_bug.cgi?id=204661
Support for [B]SAF (JSR 296, basically the framework that was behind your "Java Desktop Application" project template) has been abruptly dropped (for no valid reason, let me add).
However, as Bill says in his answer, it is not necessary to use the SAF in order to visually design a form. NetBeans swing-designer (known as Matisse) can be used to design any JFrame, JDialog, JPanel, etc.
You just have to
Right click -> New -> JFrame Form...
and you're ready to drag-and-drop!
(The features you'll be missing are the extra bells and whistles that such framework provided, like SAF Actions, windowing persistence, simplified management for long running Tasks and related visual feedback [now you have to get your hands dirty with the SwingWorker class], etc)
Java Desktop refers to an effort to create a standard or library (libraries) that never really produced anything of significance. I think its likely that they finally removed it from Netbeans.
Its easier to just create a new Java Application project, don't bother with a main, then create a new JFrame Form. That class will have a main for you to use, and you can also design the frame in the form. You can also create JPanel Form classes. Note: you can do this in just about any project in netbeans, there is nothing special about the projects for them.
its better to use NetBeans 7.0 for full support of swing components.
many tutorials and guides feature the "Java Desktop Application" (like the ones for JXMapKit : http://today.java.net/pub/a/today/2007/10/30/building-maps-into-swing-app-with-jxmapviewer.html )
You can find something helpful to create CRUD desktop application in Java.

I've build a static library working nice in a Cocoa Touch environment. Now I'd like to compile it also for Cocoa.. Can I have a single XCode project with different sdk targets? Is there some resource out there able to give hints about best the practices in this (and other) sense?
This last two months I have been working on exactly this task ( cross compiling static library for iPhone/Android/Mac OS/Linux/Windows...
It is certainly possible, a nice way, is adding an external xcode project as a target to your first xcode project. So you create a new "Active Configuration" for Mac OS X, iPhone and other platforms that you want to support.
Here, you can find a good tutorial about how to use a secondary Xcode project as a target of your main project to build a static library. It's a cool way because if you debug for example you still have all the symbols of the library, etc.
It can be done but it requires some manual tweaking of the build.
Start with the Xcode Build System Guide.
As an informal way of accomplishing this, you can create two separate projects and add references for exact same set of library source files to each project. Set one project to compile for Cocoa-Touch and the other for Cocoa. If both projects reference the same files, changes made in one project will be automatically reflected in the other. (If you have both projects open, Xcode will complain that the file has been changed by another app but otherwise it won't notice.)
I have a utility class that I continually dump new methods in. I add it to every project and just park methods as I need it. The new methods show up in old projects because the source files are shared across all the projects.
I am working on a number of iPhone development projects and I am starting to refactor code and would like to be able to package it in a library or framework that I can reuse in different xcode projects for different iPhone applications. I looked at the New Project dialog in xcode and the only option I have under iPhone OS is to create an Application. I have also read somewhere in the iPhone SDK documentation that I cannot create my own framework to reuse in different iPhone apps. What is then the best way to package my reusable components? I went over the iPhone SDK documentation and could not find out. I could keep all my reusable classes in a dummy project and link to those source files from other projects (so I would have a single copy of the source to maintain), but that feels very clumsy.
Thank you,

Create your common code as a static library.
Drag the xcodeproj file into the groups and files section of the project you want to use it in.
Update the include path to point to the headers of your static library.
In the info pane for the project you want to use the static lib in add it as a direct dependancy.
This process makes it almost as easy to work with as a regular framework.
Unfortunately Apple does not allow frameworks for the iPhone development at this stage. You can either bundle your code in a static library or just the source files in such a way that can easily use them in multiple projects.
I use SVN and keep my reusable code in repositories so that I can easily include them in new projects as externals
Apple does not allow to create own framwork. But you can achieve your goal by creating static libary.
Here is important link for kick off Static library.
