I have noticed that Oracle now has released a Java Platform Micro Edition SDK for OSX. It works, it can compile the provided examples and the included phone emulator works too. But how do I compile my own J2ME project from Ant or Eclipse?
There are a lot of related jars but they are all inside the ".app" in the /Applications directory. Eclipse does not like it when I put a toolchain path to inside the ".app".
Have you tried using the EclipseME plugin? It helps integrate JavaME (J2ME) development into Eclipse. Here's a guide for getting it working with Eclipse:
Eclipse ME / Configuration
You'll find plenty of documentation and how tos.
If you don't like EclipseME, I personally found Netbeans very good for mobile development:
Netbeans JavaME Page
Also, you weren't specific in your question, but the link you've provided seems to indicate you want to use MTJ. In that case, use this documentation to guide you through:
Eclipse MTJ - Getting Started
If you want to use ANT I have simply copied over the required jars from the Windows SDK and just used the pre verifier and javac from the osx 3.0 sdk, works well!

I received a full working project's sourcecode for an app written in java.
to set up my win7 machine I followed these steps:
http://www.javacodegeeks.com/2013/03/setup-your-java-development-environment-in-windows-7.html
i opened eclipse and need to work on this project, but have NO idea how to pull in the project with all its files so I can actually run it and test it.
I need to make changes to this project.
the folder is located in MyDocuments folder called Budget
within Budget I have:
.metadata
dev (see screenshot of what is in this folder)
can some one help me setup everything? I have never done this, I am only familiar with XAMPP
i also looked at
How to open an existing project in Eclipse?
i tried it and get files and filders in the navigation pane, how from here?
What you have installed is JavaSE SDK plus a lot of other stuff for regular Java development. But in your screenshot I can see that your project has a Blackberry and Android versions. To develop in these platforms, your Java SDK install is not enough. You'll need to setup both BB and android development environments in your machine. You'll probably need:
For BlackBerry:
Blackberry Java SDK (check which version was the BB subproject made for)
Eclipse with BlackBerry Java plugin. There used to exist eclipse versions with the BB plugin already installed available for download in Blackberry's site. If you don't have one, this is the one you want. And if you already have an eclipse, resist the temptation to just add the BB plugin to it. The BB plugin messes up with almost every other plugin you might already have. Also each plugin was made to a target eclipse version, so just download the bundled eclipse+plugin from BB and be happy:
http://developer.blackberry.com/bbos/java/download/
Also some simulators for your target platform. I think the eclipse plugin comes with one already installed. They are really slow though, so you might want a real device instead.
For android:
Android SDK
An eclipse with the ADT plugin, if the project was made with eclipse, or the newer Android Studio. This eclipse plugin is better made than BB's so you won't need a dedicated eclipse like in BB's case.
Simulators are made with the ADM tool included in the SDK.
Good luck!
I have been trying to setup LibGDX on Eclipse (4.3). I followed the instructions here: https://github.com/libgdx/libgdx/wiki/Prerequisites and installed both ADT plugin for Eclipse and the Google Web toolkit successfully. Then I used the libgdx-ui.exe to create the libGDX project and on creating it, I see errors in Eclipse.
I am pretty sure I have installed the plugins properly and I have JDK 7 as well.
Any help would be greatly appreciated.
Thanks :)
It seems I have not installed the GWT plugins properly. But on trying to install it from the link, the option to install the SDK does not appear in the list.(Please check the image in the last comment I posted).
1) Android requires (before kitkat) jdk 6. It won't work with jdk 7.
2) After installing ADT plugin, you also have to open android sdk manager and download required api files.
These two should fix your android and java.lang.Object issues. It's better to test an android app on this setup (without libgdx) first.
3) Right click on all warnings regarding classpath entries, eclipse will provide you automatic quick fixes.
If the issue stays after this, the problem is with gwt sdk installation. Now you can follow The project XXX does not have any GWT SDKs on its build path. It should work smoothly as other problems won't interfere with it now.
Hope this helps.
I read Lars Vogel's Android Development tutorial and then headed directly to the Android SDK download page.
I already have the Eclipse Java EE IDE (Juno; 4.2) installed, and would like to only install the Android SDK and then the ADT Eclipse plugin so I can start working from my existing Eclipse instance. As such, I downloaded the 64-bit linux (I'm on Ubuntu) "SDK Only" .tgz and extracted it to the my ~/sandbox/android-sdk directory.
Before I go and install the ADT Plugin, are there any "setup"/config steps with the SDK that I need to do ahead of time? If so, what? I'm even interested in optional tuning here. I only ask because the article referenced above is targeted at Windows users, and so are most of the other tutorials I've found. I'm worried that there might be some out-of-the-box functionality that the Windows SDK provides that must be dealt with manually for us Linux denizens. Thanks in advance!
From my experience, I believe the answer is no, there is nothing else you need to do before installing the ADT Plugin. If you wanted, you could open the SDK manager from ~/sandbox/android-sdk/tools/android and install some of the SDKs, but there's no reason you can't just do that from Eclipse after you install ADT.
im starting developing android applications and i learned from a Hello World tutorial. but when im running it this comes to the screen
Launch configuration ANSIBuffer references non-existing project Basic.
Please, help me and tell how i can run a android application.
Thanks
I would recommend downloading the official adt (android development tools) plugin for eclipse. You can find instructions on how to do that here: http://developer.android.com/sdk/eclipse-adt.html you need to make sure that you have the most recent version of android sdk installed before you do that. Instructions on how to install that are here (this includes a eclipse tutorial): http://developer.android.com/sdk/installing.html
I believe that that is all you need. Just ask if you need more help!
I did a guide once for a course, but it is in spanish:
http://otfusion.org/android/ (look for day 2)
But basically the guide is this:
Download JDK from here: Java SE - Oracle
Download Android SDK (.zip format, just unzip it in C:\android-sdk or if you are in *nix /home/user/android-sdk) from here: Android SDK - Developer Guide
Start ~android-sdk/tools/android and download your desired android target (eclair, donut, honeycomb, etc)
Download Eclipse for Java Developers* (as far I know, the latest eclipse WORKS on my notebook) from here: Eclipse - Indigo
Install eclipse in a readable/writable location like /home/user/bin or /opt/eclipse but give permission to the file - chown -r user:users /opt/eclipse (in Windows you must not have problems) otherwhise you will have problems.
Install ADT Plugin just add this site in Eclipse "Add Software" option (Help menu) https://dl-ssl.google.com/android/eclipse/
Restart Eclipse
Start one AVD and initiate your project using the Run button (As Android project) or whatever hotkey you use.

How do I find which Eclipse version I have on my Ubuntu system?
This is what "About Eclipse SDK" says.
Eclipse SDK
Version: 3.5.2
Build id: M20100211-1343
I am not sure if its the Eclipse IDE for Java Developers or the Eclipse Classic version.
What I would like to do is use Eclipse for
Java based Web Application Development
Ant Builds
Deploy using Tomcat
including HTML, CSS Editing
Please help me decide which version I should choose? I would like to upgrade my Eclipse setup from whatever version it is now to a version that supports all the above. Should I go for Eclipse IDE for Java EE Developers?
Should I download a totally new version from Eclipse site or can I just ADD necessary features/plugins to my current Eclipse setup.
Please suggest.
See Compare Eclipse Packages for a nice chart
What I would like to do is use Eclipse for (...)
The Eclipse IDE for Java EE Developers allows to do what you're asking for out of the box.
Should I download a totally new version from Eclipse site or can I just ADD necessary features/plugins to my current Eclipse setup.
Both would work, although it would be simpler to just get directly the Eclipse IDE for Java EE Developers (especially if you don't know exactly what plugin(s) you're looking for). Personally, I don't use the version you can get from the repository but download Eclipse from the official website and install it in user mode.
If you are using Eclipse for only Enterprise Development, then as everybody has recommended I would use the Eclipse Java EE version. If you plan on occasionally using it for other development purposes then I would consider downloading a separate classic version as well.
The reason for this is that everybody is well aware of eclipse's plugin capabilities. Unfortunately, Eclipse can get bogged down with too many plugins or add on tools. What I have experienced is that if you are using it for Enterprise Development(J2EE) it might be a good idea to keep that as a separate environment then your other Java Development. That way you can download the plugins,tools,libraries,etc for your enterprise development, and you can use your classic version for any other development you might need.
The downside is you will have two versions, but this is not a problem granted you do not run them simultaneously.
If you want to play with Web development, then the Eclipse java EE for Developers is for you. It is shipped with components to make Java Enterprise applications to create Enterprise Applications (and bundle it in an Enterprise ARchiver, known as EAR file or Web ARchive, known as WAR file).
The default Eclipse shipping with Ubuntu is the Classic version, and you can add more plugins.
I would recommend, however, to download th eJEE version manually and unzip it and run. Then you have a local installation outside the system files.
