I'm trying to convert an existing LWUIT project to Codenameone. I copy the sources and resources to a new j2me project I add the codename1.jar to the libraries of the project then I fix the imports in my source and every thing seems to be ok but when I run the midlet I get this:
No Class Def Found Error java/lang/NoClassDefFoundError com/codename1/impl/ImplementationFactory
is there a missing thing in the library?
I'm using codenameone as a library ,i dont use the designer.
am I doing some thing wrong?
You need to use the Codename One sources from SVN and compile the MIDP port of Codename One to build a native J2ME application.

I'm using play framework 2.1.1, and I want to add to a project restfb in order to use Facebook graph.
I added restfb-1.9.0.JAR to eclipse, then I right clicked on it, and chose build path->add to build path.
However when I'm trying to write some code, and use the restfb package, I'm getting an error code on the browser.
This is the error:
error: package com.restfb does not exist
On the line:
import com.restfb.FacebookClient;
Any idea on how I can fix this?
Thanks
Copy your libraries into the lib folder in your project folder. If the lib-folder does not exist, create it.
The Play Framework includes all jars in the lib-folder when building/compiling your app. Adding it to the eclipse-build-path is not enough.
I am using libgdx to make a ios game with RoboVM. I am using the latest versions of LibGDX, RoboVM and my Eclipse is up to date.
Recently I have been trying to add Google Analytics thanks to the Robovm bindings.
I have manually imported the analytics project in Eclipse:
with File -> Import -> Gradle project
Everyting works fine, I can import and use the classes in my ios project.
But then if I right click my ios project -> Gradle -> refresh all, the build is succesful but it removes the analytics project from the java build path. As a result, when I try to compile my ios project from a terminal with a command line, it doesn't compile since it doesn't fine the analytics classes. I am using "./gradlew -Probovm.device.name=myiPhone launchIOSDevice --stacktrace"
I guess there is a setting or property in Gradle or Robovm that I should change, anybody has an idea?
Answering to myself, it might help others... I ended up creating my own jar from the analytics project, and added it as a library in a separate folder. As described here: https://github.com/BlueRiverInteractive/robovm-ios-bindings/blob/master/README.md
This way every new Gradle build correctly links it to my ios project.
I am developing an video calling application using javafx. And I need to integrate jitsi video GUI into javafx Swing node.
Is it possible or Do I have to use 'libjitsi' and implement GUI in javafx ?
Any suggestions would be appreciated.
If you're asking about how to embed Swing content into JavaFX, you can use a SwingNode.
It worked for me (I added a Swing PDF player in a JavaFX application)
Here is an example of how to perform this : http://docs.oracle.com/javafx/8/embed_swing/jfxpub-embed_swing.htm
This might be very late but still, I am posting the answer as seems to be a genuine question.
To use JavaFX with jitsi, developing with eclipse steps are as follows.
First, you require to install an addon of JavaFX in eclipse e. g. EFX
After adding above addon add JavaFX SDK to the project. The link: https://www.tutorialkart.com/javafx/install-javafx-in-eclipse-ide/
Then add the package entries to the manifest.mf files {in the package where you are executing} and felix.run.properties file.
And the project will run smoothly. Another thing if using a class with the superclass of Application then keep it in the different jar file add the entries of the jar to the build.xml(in copy jar section) and add the package entries to the manifest.mf files {in the package where you are executing} and felix.run.properties file.
I have a java based appengine endpoint project in eclipse.
When I generate client library using command line tool.
https://developers.google.com/appengine/docs/java/endpoints/endpoints_tool
I'm getting only source based jar file ('project_name_version'.java-1.18.0-rc-sources.jar). It does not work fine in Android Studio when I add as a Library.
How can I get class based jar client library (google-api-services-'project_name_verison'-1.18.0-rc.jar)?
I tried searching online but no luck yet.
You could always zip up the sources file and use them in Android Studio. However , note that in the build.gradle file, you will have to reference the other dependent JAR files + versions that will be needed by the sources that you have generated in Eclipse via the Generate Cloud Endpoint Library option.

I am developing a project on Eclipse Juno using both GWT and GAE.
My original project had all its packages and classes on the same project and it worked fine both on Development Mode and when uploaded to the Google App Engine on the Internet.
Then I created another project (on the same workspace) were I moved the classes that were generic so they could be used on other projects. I have not created a Jar file. Do I have to? I wish I could just keep my generic classes on another project without putting them on a jar file.
After a while I was able to create correct XXX.gwt.xml files on both projects and added the new project to the "Projects" tab of the main project properties (Project >> Properties >> Projects) to make the moved classes visible to the main project. The GWT compiler found those moved classes, translated them into Javascript code and the main project was able to execute them on the client side.
My problem is on the server side. No matter what I try the server part cannot find the moved classes and when trying to execute any of them it comes with the "NoClassDefFoundError" error when running on the Development Mode (I have not tried to upload to the Google App Engine on the Internet yet).
If I comment out all the references to those classes on the server side the error does not show up, but of course I don't have their functionality.

Yes, you'll have to create a jar of the second project, and put it in the WEB-INF/lib folder.
If you can use maven or ant, you can probably set up appengine to compile the other project into a jar and use it as a dependency for the app engine project.
