I'm wondering if I can import NetBeans projects (especially desktop applications) into Eclipse, that I have a NetBeans project which is a desktop application and I want to run it in Eclipse.. is that possible ? because I've searched, but no clear answers has showed up :(
Info :
Platform : Mac OS 10.6.5
NetBeans : 6.5
Eclipse : 3.3.2
Java : JDK 1.6
Thanks in advance
When you say Desktop Applications it sounds like you have designed the GUI using the Netbeans tools, and the generated Java files should run nicely, but you will not be able to edit them freely and expect Netbeans to like the revised files when you import them back.
SO, in other words, try and see what happens.
Sure, Netbeans and Eclipse are both just IDEs, so you can move code from one to the other easily. The folder structure they use may be a little different, but you should be able to just import the .java (or whatever other language you are using) files.
Create a new project in eclipse and import the *.java files !
Here is a great article on "How to import NetBeans project into Eclipse". I personally found method #2 to be more useful.

I've been looking into scala lately and from the conciseness and language features I'm completely thrilled.
I have netbeans 8.0 running on ubuntu 12.04 and downloaded scala, edited netbeans.conf (netbeans_default_options="-J-Dscala.home=...), installed plugins from plugin manager inside netbeans (ALL OF THEM). Then, I created scala project (not maven one) and tried out autocomplete. It works, compiles, runs, however, it shows no document found in autocompletion.
This is how I added javadocs Tools > Scala platforms > javadoc tab
I tried adding following ways:
added the entire scala api doc zip from http://downloads.typesafe.com/scala/2.11.2/scala-docs-2.11.2.zip
extracted the previous zip to scala-home folder under $SCALA_HOME/docs/javadocs/scala-docs-2.11.2 and added that
same as 2 but added $SCALA_HOME/docs/javadocs/scala-docs-2.11.2/api in netbeans
None of these pick up documentation! Of course, I could live without it, but it's such a killer for such a concise language where I could just find out stuff instantly from autocompletion. Also, I don't want to use eclipse special ide for scala because I don't want to throw out all the experience with netbeans out of the window and learn new IDE.
P.S. - Netbeans navigator also seem not to work in scala.
And I wonder why there's so little content on google for such a wonderful language?
There is no need to change to IntelliJ. Use the right build tool -sbt or Maven- and everything works fine.
In Netbeans you can use e.g. free Application Servers.
Netbeans support for scala seems pathetic so I just decided to jump to IntelliJ IDEA. It was little bit of learning curve but I'm glad I did because now everything was working (autocomplete, documentation, awesome SBT support etc. etc.)
I have a project, we want the SWT/JFace GEF Eclipse plugin project independ from Eclipse IDE. for example, as a java project, we import the java libarary, and run the java application as normal, could anyone help me to give me an idea. Many thanks!
You have to write an Eclipse Rich Client Platform (RCP), this includes enough of Eclipse to provide the infrastructure needed by all Eclipse plugins.
There are lots of web resources on writing Eclipse RCPs, see here for example.
You cannot run Eclipse plugins in an ordinary Java program.
I installed Eclipse IDE for C/C++ Linux Developers to write some cpp codes. As I understood it, no matter which version of Eclipse I use, it always can be used to writing some java source codes.
I did this:
File->New>Java Project->...
Wrote a simple "hello world". I have confidence that my hello world is correct.
When I wrote my code, Everything went well.
But when I right clicked my new project, I found there was no "Run as","Debug as"
Press Ctrl+F11. It said "the selection cannot be launched, and there are no recent launches"
Run->Run Configurations. I double clicked Java Application. It said "No tab group defined for launch configuration type org.eclipse.jdt.launching.localJavaApplication"
What should I do?
How can I run my java applications?
Quite contrary to what you assume, eclipse isn't a Java IDE with some other addons. Eclipse is just a platform. As the package comparison shows, the C/C++ package doesn't come with the Java development tools.
Make sure you have correct eclipse version is downloaded? There will be separate eclipse version available for Eclipse for java.

Hope this help.
If you have the JDT installed, then make sure you are in the Java perspective. Either:
Window->Open Perspective->Java (default)
Use the perspective switching tab, usually the top-right of your code editor
You can install the JDT, if you don't have it by using:
Help->Install New Software...
Try to install follow this link http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/indigor if it's work. i think your eclipsec/c++ may be have a problems while install java. You can reinstall or using eclipse for java.
I am Java beginner. I have developed only two Java desktop applications and I use Eclipse as IDE. Right now I wanted to work on this project https://nbjfuguesupport.dev.java.net/
All code is in Netbeans. I suceeded to import all libraries that are used in source files in eclipse, and I have no errors showing in code in Eclipse. The problem is that I don't know how to run that code from eclipse. I don't know which class has main method.
Using google I found out that Netbeans uses org.netbeans.core.startup.Main.main to start projects, but I cant't find this in my libraries. Does anyone know in which .jar does this class come with netbeans 5.5 files. ??
Regards.
P.S. I must use Eclipse because I have a team of 3 men who have also only used Eclipse in the past, and we need this code to help us in similar project for college.
You can find the core.jar file that contains Main class under:
C:\Program Files\NetBeans 5.5\platform10\core\
You can simply include that in your Eclipse Java Build path.
I have a question regarding the development of liferay portlets using the liferay plugin SDK. My question goes mainly in the setup of the development IDE. The suggested one would be to use Netbeans IDE which I also tried out, but it appears to run very slowly on my machine while Eclipse is quite performant.
The setup for Netbeans IDE is the following
Go to the directory \portlets
Run the create.bat (or sh file depending on the OS) to create a new sample portlet
Run Netbeans IDE, create a new "Java free form project" and point it to the directory of the created sample portlet
That's it, pretty simple.
For the mentioned reasons above (and because I'm a lot more familiar with Eclipse) I'd like to import the project into Eclipse the same way. Is there a way for doing it without having to change too much in the original structure of the created sample portlet and the according build.xml (ant file)?? I tried already to create a new project out of the build.xml ant file of the created sample portlet, however in this way it doesn't include me the source code.
I didn't also find great tutorials on the web...
Could someone help me with this, pointing out online tutorials or give me some hints.
Thanks
I know your pain. Starting to work with Liferay needs much time. I you do not want to edit the existing source, but only crate your own portlets, you can download the plugins SDK from the 'Additional Files' section on the Liferay website. This provides ant scripts, to create a simple JSR compliant portlet, and to create all necessary things, to create a sound Eclipse project, for example:
ant -Dportlet.name=<project name> -Dportlet.display.name="<portlet title>" create
Than cd into the directory of your created portlet an do:
ant setup-eclipse
After that you should be able to create a new project from the sources in that directory in Eclipse, which can then be deployed via another ant script to the running tomcat instance. If you already know somthing about portlet programming, you shoud be pretty much settled now. If not, try to find documentation about JSR portlet programming first, before looking into Liferay specifig portlet development.
Liferay has now released an official set of Eclipse plugins that support portlet development. Here is the installation guide for installing the eclipse plugins:
Liferay IDE Installation Guide
Also there is a getting started guide that shows what to do after installation to actually setting up your first portlet project.
Getting Started Tutorial
Liferay IDE uses the Plugins SDK from Liferay under the covers to do all the work. If you already have existing projects that you created with the Plugins SDK those can be imported into Liferay IDE as well.
Importing existing Projects
you can find the tutorial for deploying liferay in eclipse
http://www.liferay.com/web/guest/community/wiki/-/wiki/Main/Development+Environment+(Windows)
No clue about Liferay's specifics, but in general, I'd do this:
Follow the steps 1 and 2 from your NB setup list
Create a new Dynamic web project (or a Java project if you don't need the web project's features) in Eclipse
Import the contents of sample portlet directory by doing Import -> File system in Eclipse
Adjust the project's Java source directory to point to the generated sample portlet source directory (that should now appear in your project)
Adjust classpath of the project, point it to LR lib folders, ...
If there's a generated build.xml, check if it can be used to deploy to LR, or to produce builds.
As of March 2011, there is some official Liferay support for NetBeans and as noted before, there is official support for Eclipse ( In the Marketplace). The Documentarian uses Eclipse himself, though many examples just use the Plugins-SDK with shell scripts, ant scripts and no IDE.
We are fighting with Liferay on Eclipse, Eclipse seems buggy and unpredictable, but we are also new to J2EE and Eclipse ( so discount this last comment a bit), and I have our portlet files setup in a separate area for SVN, requiring a refactor-move, refactor is definitely buggy.
You should be aware that there is a book for developers on the way from the official documentarian - we've bought the early release and found it useful. He does cover some IDE issues. See Manning press.
The Liferay sample portlets ( there are many) are not set up for Eclipse projects, and you'll have to import some java files and jump through some Eclipse hoops to get them into a running Eclipse project you can develop.
