In netbeans project category java folder is missing

i installed the netbeans IDE and java SEDK today. and the problem is i cant see the java folder in the project category when i tried to create a new project.

It looks like Java SE is not active in your Netbeans installation. To properly use Java SE features you have to follow these steps:
Choose Tools > Plugins from the main IDE's toolbar.
In the Plugins dialog box, click the Installed tab and select Java SE in the list of available features.
Click Activate.
At the Welcome panel of the Installer dialog box, click Activate. When the activation is successfully completed, click Finish.
Click Close to close the Plugins dialog box.

1.First go for Tools -> Plugins.
2.Then search for Java SE in available plugins and download Java
3.Go in installed plugins.
4.Activate plugin and that's all.

The #acm's answer is right. but you need attention that you are adding a new file at beginning of the Netbeans.
To resolve this problem, after you activated java SE as #acm's answer, you need to create a new project not new file on NetBeans.

In latest versions of NetBeans(12.6). You can create a console application from the following steps.
New Project > Java With Ant > Java Application

Can't create java application project in netbeans8.1.(ubuntu)

I am new to NetBeans and I can't create a "Java Application" project, like shown in all tutorials. I can only create a Java Free-Form Project, but this requires a build script, which I don't have either.
Do I have to download a plugin for it and if so which plugin? Or did I download the wrong NetBeans version?
I am using ubuntu version 15 and NetBeans IDE 8.1.

Just make sure you have JDK installed on your system. (I am pretty sure, it would be as Netbeans doesn't install if JDK is not found on your machine, but just to be sure about it). Also, You might have missed to select Java in Select Languages during installation.
To activate a feature manually:
Open the Tools > Plugins menu
Go to the Installed tab.
Select and activate the feature you need.
Return to the New Project dialog.

Found the plugin:
It was in the the "Ant" or the "Ant 1.9.4. Documentation 1.9.4" or Mobility plugin. I downloaded those 3 at the same time, but If I have to guess it was the Mobility plugin.

Not sure if this will help you. I've been working on Windows. I have Netbeans 8.1 and JDK 8 (version 1.8.0.73). When I first started with Netbeans and tried to create my first new Project it opened the New Project window with the Categories portion of the new Project screen focused on the Samples section. I also thought I couldn't create the type of project I wanted to create. If this is what is happening to you, see if you can scroll up in the Categories box. If you can, you should find Java at the top. If you click that, you should then be able to select Java Application in the Projects part of the window.

RCP or SWT to build eclipse plugin

I am new to eclipse plugin development. I want to develop a plugin which will generate XML files from the classes present in the workspace. It will have 2-3 UI forms which will take information from user while generating XMLs.
From what I have read till now, I think there are two ways by which we can develop plugins
SWT
RPC
I want to know which will be appropriate way to go for me ?

Both, they aren't mutually exclusive. SWT is the widget toolkit used in Eclipse, and RCP ("Rich Client Platform") is an application platform based on SWT that is also the foundation of the Eclipse IDE.
I'd suggest that you start with a project template. Get the latest "Eclipse for RCP and RAP developers" package from the Eclipse download site. Create a new plug-in project (File > New > Plug-in Project), check "This plug-in will make contributions to the UI" on the second page of the wizard, and on the last page, select one of the templates.
You should also have a look at the answers to How to write a plugin for Eclipse? to get started.
Please note that, while this approach still works with Eclipse 4, there are newer APIs to use if you target Eclipse 4 IDEs only. For documentation of this approach, see Eclipse 4 RCP (aka E4) documentation.

Configuring angularjs with eclipse IDE

I want to start using AngularJs and Java Spring for development purpose.I am using Eclipse as IDE . I want to configure my Eclipse to have these frameworks working seamlessly.
I know I may be asking too much,but trust me I have done much research on my part and you guys are my last resort.Any help would be much appreciated.

You'd first wanna make sure you have the JSDT installed.
Next thing is to install some dedicated tools for the job, so check out AngularJS Eclipse Tools. The AngularJS Eclipse Templates might be of help, too, and here's a visual guide written for it to get you started.
Also see the AngularJS Eclipse getting started page.
Since this answer had been posted, the AngularJS Eclipse plugin was released, as other answers stated. You might wanna check it out first.

Install JavaScript Development Tools (JSDT) and AngularJS Eclipse plug-in in eclipse from Eclipse Marketplace or Update site angularjs-eclipse-0.5.0,
Right Click on your project --> Configure --> Convert to Angularjs Project (as shown below)
Now you can see the Angularjs tags available as shown below.
.

Make sure the project is extracted on your hard disk.
In Eclipse go to the menu: File->New->Project.
Select "General->Project" and click on the next button.
Enter the project name in the "Project name:" field
Disable "Use default location" Click on the "Browse ..." button and select the folder that contains the project (the one from step 1)
Click on the "Finish" button
Right-click with the mouse on you're new project and click "Configure->Convert to AngularJS Project.."
Enable you're project goodies and click on the "OK" button.

Netbeans 8.0 (beta at the time of this post) has Angular support as well as HTML5 support.
Check out this Oracle article: https://blogs.oracle.com/geertjan/entry/integrated_angularjs_development

Since these previous answers above, there is now a release of an Eclipse Plugin to assist with development using AngularJS:
https://marketplace.eclipse.org/content/angularjs-eclipse
https://github.com/angelozerr/angularjs-eclipse/wiki/Installation---Update-Site (take a look around the other Wiki pages for information on features)
The release at the time of the answer is 0.1.0.
Please also checkout JSDT (http://www.eclipse.org/webtools/jsdt/) and also Eclipse VJET (http://eclipse.org/vjet/). The VJET project appears to be an attempt to provide better feature sets to the editor without being encumbered by the JSDT project (open source politics at play I guess).

Download angular js from this link and add as new software in eclipse

Configuration worked with Eclipse Mars 4.5 version.
1) Install Eclipse Mars 4.5 from
https://eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/mars2
This comes with Tern and embedded Node.js server
2) Install AngularJS Eclipse plugin from Eclipse Marketplace
3) Configure node.js server to the embedded nodejs server within Eclipse (found in the eclipse plugins folder) at Windows-> Preferences -> JavaScript -> Tern -> Server -> node.js. No extra configurations are required.
4) Test configuration in a html or javascript file.

With current Angular 4 and 5 versions, there is an IDE for that.
Go to eclipse market place any search for 'Angular'. You will see the IDE and install it.
After that restart eclipse and follow the welcome messages to choose preferences.
How to start using eclipse with angular projects?
Considering you already have angular project and you want to import it into eclipse.
go to file > import > choose Angular Project
and It would be better to have your projects in a separate working set so that you will not confuse it with other kind of (like java)projects.
With Angular IDE You will have a terminal window too.
To open this type terminal in eclipse search box(quick access) on the top right corner.

Where can I find the old "Developer Collaboration" plugin?

Once upon a time there is netbeans plugin called "Developer Collaboration" which allows you make remote pair programming.
Now, in Netbeans 6.7, there is no more this "Developer Collaboration" but there something called "Kenai support". Unfortunately Kenai does not seems to have a real time editor and it seems to be usable only for opensource project, but my project is closed source.
I switched back to the Netbeans 6.5 but I discovered that the "Developer Collaboration" plugin is no more available for download through the Plugin Manager (from Tools > Plugins) and I'm not able to find it from the plugin portal
Where can I find the old "Developer Collaboration" plugin? Or which alternative I have?

The user msmart posted this on the NetBeans Forums, explaining how to install the Developer Collaboration plugin on NetBeans 6.7:
For those of you who want to connect to an XMPP server for collaboration but cannot (or do not want to) use Kennai. The old Developer Collaboration plugin still works for 6.7 but you have to download and install the NBM files manually.
Here is how I got it to work:
1. Download the following NBM files from the Netbeans 6.5.1 repository.
com-sun-collablet-moxc.nbm
com-sun-collablet.nbm
org-netbeans-libs-xmlbeans.nbm
org-netbeans-modules-collab-channel-chat-html.nbm
org-netbeans-modules-collab-channel-chat-java.nbm
org-netbeans-modules-collab-channel-chat-text.nbm
org-netbeans-modules-collab-channel-chat-xml.nbm
org-netbeans-modules-collab-channel-chat.nbm
org-netbeans-modules-collab-channel-filesharing.nbm
org-netbeans-modules-collab-channel-output.nbm
org-netbeans-modules-collab-kit.nbm
org-netbeans-modules-collab-provider-im.nbm
org-netbeans-modules-collab-ui.nbm
They are currently located at the
following URL:
http://updates.netbeans.org/netbeans/updates/6.5.1/uc/final/stable/patch4/extra/
Put all these files in the same directory.
Open Netbeans 6.7.
Click Tools->Plugins
Select the "Downloaded" Tab
Click the "Add Plugins" button
Browse to the folder you saved the NBM files in.
Select all 13 files (CTRL A).
Click OK.
Click Install.
Enjoy.
