I'm following this tutorial about using Google engine API to create web application.
When I add any file with .jsp suffix into my war folder the project will not compile any more.
What can be the reason ? If you need more information please just leave some comment. Thank you.
Can it be that I it cannot compile because I did not download "Eclipse for Java EE developers" but only "Eclipse for Java developers" ?
I'm not sure. I see <Java EE> in the title bar in your Eclipse screenshot which is typical for Eclipse for Java EE developers. So you have likely the right version. If you are able to do File > New > Dynamic Web Project then you definitely have the Java EE version or at least the one with WTP. More detail can be found in Help > About Eclipse.
the error in Markers tab is "Your project must be configured to use a JDK in order to use JSPs"
You need to install the JDK. Go to the Java SE download home page and click the leftmost one of the four big buttons. Done that, go in Eclipse to Windows > Preferences > Java > Installed JREs, select the existing JRE, click Edit and let the JRE home path point to the JDK folder.
It it asking you if you want to run even though it found errors in the project. First, what are the errors and can you fix them easily? Eclipse gives pretty good error messages. If the errors are from validation, turn them off in the project settings, then try running the project again.
Otherwise, double check that you are using the exact code from the tutorial. Copy the code from Google and save it into a separate file. Then select your file, and the new file, right-click on the two files and use Eclipe's file-compare to show you if you missed anything.
[edit]
You could install the EE version to a different directory. Different versions of Eclipse do play nice with each other, they're just huge. Do not import your project into the EE workspace. It will come across as a plain Java project and you need a Web project. Create a new Web/JSP project and then copy the files over.

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.
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
http://oss.opensagres.fr/angularjs-eclipse/0.6.0/
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.
Hi Guys if u are using angular plugin in eclipse that time is plugin is limited periods after that if u want to used this plugin then u pay it so i suggest to you used webstrome and visual code ide that are very easy and comfort to used so take care if u start and developed a angular app using eclipse
I am currently developing an application with my software engineering classmates. I am experiencing a few issues with Eclipse, however. But first, some information about my Eclipse: I am running version: Juno Service Release 2 with a build id of 20130225-0426. I am running Eclipse on my MacBook with OS X Mountain Lion 10.7.5. I am using SVN to upload and download the project to a repository through assembla.com.
First, Eclipse will not recognize any errors. If I purposely type random characters, Eclipse does not underline them with red.
Next, whenever I type "this.whatever" or "# for javadoc" I receive the following message: "this compilation unit is not on the build path of a Java project." I can click "OK" and continue with no problem though.
Finally, whenever I attempt to run the program I receive this message:"The selection cannot be launched, and there are no recent launches."
Other notes: I do not have any of these issues with any of my other projects in my workspace. I also have another project using the assembla repository that does not contain these issues. These issues just occurred all of the sudden.
Edit: None of the other members in my group are experiencing these issues. I have attempted to download the project from the repository on a different machine and I still have these problems. I have attempted to delete the project from my workspace and re-download. Still a no go.
Update: I even installed the Android Development Kit and used the included copy of Eclipse. It will still not work properly.
What is going on with my Eclipse?
Since I guess you're in start phase of android coding and you're not addicted to a special IDE, I strongly recommend the IntelliJ IDEA instead of Eclipse for Android development. I have tried Eclipse already and because of its weaknesses, now I'm using IntelliJ. Eclipse is not the best IDE for Android development and have a long way to become the one.
IntelliJ IDEA
I suggest you try installing the ADT bundle in a new location and see if you still have these problems. The ADT bundle includes the latest Android SDK along with a version of Eclipse with the ADT (the Android Developer Tools plugin) already installed and configured. It's possible that you have (or have had in the past) other Eclipse plugins that affect how the Java tools in Eclipse work, possibly in a way that interferes with ADT. I have personally had problems like this in the past with tools like Aptana, where even after uninstalling there would be problems.
Eclipse is telling you already with the above error message: You don't have your sources on a build path, but just in some folder.
Either you have created a simple project instead of a Java project, which then also doesn't do anything Java specific. Or you have created your Java files in plain folders, instead of source folders.
The best way to sort this out is to create a new Java project using the Eclipse "New..." wizard from the main menu. Compare the result of that to your project. The two important things are: The project has an icon with a small "J" overlayed. The Java sources are shown in packages, which themself are in source folders (with a package overlay), not in simple folders.
I reinstall my Eclipse environment every year when the new version is released. The most recent release - Juno - however, does not work as expected.
Currently, when I try running demos from Oracle, for example, it asks me to select an Ant file to run before compiling. After creating a blank Ant file to bypass the requirement (which I thought was rather dumb, since I don't think TDD is something that should be forced on people), it still refused to run, saying the "Selection could not be launched."
I understand that Juno is an update from the 3.x track to the 4.x track, but this seems a little ridiculous to me. What can or should I do so I can get Eclipse back up and running again?
Just to clarify:
All files in question are on my Eclipse workspace path
I don't do much in the way of Java development, though I know I'll need to do so soon. Hence, my unfamiliarity with the most recent version of Eclipse.
I would like to run my files & projects without Ant files. I know it has something to do with Run configs, but I don't know how to change them.
Here's what I did to run the demo from Eclipse Juno:
Downloaded the project from http://docs.oracle.com/javase/tutorial/uiswing/examples/zipfiles/components-FrameDemoProject.zip (if this is not the correct demo, then please provide the link you're using)
Unzipped it to my projects directory (not my workspace), so that you have:
PROJECTS_DIR/components-FrameDemoProject/src
PROJECTS_DIR/components-FrameDemoProject/nbproject
PROJECTS_DIR/components-FrameDemoProject/build.xml
From Eclipse, File > New > Java Project
List item Uncheck Use default location and navigate to <PROJECTS_DIR>/components-FrameDemoProject
Hit Finish
Drill down to src/components/FrameDemo.java
Right-click on FrameDemo.java and select Run As > Java Application
Let me know if any of these steps give you trouble.
Take a look at you project properties and select the Builders entry. Do you see an Ant Builder entry? Try to select or create a Java Builder entry instead.
I just created a new Java Project in Juno and added the FrameDemo.java source. In my case, the Java Builder was selected as the default for this new project.
I'm a Java noob (but have been programming for 25+ years, and have worked with OO languages from day 1).
All of a sudden I started getting this error:
Your active platform is: JDK_1.6, but the corresponding property "platforms.JDK_1.6.home" is not found in the project's properties files.
Not sure what caused this condition, and not sure what Java's asking me to do. I'm working in the NetBeans IDE. The last thing I attempted to do is add some binary (image) resources to my project.
In my case the JDK setup in Netbeans was fine. It was just one of those strange Netbeans issues that come out of nowhere.
My fix was:
Clear the Netbeans Cache i.e. delete the folder:
C:\Users\\AppData\Local\NetBeans\Cache\
It means you haven't told netbeans where your Java 1.6 installation is. Go into settings, add the JDK (JDK->Add->New), and select the directory above 'bin' for your JDK16.
This error can occur at two scenarios:
Right click your netbean project -> Properties -> Libraries
After select Libraries , right panel on top you can see "Java Platform" combo box. This Jave Platform is missing for your project. You need to add using Manage Platforms bottom beside Jave Platform combo box.
Even thought scenario (1) is correct it can happen. Because your project has reference to another netbean project in your Libraries. This reference project is missing Jave Platform.
I have Linux in my office and Mac in Home and this problem is frequently when I share projects in github, I solve it removing the build directory and doing clean and build.
Right click on project - Properties - Libraries - Select the correct jdk version from the Java Platform combobox.
NetBeans bug
If your project depends on other projects, open and clean build all of them(that fixed it for me).
Most likely cache-related stuff. Clean up NB cache as suggested by someone before
You should remove the files under private folder in the nbproperties folders.
for me any recommended way early didn't helped, but changing in project Properties -> Source/Binary format to JDK 7, Save than change back to JDK 8 fixed this error
