Install Java EE Developer Tool on Eclipse Luna in a virtual machine

I am trying to install JAVA EE Developer Tool(for Dynamic web project) in Eclipse Luna onto my Virtual Machine but unable to see the selection options. Here is the image showing what i am struggling with:

If you want to solve the problem in an easy way then you should simply download Eclipse IDE for Java EE developer. You can do that from the links below.
http://www.eclipse.org/downloads/eclipse-packages/
If you want to get it from Eclipse Marketplace then you will have to search for webtools platform. Refer to the link below for more information.
https://eclipse.org/webtools/
http://download.eclipse.org/webtools/updates/
To install it, just add the following URL
http://download.eclipse.org/webtools/repository/luna/
If you want to get Eclipse oxygen repository, then you would add the same above url but replace the version name like.
http://download.eclipse.org/webtools/repository/oxygen/

How to attach source code of Java EE in Eclipse? [duplicate]

Where can I find JavaEE packages' sources?
I downloaded the Java EE 6 with Glassfish server from Oracle's website. Then I created a Java EE project in Eclipse. But I wasn't able to find the source code attachment when I click "Open Declaration" on a Java EE class in Eclipse.
It says "Source not found" for Java EE classes in the class file viewer. I can, however, find the source code for Java SE classes from the installed JDK directory in glassfish3/jdk/src.zip. But for Java EE API, I couldn't find the source code zip file from the downloaded Glassfish JDK directory. Any suggestions?

The source code for glassfish is on the main glassfish download page for example http://download.java.net/glassfish/3.1.2.2/release/glassfish-3.1.2.2.zip
Once you navigate to a class and eclipse tells you it does not have source you can click on the locate source button and navigate it to the zip file.
Update my mistake the above link was the binaries, it looks like the source has to be obtained directly via checkout from subversion you can find the correct branch to checkout here http://java.net/projects/glassfish/sources/svn/show/tags you need to look at your startup log or use asadmin version to figure the build number so you can chekout the correct source tree. once you have checked out the correct source tree then you can point eclipse at it.
see this blog for more details http://amitstechblog.wordpress.com/2011/04/29/glassfish-source-code/

Building example code using asant

I'm studying java web services and trying to follow the oracle tutorial but it tells me to build and deploy the example code using asant. I've looked high and low and I can't find it. It doesn't seem to be included with Glassfish any more. I'm using Glassfish version 3, JDK 1.6.
Can anybody tell me where it is or how to get it?
Thanks in advance.

asant shipped with the GlassFish 2 releases. It was a wrapper that included a number of convenience tasks.
As the team that Sun used to develop GlassFish shrank, some 'features' of the releases were pruned from the GlassFish 3 development work. Asant was one of those features.
Your best bet may be to follow the Web Services section of the Java EE 6 Tutorial. It will be more up-to-date with the current state of the art.

asant is a command line using apache ant, it helps you to build your project using ant, you have to write a build.xml file, and then run the command asant

Yes I know what it is and what it is supposed to do but I can't find it in my distribution
of glassfish, where it is supposed to be. – ac7web
if you have it installed it should be in: glassfish-Install-Folder/bin

Enabling full documentation for Java EE in eclipse

I'm new to Eclipse and am using it currently to play with Java EE.
When using Ctrl+Space for types/functions from the regular Java libraries I get a full description (i.e. general description of the type, what are the arguments of the method for, etc.). However I don't get the same for Java EE types.
For example, when using Ctrl+Space on methods of the HttpSession class I get only names like "arg0" or "obj" and no description.
How can I remedy this?

I'd suggest downloading the javadocs and adding them in eclipse. (right click project > properties > java build path > libraries > expand the library > set Javadoc location)

I think that's why Java EE defines a specification only, the implementation must then be done by the provider of your application server. javax.servlet.http.HttpSession e.g. is bundled in servlet.jar.
It you are using Tomcat as your application server, you could attach the java sources to your servlet.jar and then you can browse the source and read it's javadoc.
The source for the latest tomcat is here ->
http://www.apache.org/dist/tomcat/tomcat-6/v6.0.26/src/apache-tomcat-6.0.26-src.zip

I wanted to add what might be very pertinent information for projects using maven and eclipse / wtp. What I did to get the Javadocs to attach nicely was the following 2 steps.
1) I am using glassfish so using the glassfish plugin site I installed the java ee 6 (or 7) documentation. You can easily view this documentation with Help->Java EE 6 docs. I copied the URL from here.
2) Opened my projects build path and went to the libraries tab. Opened the Maven Dependencies and found the java ee 6 api entry (this should be part of the maven project). Opened this up and was able to add a location for the javadocs for the api. I pasted the file:/// url I had copied.
Then I verified this worked by using the ctrl + shift plus mouse pointer hover over some of the java ee 6 classes and methods.
I hope this information will be useful to other who searched and got here but didn't find the solution they were looking for (or for those who now use Maven!).

Building a Java EE app on Mac OS X Snow Leopard for Glassfish 3

I'm having a bit of a problem building a Java Enterprise Edition web application on Mac OS X 10.6.2 using Ant 1.7.1, Glassfish v3 and Java EE 6.
The problem is that the build process does not find the Java EE libraries which fair enough as I don't think Apple supply them with the default Java installation but I know they exist in the Glassfish distribution.
Which jars are the correct ones to build against (I'm assuming javaee.jar is a general jar which references all the other needed jars) and what should I be putting in my ant build.xml file?
Any help is very much appreciated.

You need to have the javaee.jar in your ant classpath, but be aware: do not copy the javaee.jar to the webapp (WEB-INF/lib folder)!

I would encourage you to get and use NetBeans or GlassFish Tools Bundle For Eclipse to start working with Java EE 6 and GlassFish v3... (read my profile to find out why).
If you are determined to avoid using either of these IDEs, then I would recommend that you download the Java EE 6 SDK, to get started. The SDK includes a number of different samples that can be built and deployed using Ant. (Use -verbose to learn the 'secrets')
