I needed to create a java document, and I have inteliji ultimate, but when I create it, it does not appear, I found this link that says that it is necessary to add Java EE: EJB, JPA, Servlets plugin, but it still does not appear.
is what I am looking for
enter image description here
this way it appears to me
enter image description here
thanks :)
I tried the solution on this website, and it didn't work.
Java Enterprise doesn't appear in IntelliJ
I also tried to deactivate and reactivate the plugins
The Java EE is now called Jakarta EE.
See post, Java EE vs J2EE vs Jakarta EE.

I have IntellijIdea14.1.2 (Community version) on Ubuntu 12.04LTS
I am trying to create a web application project from scratch and I chose to follow this guide
https://www.jetbrains.com/idea/help/enabling-web-application-support.html#new
But I am not getting the option mentioned in Step 3 "Under Additional Libraries and Frameworks, select the Web Application check box.
Select the version of the Servlet specification to be supported from the Versions list. "
Only thing I see there is Groovy. Can someone tell me what to do to enable the other options in that list? I tried looking at the facets page and even that seems to assume that there are options available which I cannot see on my client.
Similarly I cannot see the rest plug-in mentioned in this page when I search for restful https://www.jetbrains.com/idea/help/preparing-for-rest-development.html
I tried reinstalling IntelliJ thinking something was wrong with the installation but doesn’t seem to be the case.
With the community version, you can only develop Java SE applications. For developing web or enterprise application, you need to buy the commercial version. Please refer this documentation to check difference between Editions

I'm planning to migrate the application from J2EE 1.4 to Java EE 7. The target platform is Eclipse Indigo, JBoss 7.1, Servlet specification 3.0/3.1.
Questions:
What are the issues arises ?
Is just changing the deployment descriptor (web.xml) ?
Does web services features exist in J2EE 1.4 ?
Should I create a new project and copy all the source code is better or there is better approach ?
Please enlighten this. Thanks.
There are many things changed since 1.4, for example, enterprise java beans has new annotations, depreciating some of the JSF old anotations, and many other changes, so, yes, it's a hard work to do, the best you could do is to start a new project and add all the functionality (will be easy, JSF 7 has many, many advantages), then when it's ready replace the old one in production, all the changes will depend on how many features you are using, i really recommend to do the migration, especially after Java EE 5 i love Java EE, but in general and very probably will break a lot of code (xml's, configurations, views and other many things)
What type of developer are each of these IDEs aimed at? Is one IDE a superset/subset of the other? What can I do using one and not the other?
I'm looking to do mostly desktop based (Windows) work for now so I believe I am correct in ignoring the Java EE download and focusing on these two.
The comparison of features page isn't helpful as I'm still new to Eclipse and Java. For example "Code Recommenders Developer Tools" means nothing to me yet.
Eclipse standard has been downloaded 1.7 million times and is 246MB (as at 7-Sep-13). While Eclipse IDE for Java developers has been downloaded 430,000 times and is 151MB.
So I'm guessing Eclipse Standard is the way to go, but why do they offer the second option?
All the other answers are more or less true, but miss the point (in my opinion), The download page states it clearly:
Eclipse Standard ...
The Eclipse Platform, and all the tools needed to develop and debug it
versus
Eclipse IDE for Java Developers ...
The essential tools for any Java developer, including a Java IDE, a CVS client, Git client, XML Editor, Mylyn, Maven integration...
So if your focus is to develop for Eclipse itself, the Eclipse Standard includes all what you need (including the sources of all features and plugins).
If your focus is Java development (not Eclipse plugins), you should start with the Eclipse IDE for Java Developers.
If your focus is Java EE development, it is simpler to start with Eclipse IDE for Java EE Developers and so forth ...
The comparison page could certainly use some links, nevertheless a quick web search will tell you all about those plugin.
For your needs, you might look into the "for Java Developers" package, as it contains WindowBuilder, which let's you define GUIs visually in several frameworks.
(Code Recommenders is also nice, but I've personally found it a bit hit-or-miss)
However, you're fine installing any of the packages either way, since you can always install the plugins you need later on. My recommendation is to simply read about those plugins and make an informed decision on what you should install.
If you're doing GUI work then you might choose the Java Developers package as it comes with WindowBuilder.

Best GUI designer for eclipse?

The difference between the eclipse downloads are just the pre-installed plug-ins.
I'd go with standard and install the plug-ims i want, but take what fits you.
I am learning EJB and to do that I bought a book name EJB 3 Developer Guides. I got some understanding on how EJB architecture is and how it works. The book does well in explaining this.
But the examples in the book are all run through ant task. I basically wanted to learn how EJB's are being used in conjunction with Servlets and JSP. Some sort of a web client accessing a JSP page and a servlet getting the service of an EJB bean?
Any idea how can I move forward learning how to use EJB with the Web Tier? Tutorials or links would be better or is there any other book that I could read?
Thanks.
Simple EJB3 Servlet Application
And another option is Netbeans Java EE and Java Web Tutorials -- a best bet, if you are using Netbeans. And if you are not, and you are new to Java, I would highly recommend you Netbeans IDE. It is simple and straight forward.
Important note: if you try running the "Simple EJB3 Servlet Application" from the link about be sure you are using an appropriate version of Glassfish. It might work on JBoss 5.x - but I've never tested it (according to JBoss).
You won't be able to run on the sample application on older versions of JBoss (like 4.2.x) without some workarounds - like ones I described in one of my posts: sample application
The Netbeans tutorial seems fine - but stick to the environment and platform they are describing - otherwise you might quickly discourage and give up.

I am on a Java learning spree recently, however I am normally a .NET developer. (So please forgive my newbie questions.)
In .Net I can develop ASP.Net pages without using IIS, as it has a watered down web server (Cassini, I think it's called).
Does Java or a Java IDE have something similar so I can write and test JSP and Java Servlets without the need of a full-blown app server (Tomcat etc.)?
Also if there is one, does it work on Windows?
Tomcat actually isn't a fullblown appserver. It's just a servlet container (i.e. implementing only web component of the (indeed huge) Java EE API) It's only around 6MB big. Glassfish, JBossAS, Weblogic and Websphere as being full Java EE API implementations may be called as "fullblown appservers".
You can also consider Eclipse Jetty. It has a small footprint (download is only 2.2MB) and is useable as an embedded server and even runnable from a plain vanilla Java class.
As to IDE's, both Tomcat and Jetty are by default supported in "Eclipse for Java EE developers". You can easily integrate them in Servers view and then just associate your web project with it. Here's a nice video tutorial how to get started with servlet development with Eclipse and Tomcat.
As to working on Windows, Java is platform independent. You just need to have a platform-compatible JRE installed. Then any Java software will be able to run on the particular platform. Sun has a JRE for Windows --which is by the way also included in the JDK, if you already have one.
In the Java world the usual way to develop JSP based applications is to have a web container like Tomcat inside the IDE, and there are many ways to do it.
The easiest way to get started is to use Netbeans with a bundled web container - download the "Java" one from http://netbeans.org/downloads/index.html and install it.
After starting Netbeans 6.8, "File -> New project", choose "Java Web" to the left, and "Web application" to the right, and "Next". "Next". "Next". "Finish".
The editor now opens on "index.jsp" in a new project. Select "Debug -> Debug Main Project" and after a while a browser opens showing "index.jsp".
Switch back to Netbeans. Insert this line
<%= new java.util.Date() %>
just before the </body> end tag, and save with Ctrl-S (or "File -> Save").
Switch back to the browser. Reload the page. See the date shown. Repeat :)
That's it.
You can hook up your ant scripts to hot deploy to a local tomcat instance. That's the closest thing I can think of to the .NET development environment.
Eclipse can embed a dev version of Tomcat, and most other IDEs offer a dev server too, I should think.
But also I should also point out that obtaining & setting up Tomcat is quite a bit simpler than setting up IIS. Just download a zip file and unzip -- poof! you're done!
When I was playing with JSP a while back I used NetBeans which has a Web & Java EE-installer, that
Provides tools for developing Java SE,
Java EE, and web applications. This
download option also includes the
GlassFish V2 UR2 application server
and Apache Tomcat software.
Try Jetty http://jetty.codehaus.org/jetty/
Jetty is an Open Source HTTP Servlet Server written in 100% Java. It is designed to be light weight, high performance, embeddable, extensible and flexible, thus making it an ideal platform for serving dynamic HTTP requests from any Java application.
