Cannot create Dynamic Web Project on Eclipse, project facet already installed

So I am new to working with web and server related projects and I am trying to create a new Dynamic Web Project on the Eclipse IDE.
After clicking finish on the "new dynamic web project" window, a new project is created (though it is missing most folders) and the window remains open. If I hit Finish again, I am prompted with this error: "Cannot install project facet Java 10. Some version of this project is already installed."
If I simply close the window, after the project is created, it lacks files I am seeing in examples online, and I cannot create a new servlet for it.
The following query: "Cannot install project facet" error while creating a project?
Is not really helpful as it relates to creating a project from existing code and that seemed to be the source of the issue.
I already tried using different project names, and web module version but no luck.
Any help would be appreciated

As mentioned in the comments the problem was indeed with the version.
Updating to the latest version of Eclipse IDE for Enterprise Java and Web Developers fixed the issue.

How to add the JSF 2.0 plugin to eclipse?

I want to make a "Hello World" app on eclipse using jsf config. I couldn't find the link to install the plugin!

Go to the eclipse in "Help" -> Install New Software-> Add the following addres to the update site of jboss tools "http://download.jboss.org/jbosstools/updates/stable/kepler".
In this case I'm using the eclipse Kepler the newest version of eclipse, you have to verify which eclipse version you have before download.
Select the Option "Jboss Web and Java EE Development" when you see the available software for update.

Download the Java Enterprise Edition Package for eclipse instead.
It has the jsf stuff included already.

axis2 support in netbeans

I am using netbeans 7.0 and want to generate axis 2 web service from my java code.
I googled and it and found that they removed support for axis to in 7.0 v.
Then i came across this link
http://netbeans-org.1045718.n5.nabble.com/Axis2-Support-in-Netbeans-7-0-td4383308.html
Someone there mentioned to use plugin the Dynamic "Development UC" update center.
Now i have the updates.xml file.What should i do with it to install the plugin?

In Netbeans, go to Tools/Plugins/Settings
ADD, enter a name, then pass in the url you've got.
That will load another bunch of plugins for Netbeans, then in the 'Available plugins', you should now have the 'Axis2 Support' plugin there ready to install.
When I installed it like this it wasn't enough, I also had to right click on it from the installed plugin list, and then click Activate.

What can't I see the run-as server option in eclipse

I'm working on a project in Eclipse Version: 3.5.2
My colleague and I both checked out the same maven project from svn. I'm trying to debug it by running it in Tomcat.
He can see the run-as server option when he right-clicks the project, but I can't.
What did I forget to do?
I can't even see the server option under Window->Show View->Other
Thanks

Deployment of applications on Java EE Application Servers or containers is possible only when you have WTP installed. From the screenshots posted, I can infer that either WTP is unavailable or it hasn't been loaded by Eclipse (for some unfortunate reason).
You ought to perform one of the following:
You can get a copy of the Eclipse IDE for Java EE developers, which contains WTP by default. If you need the Galileo edition, you will need to look into the Galileo archives. Also, you should use a JDK to start Eclipse. WTP might not be available if you use a JRE.
If you do not wish to install Eclipse with WTP from scratch, install the WTP plug-ins. Use the Galileo update site for this.
If you are sure that you have WTP installed, but you are unable to find that Galileo has loaded the plug-ins, then you will need to inspect the contents of the .metadata\.log file in your workspace. This would give you a hint as to why the plug-in was not loaded. Start Eclipse with the -clean flag, to get Eclipse to detect the plug-in if it hasn't done so previously.
Note: If WTP has been installed, you should be able to confirm this by view the list of loaded features, as shown below.

Here's are some instructions I wrote up when I configured my Eclipse to work with Tomcat. Hopefully it'll help you.
Open Servers Window
Open the Servers view.
If servers view is not open, select menu item Window/Show View/Other...
Select Servers under the Server section.
Add New Server
Right Click in the Servers View select New/Server
Expand Apache and select Tomcat v5.5 Server
Click Next.
Select the directory of your Tomcat installation. (ie c:\tomcat)
Click Finish

This will be the solution for all your questions. A must read pdf.

Did you create a Web Project? If you right click on the project and go to Properties > Project Facets is Dynamic Web Module selected. This works for me.

In case of web application 3.0 in my case i have taken war file of project and deleted existing app from eclipse and replaced it with war it worked for me

Importing Liferay portlet into Eclipse IDE

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.
