When you create a Maven based web app project, you specify the spec version of the project as you create it.

<a href="http://www.freeimagehosting.net/uploads/20d7e476a5.png" rel="nofollow noreferrer">image of the Maven web App Wizard with default values http://www.freeimagehosting.net/uploads/20d7e476a5.png</a>

If you want to create a project that you can deploy with Tomcat, you need to change the value of the 'Java EE Version' field from 'Java EE 6' to 'Java EE 5', before you hit the Finish button.

Note: I had hoped that there was a simple change that could be applied to your projects pom file to convert it from Java EE 6 to Java EE 5... but it turns out that it is not so easy...

Is your webapp a real Java EE 6 webapp (without <code>web.xml</code> or with a Servlet 3.0 <code>web.xml</code>)? 

If yes, maybe NetBeans doesn't show Tomcat because Tomcat is not a valid runtime environment for your application (use GlassFish).

I had this exact same issue, when creating a default EE project in Netbeans it does a full EE spec which Tomcat doesn't fulfill.

I created manually because I couldn't find a good archetype, could you please post the place where you got the good Tomcat archetype?

blocks|key|1828683|text|我也遇到了同样的问题并解决了它；|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1828684|这是因为Java+EE版本比tomcat版本要求更高。|1828685|要做什么:|offset|length|style|BOLD|1828686|单击项目选项卡附近的文件选项卡。在nbproject文件夹下，选择j2ee.platform，如果您使用Tomcat7，则将平台更改为1.6+(例如，Tomcat6>+Jave+EE+1.5)。而不是在项目上进行“清理和构建”。|1828687|现在，服务器将位于Project+>+properties+>+Run+>+Servers|1828688|entityMap^0|0|0|0|5|0|A|5|H|9|X|D|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@$F|S|G|T|H|I]]|9|@]|A|$]]|$1|J|3|K|5|6|7|U|8|@$F|V|G|W|H|I]|$F|X|G|Y|H|I]|$F|Z|G|10|H|I]]|9|@]|A|$]]|$1|L|3|M|5|6|7|11|8|@]|9|@]|A|$]]|$1|N|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|O|$]]

I had the same problem and solved it ;
It was because the Java EE version was higher than the tomcat version requires.
What to do :
Click the files tab near projects tab. Under nbproject folder , select j2ee.platform , if you use Tomcat7 than change the platform to 1.6 for example(Tomcat6 &gt; Jave EE 1.5). than make a &quot;clean and build&quot; on the project .
Now the server will come at Project &gt; properties &gt; Run &gt; Servers

blocks|key|433817|text|当我遇到这个问题时，我犯的一个错误是我试图将EAR项目部署到Tomcat。Tomcat不是应用服务器。它是一台web服务器。当我将EAR的惟一Web项目部署到Tomcat时，它就可以工作了。ejb只能部署到应用程序服务器。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|433818|我希望这能帮到你。|433819|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

One of the mistakes I was making when I got this problem was that I was trying to deploy EAR project to Tomcat. Tomcat isn't an application server. It is a web server. It worked when I deployed the only the Web project of the EAR to Tomcat. The ejb can only be deployed to an application server. 
I hope this helps.

A more updated "web-app" should look like this.

I've added Tomcat in the "Tools > Servers" menu and as you can see it appears in the list of servers:

But when I try to run my project, I cannot select Tomcat! The drop-down with servers is empty. I tried it with NetBeans 6.8 and 6.9 Beta. Any idea?

The end: I've used the wrong archetype so that NetBeans decided that Tomcat is not capable to execute it.

我已经在"Tools > Servers“菜单中添加了Tomcat，正如您所看到的，它出现在服务器列表中：但是当我尝试运行我的项目时，我不能选择Tomcat！带有服务器的下拉列表为空。我在NetBeans 6.8和6.9测试版上尝试过。有什么想法吗？最后:我使用了错误的原型，所以NetBeans认为Tomcat不能执行它。
