I have created a Dynamic web project, but I am not able to deploy it into Apache Tomcat Server 6.0. I am getting this error when I try to deploy my project:
There are No resources that can be added or removed from the server.

For this you need to update your Project Facets setting.
Project (right click) -> Properties -> Project Facets from left navigation.
If it is not open...click on the link, Check the Dynamic Web Module Check Box and select the respective version (Probably 2.4). Click on Apply Button and then Click on OK.
回答2:
Check whether your Java version is compatible with the project. Right click the project>>Properties>>Project Facets>>Java check the version is compatible with your project.
回答3:
if your project maven based, you can also try updating your project maven config by selecting project. Right click project> Maven>Update Project option. it will update your project config.

The issue is incompatible web application version with the targeted server. So project facets needs to be changed. In most of the cases the "Dynamic Web Module" property. This should be the value of the servlet-api version supported by the server.
In my case,
I tried changing the web_app value in web.xml. It did not worked.
I tried changing the project facet by right clicking on project properties(as mentioned above), did not work.
What worked is: Changing "version" value as in jst.web to right version from
org.eclipse.wst.common.project.facet.core.xml file. This file is present in the .setting folder under your project root directory.

I used mvn eclipse:eclipse -Dwtpversion=2.0 in command line in the folder where I had my pom.xml. Then I refreshed the project in eclipse IDE. After that I was able to add my project.

I didn't find the Dynamic Web Module option when I clicked on the link, then I have installed Maven(Java EE) Integration for Eclipse WTP from the Eclipse Marketplace.Then, the above steps worked.
回答7:
I encountered this error even though the Project Facets were set appropriately. The problem was that the "Runtime Environment" property was not set on the server:
It simply needed to be set to the appropriate Runtime:
回答8:
The only thing that worked for me was creating a
.java-version
file with "oracle64-1.8.0.112" as the only entry ( use something that is 1.6+ )
Make sure you have dynamic web module facet turned on.

Right click on the project, select properties and then select "Targeted Runtimes". Check if Tomcat is selected here.
