Cannot add a project to a tomcat server in eclipse

问题

I cannot add my project to a server in eclipse - why is that?

I installed all necessary tools (Web Dev, Java EE, Server Adapters, Tomcat itself, everything)

I configured the runtime environments, adjusted all Java Versions to JDK 6 (because it should run on Tomcat 6) but still the left side of the dialogue where I could add recources is empty when creating a new server.

What else could I try?

PS: Using Juno on W7 Prof.

回答1:

You didn't create your project as "Dynamic Web Project", so Eclipse doesn't recognize it like web project. Create new "Dynamic Web Project" or go to Properties -> Projects Facets and check Dynamic Web Module

回答2:

1 .right click on project name in Package Explorer view.
2. select Properties
3. Select Project Facets
4. Click on Runtimes tab
5. check server
6. Click on OK

And now :

right click on server name in Servers view
click on Add and Remove ...
move resources to the right column

I fixed this issue as adding Dynamic Web Module to Project Facets

right click on project name in Package Explorer view.
select Properties
Select Project Facets
Activate Dynamic Web Module
Click on OK

回答4:

If you are able to see the project in Eclipse project explorer but unable to see the project while adding the project to the web server, follow project properties -> Project Facets, make sure Dynamic Web Module & Java were ticked.

回答5:

Go to project properties -> Project Facets, make sure Dynamic Web Module & Java were checked.

Apart from it, "Cloud Foundry Standalone Application" needs to be un-checked, if it is already selected. By default, few IDE's pre-select this option.

Right-click on project
Go to properties => project factes
Click on runtime tab
Check the box of the server
Then ok

Close the eclipse and start the the server you will able to see and run the project.

回答7:

After following the above steps suggested by the other posters, do the following step

Right click on the project
Click Maven, then Update Project
Tick the check-box "Force Update of Snapshots/Releases", then click OK

you should be good to go now.

Steps, I used to resolve:

Double click on Tomcat Server in the Servers tab.
In a dropdown next to Runtime Environment:, select Apache Tomcat your version
Click on save.

Now, you should be able to add to server on right click "Add and Remove"

Note: Additionally, when on clear/run, you get an error for multiple instances, open server.xml and ensure that it contains a single instance of each application and not multiple.

In my case:

project properties -> Project Facets, make sure "Dynamic Web Module" is checked and, finally, I put the version number "2.3" instead of "3.0". After that, the Apache Tomcat 5.5 runtime is listed in "Runtimes" tab.
