Eclipse 4.2 (Juno) 'Cannot create a server using the selected type' in Tomcat 7

This is a known issue that can happens, to resolve this error, try one or all of the following:

Go to

Window–>Preferences–>Server–>Runtime Environments

and fix the broken path/link for the server.

Or rename the

org.eclipse.jst.server.tomcat.core.prefs to org.eclipse.jst.server.tomcat.core.prefs.bak

(or you can delete this file). This file can be found at \workspace\.metadata\.plugins\org.eclipse.core.runtime\.settings

Rename the

org.eclipse.wst.server.core.prefs to org.eclipse.wst.server.core.prefs.bak (or delete the file).

This file also can be found at the same location as above.

1 . To fix the error 'Cannot create a server using the selected type' run the following:

cd ~/workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/    
rm org.eclipse.jst.server.tomcat.core.prefs    
rm org.eclipse.wst.server.core.prefs

2 . Once you do this, another error

'Could not load the Tomcat server configuration at /usr/share/tomcat7/conf. The configuration may be corrupt or incomplete /usr/share/tomcat7/conf/catalina.policy (No such file or directory)'

So to fix this run the following commands:

cd /usr/share/tomcat7
sudo ln -s /var/lib/tomcat7/conf conf
sudo ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policy
sudo ln -s /var/log/tomcat7 log
sudo chmod -R 777 /usr/share/tomcat7/conf

3 . Restart server and Eclipse

4 . Add new server

• Choose the Servers under the Server category;
• Create new server wizard;
• Choose Apache / Tomcat v7.0 Server and press Next;
• Enter /usr/share/tomcat7 into the Tomcat installation directory and press Next;
• Select your project on the left pane under “Available” and press Add> to move it to the right pane under Configured; press Finish;

Eclipse need to start the server, and to do that, first, it has to stop the one running in background.

sudo service tomcat7 stop

If you don't have to automatically start at boot, we can use the following command

sudo update-rc.d tomcat7 disable

If, during server start, you receive warnings like:

WARNING: Problem with directory [/usr/share/tomcat7/common/classes], exists: [false], isDirectory: [false], canRead: [false]
WARNING: Problem with directory [/usr/share/tomcat7/common], exists: [false], isDirectory: [false], canRead: [false]

You may also need to run the following:

cd /usr/share/tomcat7
sudo ln -s /var/lib/tomcat7/common common
sudo ln -s /var/lib/tomcat7/server server
sudo ln -s /var/lib/tomcat7/shared shared
